Determine How Much Time and Money You Can Save with One Time Payments

Tutorial for the Auto Loan One Time Payment Calculator.

How to Use the Calculator

You can enter the amount of the one time payment and the month you would like to apply it in. You can add as many additional “one time” payments as you like. You also enter the term of your loan and how many months you have left on your loan.

Summary : by modifying any of the inputs, such as down payment, you can see the savings instantly.
If you would like to see your potential savings by adding additional money to your monthly payments then try the Auto Loan Early Payoff Calculator.

Additional Payments
Add additional principal payments here. Choose the amount and the month you are going to pay it.

You'll shorten your loan by months and save in interest by paying making payments to the principal in the months you specified.


How we calculate interest

This calculator uses a monthly interest rate equal to your APR divided by 12 (a 24% APR becomes 2% per month). That is exactly how U.S. credit card companies and most lenders charge interest each month, so the totals here reflect what you would really pay.

If another calculator shows you a different number, it is almost always because it converts the rate a different way. Some use an “effective annual” formula — (1 + APR)1/12 − 1 — which gives a slightly lower monthly rate and makes debt look cheaper and quicker to pay off than it actually is. Others compound daily (APR ÷ 365), which runs a few dollars higher. We deliberately use the plain APR ÷ 12 method because it matches your statement. Small differences between tools are normal and come down to this single choice.
