Planning to purchase a new or used vehicle? The free MyCruncher Car Loan Calculator helps estimate your monthly car payment, amount financed, total interest, and total loan payments.
Enter the vehicle price, down payment, trade-in value, sales tax rate, interest rate, and loan term to estimate your auto financing costs.
Whether you're shopping for a new car, comparing used vehicles, or evaluating dealership financing, understanding your estimated loan payment can help you plan a realistic budget.
How to Use the Car Loan Calculator
The MyCruncher Car Loan Calculator uses six inputs to help estimate the cost of financing a vehicle.
- Enter the vehicle price. Start with the purchase price of the car or truck you're considering.
- Enter your down payment. Include the cash amount you plan to pay upfront toward your vehicle purchase.
- Enter your trade-in value. If you're trading in another vehicle, enter the applicable trade-in amount for your estimate.
- Enter the sales tax rate. Provide the estimated vehicle sales tax percentage for your location.
- Enter the interest rate. Use an estimated annual interest rate for your auto loan.
- Enter the loan term. Choose the number of months over which you plan to repay the loan, such as 36, 48, 60, or 72 months.
Click Calculate Car Loan to generate your estimated financing results.
The results show the amount financed, monthly payment, total interest, and total loan payments.
You can adjust your inputs to compare different vehicle prices, down payments, interest rates, and repayment periods.
How Is a Car Loan Payment Calculated?
A typical fixed-rate auto loan uses a standard amortization formula to calculate the scheduled monthly payment.
The calculation depends on the amount borrowed, monthly interest rate, and number of monthly payments.
In this formula:
- M = Estimated monthly loan payment.
- P = Original amount financed.
- r = Monthly interest rate, calculated by dividing the annual interest rate by 12.
- n = Total number of monthly loan payments.
For example, a 60-month car loan contains 60 scheduled monthly payments, equivalent to five years.
For a loan with a true 0% interest rate and no financing fees, the monthly payment is simply the amount financed divided by the number of months.
Car Loan Calculation Example
Example: Suppose you're purchasing a vehicle with the following information.
- Vehicle Price: $35,000
- Down Payment: $5,000
- Trade-In Value: $0
- Sales Tax Rate: 7.25%
- Interest Rate: 6.5%
- Loan Term: 60 Months
Step 1: Estimate Vehicle Sales Tax
For this simplified example, assume sales tax applies to the full vehicle price and is included in the amount financed.
The estimated sales tax is $2,537.50.
Step 2: Calculate the Amount Financed
Add the estimated sales tax to the vehicle price, then subtract the down payment.
The estimated amount financed is $32,537.50.
Step 3: Calculate the Monthly Payment
Using a fixed 6.5% annual interest rate and a 60-month loan term, the estimated monthly payment becomes:
This represents the scheduled principal and interest payment on the auto loan.
Step 4: Estimate Total Interest
Over 60 monthly payments, the total interest paid would be approximately:
Step 5: Estimate Total Loan Payments
Adding principal and interest produces approximately $38,198.01 in total loan repayments.
These loan repayments do not include the separate $5,000 down payment.
Car Loan Example Summary
| Calculation | Estimated Amount |
|---|---|
| Vehicle Price | $35,000.00 |
| Sales Tax | $2,537.50 |
| Down Payment | $5,000.00 |
| Amount Financed | $32,537.50 |
| Monthly Payment | $636.63 |
| Total Interest | About $5,660.51 |
| Total Loan Payments | About $38,198.01 |
Including the $5,000 down payment, the total estimated cash paid toward the vehicle, sales tax, and financing would be approximately $43,198.
This example assumes a fixed-rate, fully amortizing loan with sales tax financed and no additional fees. Figures use unrounded payment calculations before displaying cents. Actual results can differ due to taxes, rounding, fees, or lender terms.
36 vs. 48 vs. 60 vs. 72-Month Car Loans
The length of your car loan can significantly affect your monthly payment and the total interest you pay.
Shorter loans generally require higher monthly payments but reduce total interest costs.
Longer loans generally offer smaller monthly payments but result in more interest over the repayment period.
Car Loan Term Comparison
The following example uses a $32,537.50 loan at a fixed 6.5% annual interest rate.
| Loan Term | Monthly Payment | Total Interest |
|---|---|---|
| 36 Months | $997.24 | $3,363 |
| 48 Months | $771.63 | $4,501 |
| 60 Months | $636.63 | $5,661 |
| 72 Months | $546.95 | $6,843 |
As the loan term increases, the monthly payment decreases, but total interest becomes more expensive.
In this example, choosing a 72-month loan instead of a 36-month loan reduces the monthly payment but adds approximately $3,480 in interest.
The table assumes the same interest rate for all terms. Actual loan offers may have different rates depending on repayment length. Interest totals are rounded to the nearest dollar.
How Does Your Down Payment Affect a Car Loan?
A down payment is the amount of money you pay upfront toward the vehicle purchase.
A larger down payment generally reduces the amount financed, which lowers the monthly principal and interest payment when the rate and term stay the same.
Down Payment Comparison Example
Suppose the vehicle costs $35,000 with $2,537.50 in financed sales tax. The loan uses 6.5% interest over 60 months.
| Down Payment | Amount Financed | Monthly Payment |
|---|---|---|
| $0 | $37,537.50 | $734.46 |
| $3,000 | $34,537.50 | $675.77 |
| $5,000 | $32,537.50 | $636.63 |
| $8,000 | $29,537.50 | $577.94 |
This example illustrates how increasing your down payment can reduce your estimated monthly car payment.
