Motor Loans R Us

Understanding how vehicle finance is calculated is crucial when deciding to finance your next car or van. The amount you’ll pay over the term of your finance agreement depends on several factors, including the loan type, interest rate, and repayment period. At Motor Loans R Us, we’re here to breakdown the key components that influence the cost of your vehicle finance. 

Loan Amount

The loan amount is the total amount you borrow to purchase the vehicle. This is usually the price of the vehicle minus any deposit you put down. The larger the loan amount, the more you’ll pay in interest over the life of the loan. 

Example: If you’re buying a car for £20,000 and put down a £5,000 deposit, the loan amount would be £15,000. 

Interest Rate

The interest rate is the cost of borrowing money, expressed as a percentage of the loan amount. It can be either fixed, meaning it stays the same throughout the loan term, or variable, meaning it can change based on market conditions. The interest rate you’re offered typically depends on your credit score, the type of finance you choose and the lender’s policies. 

Example: A 5% interest rate on a £15,000 loans would mean you pay £750 in interest each year of the loan, assuming simple interest. 

Annual Percentage Rate (APR)

the APR is a broader measure of the cost of borrowing, including the interest rate and any additional fees or charges that the lender applies. The APR gives you a more accurate picture of the total cost of your finance agreement. 

Example: If your finance agreement includes a £300 admin fee and the interest rate is 5%, your APR might be slightly higher, perhaps 5.5%, reflecting these additional costs. 

Loan Term

The loan term is the length of time which you’ll repay the loan. Vehicle finance typically has a term of 12 to 60 months (1 to 5 years), although some deals such as those for motorhomes or caravans can be longer. The longer the term, the lower the monthly payments, but the more interest you’ll pay over time. 

Example: A £15,000 loan over 3 years at 5% interest will have a higher monthly payment but less total paid than the same loan but taken over 5 years. 

Deposit

The deposit is the upfront payment you make when purchasing a vehicle. A larger deposit reduces the loan amount, reducing the interest you’ll pay and possibly lowering your monthly payments. 

Example: A £5,000 deposit on a £20,000 car reduces your loan amount to £15,000, lowering your monthly payments and overall interest.

Balloon Payment (PCP)

For Personal Contract Purchase (PCP) agreements, a balloon payment of Optional Final Payment (OFP) is a lump sum you can pay at the end of the term if you want to own the vehicle outright. This payment is set at the start of the agreement and is usually based on the vehicles predicted residual value at the end of the term.

Mileage Limits (PCP)

In PCP agreements, your monthly payments are also influenced by the agreed-upon mileage limits. Exceeding these limits can lead to additional charges at the end of the term. 

Example: If you exceed your 10,000 miles per year limit, you might have to pay extra charges per mile over the limit. 

Fees and Charges

Additional fees such as arrangement fees, early repayment charges, and late payment penalties can also affect the total cost of your vehicle finance. These should be clearly outlined in your finance agreement. 


Understanding how vehicle finance is calculated helps you make smarter financial decisions. By knowing the factors that affect your monthly payments and the total cost of your loan, you can choose a finance option that suits your budget and long-term plans.
