Monthly Electricity Calculator
(Domestic)
Example with Your Mini PC (12 hours daily)
Assume average power = 10W (typical for efficient N100 mini PC in mixed use):
- Daily Wh = 10W × 12 hours = 120 Wh
- Daily kWh = 120 ÷ 1000 = 0.12 kWh
- Monthly units = 0.12 × 30 = 3.6 units
Or using the combined formula:
(10 × 12 × 30) ÷ 1000 = 3600 ÷ 1000 = 3.6 units/month
If average power is higher (e.g., 15W during moderate use):
(15 × 12 × 30) ÷ 1000 = 5400 ÷ 1000 = 5.4 units/month
Your Calculation Result:
Approximate Domestic Slabs (2025–2026)
| Monthly Units | Rate per unit (₹) | Fixed Charge (₹/month) |
|---|---|---|
| 0 – 50 | ₹ 3.00 – 3.95 | ₹ 0 – 10 |
| 51 – 100 | ₹ 4.30 – 5.30 | ₹ 10 – 25 |
| 101 – 200 | ₹ 6.00 – 7.00 | ₹ 25 – 50 |
| Above 200 | ₹ 7.50 – 11.00+ | ₹ 50+ |
Note: This is an approximate slab used for low-usage calculation (most mini PC users fall in 0–100 units slab).
