The petrol calculation multiplies your distance by your consumption rate to find litres or gallons used, then multiplies by your local fuel price. The formula adapts to your chosen units: for L/100km, fuel = distance × consumption ÷ 100; for mpg, fuel = distance ÷ mpg. All prices stay in whatever currency you enter — the calculator never converts currencies.
The EV calculator finds the kWh needed for your trip (distance × kWh/100km ÷ 100) and applies your home and public charging tariffs separately. Two comparisons are shown: home charging vs petrol, and fast/public charging vs petrol. Home charging at off-peak household rates is almost always cheaper than petrol; fast charging at motorway tariffs can cost as much as or more than petrol — the calculator shows this honestly for both scenarios rather than reporting only the favourable case.
There are no live fuel-price feeds. Prices vary by country, supplier, and day — entering your own figures gives a more accurate result than any default could. Danish defaults are pre-filled as an example (14.50 kr/L petrol; 3.00 kr/kWh home electricity; 5.50 kr/kWh public charging). Any option left blank is silently omitted from the comparison.
