Fuel costs add up fast – especially if your team travels for client visits, deliveries, site inspections, or sales routes. This South African fuel cost calculator helps you estimate litres used and total trip cost, add tolls and parking, and project a monthly travel budget for your business.
It also lets you compare your trip cost to a per-kilometre reimbursement rate, so you can sense-check whether your policy still matches real-world costs.
Fuel Cost Calculator (SA)
Estimate fuel litres and cost per trip and per month. Add tolls/parking and compare against a per-km reimbursement rate.
Trip inputs

FAQ: Fuel cost calculator
1) Should I use L/100km or km/L?
Use whichever you know. Many SA vehicle specs use L/100km, while some fleet teams prefer km/L for quick comparisons.
2) What fuel price should I use in South Africa?
Use the current pump price you’re paying in your area. SA pump prices are updated regularly (often monthly), so update the input when prices change.
3) Does this include maintenance, tyres, and insurance?
No — this is a fuel-focused calculator with optional tolls/parking. For full cost-per-km, you’d typically add servicing, tyres, depreciation, insurance, and finance/lease costs.
4) What reimbursement rate per km should I use?
Use your company policy. Many businesses also reference SARS “rates per kilometre” as a benchmark (but your policy may differ).
5) Can I use this for delivery pricing?
Yes. A practical approach is: (cost per km × route km) + time/labour + margin. This tool gives you a clean cost-per-km starting point.
