HELOC affordability calculator
If you know the monthly payment you can comfortably handle, you can work backwards to find the approximate loan amount. Enter your target payment, expected APR, and repayment term below to see an illustrative borrowable amount.
Approximate borrowable amount: $41,211
Illustrative estimate based on full amortization over the term entered. Actual HELOC amounts depend on lender underwriting. Not an offer to lend.
How it's calculated
This tool checks whether a HELOC payment fits your budget. It estimates the new payment from your expected balance and APR, then adds it to your existing monthly debts and divides by your gross monthly income to estimate your debt-to-income (DTI) ratio. Many lenders prefer DTI below about 43%. Enter your income, current debts, and HELOC details to see where you would land.
Frequently asked questions
What DTI do I need to qualify for a HELOC?
Many lenders look for a debt-to-income ratio below roughly 43%, though some allow higher. DTI is your total monthly debt payments divided by gross monthly income. A lower ratio generally improves approval odds and pricing, but each lender sets its own thresholds.
Should I budget for the interest-only or repayment payment?
Budget for the higher repayment-period payment, not just the interest-only draw payment. The draw payment can look affordable, but once principal is added the cost rises. Planning around the larger figure helps you avoid payment shock when the draw period ends.
