Most HELOC calculators hand you one number and hide the math. This one shows all of it: your real credit line, the cheap interest-only payment now, the bigger principal-and-interest payment later, lifetime interest, and what you'd save moving a $60,000 card balance onto the HELOC. Change any of the 9 input cells on the Inputs tab and all three result tabs recalculate on the spot, no subscription and no add-ons, just an .xlsx file you open in Excel or upload once to Google Sheets and keep.
