Rent calculator
Rent Calculator
Estimate a safer monthly rent limit using income, target rent percentage, and other monthly housing costs.
When to use this calculator
Use this calculator before signing a lease or comparing apartments. It turns income into a practical rent ceiling, then subtracts recurring housing costs that people often forget.
The calculator is not financial advice. It is a budgeting screen that helps you avoid leases that look affordable before utilities, parking, insurance, transport, and fees are included.
Formula used
Maximum rent = monthly income × target percentage − other monthly housing costs.
The formula is intentionally simple so it can be used for quick planning. Real bills, quotes, and installation costs can include fixed fees, taxes, tiers, labor, product limits, and site-specific conditions that a calculator cannot see.
Input guide
| Input | How to use it |
|---|---|
| Monthly income | Use stable take-home income for conservative planning, or gross income only if that is how your landlord screens applications. |
| Target percentage | Many renters use 25–35% as a rough range, but the right number depends on debt, savings goals, and local costs. |
| Other costs | Include utilities, parking, renter insurance, trash, internet, pet fees, and required service charges. |
| Emergency margin | Leave room for repairs, deposits, medical costs, travel, or income gaps. |
Examples
Income screen
At $4,000 monthly income and a 30% target, total housing is $1,200 before subtracting other costs.
Utility adjustment
If utilities and fees are $250, the safer rent target becomes about $950 instead of $1,200.

FAQ
Is 30% always the right rule?
No. It is a common reference point, not a universal rule.
Should I use gross or net income?
Use take-home income for personal budgeting. Use landlord rules only for application screening.
Does the calculator include deposits?
No. Deposits and moving costs should be planned separately.
