Introduction
This Navy Federal auto loan calculator helps you figure out your monthly car payment before you visit the dealer. Just enter the vehicle price, your down payment, trade-in value, sales tax rate, loan term, and interest rate. The calculator does the math for you right away. It shows your monthly payment, total interest, and the full cost of your loan. You can also view a step-by-step breakdown of the math and a full amortization schedule that lists every payment over the life of your loan.
Use this tool to compare different loan terms and down payment amounts side by side. A bigger down payment or a shorter loan term means you pay less interest over time. A longer term lowers your monthly bill but adds more interest in the end. Try different numbers to find a payment that fits your budget. The affordability snapshot shows whether your payment falls within the recommended range based on common income levels, so you can borrow with confidence.
How to Use Our Navy Federal Auto Loan Calculator
Enter a few details about your car purchase and loan below. The calculator will show your estimated monthly payment, total interest, total loan cost, and a full payment schedule.
Vehicle Purchase Price: Type in the full price of the car you want to buy. This is the sticker price before any taxes, fees, or credits are applied. If you are unsure what your vehicle is worth, try our car value calculator for an estimate.
Down Payment: Enter the amount of money you plan to pay upfront. A bigger down payment means a smaller loan and a lower monthly bill. Use our down payment calculator to figure out how much you should put down.
Trade-In Value: Enter the value of a car you plan to trade in at the dealer. This amount is subtracted from your purchase price. If you have no trade-in, leave this at $0. Our car depreciation calculator can help you estimate what your current vehicle might be worth.
Sales Tax Rate: Enter your state or local sales tax as a percent. This tax is added to the vehicle price before your loan amount is calculated. You can also use our sales tax calculator to find your exact tax amount.
Loan Term: Pick how many months you want to take to pay off the loan. Shorter terms have higher monthly payments but save you money on interest.
Annual Interest Rate (APR): Enter the yearly interest rate for your loan. Your rate depends on your credit score, the loan term, and whether the car is new or used. Our APR calculator can help you understand the true annual cost of borrowing.

How Does a Navy Federal Auto Loan Work?
An auto loan is money you borrow to buy a car, truck, or SUV. You pay back the loan in equal monthly payments over a set number of months. Each payment covers two things: part of the money you borrowed (called the principal) and a fee the lender charges for letting you borrow (called interest). You can explore how interest works in more detail with our simple interest calculator or compound interest calculator.
Navy Federal Credit Union offers auto loans to its members for both new and used vehicles. Your interest rate depends on your credit score, how long you choose to repay the loan, and whether the vehicle is new or used. Members with higher credit scores usually get lower rates, which means they pay less over time. If you are shopping for a pre-owned vehicle specifically, our used car loan calculator can give you a more tailored estimate.
Key Terms to Know
- Purchase Price: The full sticker price of the vehicle before any credits or taxes.
- Down Payment: Cash you pay upfront. A bigger down payment means you borrow less and your monthly bill is smaller.
- Trade-In Value: What your old car is worth. The dealer takes this amount off the price of your new vehicle.
- Sales Tax: A percentage your state or city adds to the price. Tax rates vary by location.
- Loan Term: How many months you have to pay back the loan. Shorter terms cost more each month but save you money on interest. Longer terms lower your monthly payment but raise the total amount you pay.
- APR (Annual Percentage Rate): The yearly cost of borrowing, shown as a percentage. This is the single most important number that decides how much extra you pay on top of what you borrowed. Compare rates easily with our interest rate calculator.
- Amortization Schedule: A table that shows how each payment is split between principal and interest, month by month, until the loan is paid off. Our standalone amortization calculator lets you explore this in even more detail.
Tips to Save Money on Your Auto Loan
Put down at least 20% of the car's price if you can. Choose the shortest loan term you can afford. A good rule of thumb is to keep your car payment at or below 10–15% of your monthly take-home pay. This helps you stay on budget and avoid owing more than the car is worth. You can use our DTI calculator to check whether a new payment fits within your overall debt-to-income ratio.
Use the calculator above to try different prices, down payments, and loan terms. You can see right away how each change affects your monthly payment and total interest. This makes it easier to find a loan that fits your budget before you visit the dealership. If you already have an auto loan and want to lower your rate, try our auto refinance calculator. And if you are considering leasing instead of buying, our car lease calculator can help you compare the costs.
