Free car tools and calculators
Work out what your car costs before you pay it: fuel consumption and cost per km, the car loan, and whether a CNG conversion pays off. Every calculator is free and runs on your device; we don't store your numbers.
Each calculator here answers one question car owners in Saudi Arabia and Egypt ask every month: how much fuel does my car use? What does each kilometre cost me? How many instalments are left? Is a CNG conversion worth it? Enter your numbers and the answer appears at once, with the method explained so you know where every figure comes from.

Calculators set up for your country
In Saudi Arabia
The fuel calculator starts with today's 91 or 95 price in riyals, and the loan calculator explains flat-rate profit and the balloon payment the way common Saudi car-finance offers work. Results are in riyals with clear Latin digits.
In Egypt
The fuel calculator knows 80, 92 and 95 in pounds, and the CNG calculator compares petrol and gas for your monthly distance and works out when the conversion pays back, allowing for the share of trips still driven on petrol.

Formulas
The formulas, in short
Fuel consumption
Litres ÷ kilometres × 100 = L/100 km.
Example: 40 litres over 500 km = 8 L/100 km.
Cost per km
Everything the car cost you in a month ÷ the kilometres you drove that month.
Example: 1,500 in costs ÷ 3,000 km = 0.5 per km.
Monthly payment, flat rate
(Car price − down payment) × (1 + yearly rate × years) ÷ months.
Use the calculator to add a balloon payment if there is one.
CNG conversion payback
Conversion cost ÷ monthly saving = months until it pays back.
Example: 30,000 ÷ 2,500 saved a month = 12 months.

FAQ
FAQ
Are the calculators free?
Yes. All of them are free, need no sign-up and run in the browser on a phone or computer.
Do you save the numbers I enter?
No. The maths runs on your device and your numbers never reach us. To keep your fill-ups and costs, log them in the Sayarti+ app.
How do I work out my car's cost per km?
Add up everything the car cost in a month (fuel, service, insurance, instalment, parking) and divide by the kilometres you drove. For fuel alone use the consumption calculator; for several cars use the fleet calculator.
I manage company cars. Which tool fits?
Start with the fleet cost per km calculator and the fleet tracking template. If you want drivers to log from their phones and reminders to reach you, try Sayarti+ Business free for 14 days, no card.
