Input Variables

Loan Amount: This is how much money you need to buy a car. It can include the price of the car, taxes, fees, and extra expenses like insurance or warranties.

Loan Term: This is how long you will have the loan in months. Common terms are 36, 48, 60, or 72 months, but can be different too. A longer term may mean smaller monthly payments but a more total amount of interest paid over time.

Down Payment: When you use a calculator, you can enter the amount of money you can pay upfront. This is called a down payment, and it will reduce the loan amount and the monthly payments.

Trade-In Value: If you have an old car, enter its estimated value into the calculator. That amount can help lower your loan amount.

Taxes and Fees: Depending on where you live, taxes or fees may come with buying a car. The calculator may include these costs in your calculations.

Calculate: After entering all the information, click “calculate.” The calculator will use a formula to find out how much your monthly payment will be based on what kind of loan terms and interest rates were given.

Output Variables

Monthly Payment: The calculator will show how much your monthly payment will be for principal and interest combined. It may also show how much total interest you’ll pay over time if it’s a long-term loan agreement.

Interest Rate: This is what the lender charges for borrowing money. It’s shown as a percentage. The interest rate affects your monthly payments a lot.

Amortization Schedule: An amortization schedule is a way to break down each frequency of repayment for a loan. It shows how much of the payment goes towards the principal and how much goes towards interest. It also shows the remaining loan balance until it is paid off completely.

Step-by-Step Guide to Using a Car Loan Repayment Calculator

Step-by-Step Guide to Using a Car Loan Repayment Calculator

1. Determining the Amount to Finance: 

Decide On A Price For The Vehicle

To figure out how much you have to finance, first decide on a price for the vehicle with the seller or dealership. You can get it cheaper by talking with them. Then, add any taxes and fees your state charges for tags and titles.

Calculate State Sales Tax

Find out what sales tax rate your state charges and add that amount to the estimated purchase price of the car, plus any tags or title fees that have been added on top of that amount.

Deduct The Trade-In Value From The Price Of The Car (If Applicable)

If you are trading in your old car, the dealer will give you a certain amount of money for it. This is called the trade-in value. Subtract that from the price of the new car to find out how much you need to pay.

Add Any Fees And Charges That The Dealer Charges

The dealer may also charge additional fees like destination fees (for delivering a new car from factory to dealership) or documents fees (like loan processing fees and service and handling fees). Some states have limits on these extra charges.

Subtract Any Rebates Or Incentives

When buying a new car, you can get discounts. The manufacturer and the car dealer may give you money back or lower interest rates if you buy from them. Look into these discounts before buying the car to save money.

Subtract The Down Payment From The Loan

When you buy a car, you will need to make a down payment. This is the amount of money that you can pay right away.

2. Calculating Car Loan Payments

Understand How Car Loans Work. 

Auto loans are loans that you use to buy a car. The loan amount includes the cost of the car and interest. You pay back the loan in equal payments over time.

The amount you pay each month stays the same, but part of your payment goes towards paying down the principal (the amount you borrowed for the car) and interest. As time passes, less of your payment will go towards interest, and more will pay the principal.

Learn The Formula For Loan Amortization.

Amortization is when you pay off a loan in equal amounts. To figure out how much to pay each month, you need three pieces of information: the loan amount, the interest rate per month, and the total number of months.

To calculate this, use the formula:

A = P*(r(1+r)^n)/((1+r)^n-1).

A is your monthly payment, P is your principal amount (original loan amount), r is your interest rate per month (divide the annual rate by 12), and n is your total number of months.

Calculate Your Monthly Loan Payment.

To buy a car, you need to borrow $15,090. This is the principle. You get an auto loan that lasts 48 months and charges 7 per cent interest each year. You will have to pay back the loan (principal plus interest) in 48 equal payments (once per month). The monthly interest rate is 0.583 per cent (7 divided by 12). Your monthly payment will be $361.07.

Factors Affecting Car Loan Ratings

Factors Affecting Car Loan Ratings

Down Payment Or Trade-In Value

Trading in your old vehicle or making a down payment can lower the amount of money you need to borrow for a new car. Dealers like it when customers make a down payment because it shows they are serious about buying the car. This payment can also help people get loans and better dealer loan rates.

Credit Score

Your credit score determines if you can get a loan and how much interest you pay for the loan. The Fico Auto Score is between 290 and 900. Most lenders want at least 700, but they might still let you borrow money even if your score is lower.

Lenders understand that people need cars, so they are willing to be more flexible compared to other loans like personal loans. Even people with scores as low as 500 or no credit history can get an auto loan. What matters is if you have enough income to make monthly repayments.

