# Car Loan Payoff Calculator

Find your monthly auto loan payment from the car price, interest rate, and term. Optional deposit and balloon fields adjust the financed amount, and results include total interest, the effective annual rate, and month-by-month repayments.

## How to use this car loan calculator

1. Pick a currency symbol for display. This does not convert exchange rates.
2. Enter the car value, interest rate, and loan term in years and months.
3. If it applies, subtract an initial deposit or add a balloon payment due at the end of the term.
4. Set the car loan start date so the tool can estimate your payoff month.
5. Click Calculate and the monthly payment, total interest, repayment split, charts, and amortization table all update together.

## How much interest will I pay on my car loan?

Our car finance calculator compounds your interest rate monthly over the loan period. That compounding is what produces the **effective annual rate** you see in the results, which comes out a bit higher than the quoted APR once interest accrues each month on a shrinking balance.

The **Split of Total Repayment** chart shows what share of everything you pay ends up going to principal versus interest. Early in the schedule, interest eats up a bigger slice of each payment even though the payment amount itself never changes.

## Car loan payment formula

Fixed-rate auto loans use standard amortization. When a balloon is part of the deal, the monthly payment gets calculated on whatever must be repaid *before* that balloon comes due, since the present value of the balloon is subtracted from the loan amount first:

**P = loan amount (car value − deposit), B = balloon at end, r = monthly rate, n = months**

### Worked example

Take a $15,000 car loan at 5.4% for 5 years, or 60 months, with no deposit or balloon:

- Monthly payment ≈ $285.83
- Total interest ≈ $2,149.54
- Total payments ≈ $17,149.54
- Effective annual rate ≈ 5.54%

### What is a balloon payment?

A **balloon payment** is a large lump sum due at the very end of the loan. Dealers sometimes lean on balloons to keep monthly payments lower during the term. Once the loan ends, though, you have to pay that balloon in full or refinance it, so plan for that date well before you sign anything.

### How to calculate interest on a car loan manually

1. Work out the monthly payment using the formula above, with the rate written as a decimal (6% becomes 0.06).
2. Multiply the monthly payment by the number of months to get the total repayment.
3. Subtract the loan amount (car value minus deposit) to land on total interest.

## Examples and use cases

### Real-world use cases

- Dealer negotiation: A buyer runs the payment on a $28,000 SUV with $3,000 down to see if a 72-month term actually fits their monthly budget.
- Balloon financing: A shopper models a low monthly payment with a $5,000 balloon due in year 5 to plan out refinance or payoff options ahead of time.
- Trade-in equity: Someone applies $4,000 in trade-in value as a deposit to compare interest saved against financing the full sticker price.

## Frequently Asked Questions

### How is the car loan monthly payment calculated?
The [Car Loan Payoff Calculator](https://shoutingnow.com/tools/car-loan-calculator/) subtracts your deposit from the car's value to get the loan amount, then runs standard amortization on that. If you have entered a balloon, its present value comes out first, before the monthly payment gets computed.

### What is the difference between APR and effective annual rate?
Your quoted APR is the nominal yearly rate, but because interest compounds monthly, the **effective annual rate** shown in results runs a touch higher. It reflects what you actually pay in a year once each month's interest is calculated on the remaining balance.

### How does an initial deposit affect my car loan?
A deposit, or down payment, cuts down the amount you finance. Less principal means a smaller monthly payment and less total interest paid over the loan's life.

### What is a balloon payment on a car loan?
It is a lump sum due at the end of the term. Monthly payments stay lower throughout the loan, but you will need to pay off or refinance that balloon once the term wraps up.

### How much interest will I pay on my car loan?
You will find total interest in both the summary and the repayment split chart. It works out to all your payments minus the loan amount, car value less deposit, including any balloon paid at maturity.
