L2 Estimator
Instant clarity on L2 charger ROI
We turn “Should we add a charger here?” into “Here’s what this charger can earn over the next 5 years.”
What it answers
“Will this Level 2 charger actually make money — and how long until it pays for itself?”
Time to insight
Under 3–5 minutes with your numbers.
Built for
Site hosts, installers, developers, lenders.
Turn Your L2 Charger Into a Predictable Revenue Stream
The L2 Charging Station Estimator models a single Level 2 charger (or a small group) from the perspective of the site host. It combines driver pricing, utilization, hardware and install costs, network fees, and utility rates to show the full 5-year business case.
In a few fields, you can see:
Monthly and annual charging revenue based on your driver pricing.
Utility costs that include kWh, fixed fees, and optional demand charges.
Net profit and cash flow after all operating expenses.
5-year net profit and payback period including hardware and installation.
Optional additional revenue from dwell-time spending (restaurant, retail, parking, etc.).
Inputs You Control
The estimator is built around numbers that site hosts, installers, and project developers already use in their proposals and budgets. You can customize everything that moves the ROI.
✔ Utilization
Average charging sessions per day.
Average session length or kWh per session.
Days per week the charger is typically used.
Optional seasonal / weekday vs weekend adjustments (if enabled in your version).
✔ Infrastructure
Hardware cost for the L2 charger.
Installation cost (trenching, panel, labor, etc.).
Network / software fees (monthly or per port).
Any additional fixed monthly costs you want to include.
✔ Driver pricing
Per-kWh, per-session, or blended pricing structure.
Minimum session fee (if you use one).
Optional revenue-sharing or driver discounts in your pricing strategy.
What You Get Back
Once your assumptions are in, the estimator calculates a clear set of business metrics that you can drop directly into proposals and investment conversations.
Financial Metrics
Utility cost breakdown (energy, fixed fees, and optional demand charges).
Network and other operating costs rolled into a simple Opex view.
Annual net profit after all operating costs.
5-year net profit including upfront hardware and installation.
Payback period in years and months.
Utility & Efficiency
Base utility rate ($ / kWh) — or pulled from a utility API (if available)
Fixed monthly service or meter fees.
Optional demand charge input for higher-load sites.
This gives a realistic view of what electricity really costs, not just a simple cents-per-kWh guess.
Tax Incentives
Federal tax credit estimate (30% of project cost, up to the allowable limit)
Location-based eligibility (census tract verification when applicable)
State or utility rebates available for hardware or installation
Impact on upfront cost after incentives
Updated payback period reflecting incentive-adjusted project cost
Additional Revenue
Estimated extra spend per session (coffee, food, retail, parking).
Average margin or share of that spend the site host keeps.
Perfect for restaurants, hotels, retail, and mixed-use sites where charging time = dwell time.
Note: All results are estimates based on the assumptions you enter. Actual performance will vary by utilization, pricing, and local utility rates.
Supporting details
kWh delivered per year from your assumptions.
Average revenue per session and per kWh.
Effective cost of electricity (all utility components rolled into ¢/kWh).
Optional dwell-time revenue by year from on-site spending.
These metrics let you answer “Is it worth it?” in a way that works for site hosts, investors, and lenders.
Environmental
Annual CO₂ emissions avoided compared to gasoline use
kWh delivered per year and equivalent EV miles supported
Conversion to recognizable metrics (e.g., gallons of gasoline avoided, trees planted equivalent)
Five-year cumulative environmental benefit
