What are the fixed costs of living alone? Let's understand the basics first.

When you start living alone, fixed expenses will take up a large portion of your monthly living expenses. In particular, monthly expenses such as rent, utilities, and smartphone fees are surprisingly high, and not keeping track of them can lead to mounting expenses.

Additionally, fixed expenses include items that require payment every month, even if you don't use them. If you don't review your contract terms and rate plan, you may continue to incur unnecessary expenses. In this article, we'll explain in an easy-to-understand manner the types of fixed expenses for people living alone, how they affect living expenses, and provide an estimate of the average amount.

First, let's start with some basic knowledge: what are fixed costs and how are they different from variable costs?

The difference between fixed and variable costs

Living expenses can be broadly divided into two types: "fixed expenses" and "variable expenses." Fixed expenses are expenses that occur in roughly the same amount each month, and typical examples include rent, smartphone charges, internet fees, and basic utility fees. These are items that are essential to life, and as long as you have a contract or registration, you will be required to pay for them regardless of your actual usage.

On the other hand, variable expenses are expenses that change from month to month, and include food, daily necessities, social expenses, and entertainment expenses. For example, if you make an effort to cook at home, your food expenses will be cheaper, but if you continue to eat out, they will become more expensive. Shopping at convenience stores and other places can also add up and become an unexpected expense. The difference is that fixed expenses are difficult to change immediately, while variable expenses are easy to adjust through your daily actions.

The impact and importance of fixed costs on daily life

Fixed expenses account for a large proportion of your total monthly living expenses. Especially when living alone, there are many fixed expenses that you "pay the entire amount for yourself," such as rent and communication fees, which can make you feel pressured by your income. Therefore, the first step to living a stable life is to have a clear understanding of the amount and details of your fixed expenses.

For example, if your take-home pay is 200,000 yen a month, and your fixed expenses exceed 150,000 yen, the amount available for variable expenses and savings will be significantly reduced. Conversely, if you can keep your fixed expenses below 100,000 yen, you will have more leeway in your life and it will be easier to save and save. Data from the Statistics Bureau and other sources also shows that rent and communication costs tend to account for a particularly high proportion of expenses. In this way, reviewing your fixed expenses is an important point that can affect your entire lifestyle.

Breakdown and average amount of fixed costs | What are the costs of living alone?

When considering the cost of living alone, the first thing you need to understand is the breakdown of your fixed expenses. These expenses, which occur every month, are diverse and include rent as the core, utilities, communication fees, subscriptions, insurance, and more. The benefit of knowing the average amount is that you can objectively compare whether your expenses are high or low. Recently, an increasing number of people are using household management apps and comparison sites to search for ways to review their fixed expenses.

Housing and utility bills are payments that must be made, so they cannot be ignored. However, if you try to cut back on everything, your quality of life may decline, so it is important to find a balance that suits you, taking into account the disadvantages. Here, we will explain in detail the average amounts and points to note for each expense item.

Rent (housing costs) | Estimates and average prices for the largest expenses

Of all fixed costs, rent is the largest expense for those living alone. According to the Ministry of Internal Affairs and Communications' household survey, the average rent for single-person households varies by region, but nationwide it is generally around 50,000 to 70,000 yen. In urban areas, it often exceeds 80,000 yen, and prices tend to rise especially for apartments and condominiums near train stations or newly built apartments.

Generally speaking, it is considered ideal to keep rent within 30% of your monthly take-home pay. For example, if your take-home pay is 200,000 yen, keeping your rent at around 60,000 yen will leave you with more money for other living expenses. When choosing a property, compare not only the nominal rent but also the actual costs, including management fees and common area charges. Property search sites and real estate companies often display the total amount in an easy-to-understand manner, so it's a good idea to check the site in advance.

Electricity, gas, and water bills (utility bills) | How prices change with the seasons

Utility bills are fixed costs with a large variable factor. The average utility bill, which includes electricity, gas, and water, is around 8,000 to 15,000 yen per month. Even if you live alone, this can fluctuate depending on how much air conditioning you use and how long you take showers. Utility bills tend to rise especially in the summer and winter, when usage increases.

Additionally, there is a large price difference between city gas and propane gas, with propane being more expensive. If you cook at home more, your utility bills and food purchasing costs will fluctuate, which may increase the amount of time your refrigerator runs and the amount of gas you use when cooking. People who shop at convenience stores and supermarkets frequently may end up using too much electricity and gas unnecessarily. It is important to be conscious of reducing waste, even if only little by little, by reviewing your lifestyle habits and contract plans.

