Fuel Cost Calculator for Fleets
What does fuel cost your fleet per year? Breakdown by diesel, gasoline, HVO and electricity — with cost per vehicle, per kilometre, plus a sensitivity analysis for ±10 ct/L price swings.
Your annual fuel spend
Breakdown by fuel type
| Fuel | Volume / year | Cost / year | Cost per km |
|---|---|---|---|
| Diesel | — | — | — |
| Gasoline | — | — | — |
| HVO 100 | — | — | — |
| Electric (BEV) | — | — | — |
Sensitivity analysis
What if the fuel price rises or falls by 10 ct/L? (BEV: ±5 ct/kWh)
| Scenario | Annual cost | Change |
|---|---|---|
| Fuel price −10 ct/L | — | — |
| Current fuel price | — | — |
| Fuel price +10 ct/L | — | — |
Modelling only. Real fuel cost depends on driving style, when you refuel, regional price levels, and consumption variance.
How we calculate
Fleet fuel cost is a simple multiplication — but the breakdown per fuel and per kilometre is what reveals the biggest lever: driving style (consumption), where you refuel (branded vs. discount stations), or fleet composition (switching to EV or HVO).
The formula per fuel
Vehicles × avg km/year × consumption / 100 × price = annual cost. Cost per km = annual cost / (vehicles × km). For EVs replace litres with kWh — otherwise identical.
Why a sensitivity analysis?
Fuel prices fluctuate seasonally by 10–15 ct/L; geopolitical shocks can move them 30 ct/L or more (see 2022). A sensitivity table instantly shows how hard a +10 ct jump would hit. For large fleets these are five-digit annual amounts — an argument for hedging or accelerated transition to less volatile energy.
Where DKV InstantFuel helps
DKV InstantFuel logs every fueling event with date, station, litres and price in the dashboard — you spot regional price trends, branded-station premiums and driver-specific consumption outliers in real time. Instead of sorting receipts monthly, you see the data live.
