How you price charging affects four things at once: utilization, revenue, user satisfaction, and, in some states, legal compliance. A rate that is too high empties your chargers; a rate that is too low leaves money on the table or, worse, loses money on every session. This article walks through the pricing structures available, the cost floor you have to clear, and the legal constraint that decides which structures you can even use.
Start with your cost floor
Before choosing a pricing model, know what a session actually costs you to deliver. Three components matter:
- Electricity. Commercial electricity averages around $0.14/kWh nationally (as of Q2 2026), but your number is what matters, and it can be much higher in California and the Northeast. If you are on a commercial rate with demand charges, your effective cost per kWh during a peak event can be several times the energy rate alone.
- Platform and payment fees. Network software runs roughly $300–$475 per port per year (as of Q2 2026; ChargePoint's published per-port cloud subscriptions land in this band). Payment processing adds a per-transaction cost; some networks now also charge drivers a per-session service fee on top of whatever you set.
- Demand charges. Several chargers ramping up at once can spike your billed peak kW for the month. Load management software smooths this, but the exposure is real and belongs in your cost model.
If you do not know your electricity cost per kWh, get it off your utility bill before setting a single rate. Everything below assumes you have that number.
Pricing structures
Per kilowatt-hour (kWh)
You charge for energy delivered, like a gas pump priced per gallon. This is the structure drivers understand most easily and the one most public networks are moving toward.
Typical range (as of Q2 2026): $0.20–$0.45/kWh for Level 2; $0.30–$0.60/kWh and up for DC fast charging, with premium DCFC sites higher.
| Pros | Cons |
|---|
| Transparent; users pay for what they consume | Not legal everywhere (see below) |
| Easy to compare against home electricity rates | Requires revenue-grade, certifiable metering |
| Cost tracks the value delivered | Metering must pass your state's weights-and-measures rules |
Per minute
You charge for time connected, which sidesteps the electricity-resale question because you are selling parking time, not energy.
Typical range (as of Q2 2026): $0.05–$0.20/minute for Level 2; higher tiers for DCFC, often split by charging speed.
| Pros | Cons |
|---|
| Legally straightforward in nearly every state | Less transparent; drivers cannot predict the bill |
| Naturally discourages overstaying | A faster-charging car pays less per mile added |
| Simple to implement | Harder for budget-conscious users to estimate |
The per-minute method has a known fairness problem: a vehicle that accepts 11 kW pays the same per minute as one that accepts 7 kW but gets far more energy. Some networks address this by tiering per-minute rates by power level.
Flat session fee
A fixed price per session regardless of energy or duration.
Typical range (as of Q2 2026): $2–$10 per Level 2 session; $10–$25 for DCFC.
Flat fees are simple and give predictable revenue per session, but they are unfair across session lengths and give no signal to move the car once charging finishes. They work best where dwell time is naturally consistent (for example, a movie theater or a gym where everyone stays a similar length of time).
Free (amenity model)
You absorb the electricity cost the way you absorb the cost of free Wi-Fi. There is no billing infrastructure and no payment friction, which maximizes adoption and supports a tenant- or customer-attraction goal. The tradeoffs are that you carry the full energy cost, you get no revenue offset, and you invite charger squatting, where a finished vehicle sits in the spot all day.
Free with idle fees is the common middle path: charging is free while energy is flowing, then an idle fee applies once the session completes but the car stays plugged in. This keeps the amenity feel while protecting turnover.
The legal constraint: who is allowed to sell by the kWh
This is the part most property owners do not see coming. In some states, selling electricity by the kilowatt-hour has historically been treated as an activity reserved for regulated utilities. That logic, applied literally, would make per-kWh EV charging by a private property owner a regulated utility act.
Two things have changed the picture:
- Most states have carved EV charging out of utility-style regulation, either by statute or by public utility commission ruling, so that a charging host selling per kWh is not treated as a utility. The clear national trend is toward allowing per-kWh billing.
