Formula & Mathematical Calculation
Monthly Payment (P&I) = P × [ r(1 + r)n ] ÷ [ (1 + r)n − 1 ]
Total Monthly Housing = Monthly P&I + Property Tax + Home Insurance + PMI
Where: P = Principal loan amount (Home Price − Down Payment), r = Monthly interest rate (Annual Rate ÷ 12), n = Total monthly payments (Years × 12).
