The formula for the monthly payment on a loan involves three key factors: the loan amount, the interest rate per period, and the number of periods. It can be represented as M = P[r(1+r)^n] / [(1+r)^n-1], where M is the monthly payment, P is the loan principal, r is the monthly interest rate (annual rate divided by 12), and n is the total number of payments (or periods). This formula helps you calculate how much you'll need to pay each month to clear your loan under specified terms.
