Questions
Frequently asked questions
How do you calculate EV charging hub payback?
Start with the upfront investment, then add up each year's operating profit from energy sales after electricity, payment fees and running costs. Payback is the point where cumulative profit covers the investment.
What utilisation does a charging hub need?
It depends on prices and costs. The calculator shows how many sessions per point per day you need to cover running costs at your figures.
What has the biggest effect on charging hub profitability?
Utilisation, the margin on each kWh and the cost of the grid connection usually matter most.
Does the calculator include VAT and financing?
No. It uses simple, undiscounted cash flows and excludes VAT, financing, tax and depreciation.
Can grants improve the payback?
Grants or contributions reduce the upfront cost. Enter them to see the effect, and check eligibility before relying on them.
Is the result financial advice?
No. It is an illustrative planning estimate. Use quotes, tariffs and demand data for your own site.
