Free Rent Affordability Calculator

What is a rent affordability calculator?

A rent affordability calculator helps you set a practical housing cap before apartment hunting.

Enter monthly income and your target rent percentage to estimate a maximum rent amount that leaves room for other priorities.

Max affordable rent = Monthly income × Target rent %

Compare this with your full budget in our how to make a monthly budget guide.

If monthly income is $4,500 and your rent cap is 30%:

Line item	Amount	Calculator field
Monthly income	$4,500	Monthly income ($)
Max rent target	30%	Max rent (%)

Maximum affordable rent is $1,350 per month.

Keeping rent near this target can preserve room for savings and essentials.

Max affordable monthly rent — The rent ceiling implied by your income and chosen percentage.
Annual rent budget — Monthly rent cap multiplied by 12 months.
Income left after max rent — Amount left each month before non-housing expenses.

Affordability is personal. Choose a lower rent target if you are rebuilding savings or paying debt.

Net income is usually safer for day-to-day budget decisions.

No. It is a guideline; your debts, goals, and city costs matter.

Many households include utilities in total housing, not rent alone.
