How Our HELOC Calculator Works
Our HELOC calculator uses standard loan payment formulas to calculate home equity line of credit payments and borrowing power. The calculation applies home equity principles to determine monthly payments, total interest, and HELOC borrowing limits.
The HELOC Payment Formula
Monthly Payment = P × [r(1+r)^n] / [(1+r)^n - 1]Where P = Principal, r = Monthly Rate, n = Number of Payments

HELOC vs Other Financing
HELOCs offer several advantages over other financing options: lower interest rates than credit cards, flexible borrowing terms, potential tax benefits, and the ability to pay down and re-borrow as needed. However, they use your home as collateral and typically have variable rates.
- HELOCs typically have lower rates than credit cards or personal loans
- Flexible borrowing - use only what you need, when you need it
- Interest may be tax-deductible (consult a tax advisor)
- Variable rates can change monthly, affecting your payment
- Your home is used as collateral - risk of foreclosure if you can't pay
- Two-phase structure: draw period and repayment period
