How much does charging your scooter at home cost?
Charging cost = the units your meter gives up × your tariff per unit. Taking a 3.5 kWh scooter from 20% to 90% puts 2.5 kWh into the battery but pulls about 2.9 units from the meter once charging losses are counted, so at ₹8 a unit that overnight charge costs about ₹23 — close to 30 paise a km at 3 kWh per 100 km.

How this is calculated: The meter cost uses grid draw, not battery stored energy, because charging losses happen between the plug and the battery. Scooter efficiency figures are inferred from the real-world range midpoint when a model is selected. Actual range varies with speed, load, and terrain.
What this calculator does and does not model
What it models: The cost of a single home charging session based on your scooter battery size, charge window, and home electricity tariff. India scooters typically have 2.5–4 kWh batteries. Charging at home from 20% to 90% costs between ₹14 and ₹28 at a ₹8/kWh tariff — far cheaper than petrol for the same distance.
What it does not model: Proprietary fast-charging networks (such as Ather Grid) use a different per-minute pricing structure and are not covered here. Swap-battery products (such as Bounce Infinity or Sun Mobility) do not apply to this tool at all — their cost model is a subscription, not a per-session charge.
Efficiency figures: When a scooter is selected from the catalog, efficiency is inferred from the midpoint of the manufacturer-reported real-world range. For example, a scooter with a 4 kWh battery and a 120–140 km real-world range gives an inferred efficiency of 3.1 kWh/100 km. This is an estimate — your actual figure depends on speed and load.
Electricity rate by state
What does a unit of electricity cost in your state?
Home charging cost depends mostly on your per-unit rate. These are residential energy charges from each state's current tariff order for a typical household slab — fixed charges and taxes are extra, and some states give free or subsidised units each month, so your bill shows your real rate.

FAQ
Common questions about scooter charging costs
Most Indian states charge domestic consumers between ₹5 and ₹10 per kWh. Check your electricity bill for the per-unit rate in your tariff slab. Rates in metros like Mumbai, Bengaluru, and Delhi typically fall between ₹6 and ₹9 per kWh.
Your scooter's onboard charger converts AC mains electricity to DC before it enters the battery. That conversion produces heat and loses around 10–15%. At 85% charging efficiency, a 2.4 kWh top-up draws about 2.8 kWh from your meter — and that is what your bill reflects.
No. Swap-battery scooters (such as those on Sun Mobility or Bounce Infinity networks) work on a subscription or per-swap fee, not a per-kWh home charging cost. This tool only applies to plug-in scooters.
No. Ather Grid uses a per-minute pricing model at proprietary stations. This tool is built for home AC charging where you pay a flat per-unit electricity tariff.
When you select a scooter, efficiency is calculated from the midpoint of the manufacturer real-world range. For example, a 4 kWh battery with a 120–140 km range gives 3.1 kWh/100 km. Your actual figure depends on speed, rider weight, and terrain.
