Rent Affordability Calculator
Income:
A rent affordability calculator determines how much rent you can comfortably pay based on your income. The most widely used rule is the 30% rule — no more than 30% of gross (pre-tax) monthly income on rent. Many financial advisors now suggest 25–28% to allow for savings.
💡
Tip: In high cost-of-living cities, many renters spend 40–50% of income on rent out of necessity. In these cases, focus on minimizing other expenses and aggressively growing income.
- 1Determine your gross monthly income (before taxes)
- 2Apply the 30% rule: max rent = income × 0.30
- 3More conservative: 28% rule leaves more for savings
- 4DTI approach: housing + all debts should not exceed 36% of income
$60,000/year ($5,000/month)=$1,500/month max (30% rule)$1,400 at 28%, $1,800 with no other debts (36% DTI)
$80,000/year + $400/month in debts=$2,000/month max (36% DTI rule)36% of $6,667 = $2,400 − $400 debts = $2,000

Fun Fact
The 30% rule originated from the US National Housing Act of 1937, which set income limits for public housing at 30% of income. It was never based on what's optimal for household budgets.
