How it works
Loan payments are calculated using standard amortization: M = P × [r(1+r)^n] / [(1+r)^n − 1], where P is the principal, r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly payments. Each payment covers the interest accrued that month plus a portion of principal — early payments are mostly interest, later ones mostly principal.
