Cars and travel
Real fuel economy, what a trip costs, cost per mile and splitting the bill between everyone in the car.
Fuel economy
4 tools- Real fuel economy calculator Fuel put in and distance covered. That is all it takes to know what your car really does, rather than what the trip computer claims.
- Cost per unit of distance of your car Fuel is the part you notice and the smallest part of the bill. This adds the ones you do not: insurance, tax, servicing and, above all, depreciation.
- Compare the fuel cost of two cars Two cars, two consumption figures, two fuel prices. What the difference actually adds up to over the years you will keep it.
- Electric car charging cost What a charge costs and how far it takes you. Including the energy you pay for that never reaches the battery, which nobody mentions.
Cost of a trip
2 tools- What a trip costs in fuel Distance, consumption and fuel price. What the trip really costs, tolls included, and whether the train was cheaper after all.
- Split the cost of a trip The awkward conversation, settled with a number. Fuel, tolls and extras split between everyone, or everyone except the driver.
