Affordability calculator
Rent-to-Income Ratio Calculator
Calculate what percent of income goes to rent and compare the result with common affordability bands.
Rent-to-income ratio
Use this as a planning estimate. Debt, utilities, savings, deposits, and local rent prices can move the comfortable number lower.
| Band | Interpretation |
| Under 30% | Generally more comfortable |
| 30% to 40% | Common, but tighter |
| 40% to 50% | Rent-heavy |
| Over 50% | High pressure budget |
How this calculator works
This page divides rent by income to show the rent-to-income percentage. The output is a planning estimate, not an approval decision or a complete household budget.
- Use the rent target as a starting point before adding utilities, debt payments, savings, and transport.
- Compare gross-income rules with take-home pay when the household budget is tight.
- Treat landlord screening rules as qualification checks, not proof that the rent is comfortable.
When to use this page
Use it when you already know the rent and income and want to interpret the percentage instead of starting from a rule of thumb.
How to read the result
The percentage shows how much income rent consumes before other costs. A lower ratio leaves more room for utilities, debt, savings, transport, insurance, and irregular expenses.
What this result does not include
A rent-to-income ratio does not show take-home pay, tax withholding, debt minimums, household size, local costs, deposits, or whether the rent includes utilities.
Next check after this result
If the ratio lands near a cutoff, test the same rent with take-home pay and fixed expenses. The percentage is most useful when it leads to a real cash-flow check.
Qualification max vs comfort max
A rent amount can pass a landlord income rule and still feel too tight in a real budget. Compare the rule result with your take-home pay and fixed expenses.
What a rent rule leaves out
Income rules do not know your credit profile, guarantor options, deposits, utilities, insurance, childcare, car payments, local application rules, or how variable your income is.
Worked examples
$1,500 rent and $5,000 income
$1,500 rent divided by $5,000 monthly income is 30%, before utilities, debt, savings, or take-home-pay adjustments.
Comparing two listings
If one listing is 28% of income and another is 36%, the second may still qualify but leaves less room for other monthly costs.
