1 Unit Electricity Price by State (2026)
There is no single national price — each state sets its own home tariff. For a home using 200 units a month, one unit costs from ₹3.00 in Delhi to ₹8.98 in Maharashtra, before subsidies, fixed charges and duty. Higher slabs cost more: Maharashtra's top slab is ₹19.13 per unit.

How This Calculator Works
One unit of electricity = 1 kilowatt-hour (kWh) — the energy a 1000-watt appliance uses in one hour. Multiply units by your tariff to get the cost.
Example: A 7.5 kW motor running 8 hours/day consumes 60 kWh/day. At ₹8/kWh, that's ₹480/day or about ₹12,480/month (26 working days).
Typical Indian Tariffs (2026)
| Category | Range (₹/kWh) |
|---|---|
| Domestic (low slab) | ₹3 – ₹6 |
| Domestic (high slab) | ₹6 – ₹19 |
| Commercial | ₹8 – ₹11 |
| Industrial LT | ₹6 – ₹10 |
| Industrial HT | ₹6 – ₹9 |
Always check your latest bill for the applicable rate — varies by state.

Electricity Cost Formula Explained
The basic electricity cost formula is straightforward: total energy used (in kWh) multiplied by the per-unit tariff (₹/kWh). The tricky part is figuring out total energy used — that depends on the load (in kW) and how long it runs (hours).
Worked Example — Home AC
Daily Energy = 1.5 × 8 = 12 kWh/day
Daily Cost = 12 × ₹7 = ₹84/day
Monthly Cost = 84 × 30 = ₹2,520/month
Worked Example — Factory Motor
Actual Power = 7.5 × 0.80 ÷ 0.90 = 6.67 kW
Monthly Energy = 6.67 × 8 × 26 = 1387 kWh
Monthly Cost = 1387 × ₹8 = ₹11,093/month
