How to calculate rent affordability
This calculator applies a target percentage of your income to figure out a rent budget — commonly based on guidelines like the well-known "30% of gross income" rule, though the right percentage for you depends on your other expenses, debt, and location.
How the calculation works
Affordable rent = Gross monthly income × (Maximum rent percentage ÷ 100). This shows the rent amount that corresponds to your chosen percentage of income — it does not account for your specific expenses beyond that percentage guideline.
Example
On a $5,500 gross monthly income using the common 30% guideline: affordable rent = $5,500 × 0.30 = $1,650/month. Someone with significant other debt might use a more conservative 25%, which would suggest closer to $1,375/month instead.
Frequently asked questions
Where does the 30% guideline come from?
It originates from U.S. federal housing assistance standards from the 1980s, which used 30% of income as a threshold for housing cost burden. It's since become a common budgeting rule of thumb, though it wasn't originally designed as universal financial advice.
What if 30% of my income doesn't cover typical rent in my area?
This is a real and common situation in high-cost cities. Some renters adjust by getting roommates, looking further from city centers, or accepting a higher percentage while cutting other budget categories — there's no formula fix for a market-level affordability gap.

Pro Tips for Rent Affordability
- The 30% guideline is a starting point, not a rule — if you have high student loan or car payments, a lower percentage leaves more breathing room; if you have minimal other debt, some people comfortably go higher.
- Remember this uses gross (pre-tax) income; your actual take-home pay after taxes, insurance, and retirement contributions will be meaningfully lower than the number you're calculating against.
- Factor in utilities, renter's insurance, and parking if they're not included in the quoted rent — the 'affordable rent' figure here is just the base rent line.
Common Rent Affordability Mistakes to Avoid
- Using gross income when budgeting month to month — for actual cash-flow planning, compare rent against your net (take-home) pay instead, even though the traditional guideline is stated in gross terms.
- Applying the same percentage regardless of your city's cost of living — in very high cost-of-living areas, many renters exceed 30% out of necessity, which is worth acknowledging rather than treating the guideline as a hard limit.