Length of Term

The loan term is how long you will pay for the loan. It can range from 36 months to 72 months. The interest rate changes, but it can be 5.07% for a 36-month term or 4.56% for a 60-month term. You have to think about how much you can afford each month when deciding on the length of your loan term. If you can pay more each month, your loan term will be shorter, and you won’t pay as much interest over time.


Income is important when getting a loan. It shows that you can pay back the money each month. People with regular jobs usually have an easier time getting a loan than people who work for themselves. Also, if you are self-employed, having a registered business is better than being a freelancer if you want to get a loan.


If you want to buy something with a loan, try preapproval. Preapproval is when the bank or credit union checks your credit score to see if you can get a loan. They will tell you what interest rate and term (time) you qualify for. Try this with different lenders to see who has the best rates. This helps when negotiating at the dealership because they may offer an even better rate if they really want your business.

Understanding the Amortization Schedule

Understanding the Amortization Schedule

What Is an Amortization Schedule?

Amortization is a way of accounting for loans and certain types of assets. For loans, it means that payments are spread out over a while. It is similar to depreciation when applied to an asset.

Key Components

When it comes to amortization, there are three main components to consider. These components are essential for understanding how a loan or mortgage is paid down over time. They include:

  1. Principal Component: The principal component is the portion of each periodic payment that reduces the original loan amount or the principal balance. In the early stages of a loan, a smaller portion of the payment is allocated to the principal, while a larger portion goes towards interest. As the loan is gradually paid down, the principal component of each payment increases.
  2. Interest Component: The interest component is the portion of each payment representing the cost of borrowing the money. In the early stages of a loan, a significant portion of the payment is applied to interest, which is calculated based on the remaining loan balance. As the loan is paid down, the interest component of each payment decreases.
  3. Remaining Balance: The remaining balance, also known as the outstanding or loan balance, is the original loan amount that has yet to be repaid. It decreases with each payment as the principal component reduces the debt. The remaining balance is important because it determines how much interest is calculated for the next payment.

The Impact of Interest Rates on Loan Repayment

Low vs. High-Interest Rates

Interest rates play a crucial role in determining the cost of borrowing money. As interest rates rise, the cost of borrowing increases, resulting in higher loan payments. In contrast, when interest rates decrease, borrowing costs decrease, reducing the amount of money required for loan payments.

High interest rates can significantly reduce the amount of money lenders are willing to lend to potential borrowers, as they represent higher default risk. Conversely, low-interest rates foster healthy lending criteria, enabling lenders to extend more credit to borrowers, which allows for greater borrowing power.

The impact of interest rates on borrowing costs is especially significant for mortgage loans, car loans, and other types of large-scale loans. A higher interest rate can significantly increase monthly loan payments, making borrowing considerably more expensive.

Calculating Total Interest Paid

When you take out a loan, the interest rate applied to that loan directly impacts the total cost of the loan. Even the slightest fluctuation in interest rates can make a significant difference in the amount that you pay. For instance, if interest rates increase by a mere 1%, the overall cost of your loan will also increase.

High-interest rates can cause your loan repayment to become more complicated, especially if you cannot pay down the principal and interest in full each month. The higher the interest rate, the higher the amount of interest that accrues on your outstanding balance each month. Over time, this can lead to an ever-growing debt that seems nearly impossible.

Comparison Rates

Comparison rates are another important factor to consider when evaluating the impact of interest rates on loan repayment. The comparison rates take into account not only the interest rate charged on a loan but also any additional fees and charges that may be associated with the loan.

This provides borrowers with a more accurate representation of the total cost of borrowing and allows them to compare different loan options more effectively. Higher interest rates, combined with additional fees and charges, can significantly increase the overall cost of borrowing and make loan repayment more challenging for borrowers.

Therefore, it is crucial for borrowers to carefully consider both the interest rate and the comparison rate when assessing the affordability of a loan and planning for repayment.

Loan Term and Its Influence on Monthly Payments

Short-Term vs. Long-Term Loans

The longer the repayment period, the lower the monthly payments will be. This is because extending the repayment period gives you more time to repay the loan in small amounts each month, making it a more affordable option than shorter repayment periods with higher monthly payments.

However, while a loan with lower monthly payments may seem appealing initially. It’s important to remember that a longer repayment period can have drawbacks.

One of them is that you will end up paying more interest over the life of the loan. This is because interest rates accumulate over time, and the longer the repayment period, the more interest you will have to pay.
