A flat rate is charged on the full amount for the whole term, a reducing rate only on what's left, so 3.5% flat over 5 years costs about the same as 6.5% reducing. Don't compare offers by the headline rate; compare the annual percentage rate (APR) and the total you'll pay, including fees, balloon and insurance.
Most car finance offers in Saudi Arabia are murabaha: the financier buys the car and sells it to you at a higher price paid in instalments, and the difference is the “profit”. In Egypt it's usually called “interest”. Either way, the big number in the advert is usually a flat yearly rate, and it looks much smaller than it really is.
The difference in one line: a flat rate charges profit on the full amount every year even after you've paid half of it back; a reducing rate charges only on what you still owe. The numbers, and a converter between the two, are on the car loan calculator page.
The annual percentage rate (APR) is the true yearly cost of the finance, calculated on a reducing basis and including admin fees. In Saudi Arabia, the central bank (SAMA) issued rules in 2023 that standardise how this rate is calculated for consumer finance, and they apply to every finance provider in retail lending: the rate is worked out with SAMA's method and calculator in advertising, at the offer stage, in the finance contract and in periodic statements. So ask for the APR in writing in the offer before comparing anything.
In Egypt, ask the bank or company for the “equivalent reducing rate” or effective yearly rate, and ask for the full repayment schedule. If you're only given the flat rate, convert it yourself in the calculator.
A SAR 120,000 car, SAR 12,000 down, SAR 108,000 financed over 60 months. In all three, comprehensive insurance is not in the payment (you pay it yearly), so the comparison is fair. The numbers are examples, not real offers.
| Offer A | Offer B | Offer C | |
|---|---|---|---|
| Headline rate | flat | 2.9% ثابتة / flat + دفعة أخيرة 30% / 30% balloon | reducing |
| Admin fee | 1,080 | 1,000 | 0 |
| Monthly payment | 2,115 | 1,461 | 2,113 |
| Balloon (month 60) | 0 | 36,000 | 0 |
| Total after the down payment | 127,980 | 124,660 | 126,789 |
| Approx. APR | ≈ 7.0% | ≈ 4.5% | 6.5% |
A: profit = 108,000 × 3.5% × 5 = 18,900; payment = 126,900 ÷ 60. B: profit = 108,000 × 2.9% × 5 = 15,660; payment = (108,000 + 15,660 − 36,000) ÷ 60. C: reducing payment at 6.5% a year. APR worked out from the net amount after fees against the payments and balloon.

Tip: A bigger down payment cuts the financed amount and so all the profit on it. If you have spare cash, weigh paying it upfront against keeping it for emergencies and running costs.
Many car instalment offers in Egypt state the interest as flat over the loan years. Example: EGP 400,000 financed over 36 months at 15% flat: interest = 400,000 × 15% × 3 = 180,000; payment = 580,000 ÷ 36 ≈ EGP 16,111 a month. That's roughly 26% on a reducing basis. So “15%” here costs more than, say, a 22% reducing bank loan. The numbers are an illustration, not market rates; ask the bank for the full repayment schedule and work out the reducing rate from it.
Sayarti+ has a free car financing section: enter the monthly payment, the amount still owed and the due day, and it shows how many payments are left, when the car will be yours, and whether this month's payment is done, with a reminder three days before. Each payment is logged as a car expense, so it counts in your cost per km and reports.
Sayarti+ doesn't offer finance or recommend any lender.
On a flat rate: profit = amount financed × rate × years. To compare, use the APR, which charges only on what's owed and includes fees.
Flat is charged on the full amount for the whole term, reducing on what's left. At the same headline number, flat always costs more.
The true yearly cost of finance on a reducing basis, including fees. In Saudi Arabia it must be stated in the offer, so ask for it in writing.
It lowers the monthly payment and may lower the total, but it's a big sum due at the end. Only choose it with a clear plan to pay it.
Many offers state it flat. Ask for the reducing equivalent and the schedule, or convert it in the loan calculator before comparing.
