Four passengers, four splits - a complete reference for sharing driving costs
A 300 km highway trip at 7 L/100 km and $1.50/L costs $31.50 in fuel. Driving solo, that is your bill. With 3 riders, each pays $10.50. With 5, just $6.30. The math is simple - but people still argue about it at gas stations. This calculator settles it in one click.
Quick reference - cost per person by distance and riders
Assumptions: 7 L/100 km, $1.50/L, no tolls.
| Distance | Solo | 2 riders | 3 riders | 4 riders | 5 riders |
|---|---|---|---|---|---|
| 50 km | $5.25 | $2.63 | $1.75 | $1.31 | $1.05 |
| 100 km | $10.50 | $5.25 | $3.50 | $2.63 | $2.10 |
| 200 km | $21.00 | $10.50 | $7.00 | $5.25 | $4.20 |
| 500 km | $52.50 | $26.25 | $17.50 | $13.13 | $10.50 |
| 1,000 km | $105.00 | $52.50 | $35.00 | $26.25 | $21.00 |
Savings classification - how much carpooling saves annually
How the calculation works
- Fuel used = distance (km) x consumption (L/100 km) / 100
- Fuel cost = fuel used (L) x price per liter ($)
- Total cost = fuel cost + tolls and fees
- Cost per person = total cost / number of riders
Practical examples
Carpooling vs other transport - cost per 300 km trip
| Transport mode | Cost per person | Travel time | Flexibility |
|---|---|---|---|
| Solo driving | $31.50 | 3-4 h | Door to door |
| Carpooling (3 riders) | $10.50 | 3-4 h | Door to door |
| Bus (intercity) | $15-30 | 4-5 h | Fixed schedule |
| Train | $25-50 | 2.5-4 h | Fixed schedule |
| Budget airline | $40-120 | 1 h + 2 h airport | Fixed, limited routes |
With 3 riders, carpooling beats the bus on both price and convenience. With 4-5 riders, it undercuts even the cheapest intercity coaches. The only advantage of a train or bus is that nobody has to drive - everyone can sleep or work.
Extra weight and consumption - what a full car costs
Every additional 100 kg of passenger and luggage weight increases fuel consumption by roughly 0.3-0.7 L/100 km depending on engine size and driving style. A car with 4 adults and weekend bags carries about 300 kg more than a solo driver - expect 1-2 L/100 km higher consumption. The calculator uses the figure you enter, so check your trip computer after a loaded trip for the most accurate split.
| Scenario | Extra weight | Consumption increase | Extra fuel cost per 300 km |
|---|---|---|---|
| 1 passenger (75 kg) | 75 kg | +0.3 L/100 km | $1.35 |
| 3 passengers + bags | 250 kg | +1.0 L/100 km | $4.50 |
| 4 passengers + luggage | 350 kg | +1.5 L/100 km | $6.75 |
Even with the extra fuel from a loaded car, the per-person cost drops sharply. A solo 300 km trip at 7 L/100 km costs $31.50. The same trip with 4 people at 8.5 L/100 km costs $38.25 total - just $9.56 each.
