P = Principal — the total amount borrowed.
2
r = Monthly interest rate (annual rate ÷ 12 ÷ 100).
3
n = Total number of monthly payments (years × 12).

Frequently Asked Questions

How does interest rate affect my payment?
A higher interest rate increases your monthly payment and the total amount paid over the life of the loan. Even a 1% difference can mean thousands of dollars over a long-term loan.
Should I choose a shorter or longer loan term?
A shorter term means higher monthly payments but you pay less interest overall. A longer term lowers monthly payments but costs more in interest. Choose based on your monthly budget.
