Home Bill Shock Checker
Per-day normalized month-on-month and year-on-year bill comparison with cause checklist.
Bill double this month? Before calling the DISCOM, run the three numbers: this bill, last bill, same month last year — per-day normalized. Half of all bill shocks are a 33-day cycle meeting a 28-day memory; the other half have a real cause this tool helps narrow.
If unexpected: check meter reading vs bill (estimated readings catch up later), tariff revision, or a billing-cycle length change.Per-day normalization removes the 28-vs-33-day billing-cycle illusion that explains half of all "bill shock" complaints for a household.
Indicative estimates only, not financial or investment advice. Tariffs, subsidies and net-metering rules change — verify with your DISCOM, utility or installer before committing.

Frequently asked questions
Why is my electricity bill suddenly high?+
Run the honest comparison first: per-day units against the SAME month last year. Half of bill shocks are a 33-day cycle meeting a 28-day memory, or seasonality. A real YoY jump beyond ~15% with unchanged living patterns points at: new/failing appliances (dying fridge compressors are classic), meter-reading errors, or estimated readings catching up.
How do I check if my meter reading is correct?+
Photograph the meter today, compare against the bill's 'current reading'. Estimated bills (marked 'E' or 'average') true-up later — a catch-up month looks like a spike. Two consecutive suspicious readings justify a written meter-test request to the DISCOM (small fee, refundable if the meter's fast).
Can a single appliance really double a bill?+
Easily: a failing refrigerator running continuously adds 100–150 units/month; a stuck water-heater thermostat 150–250; an AC with dirty filters 30–50% over its normal draw. The appliance-cost calculators on this site help you hunt the suspect by pricing each one's expected consumption.
When should I file a billing complaint?+
After documenting: meter photo vs billed reading, the per-day YoY math from this tool, and notes on any 'estimated' flags. With that file, DISCOM grievance cells (and forums beyond) resolve quickly. Without it, complaints stall — the documentation IS the complaint.
