How the rent affordability calculator works
AffordBase starts with monthly take-home pay. It subtracts your required debt payments, essential living costs and savings target to calculate how much cash is left for rent. It then compares that amount with a 30% of take-home reference. The lower figure is displayed as the planning target so the result does not ignore the other priorities you entered.
Why take-home pay matters
Gross salary is useful for tax and lease discussions, but monthly budgeting happens after taxes and payroll deductions. If you only know your gross salary, start with the Take-Home Pay Calculator, then bring the monthly estimate back here.

Try a what-if scenario
If the rent you are considering feels tight, change it by $100–$300 and watch the money-left result. That makes the trade-off visible before you commit. For a broader salary, city, debt and car scenario, use the AffordBase Dashboard.

Frequently asked questions
How much rent can I afford?
A useful planning estimate starts with monthly take-home pay, then subtracts debt payments, essential living costs and the amount you want to save. AffordBase also shows a 30% of take-home reference so you can compare both views.
Is the 30% rent rule based on gross or net income?
Rent rules vary. Some common housing guidelines use gross income, while this calculator deliberately shows 30% of take-home pay as a conservative budgeting reference and separately calculates your cash-flow ceiling.
Should debt affect how much rent I can afford?
Yes. Required debt payments reduce the cash available for housing, savings and everyday expenses, so the calculator includes them directly.
What if my rent is higher than the estimate?
The estimate is a planning guide, not a lease-qualification rule. Adjust savings, living costs or rent to compare scenarios and see the effect on money left each month.
AffordBase provides planning estimates only. It does not determine landlord approval, lease eligibility, or financial advice. Actual housing costs can also include utilities, parking, renters insurance and other fees.
