Rent Affordability Calculator

Max rent using the 30% rule.

These calculators use standard financial formulas (amortization, compound interest, marginal tax brackets) to estimate results based on the numbers you enter. They don't account for your full financial picture, and results shouldn't be treated as financial, tax, or investment advice. For decisions with real money on the line, check the numbers with a lender, accountant, or financial advisor who can see your complete situation.

How this calculator works

The 30% rule: spending more than 30% of gross monthly income on rent stretches your budget uncomfortably.

Some frameworks use net income (lower cap). High-cost cities sometimes push 35–40% at the cost of thinner discretionary spending.

This calculator gives a ceiling, not a target — plenty of financially healthy budgets land comfortably below 30%, especially for anyone prioritizing aggressive saving or carrying other significant monthly obligations.

Example

$5,000/month gross income: 30% rule caps rent at $1,500.00/month.

Frequently asked questions

Where does the 30% rule come from?

Originated in US federal housing policy in the 1980s. It's a guideline, not a legal limit.

Include utilities in the 30%?

Some versions do. If rent includes utilities, use as-is; if separate, budget 5–10% of income on top.

What if my income is variable?

Use the 12-month average and be conservative. Lenders often require documented base income.

Is 30% always the right target?

It's a general guideline, not a fixed rule — someone with low debt and no car payment can often comfortably manage more, while someone with significant other obligations may want to aim lower.
