2-1 Buydown Calculator
Cost and payment schedule of a 2-1 temporary rate buydown — year-1 and year-2 payments and what the seller credit must fund.
Formula
A 2-1 buydown is prepaid subsidy, not a cheaper loan — you must qualify at the full note rate, and year 3's payment arrives regardless of where rates went. As a seller concession it often beats an equivalent price cut for the buyer's early-year cash flow.
