The 30-second answer
At today's typical HELOC rate of 8% APR, a $50,000 HELOC costs $333.33 per month during the draw period (interest-only). When the draw period ends and full repayment kicks in over 20 years, the payment rises to about $418 per month. Variable rates can move your payment up or down each month — see the table below for what happens at different rates.
Why HELOCs have two different payments
A HELOC has two phases, and each phase has a different payment math.
Draw period (usually years 1–10): You can borrow against the line repeatedly, and most lenders only require interest payments on what you've drawn. This is why HELOC payments start low.
Repayment period (usually years 11–30): The line is closed to new borrowing, and your balance amortizes — meaning you pay both principal and interest each month, like a normal mortgage. Payments often jump significantly when this kicks in.
This two-phase structure is the single most misunderstood thing about HELOCs. We'll show you the numbers for both.
$50,000 HELOC monthly payment at common rates — draw period (interest-only)
| APR | Monthly Payment | Annual Interest |
|---|---|---|
| 6.0% | $250.00 | $3,000 |
| 7.0% | $291.67 | $3,500 |
| 8.0% (typical 2026) | $333.33 | $4,000 |
| 9.0% | $375.00 | $4,500 |
| 10.0% | $416.67 | $5,000 |
| 11.0% | $458.33 | $5,500 |
Formula: $50,000 × APR ÷ 12 = monthly interest-only payment. Assumes the full $50,000 is drawn. If you only draw $20,000, your payment is calculated on $20,000 — not the full $50,000.
$50,000 HELOC monthly payment after the draw period (fully amortizing)
When repayment kicks in, your monthly payment depends on both the interest rate AND how many years the lender gives you to pay it off. Most HELOCs use a 10- or 20-year repayment period.
| APR | 10-Year Repayment | 20-Year Repayment |
|---|---|---|
| 6.0% | $555.10 | $358.22 |
| 7.0% | $580.54 | $387.65 |
| 8.0% (typical 2026) | $606.64 | $418.22 |
| 9.0% | $633.38 | $449.86 |
| 10.0% | $660.75 | $482.51 |
Notice the payment jump from draw-period interest-only ($333) to 20-year repayment ($418) at 8% — that's a $85/month increase. With a 10-year repayment instead, the jump is to $607 — a $274/month increase. This jump is the "payment shock" that catches borrowers off guard ten years after closing.
Five things that change your actual $50,000 HELOC payment
1. Your credit score. Borrowers with 760+ FICO scores typically secure 1-2 percentage points below borrowers with 660-700 scores. On $50,000 over 30 years, that's $4,000+ in extra interest.
2. Your combined loan-to-value (CLTV). Lenders price HELOCs based on how much equity you're keeping after the line. A homeowner at 60% CLTV gets a better rate than one at 85% CLTV.
3. The index your rate is tied to. Most HELOCs are Prime + a margin. If Prime is 7.5% and your margin is 0.5%, your starting rate is 8.0%. If Prime moves to 8.0%, your rate is 8.5% and your payment goes up the next month.
4. The lender. HELOC pricing varies significantly between banks, credit unions, and direct lenders. A 0.5% difference on $50,000 over 10 years is $2,500.
5. Whether you draw the full line. You pay interest on the balance, not the credit limit. If you have a $50,000 line but only draw $15,000, you only pay interest on $15,000.
