Is this electricity bill calculator exact?

No. It is an estimate. Actual Indian electricity bills depend on your sanctioned load, tariff category, subsidy, fuel adjustment charge, taxes, meter rent, billing cycle, and provider updates.

Which appliance usually increases the bill most?

Air conditioners, geysers, pumps, and old refrigerators usually add the most units because they draw high wattage or run for many hours.

How do I calculate monthly electricity units?

Use units = watts x hours per day x days / 1000. For multiple appliances, multiply by the quantity and add all appliance units.

Why does the bill rise sharply after some units?

Many Indian domestic tariffs use slabs. Once consumption crosses a slab limit, additional units are charged at higher rates and sometimes fixed charges or duties also change.
