HELOC Payment Calculator — Interest-Only Payment
The draw-period view: it prices the interest-only minimum on whatever you've drawn, which is just balance × rate ÷ 12. A $50,000 draw at 8.5% runs $354.17 a month and $4,250 a year, and the balance never shrinks while you pay only that minimum. Useful for judging the true carrying cost of a renovation draw before you take it.

Breakdown
HELOC rates are variable; this estimate holds the rate constant. Not a credit decision or an offer of credit.
Cheap to carry, easy to underestimate
Interest-only pricing scales linearly: every $10,000 drawn at 8.5% adds $70.83 a month. That linearity makes mental math easy mid-project — but it also means a creeping renovation budget quietly doubles the payment when the draw doubles. The figure to keep in view is the yearly cost ($4,250 on $50,000), which reads less ignorable than the monthly one.
Because principal doesn't move, the interest-only phase is exposure, not progress. Paying more than the minimum during the draw period shrinks both the eventual repayment payment and the total interest — the calculator's repayment view shows what the end-state looks like if you don't.
Questions
- What does a $50,000 HELOC draw cost per month interest-only?
- At 8.5%, $354.17 a month — $4,250 a year. Each additional $10,000 drawn adds $70.83 a month at that rate.
- Does the balance go down during the draw period?
- Not if you pay only the interest-only minimum. The full balance carries into the repayment phase unless you voluntarily pay principal.
