A seven- to ten-year loan
These terms are typical for larger secured loans, such as home improvement or student loans, and RVs. The payment is low and the interest cost is large, so make extra payments when you can.

When is half of a $20,000 loan repaid?
With a $321.78 payment, the balance falls below half ($10,000) after 49 payments, about 4.1 years into a 7 years loan. Because interest is highest at the start, the second half of the loan is paid down much faster than the first.

|---|---|---|
| 1 year | $17,851 | $3,861 |
| 2 years | $15,501 | $7,723 |

Frequently asked questions
How is a loan payment calculated?
The payment is principal × r ÷ (1 − (1 + r)^−n), where r is the monthly rate (APR ÷ 12) and n is the number of months. Each payment covers that month’s interest first, and the rest reduces the balance.
What is the difference between interest rate and APR?
The interest rate is the cost of borrowing the money. APR also includes certain fees, so it is the better number for comparing offers. This calculator treats the rate you enter as the rate that accrues on the balance.
Will extra payments save interest?
Yes, if your lender applies them to principal and charges no prepayment penalty. Use the extra payment field to see the effect.
