How this calculator works
A commonly cited guideline is that rent shouldn't exceed 30% of your gross monthly income — but this "rule" is a rough starting point, not a universal financial law. Your actual affordability depends heavily on your other debts, expenses, savings goals and the cost of living in your area.
This calculator shows your rent-to-income percentage for a target rent amount, and how much income remains after rent, debt payments and other expenses. Use this remaining amount to sanity-check whether you're comfortable covering savings, emergencies and everyday costs.
Someone with no debt and low other expenses might comfortably afford rent above 30% of income, while someone with student loans, car payments or dependents might need to stay well under 30% to stay financially comfortable. Treat this calculator as a starting conversation with your own budget, not a fixed rule.
Example: On a $5,000 monthly income with $400 in debt payments and $600 in other expenses, a $1,500 rent is 30% of income, leaving $2,500 remaining for savings and everyday costs.

Frequently asked questions
How much rent can I afford?
A common guideline is up to 30% of your gross monthly income, but your real affordability depends on your debts, other expenses and financial goals. This calculator shows your specific rent-to-income ratio and remaining income.
Is the 30% rent rule always accurate?
No, it's a rough guideline, not a universal rule. Someone with low debt might comfortably afford more than 30%, while someone with significant other expenses may need to budget for less.
What counts as 'other expenses' in this calculator?
Recurring monthly costs outside of debt payments and rent — utilities, groceries, insurance, subscriptions, childcare, and anything else in your regular budget.
Does this calculator check my credit or income?
No, this calculator only uses the numbers you enter and performs the calculation locally in your browser. Nothing is sent anywhere or stored.
Is this financial advice?
No, this is a general planning tool. Rent affordability depends on your full financial picture — consider consulting a financial advisor for personalized guidance.
