You can use this calculator to plan your extra payments and see how they'll impact your loan. It's especially useful for determining the best time to make extra payments to maximize your savings.

The Formula Used

The calculator uses the following formulas to determine the impact of extra payments:

Remaining Balance Calculation

For each month, the remaining balance is calculated as:

Remaining Balance = (Previous Balance × (1 + Monthly Interest Rate)) - (Regular Payment + Extra Payment)

Total Interest Saved

Total Interest Saved = (Original Loan Term × Regular Payment) - (Actual Payoff Month × Regular Payment) - (Total Payments Made - (Original Loan Term × Regular Payment))

These formulas account for the compounding effect of interest and the impact of your extra payments on the loan payoff timeline.

Worked Example

Let's look at an example to see how making extra payments affects your auto loan.

Example Scenario

Loan Balance: $20,000
Interest Rate: 5% APR
Loan Term: 60 months
Regular Monthly Payment: $386.67
Extra Payment: $200 per month

Using the calculator, you would find that:

The loan would be paid off in 42 months instead of 60
You would save $2,500 in interest
Your total payments would be $18,300 instead of $23,200

This example shows how making extra payments can significantly reduce your loan term and interest costs.

Frequently Asked Questions

Can I make extra payments on my auto loan?

Yes, most lenders allow extra payments on auto loans. However, check with your lender to confirm their policy and any potential fees for prepayment.

How do extra payments affect my interest rate?

Making extra payments typically doesn't change your interest rate, but it can reduce the total interest you pay over the life of the loan.

Is it better to make extra payments at the beginning or end of my loan?

Making extra payments at the beginning of your loan term typically saves you more money in interest because you're paying down more of the principal balance where interest is calculated.

Can I make extra payments in a lump sum?

Yes, many lenders allow lump sum payments. This can be particularly effective if you have a large sum available to pay off your loan early.

Will making extra payments affect my credit score?