Smartphone and Internet Fees (Communication Fees) | How to Choose a Plan

Smartphone and internet charges are typical fixed costs that we continue to pay without even realizing it. Switching to a low-cost SIM or reviewing your plan can be a hassle, but it can save you a lot of money in the long run, making it ideal for people living alone who want to keep their expenses down. It's entirely possible to keep your smartphone bill below 3,000 yen per month.

Another important consideration is how your home communication environment will affect your work and hobbies. For those who work remotely, unstable internet speeds can reduce productivity and cause stress. In such cases, prioritizing stability over low cost is a good choice. By choosing a contract that suits your lifestyle, being able to use the service without worry will lead to the greatest satisfaction.

Don't overlook fixed expenses such as subscriptions and insurance premiums

Monthly service (subscription) fees and insurance premiums are also items that are often overlooked as fixed costs. There are many cases where people continue to sign up for digital services such as video streaming services and cloud storage even though they are not using them, which can lead to wasteful spending. It is especially important to check your usage status frequently, especially in cases where you were automatically charged after a free trial.

Additionally, for young people living alone, a lack of understanding about medical expenses and insurance enrollment can lead to unbalanced spending. Some say private insurance is unnecessary, but if there is a risk of hospitalization or surgery, some level of preparation is necessary. To compare coverage, it is useful to use insurance companies' glossaries and Q&A pages. It is also important to be prepared for periodic reviews so that you can make adjustments according to your life stage.

How much does it actually cost? Example and simulation of living expenses for a single person

When starting to live alone, everyone has the question, "How much will my monthly living expenses be?" In addition to fixed monthly expenses, you also need to consider variable expenses such as food and daily necessities, as well as unexpected expenses. Average expenses vary greatly depending on whether you live in a city like Tokyo or Osaka, or in a regional city or suburban area. Here, we'll provide a detailed explanation based on realistic simulations, including spending trends by area, a breakdown of expenses, and tips for saving money.

Can you live on around 50,000 yen a month? Differences between rural and urban areas

Recently, we've heard people say that "you can live alone on around 50,000 yen a month," but this is mainly true in areas with low rent, such as the Tohoku and Kyushu regions. For example, in Aomori and Kumamoto prefectures, it's not uncommon for rent to be in the 20,000 yen range for older properties or homes far from train stations. Even including utilities and internet fees, it's possible to keep your total living expenses in the 50,000 yen range.

On the other hand, if you live in one of Tokyo's 23 wards or a major city in the Kansai region, rent alone will often cost between 60,000 and 90,000 yen, and total living expenses will generally exceed 100,000 yen per month. In the Tokyo metropolitan area and Osaka City, housing options and prices are high, and fixed costs are difficult to reduce even if you try to save money. Understanding the cost of living in each area is an essential point when planning a reasonable lifestyle.

Breakdown and percentage of expenses | What is the average balance of overall living expenses?

For a typical person living alone, expenses are broken down into "rent," "food," "utilities," "communications," "transportation," "daily necessities," and "insurance premiums." For example, rent accounts for a very large proportion of income, at around 40-50%, followed by food at around 20%, and utilities and communications combined at 10-15%. The average cost balance is to use the remainder for insurance and entertainment expenses.

Assuming your total living expenses are 100,000 yen, your housing costs would be 50,000 yen, food costs 20,000 yen, utilities and communications costs 15,000 yen, and other costs 15,000 yen. While this will vary depending on your lifestyle and where you live, this can be considered one spending model. When reviewing your own household finances, it's a good idea to use this breakdown and percentage as a reference to adjust how you spend your budget.

Points to review when you feel the price is higher than expected

After starting to live alone, it's not uncommon to find that living expenses are higher than you expected. It's especially important to review your expenses in months when initial costs are high, during the winter when electricity bills rise, or when you sign up for more subscriptions. The first thing you'll want to check is fixed expenses like rent, smartphone bills, and insurance premiums. These are expenses you incur every month, so cutting them can lead to significant savings.

To identify unnecessary expenses, it's important to make your spending visible. For example, using a household accounting app or Excel spreadsheet to keep track of your income and expenses at a glance will make it easier to understand how much you're spending on what. It's also effective to review your contracts, such as canceling unused subscriptions or switching to a low-cost SIM. Checking your fixed expenses is the first step to saving money when you feel like you're struggling financially.

Tips for saving on fixed expenses | How to keep monthly payments low

Fixed costs are an expense item that is often left unpaid once a contract is signed, with few opportunities to review. Monthly payments tend to be high, especially in urban areas such as Shinjuku and Minato wards in Tokyo, and Osaka City.

