The two lives of a HELOC payment

A HELOC isn’t one loan — it’s two phases wearing the same account number. In the draw period you can borrow, repay, and borrow again, and the required payment is typically interest-only. In the repayment period the line closes and the balance must be paid down on a fixed schedule. This HELOC payment calculator shows what you pay in each phase — and the gap between them.

The payment shock is the whole story

The most common HELOC surprise is the month the draw period ends. Interest-only payments feel light; amortizing payments are not. Seeing both numbers side by side, years in advance, gives you time to either pay principal early or plan the bigger payment into your budget.

Three ways to soften it

  • Pay more than interest during the draw — every principal dollar cuts the future payment.
  • Refinance before the reset — some borrowers roll the balance into a fixed home equity loan for a predictable payment.
  • Attack it like any debt — schedule the payoff in a planner and watch the balance fall month by month.

Our free planner treats your HELOC like any other debt: give it the balance and rate, and it slots it into a month-by-month payoff plan next to your cards and loans.

Frequently asked questions

How are HELOC payments calculated?

During the draw period (often the first 10 years) most HELOCs require interest-only payments: balance × annual rate ÷ 12. When the draw period ends, the balance amortizes over the repayment period (often 10–20 years) with much larger principal-and-interest payments.

Why does my HELOC payment jump after the draw period?

Because you switch from paying only interest to repaying the entire principal on a clock. On $50,000 at 8.5%, interest-only is about $354/month; amortized over 15 years it becomes about $492 — and over 10 years, $620. That jump is the “payment shock” this calculator shows you in advance.

Are HELOC rates fixed or variable?

Almost always variable, tied to the prime rate plus a margin. When prime moves, your payment moves. This calculator assumes today’s rate stays constant, so treat results as an estimate, not a promise.

Can I pay principal during the draw period?

Yes — and it’s usually smart. Interest-only is the minimum, not the rule. Any principal you pay during the draw shrinks both today’s interest charges and the size of the payment shock later.
