About this calculator
This calculator uses the standard loan amortization formula M = P × [r(1+r)^n] / [(1+r)^n − 1], where P is the loan balance, r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly payments. Because early payments are weighted more toward interest and later ones toward principal, the fixed monthly amount stays constant even as the interest-principal split shifts over the loan's life.
Students and families use it to compare federal versus private loan offers before signing, financial aid offices use the same math to build repayment estimators, and borrowers approaching graduation use it to check how a 10-year versus 20-year term changes both the monthly bill and the total interest paid.