- NIST Handbook 44 sets the metrology standard for selling electricity as a vehicle fuel. Its electric-vehicle fueling code moved from a tentative to a permanent code effective January 1, 2023. Handbook 44 is not itself federal law; each state's weights-and-measures office decides whether and how to adopt and enforce it. Where it is enforced, per-kWh dispensers must use certified, accuracy-tested meters.
The practical takeaways:
- Per-minute and flat-session pricing are safe almost everywhere. They do not involve selling energy by measured quantity, so the utility-resale question does not arise.
- Per-kWh pricing is allowed in most states but not all, and where it is allowed it may require certified metering. A few jurisdictions still effectively push operators to per-minute billing.
- Verify your own state before committing to per-kWh. Check with your state energy office or public utility commission, and confirm metering requirements with your state's weights-and-measures division. Do not rely on what a charger vendor tells you; vendors sell nationally and the rules are local.
If per-kWh is permitted where you operate and your hardware supports certified metering, it is usually the best default for paid charging because drivers trust it. If it is not permitted, per-minute (tiered by power level if you can) is the standard fallback.

Setting the right rate
Cover the cost floor, then add margin. Suppose your electricity costs $0.14/kWh. A 7.2 kW Level 2 charger then costs you about $1.00/hour in energy. Pricing at $0.30/kWh leaves roughly $0.16/kWh of gross margin before platform and processing fees; pricing per-minute at $0.10/minute is $6.00/hour, comfortably above the energy cost but exposed to the speed-fairness issue above. Whatever model you pick, run a sample session through it and confirm it clears electricity plus your per-session share of platform and processing cost.
Benchmark against nearby options. Check PlugShare and the apps of networks operating near you to see real local prices. Pricing well above the local market suppresses utilization; pricing below it gives away margin you could have kept.
Match the rate to the goal. An employer offering charging as a recruiting and retention benefit is not trying to maximize per-session revenue and may rationally choose free-with-idle-fees. A highway-adjacent retailer trying to recover capital wants a per-kWh or per-minute rate with real margin. Decide what the chargers are for before you decide what they cost.
Idle fees and overstay management
Once a vehicle finishes charging, the port is occupied but earning nothing (unless you are on per-minute pricing, which already penalizes overstay). At busy sites this throttles throughput and frustrates the next driver.
- Typical idle fee (as of Q2 2026): $0.40–$1.00/minute on busy DCFC sites is increasingly common, while Level 2 sites more often use $1–$2/hour. Most platforms let you configure a grace period and then escalate.
- Notify the driver. Idle fees only change behavior if the app or a text alert tells the driver charging is complete. An idle fee with no notification is just a surprise charge.
- Skip them at low-utilization sites. If your ports sit half empty, idle fees add friction without solving a problem you have.
California note
California operators face the highest energy and demand-charge exposure in the country. Commercial rates are well above the national average, and time-of-use tariffs mean the same kWh can cost very different amounts depending on the hour. If you price per kWh at a single flat rate while buying power on a TOU schedule, an afternoon-peak session can erase your margin. Two responses: price to your highest-cost period, or use software that shifts and shapes charging toward off-peak hours and reflects TOU in your retail rate. California has clarified that per-kWh EV charging billing is permitted, so the metering-and-margin question, not the legality question, is the one to focus on there. Your state page on this site lists the named PG&E, SCE, SDG&E, and LADWP EV rate and incentive programs; for the broader pattern of utility-side EV programs see Utility EV Charger Rebates: A Growing Incentive Layer.
Decision checklist
Changing rates over time
Nearly every network platform lets you adjust pricing in software, with no hardware changes. Set initial rates on the conservative side, watch real utilization for the first few months, and adjust. Chronically full chargers signal pricing power; chronically empty ones signal that a lower rate, or a different model entirely, may grow volume enough to matter. Pricing is not a one-time decision; treat it as a dial you tune against the data your platform already collects.
