Calculation method
How E85 profitability is calculated
The calculator compares yearly SP95/E10 cost with yearly E85 cost after overconsumption. If savings are positive, the conversion kit cost is divided by monthly savings.
yearly savings = petrol cost - E85 cost ; payback = kit cost ÷ (yearly savings ÷ 12)
Example
E85 profitability example
With 15,000 km/year, 7.2 L/100 km on petrol at 1.86 EUR/L, +25% E85 consumption at 0.92 EUR/L and a 900 EUR kit.
Estimated savings are about 767 EUR/year and the kit pays back in about 14.1 months.

E85 savings
The calculation compares yearly SP95/E10 cost with yearly E85 cost including overconsumption.
Conversion kit
Kit cost can be included to estimate how many months are needed to pay it back.
Clear threshold
The output shows whether E85 really saves money and when it starts paying off.
E85 is often cheaper per liter, but it usually increases consumption. An E85 profitability calculator must therefore compare the real yearly cost, not only the displayed pump price difference.
