The classic rule of thumb is to spend no more than 30% of income on rent, but that guideline is easy to misapply without doing the actual math against your own income.
This calculator converts your annual income and a target rent-to-income percentage into a monthly and annual rent budget.
How it works
Enter your annual income and, optionally, the rent-to-income percentage you want to target (30% by default). The calculator divides your income by 12 for a monthly figure, then applies the percentage to find your affordable rent.
- Enter annual gross income ($).
- Enter target rent-to-income ratio (%).
- Click Calculate to see your results.
Examples
$72,000 annual income
At $72,000 per year and the standard 30% guideline, an affordable rent is about $1,800 per month, or $21,600 per year.
Who should use it
- Setting a rent budget before apartment hunting.
- Checking whether a listed rent fits comfortably within your income.
Industry applications
- Residential leasing and property management
- Personal budgeting
Advantages
- Gives both a monthly and annual rent budget from a single income figure.
- Lets you adjust the target percentage instead of assuming a fixed 30%.
Limitations
- Doesn't account for other debt, dependents, or cost-of-living differences by location.
Common mistakes to avoid
- Using net (take-home) income instead of gross income, which understates true affordability relative to typical landlord screening.
- Treating 30% as a fixed rule rather than a starting point adjusted for personal circumstances.
Best practices
- Factor in your other fixed expenses and debt payments alongside this guideline before committing to a specific rent amount.
Tips
- If you carry significant debt payments, consider targeting a lower percentage than 30% to keep your overall budget balanced.
