The arithmetic
Take a 3.5 kWh battery. Allowing roughly 10% for charging losses, a full charge from empty draws about 3.9 units from the wall. With a real-world TrueRange of about 130 km, that is roughly 0.03 units per kilometre.
| Your electricity rate | Cost of a full charge | Cost per km |
|---|---|---|
| ₹6 per unit | ≈ ₹23 | ≈ 18 paise |
| ₹8 per unit | ≈ ₹31 | ≈ 24 paise |
| ₹10 per unit | ≈ ₹39 | ≈ 30 paise |
Your rate depends on your tariff slab — check the per-unit figure on your latest electricity bill and use the closest row.
Compared with petrol
A typical 110 cc petrol scooter managing about 45 km per litre costs:
| Petrol price | Cost per km | |
|---|---|---|
| Chennai (9 Nov 2026) | ₹107.77 / litre | ≈ ₹2.39 |
| Puducherry (1 Nov 2026) | ₹103.58 / litre | ≈ ₹2.30 |
At around 24 paise per km, an Ather costs roughly a tenth as much to run on energy alone.
A month of commuting
Riding 1,000 km a month — about 40 km a day, 25 days a month:
- Petrol scooter in Chennai: about ₹2,390
- Ather, charged at home at ₹8/unit: about ₹240
That is a difference of around ₹2,150 a month, or about ₹25,800 a year, before service savings. Our cost of ownership guide adds servicing and other costs.
What about fast charging?
Ather Grid fast charging is priced per session or per unit in the Ather app and costs more than charging at home. Use it to top up on long days; do most of your charging at home to keep costs lowest.
