$50,000 HELOC Payment: Interest-Only vs. Repayment at Every Rate (2026)
About $354 a month at today's typical rate — but only during the draw period. Here's the payment at every rate, and the jump that's coming when repayment starts.
The Answer: $292–$417 Interest-Only, $388–$483 in Repayment
The monthly payment on a $50,000 HELOC balance depends on the rate and which phase you're in. At a typical 8.5% rate, the interest-only payment during the draw period is about $354/month; once the draw period ends and the balance amortizes over 20 years, the required payment rises to roughly $434/month. Verify your exact numbers with our interest-only HELOC calculator.
| HELOC rate | Interest-only payment (draw period) | 20-yr repayment payment | 10-yr repayment payment |
|---|---|---|---|
| 7.0% | $291.67 | $387.65 | $580.54 |
| 7.5% | $312.50 | $402.80 | $593.51 |
| 8.0% | $333.33 | $418.22 | $606.64 |
| 8.5% | $354.17 | $433.91 | $619.93 |
| 9.0% | $375.00 | $449.86 | $633.38 |
| 9.5% | $395.83 | $466.07 | $646.99 |
| 10.0% | $416.67 | $482.51 | $660.75 |
Two things the single number hides: a 1-point rate increase adds about $42/month instantly on this balance, and interest-only payments make zero progress — pay $354/month for a full 10-year draw period and you'll have paid roughly $42,500 in interest while still owing the entire $50,000.

Most HELOCs run a 10-year draw period (interest-only allowed) followed by a 20-year repayment period (principal and interest required). On a $50,000 balance at 8.5%, that transition takes the required payment from $354 to $434 — a 23% jump — even if the rate never moves. At a 10-year repayment term, common on older lines, the jump is to $620/month, a 75% increase.
Because HELOC rates float with prime, the repayment reset and a rate increase can land together. The CFPB specifically warns borrowers to plan for the end-of-draw transition. If the rate on this balance rose from 8.5% to 10% at the same moment repayment began, the payment would go from $354 to $483 — a 36% increase overnight.
The escape hatch is voluntary principal during the draw period. Adding $300/month of principal to the interest-only payment on this balance clears it in about 11 years and avoids the reset entirely — model your own exit with the HELOC payoff calculator.
