Formula Used
Monthly payment = P × [r(1 + r)^n] ÷ [(1 + r)^n − 1]
P = principal, r = periodic interest rate, n = number of payments.
How the formula is applied
The calculation links Loan Amount ($), Annual Interest Rate (%) and Loan Term (Years) to monthly payment. The payment is based on the principal financed, which may differ from cash received if an origination fee is deducted. Compare net proceeds with total repayments.
