About this estimate
The model uses session energy (charger kW and hours plugged in), your import and sale price per kWh, and how many active bays and sessions you assume. Monthly and annual figures are indicative. It is not grant or OZEV eligibility advice, tax advice, or payment-fee advice — real business EV charging performance varies with demand, hours and agreement terms.
FAQ
What does the EV charging ROI calculator estimate?
Potential charging revenue, electricity cost, and net income from your inputs. The figures are a model for commercial and workplace sites, not a guaranteed return.
How is monthly or annual income estimated?
The tool derives energy per session (power × time), applies your prices, scales by active bays and sessions, then rolls up to monthly and annual numbers as labelled. It is a planning illustration only, not accounting or tax advice.
Is this a guaranteed return?
No. The calculator is an EV charging revenue illustration only. Actual results depend on tariffs, hardware, usage, business terms and site specifics.
Does this show UK EV grants or OZEV?
The page can point you to funding. Schemes, caps and eligibility change. Use our grants hub and official sources to confirm. This is not legal advice.
What inputs change the result the most?
Usually: charger kW, time plugged in, sessions per bay, number of active bays, and your import vs customer kWh prices.
What is the difference between kW and kWh?
kW is the charger’s power. kWh is the energy used over time. The calculator uses both to build a session-based picture for your EV charging scenario.
Is this for workplaces, retail, or hotels only?
The tool is built for a wide range of UK commercial sites. Choose a preset or set your own inputs. Results still depend on your assumptions.
