Frequently Asked Questions

How is a monthly loan payment calculated?
Monthly payment = P × [r(1+r)^n] / [(1+r)^n – 1], where P is the principal, r is the monthly interest rate, and n is the number of payments.
What is the difference between APR and interest rate?
The interest rate is the cost of borrowing the principal. APR (Annual Percentage Rate) includes the interest rate plus any fees, giving a more complete picture of the loan cost.
Does a longer loan term mean lower payments?
Yes, a longer loan term reduces monthly payments but increases the total interest paid over the life of the loan.
What is an amortization schedule?
An amortization schedule is a table showing each payment broken down into principal and interest portions, along with the remaining balance after each payment.
