This rent affordability calculator turns your gross monthly income into a sensible rent range. It follows the widely used 30% rule: as a rough guideline, no more than 30% of your gross (pre-tax) monthly income should go toward rent. Enter your income to see a recommended maximum along with a more comfortable target and an upper stretch limit.
The 30% rule is a starting point, not a hard cap. Spending less — closer to 25% — leaves more room for saving, debt payments and other bills, while going up to 35% may be workable in expensive cities but leaves a thinner cushion. Landlords often expect your income to be around three times the rent, which lines up with the same 30% guideline.

Frequently asked questions
What is the 30% rule for rent?+
It is a common budgeting guideline suggesting you spend no more than 30% of your gross monthly income on rent. On a $5,000 monthly income that works out to about $1,500 in rent.
Should I use gross or net income?+
The 30% rule is traditionally based on gross (pre-tax) income, and that is what landlords usually check. If you prefer a more cautious budget, apply the same percentages to your take-home pay instead.
Is it ever okay to spend more than 30%?+
Yes. In high-cost cities many renters spend 35% or more. It can be fine if you have low other debts and stable income, but it leaves less room for savings and unexpected costs.
