What remains
after the shift.
Three routes, unchanged revenue. A change in fuel cost shows how much remains for other costs.
One fictional shift. All amounts in CZK, excluding VAT.
- Revenue
- 12,350 CZK
- Wages and fuel
- 9,660 CZK
- Remaining contribution
- 2,690 CZK
Contribution is not profit.
Only fuel changes. Revenue, wages, distance and stops remain fixed.
| Route | Revenue | Wages | Fuel | Contribution |
|---|---|---|---|---|
| Route A112 km · 29 stops | 4,200 | 2,180 | 1,050 | 970 |
| Route B83 km · 17 stops | 3,350 | 1,760 | 790 | 800 |
| Route C135 km · 34 stops | 4,800 | 2,610 | 1,270 | 920 |
At the original costs, CZK 2,690 remains after wages and fuel. Other costs still have to be covered from this amount.
Contribution = revenue − wages − fuel. Fuel is rounded to whole CZK for each route; amounts ending in CZK 0.50 round upwards. The total follows the displayed rows.
What else must
the remainder cover?
The model excludes overhead, vehicle depreciation or leasing, servicing and tyres, insurance, tolls, parking, financing, taxes and other direct costs. It is not a complete operating-cost calculation.
At twice the fuel cost, the total is −CZK 420 before those other costs. Before changing a price, route or carrier, fill the cost gaps and check the operating constraints.
What the example shows
An original B&F presentation of a fictional three-route model. It is not a client engagement, an achieved saving or employer data. The example explains the calculation and its boundaries; it does not establish the viability of a real route.
