A Note on Deferred Interest

Most contractor “0% financing” offers are deferred interest, not true 0% APR — if the full balance isn’t paid off before the promotional period ends, all the interest that accrued since day one gets added to your balance at once, typically at 20–27% APR. This calculator shows the ongoing rate after any promotional period, since that’s the number that actually determines your long-run cost.