However, if you want to review your living expenses and save money, the first thing you should check are your "fixed expenses." Just a one-time review of the amounts of rent, utilities, communication fees, insurance, etc. can result in savings of anywhere from a few thousand yen to tens of thousands of yen over the course of a year.

Here we will introduce specific ways to save money on each expense item and ideas for reducing fixed costs.

Tips for lowering rent | Points to consider when choosing a property and negotiating

Rent is fixed for the duration of the contract, so it cannot be easily lowered midway. That's why it's important to be creative when choosing a property. For example, you can keep rent low by being flexible with your conditions, such as choosing a station a little off the main lines like the Sobu Line or Yurakucho Line, or looking at areas with relatively lower market prices like Nakano Ward or Bunkyo Ward instead of Shinjuku Ward in Tokyo.

You can also broaden your options by not being too picky about the age of the building, the number of floors, or the amenities such as shoeboxes and underfloor storage. You also need to be careful about the time of year you move; by avoiding the peak season (January to March) and looking during the off-season, you'll be more likely to be offered free rent or key money.

Recently, there has been an increase in properties that do not require a deposit or key money, even if they come with conditions such as a storage room or underfloor heating, and this information can be found on real estate portals or listing pages of properties with cable TV.

How to reduce utility bills | Changing electricity providers and using home appliances

Since utility bills fluctuate from month to month, it is easy to see the effects of savings immediately. For example, simply lowering the air conditioner temperature by 1 degree or switching to LED lighting can significantly reduce your monthly electricity bill.

In addition to major power companies such as Tokyo Electric Power Company and Kansai Electric Power Company, switching to a new power company is also an option to consider. In some cases, reviewing your contract plan can lead to a reduction in fixed costs of more than 10,000 yen per year.

Replacing old refrigerators and washing machines with energy-efficient appliances is also a long-term energy-saving measure. This is especially true for people living alone, where the electricity consumed by appliances accounts for a large proportion of living expenses, so the benefits of reassessing your appliances are significant.

Cut waste by reviewing communication costs and subscriptions

Communication costs are another fixed expense that can be effectively reviewed. Simply switching from a major carrier to a low-cost SIM card can save you 3,000 to 5,000 yen per month. Even in urban areas such as Nishi-Shinjuku in Tokyo's Shinjuku Ward, there are plenty of low-cost plans with good communication environments.

You may also be able to switch to a cheaper plan for your home internet connection by reviewing your usage time, speed, and frequency of use.

You should also regularly check for unnecessary contracts with subscription services such as Netflix and music streaming services. If you have subscribed to any services that you are not using, you should consider canceling them now. For example, it is not uncommon for a business service that you subscribed to for your SOHO to no longer need.

Check your insurance and credit card contracts

Insurance premiums and annual credit card fees are often overlooked. Young people living alone, in particular, often do not need excessive medical coverage or cards with high annual fees, so it is effective to review them to suit their lifestyle.

For example, life insurance that you have previously taken out but have not used, or card contracts that include automatically attached paid options, can gradually put a strain on your household's fixed costs. Make sure to regularly review your policies using your My Page and usage details, which can be viewed 24 hours a day.

Also, if you live in a high-security property with a resident manager, you may have overlapping personal fire insurance and security services, so it's important to check that you don't have any overlapping contracts.

Tips for managing your household finances to control your spending

To properly manage your monthly living expenses, it's essential not only to be conscious of the balance between fixed and variable expenses, but also to "properly understand your spending." The breakdown of expenses will naturally vary depending on the area you live in and your lifestyle. Even if your income is the same, how you manage your expenses can make a big difference in your monthly balance and the amount of money you have available to spend. Here, we'll introduce, with concrete examples, how to record your spending using free tools like household accounting apps and Excel, how to create a reasonable savings plan, and the savings benefits of "visualization."

Use a household accounting app or Excel to understand your fixed expenses

The first step in managing your household finances is to record how much you spend on what. Even if you're not good at writing a household budget by hand, apps make it easy to input and categorize data, and some even have functions that display graphs based on the data. Another convenient feature is that you can check your finances daily on your smartphone. Many apps can be linked to bank accounts and credit cards, and automatically categorize fixed expenses, making it easy to check your statements.

Additionally, by using Excel or Google Sheets, you can customize your management to fit your lifestyle. Categorizing and recording expenses into smaller categories, such as "grocery expenses," "cell phone bills," and "rent," makes it easier to understand spending trends. Even if you're busy with housework or work, creating a format that makes it easy to keep track will make it easier to continue.

How to create a reasonable savings plan?

