EV charging station economics: installation 5-30k per charger (rapid: 30-80k), energy cost 0.15-0.25/kWh wholesale, charge price 0.40-0.80/kWh retail. Margin per kWh: 0.20-0.50. With 4-10 sessions/day per charger at 30 kWh average, monthly revenue 1,000-4,500 per charger.

10 chargers × 15k install = 150k. 6 sessions/day × 30 kWh × 0.50 charge = 90/day per charger × 10 = 900/day. Energy cost: 0.20/kWh × 1,800 kWh/day = 360. Daily profit 540, monthly 16,200. Payback 9.3 months. Strong economics driven by increasing EV adoption.

Location is everything: motorway services and retail parks with high footfall see 8-15 sessions/day. Residential areas 2-4 sessions/day. Workplace charging 4-8 during business hours. Site selection determines whether a charger makes money or sits idle.

Run it with sensible defaults

Using number of chargers of 10, install cost per charger of 15,000, energy cost per kwh of 0.2, charge price per kwh of 0.5, the calculation works out to 16,200.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Number of Chargers, Install Cost per Charger, Energy Cost per kWh, Charge Price per kWh, and Sessions per Charger Daily — do not pull with equal force. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

How the math works

Revenue = chargers × sessions × kWh × price × 30 days. Energy = same at energy cost. Profit = revenue - energy. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Beyond the number

Carbon, health, and local air quality don't show up on the calculator but often drive the decision. The financial figure is a lower bound on the value; the rest is whatever you'd pay for the non-financial benefits.

What this doesn't capture

Carbon reduction, health benefits, and local air quality have real value the financial figure doesn't price. The calculation gives the money side honestly; for the full picture, note the non-financial benefits alongside.

Example Scenario

10 × 6/day × 30kWh × (£0.5 £ - £0.2 £) = $16,200.00.

Inputs

Number of Chargers:10
Install Cost per Charger:15,000 £
Energy Cost per kWh:0.2 £
Charge Price per kWh:0.5 £
Sessions per Charger Daily:6
Avg kWh per Session:30
Expected Result$16,200.00

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

Sources & Methodology

Methodology

Revenue = chargers × sessions × kWh × price × 30 days. Energy = same at energy cost. Profit = revenue - energy.

Frequently Asked Questions

Rapid vs slow charger?
Slow (7kW): 5-10k install, 3-4 hour charge, 0.35-0.50/kWh. Rapid (50kW): 20-40k, 30-45 min, 0.50-0.70/kWh. Ultra-rapid (150kW+): 50-80k, 15-30 min, 0.60-0.80/kWh. Higher power = higher revenue per session but higher install cost.
Government grants?
OZEV Workplace Charging Scheme: up to 350 per socket (max 40). On-street: up to 60% of install cost. Check current schemes at gov.uk - grants change frequently but consistently available for commercial installations.
Energy contract matters?
Wholesale energy at 0.15-0.20/kWh vs domestic at 0.30+/kWh makes big difference. Negotiate commercial energy contracts. Solar/battery pairing can reduce effective energy cost to 0.05-0.10/kWh for daytime charging.
Future-proofing?
Install higher-power cabling than current chargers need. A 22kW AC today with 100kW cabling underneath can upgrade later without re-trenching. Trenching is 50-70% of install cost - do it once for maximum future capacity.
