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 loan payment is a financing outflow; it is not the same as profit, taxable income or the operating return from the financed asset.
