How the ROI calculator works
Pick a charger (AC 22 kW to DC 240 kW — it fills in a typical investment), set your active charging hours per day, and the calculator works out the units you dispense. It makes money on the spread between electricity bought at the concessional EV tariff (around ₹5–7 per unit) and charging sold to drivers (around ₹15–18 per unit), minus a per-unit platform/maintenance cost. Subtract any government subsidy from your investment, and you get monthly and annual net profit, ROI% and the payback period, plus a 5-year net earnings figure. The single biggest lever is utilisation — how many hours the charger is actually used.
The single biggest variable is utilisation — how many units you actually sell. Average charger usage in India is still low, so a great location makes the difference between a 2-year payback and never breaking even. Read our honest take on whether the charging business is profitable, the full setup cost breakdown, and how subsidies cut your upfront investment.
The economics in plain terms
An EV charging station is, at its core, a very simple business: you buy electricity wholesale and sell it retail. In most states a commercial EV charging connection is billed at a concessional tariff of roughly ₹5–7 per unit, and drivers typically pay ₹15–25 per unit at a public charger. Your gross spread is therefore around ₹8–18 per unit. Out of that spread come your real costs: platform and payment-gateway fees, maintenance and spares, site rent or revenue share, manpower if the site is attended, insurance and the slow erosion of the hardware itself.
What surprises most first-time operators is that the machine's rating tells you almost nothing about earnings. A 60 kW DC charger does not earn twice a 30 kW charger; it earns whatever the cars plugged into it consume. This is why the calculator asks for active charging hours per day rather than capacity alone. A 30 kW charger genuinely busy for six hours a day dispenses about 180 units, which at a ₹10 spread is roughly ₹1,800 a day of gross margin — close to ₹54,000 a month before costs. The identical charger sitting idle for all but ninety minutes a day dispenses 45 units and struggles to cover its own electricity demand charges.
What realistic utilisation looks like in India
Public charging in India is still maturing, and honest utilisation numbers are far lower than the spreadsheets circulating on social media suggest. A newly commissioned charger in a mid-sized city often sees one to three sessions a day in its first few months. Growth comes from becoming known: appearing on the charging maps drivers actually use, having a reputation for working, and sitting somewhere people already need to stop.
The sites that reach healthy utilisation quickly tend to share characteristics. Highway and expressway corridors with genuine EV traffic — the Mumbai–Pune, Delhi–Jaipur and Bengaluru–Chennai routes being obvious examples — deliver long, high-value DC sessions. Urban locations where people already park for 30 to 60 minutes, such as malls, restaurant clusters, cinemas and large offices, convert dwell time into units sold. Fleet and delivery hubs are the quiet winners: cab aggregator drivers and delivery riders charge daily, predictably, and in volume, which is exactly the kind of base load that makes a station's numbers work. Conversely, a charger installed simply because a plot of land was available, with no traffic reason to stop there, is the most common way money is lost in this business.
Reading your payback period honestly
The calculator gives you a payback period, but treat it as a range rather than a promise. Model three scenarios: a pessimistic case at roughly half the utilisation you expect, a base case at what you genuinely believe, and an optimistic case. If the business still makes sense in the pessimistic case, the site is worth pursuing. If it only works in the optimistic case, you are betting on traffic that may take years to materialise.
Two adjustments make the model more truthful. First, remember that electricity bills for commercial connections often include fixed demand charges based on sanctioned load, which you pay whether or not a single car plugs in — this is why an under-used DC station bleeds money rather than merely earning little. Second, budget for hardware reality: connectors get damaged, communication modules fail, and a charger that is offline earns nothing while still costing you rent and demand charges. Operators who set aside a maintenance reserve from day one are the ones whose real-world returns resemble their spreadsheets.
How subsidies change the picture
Capital subsidy is the single fastest way to shorten payback, because it reduces the denominator in every return calculation without touching your running costs. The central PM E-DRIVE scheme has allocated dedicated funding for public charging infrastructure, and several states layer their own capital subsidies, concessional EV tariffs and single-window approvals on top. Where these apply, they can meaningfully reduce the effective cost of your hardware and electrical work.
To model this, simply reduce the total investment figure by the subsidy you realistically expect to receive, and compare the payback with and without it. Two cautions from people who have been through the process: subsidies are usually reimbursed after commissioning rather than paid upfront, so you must still fund the full cost initially; and eligibility often depends on using approved equipment and following the documentation process exactly. Our charging station subsidy guide covers what applies where.
Costs people forget to include
Hardware is the visible cost; the invisible ones decide your returns. Budget for the electrical infrastructure — a DC fast charger frequently requires a new transformer, an upgraded sanctioned load and cabling work that can rival the charger's own price. Add civil work for the pad, canopy, lighting and signage, all of which also affect whether drivers feel safe stopping at night. Include network and software costs, since a modern charger needs connectivity, a payment layer and remote monitoring. Then account for site cost, whether that is rent, a revenue share with a landowner, or the opportunity cost of your own land.
Finally, plan for the ramp-up period. Very few stations reach their steady-state utilisation in month one, so hold enough working capital to run at a loss for the first several months while drivers discover you. Being listed and visible matters here: our charging station map is how many EV owners find a charger in the first place, and reliability is what makes them return.
Frequently asked questions
How do you calculate EV charging station ROI?+
ROI comes from the spread between what you pay for electricity (the EV tariff, ~₹5–6.50/kWh) and what you charge customers (~₹12–18/kWh), multiplied by the units you sell, minus operating costs. Monthly net profit divided into your investment gives the payback period; annual net profit over investment gives the ROI percentage.
What is a realistic payback period for a charging station?+
Well-located urban fast-charging sites typically pay back in about 2–4 years, and larger sites 3–5 years — but only if they are genuinely used. Average charger utilisation in India is still low, so a station in a low-traffic spot can take much longer or never break even. Model conservatively.
How much can an EV charging station earn per month?+
It depends almost entirely on utilisation. A busy charger dispensing a few hundred units a day can earn strong five-figure monthly profits, while a quiet one may barely cover costs. Use the calculator with your realistic daily units to see your own figure.
Do subsidies improve the ROI?+
Yes — PM E-DRIVE and state capital subsidies can cover a large share of the upfront cost, which directly shortens the payback period. Lower your 'total investment' input by the subsidy you expect to claim to see the effect. See our EV charging station subsidy guide for what applies.
