How to Use This Calculator

Trip Cost Tab

Enter your trip distance in kilometres, your vehicle's fuel efficiency (litres per 100km), and the current petrol pump price. Use the distance presets for quick estimates. The calculator shows total litres used and total naira cost instantly.

Monthly Cost Tab

Enter your one-way commute distance and the number of working days per month (default 22). The calculator doubles your commute distance for the round trip and multiplies by working days to give your monthly and annual fuel spend.

The Formula

Trip Cost: Litres Used = Distance (km) × Fuel Efficiency (L/100km) ÷ 100 Fuel Cost = Litres Used × Pump Price (₦/L) Monthly Cost: Daily Distance = One-Way Commute × 2 (round trip) Monthly Distance = Daily Distance × Working Days Monthly Fuel Cost = Monthly Distance × Efficiency ÷ 100 × Pump Price Annual Fuel Cost = Monthly Fuel Cost × 12

Fuel efficiency varies significantly by vehicle type and Lagos traffic conditions. City driving in stop-and-go Lagos traffic typically burns 20–40% more fuel than highway driving.

Example

Emeka commutes from Ajah to Victoria Island daily

One-Way Distance35 km
Fuel Efficiency12 L/100km
Petrol Price₦900/L
Working Days22 days
Daily Round Trip70 km
Monthly Distance1,540 km
Monthly Fuel Used184.8 litres
Monthly Fuel Cost≈ ₦166,320
Annual Fuel Cost≈ ₦1,995,840

Emeka spends nearly ₦2M per year just on fuel for his commute. Moving closer to work or using public transport even 2 days a week could save over ₦360,000 annually.

Nigerian Fuel Price Context

Nigeria's petrol prices have changed dramatically since subsidy removal in 2023:

Typical fuel efficiency by vehicle type in Nigerian conditions:

Lagos traffic significantly reduces fuel efficiency. During peak hours, actual consumption can be 25–40% higher than stated figures. Factor in at least 15% buffer for real-world driving conditions.

FAQ

As of early 2026, NNPCL pump price is approximately ₦900/litre for petrol (PMS). Independent marketers may charge slightly higher or lower depending on their location and supply costs. Prices vary by state — Lagos and Abuja tend to have more competitive pricing than remote northern or southern states. Always update the pump price in the calculator to reflect your local current price.
Fill your tank completely, reset your trip meter, then drive normally until you refuel. When you refuel, note how many litres you put in and how many kilometres you drove. Divide litres by kilometres × 100 to get L/100km. Most modern cars also display this in the instrument cluster. For Nigerian traffic, real-world consumption is typically 15–30% higher than the manufacturer's stated figure.
For most Lagos commutes, public transport is significantly cheaper than driving once you factor in fuel, parking, vehicle wear, and maintenance. A typical Lagos commute that costs ₦150K–₦200K/month in fuel and wear costs ₦15K–₦40K/month by BRT and bus. The trade-off is time — public transport often takes 2–3x longer in heavy traffic.