If your goal in saving is to "save money for the future," it's important to make a plan that you can continue without straining yourself. First, think about how much you can save each month, balancing your income and expenses. For example, after reviewing your fixed expenses such as food, medical expenses, and cell phone bills, setting a specific goal, such as setting aside 10% of your take-home pay for savings, will make it easier to make a plan.

The ideal way to save money is to "set aside money first" rather than "save what's left over." Getting into the habit of transferring your salary to a fixed-term deposit or automatic savings account as soon as it's deposited will help you avoid overspending. Another tip is to flexibly adjust the amount you save depending on changes in income or events. You can also use calculation tools or the automatic calculation function of your household account book to create simulations based on your goals.

Why making your spending visible is the first step to saving money

Visualizing your expenses is a fundamental concept for successful savings. By clarifying the amounts you spend without thinking, you can become aware of unnecessary services and wasteful spending. In particular, you need to be careful about fixed expenses that add up to a large monthly burden, such as bulk purchases of daily necessities or subscription contracts.

If you make it a habit to regularly review your spending, it will be easier to make decisions like, "If I keep going like this, I might end up in the red," or "I have some money this month, so I'll eat out." To do this, it is effective to use apps or Excel that allow you to save data and visualize spending trends by category. There are many free templates and tools available, so anyone can easily get started on visualizing their household finances.

Frequently asked questions, examples of mistakes, and solutions

When you start living alone, unexpected expenses and oversights can make you feel like your life isn't what you expected. Fixed expenses in particular cannot be easily revised once you have signed a contract, so unreasonable expenses can become a long-term burden. Here, we will introduce items of living expenses that require particular attention, as well as common mistakes and how to deal with them. We hope you will use this as a guide to understanding your monthly expenses and aiming for a more waste-free lifestyle.

Things to keep in mind to avoid ending up in the red

Many monthly household budget deficits are due to poor spending management. When fixed expenses are particularly high, the overall balance can be disrupted no matter how much you cut back on variable expenses like food and utilities. For example, rent, insurance, subscriptions, and communication fees are automatically deducted every month, which can become a significant burden without you even realizing it.

First, visualize your expenditure details and check what percentage of your take-home pay your fixed expenses make up. Then, set a limit on your variable expenses and make it a habit to stay within your budget. Using cash or a debit card is also an effective way to reduce unplanned credit card use and keep your spending in check.

Costs and conditions to check when signing a contract

When signing a contract for rental housing or various services, it is important to carefully check not only the monthly fee but also the detailed terms and conditions, such as initial costs, contract renewal fees, and penalties for mid-term cancellation. For example, even if you sign a contract thinking the rent is cheap, management fees and common area charges may be added, making the total price higher. Be careful with internet and smartphone plans, as they may change after a campaign ends.

The detailed terms of the contract may lead to unexpected expenses, so it is essential that you understand the contents before agreeing to them. If you have any concerns, we recommend checking the official website or through the support desk before signing the contract. Compare the terms on multiple sites and make sure to choose one that will reduce your future burden.

Common pitfalls for people new to living alone

One thing that's often overlooked when starting to live alone is the amount of initial costs involved. In addition to expenses such as moving costs, security deposits, key money, and the cost of purchasing furniture and appliances, there's also the expense of preparing things like curtains, daily necessities, kitchenware, and internet contracts. Since expenses can range from tens of thousands to hundreds of thousands of yen, it's dangerous to make hasty estimates.

Another common pitfall among beginners is to mistakenly believe that "monthly income" equals "money you can spend freely." In reality, you need to live on "disposable income," which is the amount of fixed expenses such as rent, food, and utilities, as well as savings and money to cover unexpected expenses. The key to maintaining a sustainable lifestyle is to be conscious of saving a little at first and establish a stable lifestyle. Use convenient apps and household accounting tools to record your daily expenses.

Summary | Review your fixed expenses and live comfortably on your own

As you continue to live alone, one of the most important things to consider when it comes to monthly living expenses is to review your fixed expenses. Items such as rent, utilities, communication fees, and insurance premiums are rarely changed once you have signed a contract, and in many cases, they can put a strain on your spending without you even realizing it.

However, by carefully checking each of these expenses and making them visible, you can create more leeway in your overall lifestyle. For example, you can efficiently reduce your expenses by checking the details of the services you currently subscribe to and eliminating waste, or by comparing and searching multiple plans to switch to the most suitable one. Recently, there has been an increase in free household management apps and comparison sites, making it convenient to gather information and review expenses.

Using the methods introduced here, you can understand the current state of your fixed expenses and aim for a "smart lifestyle" where you can spend money only on what is necessary. The accumulation of small ingenuity and awareness will lead to a comfortable, self-sufficient life.
