Maximum Rent Budget Calculator
Set your own housing target instead of relying on a market average. The calculator reserves the entered share of take-home pay for total housing, then subtracts recurring charges to show the remaining base-rent budget.
User-defined cash-flow budget in Japanese yen only. It is not a market-rent estimate, landlord screening rule, or affordability verdict. It excludes deposits, key money, moving costs, utilities, debt, savings goals, income volatility, and household-specific needs.

How this estimate works
- The total monthly housing target equals take-home pay multiplied by the percentage you choose.
- The maximum base-rent budget equals that target minus entered recurring housing charges, with no negative rent displayed.
- The result shows the remaining take-home amount as context but does not label your choice affordable or unaffordable.
Official household-budget context
- Statistics Bureau of Japan: Family Income and Expenditure Survey
- Statistics Bureau of Japan FAQ: monthly household expenditure categories including rent
Japan's Statistics Bureau reports housing as a household-expenditure category. These sources do not prescribe the percentage you should choose; the calculator uses your own target.
Frequently asked questions
Is 30% the correct rent limit for everyone?
No. The percentage is an editable planning target, not a universal recommendation or landlord approval standard.
Should management fees be included?
Yes. Enter recurring management or housing charges separately so the result reserves part of the total target for them.
