A simple loan calculator computes monthly payments and total interest for a standard installment loan (mortgage, auto loan, personal loan). It uses the standard amortization formula where equal monthly payments cover both principal and interest.
Guide étape par étape
- 1Monthly payment = P × r(1+r)^n / ((1+r)^n − 1)
- 2Each payment covers that month's interest first, then reduces principal
- 3Total cost = Monthly payment × number of payments
- 4Total interest = Total cost − Original principal
