Guide / 02
Quick guide
- Enter distance per trip in kilometers, observed efficiency in km/L, and price per liter.
- If repeating the route, use a trip count that is consistent about whether distance is one-way or round-trip.
- Review liters and cost, then calibrate the estimate against recent dashboard efficiency or refueling records.
Check
Validate the result
At 100 km, 10 km/L, 1,500 per liter, and one trip, the result should be 10 L and 15,000 in the entered currency.
Limits
Know the limits
The formula assumes km, km/L, and a per-liter price. Tolls, parking, idling, detours, load, and weather-related efficiency changes are excluded, and the currency is whatever the price input represents.

FAQ
Frequently asked
If 320 km already includes the return journey, should trips be set to two?
No. Use one when 320 km is the complete round trip. Use two only when the distance field contains the 160 km one-way segment.
