This is a guide figure, not financial advice. The exact amount comes from your bank or the relevant authority.
Enter the car price, deposit, interest rate and number of months to see the monthly payment, total interest and what you pay altogether. For a car loan leave the balloon at zero; for a lease, enter the final amount you pay to keep the car. Add fees and monthly insurance from the offer. Use one currency throughout.
How it works
The amount financed is the price minus the deposit. With a monthly rate i (annual rate ÷ 1,200) and n payments, the payment is (P − B/(1+i)n) × i / (1 − (1+i)−n), where B is the balloon left for the end. If payments are made in advance, at the start of each month, the result is divided by (1+i) as well.
Copy the costs straight from the offer: arrangement fees, comprehensive insurance (kasko in Serbia) and any tax on interest. The calculator doesn't work out the APR (EKS, the effective rate Serbian banks must quote), so compare offers on that figure too.
Worked example
A car costs €20,000 and you put down 20%, so €16,000 is financed. Over 60 months at 6%, with payments at the end of each month, the payment is €309.32 before any extras. With the deposit, you pay €22,559.49 in total.
Switch to a lease with a €4,000 balloon and the monthly payment drops, but that €4,000 is still waiting for you at the end.
Questions people ask
Is a lease with a lower monthly payment cheaper?
Not necessarily. The balloon moves part of the debt to the end, and you pay interest on it the whole time. Compare the total, including the final payment, insurance and fees.
What price should I enter?
The full price from the offer, before the deposit comes off. Keep VAT consistent: don't mix a price without VAT with fees that include it.
Where do I put compulsory comprehensive insurance?
Add the average monthly premium under monthly extras. If the insurance is paid once a year, divide it by 12.
Why is the dealer's figure slightly different?
They may use a different interest method, another first payment date, or extra taxes. Here you can switch between paying in advance and in arrears, but the rate stays fixed for the whole term.
