Navy Federal Credit Union offers loans for new and used cars, boats, motorcycles, RVs, and trucks. Members can take advantage of longer repayment terms, no fees, and low APRs on vehicle loans from this lender.

As part of your search for a new or used vehicle, you can use the Navy Federal auto loan calculator to determine how much you’ll need to pay each month. It factors in your vehicle’s price, down payment, interest rate, and loan term to give you a clearer picture of your costs. This is a good way to ensure beforehand that you’ll be able to comfortably manage the installments.

Using the Navy Federal Auto Loan Calculator early in your car-buying process can give you a clear view of your monthly payments and help you stay within your budget.

An auto loan involves borrowing money from a lender to purchase a car. Once you’re approved for your loan and purchase your car, you’ll repay the principal amount you borrow, along with interest on that amount, through fixed monthly payments over a set term. If you’re planning to apply for a Navy Federal car loan, it’s important to know what your monthly installment payment will be ahead of time.

“As far as how much of a monthly payment you can afford, most Certified Financial Planners recommend that you spend no more than 10% of your take-home pay per month on your vehicle’s principal and interest payment,” explains Brad Reichert, debt expert and founder of Reichert Asset Management LLC.

“When factoring in your total vehicle costs, including gas, insurance, and maintenance costs, you should spend no more than 15%-20% of your take-home pay on your vehicle each month,” Reichert shares. 

Using the Navy Federal auto loan calculator can make budgeting easier once you know what you can expect to pay each month. However, understanding a few key terms beforehand will help you use the calculator more effectively.

Purchase Price

The purchase price of the vehicle will have a major impact on how much you’ll pay in installments each month. A vehicle that costs less will make your monthly payments more affordable. However, a car that costs more may provide you with more value or last longer.

For example, a car costing $20,000 with an interest rate of 5% and a term of 72 months will cost you $322 per month, assuming you’re not putting anything down. With the same interest rate and loan term, a car costing $30,000 will cost you $483 per month.

Compare cars, the features they offer, and the value they deliver against their purchase price to determine the one that is truly right for you.

Down Payment

Your down payment can reduce your monthly payments and may allow you to negotiate a lower interest rate. Consider saving a larger down payment before you purchase a vehicle. This can make your auto loan more affordable and increase your chances of getting approved for a loan with the most favorable terms available.

Using the same example as before, the monthly installment for a car costing $30,000 is $483 if you don’t put anything down. When you put down $6,000 up-front, your monthly installment can be reduced to $387 a month.

When it comes to how a down payment affects your monthly loan payment, a larger down payment has the same impact as choosing a lower-priced car without a down payment. This is because your loan amount will be smaller.

Putting a larger down payment on a vehicle will increase your chances of being approved at a reasonable interest rate. It can also help you to afford a newer or nicer car that may be in better mechanical shape than a lower-priced, older car with higher mileage.

Loan Term

The loan term is the amount of time it’ll take you to repay the loan. A longer term will provide you with smaller monthly payments because these payments will be stretched over a longer period. However, you may end up paying more in total interest over the life of the term.

A shorter loan term will result in a larger installment each month, but it’ll allow you to save more money in total interest paid.

For example, if you’re purchasing a car worth $30,000 at a 5% interest rate and putting down $6,000, you’ll pay $387 per month with a term of 72 months. The total interest you’ll pay over the life of the loan is $3,829.

If you were to reduce the term by just one year to 60 months, your monthly installment would be $453 per month, but the total interest you’ll pay will be $3,175.

Navy Federal Car Loan Interest Rates

Your interest rate is one of the most important factors that will impact the results generated with the Navy Federal auto loan calculator. The Navy Federal car loan interest rate you’ll qualify for will depend on factors like your credit score, down payment, loan term, whether the vehicle is new or used, and more.

Let's consider an example of a car loan to see how interest rates impact monthly payments and total interest costs.

Loan AmountDown PaymentLoan TermInterest RateMonthly PaymentTotal Interest Paid
$30,000 $6,00072 months6.30%$401$4,883
$30,000 $6,00072 months4.60%$382$3,510

If you qualify for a lower interest rate, it can reduce your monthly payment by about $20 and save you $1,373 in total interest over the life of the loan. Even small differences in interest rates can lead to significant savings over time.

Using the Navy Federal auto loan calculator is easy and straightforward. Keep the relevant information handy to make the process easier.

  1. Gather all the information you’ll need for using the auto loan payment calculator, such as the vehicle’s price, as well as the amount of your down payment (and/or the value of your trade-in), interest rate, and loan term.
  2. Enter the vehicle’s purchase price.
  3. Fill out your down payment, loan term, and interest rate for the loan.
  4. If you’re receiving a cash rebate, enter the amount in the calculator.
  5. When you’re trading in your car, enter the trade-in value the dealer has quoted.
  6. If you still owe money on your trade-in vehicle, enter the amount in the calculator. This amount will be rolled over to your new loan.
  7. Once you’ve filled out all your information, the calculator will provide an estimate of your monthly car payment.
  8. Click “Show details” to see your total loan amount and the total interest you’ll pay over the life of the loan.
