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

HELOC Calculator Examples

HELOC Calculator Example
Calculate HELOC payments for a $500,000 home with $300,000 mortgage and $50,000 HELOC draw

Property Parameters:

  • Home Value: $500,000
  • Mortgage Balance: $300,000
  • Available Equity: $125,000
  • HELOC Limit: $100,000
  • Draw Amount: $50,000

Calculation Steps:

  1. Available Equity = $500,000 × 85% - $300,000 = $125,000
  2. HELOC Limit = $125,000 × 80% = $100,000
  3. Monthly Rate = 6.5% ÷ 12 = 0.542%
  4. Monthly Payment = $567 (10-year term)
  5. Total Interest = $18,040 over 10 years

Result: Monthly Payment = $567, Total Interest = $18,040

This HELOC provides $50,000 in financing with a $567 monthly payment over 10 years.
