About this model
An EV charging network model projects the financial performance of a rollout of fast-charging stations (150+ kW DC chargers) across 55 sites over ten years. Revenue comes from three streams: ad-hoc charging at $0.50/kWh (80% of energy mix), subscriber fees ($15/month plus $0.40/kWh for subscribers making up 20% of energy mix), and carbon credits at $80 per credit. The utilization ramp is the critical driver: new sites start at 3% utilization and ramp to 18% over 24 months - below 15% utilization, demand charges (a fixed monthly penalty per kW of capacity) overwhelm energy revenues and force unprofitability.
Capital expenditure per site is $550,000 gross, reduced by 40% government grants to $330,000 net, with a six-month construction delay before revenue commences. Operating costs include wholesale electricity at $0.15/kWh, demand charges at $15/kW/month (the kicker that makes low-utilization sites loss-making), payment processing fees (5% of revenue), and site lease costs (base rent plus 8% revenue share). Working capital is negligible (credit card settlements are fast). Debt is sized at 60% of cumulative net capex, with principal repayments commencing Year 3 after sites achieve stable utilization.
The model answers: when does the network achieve EBITDA-positive (target: Year 3 H2)? What is the site-level payback period? This template is calibrated for CPOs (Charge Point Operators) and infrastructure investors evaluating EV network build-outs under current subsidy and rate environments.
What every model includes
Live formulas, no hardcoded values
Outputs are driven by live formulas, so the workbook updates from its assumptions instead of relying on hardcoded results.
All assumptions in one tab
Inputs are clearly marked in the Assumptions tab and separated from calculations, making it clear what to change and what to leave intact.
Statements always balancing
For integrated-statement models, the balance sheet, cash flow, and supporting schedules tie through properly.
Distinct schedules for clarity
Debt, working capital, taxes, and cash flow can get messy quickly. We group calculations in clear schedules, not across disconnected tabs.
No hidden macros or external links
There are no unexplained external workbook links or macros to undermine auditability or portability.
Changes flow through the model
Update a key driver and see the impact carry through the forecast, financing, and return outputs. We never use hardcoded numbers in formulas.
What's inside the EV Charging Model
- Modular capex build for hardware, installation, and grid upgrades
- Revenue engine for kWh fees, session fees, and idle fees
- Advanced utility bill calculator with demand charges
- Carbon credit (LCFS/RIN) revenue modelling
- Pro forma with IRR, NPV, and break-even utilisation
- Capex by site type (retail, highway, workplace, residential)
- Installation and permitting costs by geography
- Utilization ramp: sessions per charger per day, growing with EV adoption
EV Charging Model: How This Financial Template Works
This EV charging model is a 10-year, monthly financial template for evaluating charge point operator rollouts. It links site construction, utilisation ramp, three revenue streams, electricity costs and project finance mechanics.
The guide explains what the template captures so you can judge whether its structure fits your own investment or development review. Rates and financial results described here reflect illustrative model settings, not industry benchmarks.
What Drives the Revenue Streams
The model builds revenue from three documented streams. Ad-hoc charging combines active chargers, hours per day, charger capacity and price per kWh, with subscriber charging adding a flat monthly fee plus discounted per-kWh rate.
- Carbon credits use dispensed energy, a carbon factor and a credit price. The design assumes 80% ad-hoc share, 20% subscriber share and a fixed subscriber count per mature site.
- Utilisation starts at 3% and ramps linearly to 18% over 24 months, capped at 40%. Each site follows its own ramp after opening, so later sites do not inherit early maturity.
How the Calculation Flows
Inputs on the assumptions sheet feed the rollout and operations sheet, then revenue, operating costs, capital expenditure and debt schedules. Active sites come from commissioning with a six-month construction delay, and active chargers accumulate without decommissioning.
- Energy costs divide dispensed energy by charger efficiency and apply a wholesale rate. Demand charges are separate fixed monthly costs based on site count, charger capacity, coincidence factor and a demand rate.
- Maintenance capital expenditure uses prior-period cumulative gross assets, which avoids circularity. Interest is charged on opening debt balances, and tax uses loss carry-forward.
Outputs and Financial Statements
The template produces a full three-statement model: income statement, balance sheet and cash flow, supported by debt, capital expenditure, depreciation, unit economics, returns and checks sheets.
- It captures EBITDA progression, free cash flow, working capital, depreciation by asset class, grant amortisation, DSCR testing and a terminal value calculation.
- The checks sheet tests balance sheet integrity, cash positivity, utilisation caps, DSCR covenant compliance and capacity limits.
- This gives a structured view of when the network may reach EBITDA positivity and how capital deployment affects returns.
Practical Use and Scope
This template is designed for infrastructure investors, site operators and project financiers assessing EV charging network rollouts. It is useful for testing the relationship between utilisation, demand charges and profitability, and for seeing how construction delays, grants and debt sizing affect cash requirements.
- The public download is a values-only preview, so it shows structure rather than live formulas. No scenario toggle is included, though reserved rows exist for future use.
- The model covers ad-hoc charging, subscriptions and carbon credits, and does not model other revenue streams or a debt service reserve account.

Created by ex-finance professionals
Hey, I’m Alex and I created Finamodel.
Over my years in the finance industry I kept building the same models over and over again. Same structure, same assumptions, different logo. So I started building frameworks to turn them into clean, reusable templates.
Every model here is one I’d actually use for a client, and I personally vet each one before it goes up.
I’m not an expert in every industry, but I’ve built enough models to know what belongs in one. And when something is completely foreign to me, I reach out to my network for experts to work on our models with us.
Having a template library on hand cuts a first build from hours to minutes.

Frequently asked
What is an EV charging financial model?+
It is a model that forecasts the revenue, costs, and returns of electric vehicle charging station deployments across their operational lifecycle.
Who uses EV charging models?+
Infrastructure funds, commercial real estate developers, fleet electrification managers, and sustainability officers use them for investment analysis.
What should an EV charging model include?+
It should include capex, session-based revenue, utility costs with demand charges, utilisation assumptions, carbon credits, and return metrics.
How do demand charges affect profitability?+
Demand charges are based on peak power draw and can represent up to 80% of the utility bill for DC fast chargers, making them a critical factor in station economics.
Does it support different location types?+
Yes. You can customise utilisation ramp-up schedules for different asset classes such as highway corridors, workplace charging, and multi-unit dwellings.
