Payment = draw*r*(1+r)^n/((1+r)^n-1) where r=rate/12, n=years*12

How does this work?

HELOC draw is like loan for drawn amount, amortized over repayment period after draw period. Monthly payment amortizes draw.

This is interest-only during draw plus principal in repayment. For simplicity, this amortizes fully over repayment years.

For YMYL, HELOC is variable rate, often prime +1-2%. Rate can rise 2% yearly — stress test at +2%.
