Total Bill = (Units consumed in each slab × slab rate) + Fixed charges + Additional charges (if any)
Here’s an example to help you understand how to calculate Tamil Nadu electricity bill manually:
Example: You used 450 units this month (Domestic connection).
- 0-100 units = Free
- 101-400 units = 300 × ₹4.70 = ₹1410.00
- 401-450 units = 50 × ₹6.30 = ₹315.00
Total bill = ₹1410.00 + ₹315.00 = ₹1725.00 (excluding fixed charges or taxes)
