About this calculator
EV charging station revenue depends on session frequency, average energy dispensed per session, and your price per kWh (or per-minute pricing where local law requires it), minus the electricity cost you pay your utility, which is often on a demand-charge structure that penalizes low-utilization stations disproportionately. This calculator takes sessions per day, average kWh per session, price per kWh charged to drivers, wholesale electricity cost per kWh, and a monthly demand charge or network/software fee, to compute gross revenue, electricity cost, and net monthly profit per charger. DC fast chargers see far higher revenue per unit than Level 2 but also carry a much higher equipment and installation cost and higher demand charges from short bursts of high power draw.
Worked example
Using the values the calculator loads with:
Inputs
- Charging sessions per day: 8
- Average kWh dispensed per session: 28
- Price charged per kWh: 0.42 $
- Utility electricity cost per kWh: 0.16 $
- Monthly network/software/demand charge fees: 220 $
Results
- Monthly net profit per charger: $1,550
- Monthly gross revenue: $2,860
- Monthly electricity cost: $1,090
- Monthly kWh dispensed: 6,810
- Annualized net profit: $18,606
What each field means
Inputs
- Charging sessions per day

- Price charged per kWh ($)
- The price charged per kwh used in the calculation, measured in $. Starts at 0.42 $ so you have a working example on load.
- Utility electricity cost per kWh ($)
- The utility electricity cost per kwh used in the calculation, measured in $. Starts at 0.16 $ so you have a working example on load.
- Monthly network/software/demand charge fees ($)
- The monthly network/software/demand charge fees used in the calculation, measured in $. Starts at 220 $ so you have a working example on load.

FAQ
Why do demand charges matter so much for DC fast chargers?
Utilities often bill commercial demand charges based on the single highest 15-minute power draw in the month, and a 150-350 kW fast charger can spike demand dramatically even with low overall utilization, sometimes making the demand charge larger than the energy cost itself at low-traffic sites.
What margin per kWh is realistic?
Public DC fast charging networks commonly price $0.35-$0.55/kWh against wholesale electricity cost of $0.10-$0.20/kWh, giving a gross margin of roughly 50-70% before demand charges and fixed fees — but low utilization sites can see that margin wiped out entirely by demand charges and network fees.
How many sessions per day should I expect at a new site?
Highway corridor DC fast chargers can average 8-15+ sessions per day per stall at a mature, well-trafficked site; workplace or retail Level 2 chargers typically see far fewer paid sessions per day (2-5) since dwell time is longer and pricing per session is usually much lower.
Does charger hardware and installation cost factor into this?
No, this tool is operating profit only. DC fast charger hardware plus installation (including any utility service upgrade) commonly runs $50,000-$150,000+ per stall, so pair this monthly net profit figure with a separate payback calculation against that upfront capital cost.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
