Frequently asked questions

How is my monthly loan payment calculated?

Your payment is calculated using the standard amortization formula, based on your loan amount, interest rate (APR) and loan term. Each month a portion goes to interest and the rest reduces your principal.

What's the difference between APR and interest rate?

The interest rate is the cost of borrowing the principal. APR includes the interest rate plus certain lender fees, giving you a more complete picture of the loan's true yearly cost.

Does paying extra each month really save money?

Yes — extra payments go directly toward your principal, which reduces the balance interest is calculated on every month, shortening your loan and cutting total interest paid.

Is refinancing my loan worth it?

It depends on the gap between your current rate and the new rate, your remaining term, and refinancing closing costs, which typically run 2–5% of the loan amount. Use the Refinance tab above to compare your specific numbers.

How much loan can I afford?

A common guideline caps your total monthly debt payments at 36% of gross monthly income. The Affordability tab estimates a loan amount based on your income, existing debt, and chosen rate and term.
