US HELOC Calculator 2026 | Home Equity Line of Credit Payment & Borrowing Power

A HELOC Calculator estimates potential borrowing amounts, monthly payments, and interest costs for a Home Equity Line of Credit. It provides indicative figures based on your home value, mortgage balance, and interest rate. The results are meant for planning and general understanding.

The calculator uses your entered home value, outstanding mortgage balance, credit limit assumptions, and interest rate to estimate available equity and costs. It applies commonly used HELOC calculation principles in the United States. Outputs are indicative and may vary from lender offers.

You typically enter your home’s current value, remaining mortgage balance, interest rate, and draw amount. Some versions may also ask for repayment term details. Providing accurate figures improves the usefulness of the estimates.

The calculator is based on standard formulas and user inputs. Actual borrowing limits and rates may differ due to lender criteria and credit profile. Results should be treated as indicative.

Yes, HELOCs commonly have variable rates, and the calculator may assume a constant rate for simplicity. If rates change, actual costs may vary. You can adjust the rate to explore scenarios.

No. HELOCs include origination fees (0.5-2%), appraisal fees ($300-700), annual maintenance fees ($25-100), and closure fees ($300-500). CFPB requires Truth in Lending (TILA) disclosures. Add these to this calculator's estimates for true total borrowing cost.

Lenders typically allow 80-90% combined loan-to-value (CLTV). If your home is worth $400k with a $300k mortgage, you have $100k equity. At 80% CLTV, maximum borrow is $20k ($400k × 80% - $300k). Credit score and debt-to-income also matter.

Interest is tax-deductible if used for home improvements (IRC Section 163(h)). Interest on personal expenses, credit card payoff, or other uses is NOT deductible. IRS caps total deduction to $750k of home equity debt. Consult your CPA.
