A small price change per litre can look insignificant, but regular commuting multiplies it across every refill. Measuring the actual monthly impact makes budget adjustments easier.
1Find monthly fuel consumption
Divide monthly distance by real-world mileage. This gives the litres used before considering the price.
2Measure the price difference
Subtract the old price from the new price. Multiply this difference by monthly litres.
3Annualise the result
A modest monthly increase becomes more meaningful across twelve months.
4Test mileage improvement
Better tyre pressure, smoother driving and maintenance may offset part of a price increase.
5Review transport alternatives
Car-pooling, public transport, trip combining and remote work can reduce kilometres where practical.
Practical checklist
- Track monthly distance
- Use real mileage
- Calculate monthly litres
- Compare annual impact
- Review avoidable trips
