What is a HELOC Payment Calculator and How Does It Work?
A HELOC payment calculator estimates your monthly payments, interest costs, and total cost of a home equity line of credit. Our HELOC loan payment calculator 2026 uses current market rates and standard lender formulas to model both phases of a HELOC: the draw period (interest-only payments) and the repayment period (fully amortizing principal + interest). The calculator answers the key questions: "How much is my HELOC payment?" and "How much will it jump when the draw period ends?"
How does the home equity line of credit payment calculator work? Enter your HELOC amount, APR, draw period length, repayment period length, and closing costs. The calculator instantly shows your draw-period payment, repayment-period payment, total interest paid in each phase, total cost, payment jump at repayment, and effective APR including fees.
Repayment Period (Fully Amortizing): Monthly Payment = P × [r(1+r)^n] ÷ [(1+r)^n - 1], where P = principal balance, r = monthly rate (APR ÷ 12), n = total number of payments (years × 12).
Effective APR: Includes closing costs and annual fees in the true borrowing cost.
HELOC Rates and Terms in 2026
Current HELOC rates: 7.00% to 10.50% APR. Most HELOCs are variable rate, priced as Prime Rate + margin (typically 0-2%). Prime rate is around 7.50% in 2026. Rates adjust monthly or quarterly based on the Federal Reserve's rate decisions .
Draw period: 5-10 years. During this phase, you can borrow, repay, and re-borrow funds up to your credit limit. Most lenders require interest-only payments during the draw.
Repayment period: 10-20 years. You can no longer borrow, and payments switch to fully amortizing principal + interest, paying off the outstanding balance.
What Happens When the Draw Period Ends?
When the draw period ends, two critical changes occur. First, you can no longer borrow. Second, your payment switches from interest-only to principal + interest, which typically increases your monthly payment by 30-50%. A $50,000 balance at 8.5% goes from ~$354/month (interest-only) to ~$492/month (15-year repayment) — a 39% jump. Many borrowers plan for this by making principal payments during the draw period to reduce the balance at repayment .
How to Calculate Your HELOC Borrowing Limit
Most lenders allow you to borrow up to 80-85% of your home's appraised value, minus your existing mortgage balance (this is the combined loan-to-value or CLTV). Formula: HELOC Available = (Home Value × CLTV%) - Current Mortgage Balance. Example: $400,000 home × 85% = $340,000 max CLTV - $250,000 mortgage = $90,000 HELOC available.
HELOC Interest Tax Deductibility (2026)
HELOC interest is tax-deductible only if the funds are used to buy, build, or substantially improve the home securing the loan. Interest on HELOCs used for debt consolidation, vacations, or personal expenses is not tax-deductible. Always keep receipts and consult a tax professional before claiming the deduction .
