The Answer: $292–$417 Interest-Only, $388–$483 in Repayment

The quick answer

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.

$50,000 drawn balance. Interest-only = balance × rate ÷ 12. Repayment columns use standard amortization over the stated term. HELOC rates are variable (prime + margin), so these payments move whenever prime moves.
Interest-Only Payment = Balance × (Rate ÷ 12)
Variables
Balance — drawn amount ($50,000), not your credit limit
Rate — current annual rate as a decimal (0.085 for 8.5%)
Example: $50,000 × (0.085 ÷ 12) = $354.17 per month — none of which reduces the balance.

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.

The Payment Shock: What Changes When the Draw Period Ends

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.

The rate can move at the same time

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.
