EV charging contribution planner
Explore how energy sales and operating costs affect monthly contribution. Use your own figures and one consistent currency. These calculations are scenarios, not forecasts.
Start with your numbers.
Complete all six inputs, entering zero where appropriate. No market assumptions are supplied.
What the calculation includes
Monthly contribution = energy sold × (selling price − electricity cost − other variable cost per kWh) − fixed monthly costs. Simple payback = initial investment ÷ positive monthly contribution.
Include applicable demand charges, maintenance and connection costs in the appropriate inputs. Taxes, financing, depreciation, replacement costs, seasonal changes and additional store sales are not calculated separately. Simple payback ignores the time value of money. A positive result does not establish that an investment is suitable.
