Calculator documentation
How to use the rent affordability calculator
This section explains every input and interactive feature used in the calculator above.
Field-by-field guide
- Gross monthly income
- Income before taxes and deductions. This drives the common 30% gross-income housing guideline.
- Monthly take-home pay
- Income deposited after taxes, benefits, and deductions. This drives the personalized cash-flow limit.
- Monthly debt payments
- Required monthly payments for credit cards, student loans, auto loans, and other debts.
- Other monthly expenses
- Recurring non-housing spending such as food, transport, childcare, subscriptions, and healthcare.
- Monthly savings goal
- The amount you want to preserve each month for emergency, retirement, or other goals.
- Utilities & renter insurance
- Expected utilities, internet, and renter insurance. This is reserved before the maximum rent is calculated.
- Available move-in cash
- Cash currently available for the deposit, first month, moving costs, and other one-time setup costs.
Calculation workflow
- 1Add gross income for the familiar 30% benchmark.
- 2Use take-home pay and real expenses for a cash-flow limit.
- 3Include utilities so the suggested rent leaves room for the full housing cost.
Planning tips
- ✓Treat the result as a ceiling, not a target.
- ✓Budget separately for deposits, moving, parking, and furnishings.
- ✓Use stable recurring income and test a lean-income month.

Frequently asked questions
Does the 30% rule use gross income?+
Yes. It is a quick screening guideline, while the cash-flow result uses take-home pay and is more personal.
Are utilities included?+
The suggested rent subtracts your utility and renter-insurance estimate, so the full housing budget remains visible.
How much cash is needed to move?+
Many moves require first month’s rent plus a deposit. The estimate shows how many months of suggested rent your cash could cover.
