This rent affordability calculator shows how much rent fits your budget. Enter your gross income and monthly debt payments. It gives three answers: the classic 30% rule, a debt-adjusted figure that keeps rent plus debts under about 36% of income, and the 40x rule many landlords use to approve tenants.
What is a Rent Affordability Calculator?
How much rent you can afford depends on your income, your other debts and how much you want to save. The best-known guideline is the 30% rule: spend no more than 30% of gross income on rent. Landlords often use the 40x rule: your yearly income should be at least 40 times the monthly rent.
A rent affordability calculator applies these rules and a debt-adjusted version, so you can set a realistic budget before you start apartment hunting.
How does the Rent Affordability Calculator work?
The calculator divides yearly income by 12 and applies your chosen share for the percentage rule. The debt-adjusted figure keeps rent plus debt payments under 36% of gross income, a common lending guideline. The 40x rule divides yearly income by 40.
It takes the lowest of the three as a comfortable budget and subtracts utilities if you enter them.
How to use the Rent Affordability Calculator step by step
- Enter your gross annual income.
- Enter your monthly debt payments.
- Choose a rent share (30% by default).
- Add utilities and insurance.
- Compare the three methods.
- Use the comfortable figure as your search budget.
