Credit Limit Calculator
Estimate a reasonable credit limit to request based on your income and existing debt.
About this calculator
Requesting a credit limit that's either too conservative or unrealistically high wastes an application, issuers underwrite credit limit requests against a version of the same debt-to-income logic used for loan approvals, working backward from your income and existing obligations to a maximum they're comfortable extending, but that math isn't something applicants normally see before applying. This calculator applies Limit ≈ (Target DTI × monthly income − existing debt) ÷ assumed minimum payment %, using your annual income, existing monthly debt payments, a target debt-to-income ratio, and the minimum-payment percentage issuers commonly assume cardholders would pay on a new balance, to back into a suggested credit limit request. It reports the maximum monthly debt your target DTI allows and the available capacity beyond your current obligations, giving you a defensible, income-grounded number to request rather than guessing at a round figure that might get rejected or approved far below what you could reasonably manage.
Worked example
$70,000 income, $500 existing monthly debt, 36% target DTI
Result: Suggested limit ≈ $52,333
