Wonder which appliance is eating your units? Set how many you have and how long each runs per day, and this calculator estimates your monthly units — and roughly what that adds to a PESCO bill.

Indicative only. Wattages are typical running figures — real draw varies by model, setting, age and ambient temperature (an air conditioner works harder in June than in October). Appliances that cycle, like a refrigerator, are shown at an average draw. For the exact bill, use the Bill Estimator with your metered units.
For each appliance, enter how many you have and how many hours a day it runs.
Units per month and an approximate energy cost recalculate live as you type.
See which appliances dominate, then trim hours on the big ones to bring units down.
Validate your 14-digit reference number and jump straight to the official PITC portal for your bill.
