Work the 30% rule in reverse: gross income to a maximum rent, or a rent to the income needed. Utilities and parking come off the allowance.
All calculations happen locally in your browser. Your income and rent never leave your device.
The 30% rule ignores local cost of living: in many expensive markets renters routinely pay 40% or more of gross income. Treat the result as a benchmark, not a verdict.

Estimates only — not financial advice.
The tool applies the 30% affordability ratio in whichever direction is useful to you: from income down to a maximum rent, or from a rent up to a required income. Everything is gross-pay arithmetic on numbers you enter — no external data, no estimates about your city.
As a planning benchmark, yes — as a universal law, no. In many high-cost cities a large share of renters already spends 40% or more of gross income on rent, and no calculator can make that affordable. Use the 30% figure as the line below which housing is unlikely to crowd out your other goals, and treat anything above it as a trade-off you are consciously making.
Gross — the original convention measures rent against pre-tax income. This calculator follows that convention, so enter your gross pay. A net-pay version would be stricter: for the same take-home check you would qualify for less rent, since taxes and deductions never reach your wallet.
The rule applies to each household income against the whole rent. With roommates, run the calculator on your own income against only your share of the rent (after splitting utilities the same way) — the math is intentionally manual because sharing arrangements vary too much to automate honestly.
No. It is one widely cited budgeting ratio applied to numbers you enter, with no knowledge of your debts, local costs, lease terms or income stability. Estimates only — decide with your own judgment.
No. Every result is computed locally in your browser from the numbers you type. Your income, rent and extras never leave your device, and there is no account and no network request attached to a calculation.
