FAQ
How is my monthly payment calculated?
It uses the standard amortization formula: M = P·r·(1+r)^n / ((1+r)^n − 1), where P is the loan amount, r is the monthly interest rate and n is the number of months.
Does paying extra each month help?
Yes. Extra payments go straight to principal, cutting both the payoff time and the total interest you pay. Try the “Extra monthly” field above.
Is this loan calculator free?
