Car Finance Calculator (Instalment, Balloon & NCA Fees)

What is vehicle finance in South Africa?

Vehicle finance is a loan or instalment sale that lets you buy a car, motorbike, boat or truck and pay for it over time. In most cases the lender keeps ownership until the last payment is made. Because it is a credit agreement, it is regulated by the National Credit Act 34 of 2005 (NCA) and its Regulations. The Act limits the interest rate and the fees a credit provider may charge, and requires a clear quotation before you sign.

How the calculation works

The calculator starts with the vehicle price and subtracts your cash deposit and the net trade-in value. If the initiation fee is financed, it is added back to the amount you borrow. This gives the total amount financed.

The monthly interest rate is the quoted annual rate divided by twelve. The instalment is the level monthly payment that clears the amount financed over the chosen number of months. If you choose a balloon, the calculator first discounts the balloon back to today and then spreads only the remaining capital across the instalments. A higher balloon therefore means a lower instalment, but you pay interest on the balloon for the whole term.

On top of the instalment, the credit provider charges a monthly service fee. The total monthly payment shown in large type is the instalment plus this fee.

NCA fees to watch

• Initiation fee: a once-off fee for setting up the loan. The Regulations cap it using a sliding scale based on the size of the agreement. It may be paid in cash or added to the loan.
• Monthly service fee: a fixed monthly account fee, also capped by the Regulations.
• Interest: the maximum rate depends on the type of agreement and is linked to the repo rate. Lenders usually price vehicle finance as prime plus or minus a margin based on your credit profile.

All of these form part of the cost of credit, so the calculator adds interest, the initiation fee and every service fee together.

Worked example

Suppose a car costs R300,000 and you pay a R30,000 deposit with no trade-in. The initiation fee is R1,207.50 and is financed, so you borrow R271,207.50. Over 72 months at 12% a year (1% a month) with no balloon, the instalment is roughly R5,300. Adding a R69 service fee gives a monthly payment of about R5,370. Over the term you repay approximately R381,700 in instalments, so the interest is about R110,500. Adding the initiation fee and the service fees (about R4,970) gives a total cost of credit of roughly R116,700.

Common situations

• Balloon or residual payment: useful if you want a lower instalment, but you must have the money, refinance or sell the vehicle when the balloon falls due.
• No deposit: you can finance the full price, but the instalment and total interest are higher, and some lenders will charge a higher rate.
• Trade-in: only the equity counts. If you still owe money on your old car, subtract the settlement figure before entering the trade-in value.
• Shorter term: a higher instalment but much less interest overall.
• Motorbikes, boats and trucks: the same mechanics apply, though lenders may use different terms, deposits and balloon limits.

Before you sign

Compare quotations from several lenders and check the interest rate, the fees, the balloon and whether the quote includes insurance or add-ons. Do not forget insurance, which lenders normally require, and the licence and registration costs.

Which document to prepare next

Once you have settled on the numbers, you will need paperwork. If you are buying from a private seller or a dealer, a Sale of Goods Agreement records the vehicle, the price, delivery and the transfer of risk and title. If the instalments are owed to a person or business other than a bank, a Payment Agreement sets out the amount, the number of payments, the interest and what happens on default. The figures from this calculator (price, amount financed, term, rate and monthly payment) can be used to fill in these documents.
