How the math works
Annual kWh = chargers × sessions × 365 × kWh/session. Revenue = kWh × $/kWh.
6 × 8 × 365 × 30 = 525,600 kWh × $0.48 = $252,288 revenue − $78,840 cost = $173k margin (69%).
How to Use
- Enter number of DC fast chargers.
- Enter kW per charger.
- Enter sessions per charger per day.
- Enter kWh per session.
- Enter revenue per kWh charged.
- Enter utility cost per kWh.

Frequently Asked Questions
DC fast charger economics?
150 kW charger: $45-75k hardware, $50-150k installation (trenching, transformers, panels). 350 kW charger: $80-150k hardware, $100-250k installation. Typical 4-8 charger site: $600k-2M all-in. Revenue: $25-75k/charger/year when at 15-25% utilization. Operating cost: $8-20k/charger/year (utility cost, maintenance, network). Payback: 5-12 years.
Utilization rates?
New site (year 1): 3-8% utilization — slow ramp. Year 2-3: 10-15%. Year 4-5: 15-25%. Mature site: 25-40%. Top-performing Tesla Supercharger: 40-60% peak weekends. Utilization = sessions per day × avg session time ÷ 24 hours × 365. 8 sessions/day × 35 min ÷ (24 × 60) = 19% utilization. Ramp driven by EV adoption curve + station location quality.
Revenue per kWh?
Tesla Supercharger: $0.35-0.50/kWh (non-Tesla). Electrify America: $0.48-0.68/kWh. EVgo, ChargePoint: $0.40-0.65/kWh. Pricing by session + idle fees common. Free charging programs (auto OEM, hotel, destination) subsidize cost. Price increased 40-80% 2020-2024 as electricity costs rose. Utility demand charges add $0.10-0.25/kWh equivalent at low utilization.
Site selection?
Highway corridor: 25-75 miles between stations for interstate travel. Destination: resort, hotel, retail (drive-time 30+ min). QSR/C-store co-location: drive amenity usage (spend while charging). Demographics: affluent EV-adopter zip codes. Grid capacity: 750+ kW service, upgrade $100-500k if needed. Site footprint: 0.25-1 acre for 4-8 chargers + buffering.
