How to use this calculator
Detailed mode caps rent by both a configurable income share and the remaining personal budget. Gross income uses your estimated deduction rate to model take-home pay. Income-only mode is a rule-of-thumb comparison, not a personal spending plan. Scenarios compare 25%, 30% and your selected share.

Formula and method
Percentage rules are illustrative preferences, not universal affordability or lease-approval standards. Tax deductions are a user assumption, not a tax calculation. Deposits, moving costs and irregular spending require separate planning.
Worked example
With monthly take-home income 5,000, a 30% housing ceiling and 200 in utilities, the rent ceiling is 1,300. Debt 300, essentials 1,200 and savings 500 leave 1,500 unallocated after these housing costs.
Questions about rent affordability calculator
How much rent can I afford?
Start with take-home pay and reserve money for debt, essential spending, savings and utilities. Compare the remaining rent budget with a percentage preference. A 30% rule is only a starting assumption and does not guarantee a lease application will be approved.
What assumptions should I check?
Percentage rules are illustrative preferences, not universal affordability or lease-approval standards. Tax deductions are a user assumption, not a tax calculation. Deposits, moving costs and irregular spending require separate planning.
