## How to use the Car Loan calculator

To use the car loan calculator, you’ll need to enter some details about your loan. These are explained below:

**Vehicle Purchase Price**- The value of the vehicle you wish to buy. Car loans are secured by the vehicle you purchase, and this amount will be relative to the base loan amount for your car finance.**Initial Deposit / Trade-In Amount**- The deposit amount put toward the vehicle during the purchase, or the amount you are offered when trading in your current vehicle. The final loan amount (minus any fees) is calculated by subtracting the deposit or trade-in amount from the vehicle purchase price.**Interest Rate**- This is the fixed interest rate the lender will apply to your car loan, and is used to calculate both the total amount of interest you will pay over the loan period and your scheduled repayment amount.**Loan Term**- The length of your car loan as dictated by your loan agreement. The loan term is important as it will allow you to accurately calculate your monthly, fortnightly, or weekly payments through an Annual Percentage Rate (APR) calculation. The shorter your loan term, the higher your scheduled repayments will be.**Establishment Fees**- Any upfront fees charged by the lender when creating the secured car loan agreement. Establishment fees are included in the calculation for your repayments to provide a more accurate total loan amount.**Loan Amount**- The amount of money you will be taking out under a car loan agreement, including any fees, and discounting any deposit or trade-in amount.

Once you have filled in your car loan details, simply click ‘See My Repayments’ to view an estimated repayment amount. You can then select Monthly, Fortnightly, or Weekly repayments to see what your repayment amount will be at various frequencies.

## Car Loan Repayment and Interest Formula

The car loan calculator uses what is called an amortisation calculation. Amortisation is best understood as the way you will gradually repay your loan amount over time. For example, when you make your first repayment on your car loan, a greater portion of the amount will go toward repaying the interest. As you continue to meet your repayments, the portion of interest paid on each amount will decrease, and the portion paid on your principal amount will increase.

Car loans are generally secured by the vehicle, and offered for a fixed rate over a fixed term. Calculating your repayments this way will not only give a more complete representation of repayments, but also allow you to determine the amount of interest you will pay over the term - or save if you are able to repay the loan early.

When expressed a mathematical formula, calculating your car loan repayments can seem somewhat complex. Don’t be concerned! Once you understand how amortisation works and the interest is calculated on a loan amount over time, you should be able to make the calculations on your own.

The simple formula for calculating Loan Repayments is: **Loan Amount / Discount Factor**

The complexity of the calculation is in determining the discount factor, which is calculated by dividing the interest rate of your loan by the number of payments per year (12 for monthly, 26 for fortnightly, or 52 for weekly) to first obtain the Periodic Interest Rate.

The formula is expressed as: (((1 + i) ^n) - 1) / (i (1 + i)^n)

- n = the number of repayments
- i = the annual interest rate

In the example below, we’ll look at an individual wanting to purchase a $30,000 vehicle. They don’t provide a deposit, however they do trade their current vehicle in to the value of $10,000. Accounting for this, their car loan is $20,000, and they agree to a 7.5% fixed interest rate and a repayment term of 5 years.

- n =
**60**(12 repayments per year for 5 years) - i =
**0.00625**(where the interest rate (7.5%) is divided by the number of annual payments (12) to provide a decimal representation of the interest rate) - Using the discount factor formula above, we can calculate the discount factor: ((((1+0.00625)^60) - 1) / (0.00625(1+0.00625)^60)) =
**49.9053** - The discount factor is then calculated as
**49.9053** - We then take our loan amount (
**$20,000**) and apply the Loan Repayment Formula, dividing the loan amount by the discount factor. This will provide your monthly repayments:**20,000 / 49.9053 = 400.759** - We then round this figure out to a double-digit decimal amount. Your monthly repayments on this loan will be
**$400.76**

Secured car loans will generally use fixed interest rates offered between 5.00% and 29.90%.
