How this loan calculator works
Enter the amount you want to borrow, the annual interest rate (APR) and the term. The calculator uses the standard amortization formula to find a fixed monthly payment that pays off the loan exactly by the end of the term, and shows how much of your money goes to interest. Add an origination fee to see the loan's true cost, or an extra monthly payment to see how much faster you can be debt-free.
Payment = P × r ÷ (1 − (1 + r)−n), where P is the loan amount, r the monthly rate (APR ÷ 12) and n the number of months.
Typical loan rates
Rates depend on the loan type, your credit score and your income. Many variable-rate loans and lines of credit are priced from the bank prime rate, currently the current prime rate in the U.S. Unsecured personal loans commonly range from single digits for excellent credit to over 30% APR for poor credit. Federal student loans have fixed rates set each year by law, and secured loans (home equity, auto) are usually cheaper than unsecured ones.
Origination fees and the real APR
Many personal loans charge an origination fee of 1%–10%, usually subtracted from the money you receive. If you borrow $15,000 with a 5% fee, you receive $14,250 but repay the full $15,000 plus interest. The calculator converts this into an effective APR so you can compare offers fairly. U.S. lenders must disclose the APR under the Truth in Lending Act; Canadian lenders must disclose the cost of borrowing.
Shorter term or lower payment?
A longer term lowers the monthly payment but increases the total interest. Compare a 3-year and a 5-year term above — the difference in interest is often thousands of dollars. If you choose a longer term for flexibility, paying a little extra each month gives you the best of both, as long as the loan has no prepayment penalty.
Before you borrow
- Check your debt-to-income ratio; most lenders prefer it below about 36%–43%.
- Pre-qualify with several lenders — a soft credit check does not affect your score.
- If you are consolidating credit card debt, compare the loan with a balance transfer using our credit card payoff calculator.
