Petrol / Fuel Cost Calculator ☆ Save

The annual figure is the useful one

Fuel gets paid for in small, forgettable amounts, which is exactly why the yearly total surprises people — it is frequently larger than bills the household worries about far more.

Once you have the number, it becomes useful in three concrete ways.

1. It changes which car you should buy

Consumption over several years can exceed the price difference between two vehicles. Compare on total cost of ownership, not sticker price:

• Model your genuine monthly distance — commute, school run, weekends — rather than an optimistic estimate;
• Add insurance, licensing, servicing and tyres;
• Add finance costs from the vehicle finance calculator;
• Then compare the two vehicles.

A cheaper car that drinks fuel is regularly the more expensive choice over five years.

2. It prices where you live

This calculation is almost never run before signing a lease or an offer to purchase, and it should be. Cheaper housing further out is often not cheaper once you add fuel — before you even value the hours spent travelling.

Work out the monthly fuel cost of each commute and add it to the rent or loan instalment. A saving of SDG 2,000 in rent that costs SDG 1,500 more in fuel is a SDG 500 saving for a substantially longer day. Test the housing side in the rent vs buy calculator.

3. It makes a large budget line visible

Transport is among the biggest and least examined household costs. With the annual figure in front of you, the levers become obvious — and several are painless:

• Combining trips, which is free;
• Sharing transport for a regular journey, including the school run;
• Keeping the vehicle serviced and tyres correctly inflated — consumption worsens measurably as maintenance slips;
• Driving style — hard acceleration and sustained high speeds cost real money over a year.

Whatever you free up, move it deliberately — into an emergency fund via the savings calculator, or against expensive debt using the debt payoff planner. Money merely "saved" without being moved gets absorbed.

If you run a business or claim travel

If you deliver, travel to customers, or use a vehicle for work, fuel is a direct cost that belongs in your pricing — and it is one of the overheads most commonly left out, which is why some jobs feel busy and unprofitable. See the business funding calculator for the wider cost picture.

Where your tax authority allows a travel deduction, it will almost certainly require a logbook recording odometer readings and business distance. Start it at the beginning of the tax year rather than reconstructing it later — unsupported claims are among the most commonly rejected.

Frequently asked questions

What fuel price should I use?

The price you actually paid most recently. We deliberately do not publish a pump price — it changes regularly, and a stale figure would distort your whole budget.

How do I find my vehicle's real consumption?

Fill the tank, note the odometer, drive normally, then refill and divide the litres used by the distance travelled. Two or three cycles give a realistic average — manufacturer figures are usually optimistic against real conditions.

Is it worth changing cars to save fuel?

Only if the saving exceeds the cost of changing, including transaction costs and any new finance. Run both vehicles' total cost of ownership — the answer is often no.

Should I include a generator?

Yes, if you are working out total household energy costs — and that figure is exactly what you need to judge whether alternative power would pay for itself.

Does driving less really make a difference?

Over a year, materially. Combining trips and sharing a regular journey are the two changes that cost nothing and show up immediately.

Fuel prices change regularly and are deliberately not published here — use your own most recent price. Tax treatment of travel claims varies by market. General information, not financial advice.
