HELOC Loan Payment Calculator

Know exactly what your home equity line of credit will cost — before you borrow.

Most HELOC calculators only show one payment. The reality is two: a low interest‑only payment during the draw period, then a much bigger amortized payment when repayment begins. HELOC Calculator makes that "payment shock" crystal clear, so there are no surprises down the road.

Punch in your balance, rate, and terms and instantly see your payment now, your payment later, and exactly how much it jumps.

WHAT YOU CAN DO

• See both payments — interest‑only during the draw period vs. the fully amortized payment after, with the jump highlighted up front • Full amortization schedule — every payment, split into draw and repayment phases, with a clean balance‑vs‑interest chart • Model the real world — extra principal payments, monthly or bi‑weekly cadence, and rising or falling variable rates with a lifetime cap • Estimate your credit line — the built‑in CLTV helper finds how much you can borrow from your home value, mortgage balance, and max combined LTV • Compare scenarios side by side — see which option costs less in interest and total payments, with the best of each highlighted • Save your plans — keep every scenario and pick up right where you left off • On your wrist — a quick Apple Watch estimate for draw and after‑draw payments anywhere
