FAQ
How is the monthly loan payment calculated?
With the amortization formula: P = S · (i · (1+i)^n) / ((1+i)^n − 1), where S is the loan amount, i is the monthly interest rate (annual rate / 12 / 100), and n is the number of months. This produces equal monthly payments over the full term.
What is APR and how does it differ from the interest rate?
APR (Annual Percentage Rate) reflects the total yearly cost of the loan including the interest rate plus most fees (origination, processing). It is usually higher than the nominal interest rate and is the most reliable number for comparing loan offers.
Can I pay off a loan early without penalty?
Most consumer loans in the US allow early payoff. A few lenders charge a prepayment penalty, so check your loan agreement. Paying extra toward principal reduces the total interest you pay over the life of the loan.
What affects the total interest I pay?
The loan amount, the interest rate, and the term. A longer term lowers the monthly payment but increases total interest. A shorter term costs more per month but far less overall.
