How Loan Calculations Work

This calculator uses the standard amortizing loan formula to compute your monthly payment:

M = P[r(1+r)^n] / [(1+r)^n - 1]

Where P is the loan principal, r is the monthly interest rate, and n is the total number of payments. The total cost is the monthly payment multiplied by the number of payments. Total interest is the total cost minus the original loan amount.

This formula works for any fixed-rate loan: personal loans, student loans, business loans, and more.
