01Canonical Law: M = (H - D) × i(1 + i)^(12Y) / ((1 + i)^(12Y) - 1)
02Given Inputs (Base Units): H = 500,000 $, D = 100,000 $, r (%) = 6.5, Y = 30 yr
03Solve for M (Monthly P&I Payment): M = 2,528.27 $
A fixed-rate mortgage amortizes the financed balance (H - D) across 12Y monthly installments using the standard level-payment annuity formula.
