EV Charging Site Revenue Calculator

Standalone DC fast charging stations generate revenue based on utilization and kWh rate.

Annual revenue

Annual gross margin

$173,448

Margin %

0.69%

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 this calculator works

What this page estimates

This EV Charging Site Revenue Calculator is built to give a quick, browser-based estimate for ev charging site revenue. Standalone DC fast charging stations generate revenue based on utilization and kWh rate. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.

Calculation approach

The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.

Example workflow

For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.

Practical checks

Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
Run a low, base, and high case when the inputs are estimates.
Check the related calculators below when the next decision depends on a different assumption.

How to interpret the ev charging site revenue result

Best use

Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.

Cross-check

Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.

Watch for

Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.

This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.

Before relying on this ev charging site revenue estimate

Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.

Confirm source numbers

Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.

Separate cash flow from total cost

A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.

Run conservative cases

Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.

Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

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.
