Formula
What this calculator does
Estimates your Saudi auto finance monthly installment, total cost, and DBR-based eligibility. Handles: down payment (typical 15-30%), trade-in (reduces loan amount), balloon payment option (popular for premium vehicles), SAMA's 33% DBR cap, and 60-month tenure cap. Applies standard reducing-balance amortization - the calculation method used by all Saudi banks for both conventional and Islamic (Murabaha) auto finance products.
SAMA limits for auto finance
SAMA caps Saudi auto finance with two binding limits: (1) Debt-burden ratio (DBR) ≤ 33% - the most restrictive cap among Saudi consumer finance categories. Mortgage DBR cap is 65%, personal finance 65% - but auto is tighter because vehicles depreciate fast. (2) Maximum tenure 60 months (5 years) - shorter than mortgages (30 yr) and personal finance (5-7 yr for some), again because of depreciation. Both apply regardless of bank or product type. Banks may apply STRICTER internal limits but cannot exceed SAMA caps. The 33% DBR includes mortgage installments, personal finance, credit card minimums (typically 5% of statement balance), and the new auto installment.
Balloon payment (الدفعة الأخيرة) - pros and cons
A balloon payment is a large lump sum due at the end of your loan tenure (typically 20-40% of the loan amount). Popular for premium vehicles (Mercedes, Lexus, BMW). Pros: significantly lower monthly installments. A 200K SAR loan over 60 months at 5% APR has 3,775 SAR monthly with no balloon - but with 30% balloon (60K SAR), monthly drops to 2,825 SAR (25% lower). Cons: You face a 60K SAR bill at month 60. Options at that point: pay cash (you must have it saved), refinance the balloon as a new loan (extends total cost), or sell the car to settle. The 'sell to settle' option only works if the car's residual value covers the balloon - depreciation can leave you upside down.
Down payment strategy
Higher down payment reduces: (1) Loan amount, so monthly installment drops proportionally. (2) Total interest paid - significantly. On a 150K SAR vehicle at 5% APR over 60 months, 10% down (135K loan) results in 30K total interest. 30% down (105K loan) results in 23K interest - a 7K savings just from the down payment difference. (3) Risk of being upside-down (owing more than the car is worth). New cars depreciate ~20-25% in year 1; a 10% down payment puts you immediately upside-down. A 20-25% down payment gives you a cushion against depreciation. Saudi banks typically require minimum 15-20% down; some go to 10% for premium employer profiles. Don't go lower than 20% if you can help it.
Buy with finance vs. lease (إيجار تشغيلي)
Finance: you own the car at the end (or after balloon). Total cost = down + installments + balloon. Lease (operating lease, العقد الإيجاري): no ownership, you pay monthly to use; at the end you return or buy at residual price. Lease is structurally similar to a finance with 100% balloon. Use the calculator with balloon at 50-60% to roughly approximate a lease. Lease pros: lower monthly, includes insurance/maintenance, no resale hassle. Lease cons: never build equity, mileage limits, higher total cost over multiple vehicles in your lifetime. For Saudi salaried employees who upgrade cars every 3-4 years anyway, lease often makes financial sense; for those who keep cars 7+ years, finance is better.
