What percentage of your income should your rent be? Explaining the average rent in Japan and how to choose a property that suits your salary

A general guideline for rent is said to be "one-third of your net salary."

In other words, if your monthly income is 200,000 yen, it would be ideal to live in an apartment with a rent of around 60,000 to 70,000 yen.

*Net income: Income after deducting social insurance premiums, resident tax, employee pension insurance premiums, and withholding tax on income from your gross salary.

If your rent exceeds one-third of your take-home pay, be aware that this will reduce your other living expenses and your ability to save for the future.

Furthermore, if you want to use your income for living expenses other than rent or to increase your savings, it's recommended to limit spending to 20-25% of your net income.

Rent isn't the only expense you incur each month, so it's important to consider how it balances with other living expenses.

From here, we will introduce specific points to consider when thinking about a reasonable rent.

The rent is determined by subtracting living expenses from net income.

As mentioned earlier, rent is not the only monthly living expense.

Therefore, one approach is to determine your rent after getting an idea of the estimated costs of other living expenses.

If your take-home pay is 250,000 yen, applying the table above, your living expenses excluding rent will be around 160,000 yen, leaving you with 90,000 yen to allocate to rent or savings.

After understanding your current expenses, consider how much you can allocate to rent.

Check the average rent prices in each area and decide on your desired amount.

Rental property prices in Japan vary greatly depending on the region.

The highest rents in Japan are in Tokyo, and rents tend to increase the closer you get to the city center.

On the other hand, rural areas are characterized by relatively low rent prices and the availability of spacious properties.

If you have decided on a station or area where you want to live, research the average rent and check if it fits within your budget.

If you can't find a property within your desired budget, you can increase your chances of finding one by changing your requirements to include properties with separate bathrooms and toilets, or properties within 15 minutes of a train station, or by broadening your search area.

Check if there are housing allowances or rent subsidies.

It's also important to check if the company offers housing allowances or rent subsidies as part of its employee benefits.

A housing allowance is a benefit that subsidizes the rent that employees pay.

On the other hand, rent subsidy refers to a system where the company covers a portion of the rent paid by its employees who live in rented properties.

Since the details of both housing allowances and rent subsidies vary from company to company, you need to check with your employer.

Generally, these subsidies are often set as "a certain percentage of the monthly rent" or "a maximum of a certain amount of money will be subsidized."

However, housing allowances and rent subsidies may change depending on the company's financial situation, so it's best to choose a rent that you can comfortably continue to pay even if the system is discontinued.

How much does rent differ between living alone and living with someone else?

[For a single person (living alone) with a net income of 200,000 yen]

If your take-home pay is 200,000 yen, a reasonable rent would be about one-third of that, or around 70,000 yen.

After deducting rent, the remaining amount is 130,000 yen. Subtracting other fixed expenses from this amount will give you the amount you can freely spend each month.

[For a couple living together with a combined net income of 400,000 yen]

If two people have a combined net income of 400,000 yen, a reasonable guideline for rent would be about one-third of that, or 120,000 yen.

The rent per person comes to 60,000 yen, which gives the impression of being a little more financially comfortable compared to living alone.

Here's a summary of estimated rents for single people and couples:

A general guideline for rent is said to be "one-third of your take-home pay," but sometimes compromises are necessary to keep it within your desired budget.

From here, I'll introduce how to choose a property that will help you keep your rent down.

Don't be too picky about your requirements for a property.

Rent is determined by taking into account various factors such as distance from the station, age of the building, structure, and floor plan.

Trying to fulfill all your desired conditions for a property may result in it exceeding your budget, so be careful.

When choosing a property, consider the non-negotiable conditions and your priorities for desired features, and then make your decision based on how they balance with the rent.

Rooms on the first floor, older buildings, and wooden buildings tend to have relatively lower rents, so please consider them.

Considering room sharing

Room sharing allows you to split rent and utility costs, making it possible to reduce your overall living expenses compared to living alone. Some rental properties even allow room sharing, so discussing it with a friend is one option to consider.

However, while it can save money, living together can sometimes lead to conflicts with roommates, so you should consider this carefully.
