HELOC Draw Period vs. Repayment Period
A HELOC often has a draw period followed by repayment. The payment can jump because borrowing stops and the balance must amortize over a shorter remaining schedule.

During the draw period
You may be able to borrow repeatedly, and some plans calculate a minimum payment from the current balance. Interest-only payments can look manageable while the principal remains intact.
During repayment
New draws stop and the balance is repaid under the contract. The HELOC calculator shows the interest-only payment and a fully amortizing payment side by side.
Stress the variable rate
HELOC rates can change. Test a higher APR, confirm any floor or cap, and keep enough cash flow for the repayment-period payment—not only today’s minimum.
