How much does it cost to charge an electric bike?

Updated 6 Nov 2026

About Rs 58 to Rs 153 for a full charge, and about Rs 1,024 a month if you ride 40 km a day. It depends on your battery size and what you pay per unit.

The simple formula

Battery size in kWh ÷ 0.85 = units used for a full charge. (Chargers lose about 15% as heat.) Multiply by what you pay per unit. Example: the Yadea GT30's 1.38 kWh battery ÷ 0.85 = about 1.6 units. At Rs 36.46 a unit, that's about Rs 58.

Find your real rate

Take the total on your last K-Electric bill and divide it by the units used. That's your true cost per unit, taxes included. NEPRA A-1 residential 301–400 unprotected slab: Rs 36.46/kWh.

Watch the 200-unit line

Protected status needs 200 units a month or less, for six months in a row. Riding 40 km a day adds about 28 units a month. If you're close to 200, charging could cost you protected status and raise the rate on every unit.

Charging safely

Use a proper wall socket, not an extension reel. Charge in a dry, airy place. Unplug when the charger shows full, unless the manual says otherwise.
