Your estimated consumption exceeds 300 units/month. Consider: upgrading to 5-star rated appliances, setting AC to 24°C instead of 18°C (saves ~36%), using LED lights, and switching off appliances at the plug when not in use. These steps can reduce your bill by 20–35%.
Disclaimer: The estimated bill is based on a flat per-unit rate. Actual electricity bills include slab-based tariffs, fixed charges, meter rental, government taxes, and surcharges. Refer to your DISCOM website or your electricity bill for exact tariff details applicable to your connection category.