However, it's also important to maintain savings for insurance, repairs, emergencies, and other expenses.
How Does a Trade-In Affect Your Car Loan?
Trading in your current vehicle may reduce the amount you need to finance when purchasing another vehicle.
For example, suppose your replacement car costs $30,000 and you have a $7,000 trade-in allowance with no outstanding loan balance.
Before sales tax and other expenses, the remaining purchase amount would be $23,000.
If you still owe money on the vehicle being traded in, the remaining loan balance must also be considered.
For example, a vehicle worth $12,000 with a $9,000 loan payoff has approximately $3,000 in positive trade equity.
If your remaining loan balance exceeds the trade-in value, you have negative equity.
Negative equity can increase the amount financed if it is added to the new loan.
For trade-ins with an existing loan balance, use the MyCruncher Vehicle Trade-In Calculator to estimate trade equity and financing more completely.
How Does Sales Tax Affect a Car Loan?
Sales tax may add hundreds or thousands of dollars to the cost of purchasing a vehicle.
When sales tax is included in financing, it increases the amount borrowed and may increase the interest paid over time.
Actual sales tax rates and taxable amounts vary by state and local jurisdiction.
Some locations may allow eligible trade-in values to reduce the amount subject to sales tax, while others may not.
Dealer fees, registration charges, and other expenses can also affect the final cost.
Always verify the applicable taxes and fees with the seller or appropriate local authority before buying.
How Does Interest Rate Affect Car Payments?
The interest rate determines the cost of borrowing money for your vehicle.
With the same loan amount and repayment period, a higher fixed interest rate generally increases the monthly payment and total interest.
Interest Rate Comparison
The following table uses a $32,537.50 loan over 60 months with three illustrative interest rates.
| Annual Rate | Monthly Payment | Total Interest |
|---|---|---|
| 4.5% | $606.60 | $3,858 |
| 6.5% | $636.63 | $5,661 |
| 8.5% | $667.56 | $7,516 |
Even a relatively small difference in interest rates can affect your overall financing costs.
Compare loan offers from banks, credit unions, dealerships, and other lenders before making a financing decision.
Car Loan Interest Rate vs. APR
An interest rate describes the interest charged on the borrowed principal.
The annual percentage rate, or APR, is a broader measure of borrowing cost that includes certain loan-related fees.
An auto loan's advertised interest rate and APR may therefore differ.
The MyCruncher calculator uses the annual interest rate entered to estimate scheduled loan payments. It does not independently calculate a fee-inclusive APR.
When comparing real lender offers, review the disclosed APR, amount financed, finance charges, and total of payments.
What Is the Total Cost of Owning a Car?
Your monthly auto loan payment is only one part of the expense of owning a vehicle.
Additional costs may include:
- Car insurance. Premiums vary by driver, vehicle, location, and coverage.
- Fuel or electricity. Driving habits and vehicle efficiency affect energy expenses.
- Registration fees. License and registration charges vary by location.
- Maintenance. Oil changes, tires, brakes, and other routine services.
- Repairs. Unexpected mechanical or electrical problems may create additional costs.
- Depreciation. Vehicles typically lose value over time, although actual values vary.
- Parking and tolls. Some drivers pay additional transportation expenses regularly.
Consider all these costs when deciding how much vehicle you can comfortably afford each month.
Helpful Tips for Lowering Your Car Loan Costs
- Compare vehicle prices. Shopping for a less expensive vehicle reduces the initial financing need.
- Increase your down payment. Borrowing less generally reduces monthly payments and interest costs.
- Compare lender offers. Request estimates from different lenders and compare APRs and fees.
- Consider shorter terms. A shorter term may save interest if the monthly payment remains within your budget.
- Check your credit. Your credit history can affect the rates lenders offer.
- Evaluate your trade-in. Compare trade-in offers and understand any remaining loan balance.
- Review optional add-ons. Extended warranties and other optional products can increase financing costs.
- Ask about early repayment. Review your contract for prepayment restrictions or penalties before making extra payments.
- Focus on total cost. A smaller monthly payment does not always mean the least expensive loan.
Frequently Asked Questions
How do I calculate my monthly car payment?
Enter your vehicle price, down payment, trade-in value, sales tax rate, annual interest rate, and loan term into the MyCruncher Car Loan Calculator.
The calculator estimates the amount financed and monthly payment.
What is the monthly payment on a $35,000 car?
For a $35,000 vehicle with a $5,000 down payment, 7.25% financed sales tax, 6.5% fixed interest, and a 60-month loan, the estimated monthly payment is approximately $636.63.
Your actual payment will depend on your financing terms, taxes, fees, and other details.
Is a 60-month car loan a good option?
A 60-month loan spreads payments over five years and may balance monthly affordability with total interest costs.
Whether it's suitable depends on your budget, interest rate, vehicle, and financial goals.
Is a 72-month loan cheaper than a 60-month loan?
A 72-month loan generally has a smaller monthly payment than a 60-month loan at the same rate.
However, the longer term usually results in more total interest over the loan's life.
Does a larger down payment lower car payments?
Yes. A larger down payment reduces the principal amount financed, which generally lowers monthly payments and interest costs when other terms remain equal.
Does trading in my car reduce the loan?
A trade-in may reduce the amount you need to finance.
If you still owe money on the traded vehicle, the remaining payoff balance affects its net contribution.
Does the Car Loan Calculator include sales tax?
Yes. MyCruncher provides a sales tax rate input to help estimate how sales tax affects vehicle financing.
Actual tax treatment may depend on your location and transaction.
What is the difference between interest rate and APR?
