SAME BALANCE. DIFFERENT PAYMENTS.
Look at both stages.
Some HELOCs allow interest-only payments during the draw period. A later repayment period may add principal to the payment.
Calculate a scenario to see both, side by side.
How this estimate works
The interest-only estimate is balance × annual interest rate ÷ 12. The fully amortizing estimate uses a constant monthly rate and equal monthly payments over the entered term. The higher-rate scenario adds the selected percentage points immediately to both calculations; it is a stress test, not a prediction.
For $50,000 at a hypothetical 8%, estimated monthly interest only is $333.33. Paying the same balance off over 15 years at a constant 8% requires about $477.83 a month. At 10%, those estimates are $416.67 and $537.30. Principal payments explain part of the change even without a rate increase.
No new draws, fees, taxes, insurance, payment rounding, or daily accrual differences are included. Your agreement may require principal during the draw period, a different repayment method, or a balloon payment. The modeled rate stays constant for the entire term; an actual variable-rate balance may not.
