Advanced Billing Options Solar net-metering, ToD, arrears & penalties
Enter amounts exactly as shown on your previous bill. LPSC on previous arrear is a direct amount, not computed.
LPSC is enabled by the “LPSC Applicable” toggle on the Meter Read tab. These fields set the rate and how many months the current bill is overdue.
Payments already made during this billing period — these reduce the total amount due.
Any miscellaneous credits or charges — e.g., meter cost, security deposit refund, or rebate. Use negative values for credits.

TheDiscomBill is a free, browser-based electricity bill calculator that covers all Distribution Companies (DISCOMs) across India — from BESCOM in Karnataka to MSEDCL in Maharashtra, PSPCL in Punjab, TANGEDCO in Tamil Nadu, and dozens more. Simply select your state, choose your DISCOM, pick your consumer category, enter your units consumed, and get an instant provisional bill with a complete slab-wise breakdown.
Beyond the calculator, TheDiscomBill publishes current tariff rates for every state, a guide to reading your smart meter, an instant self-check that reads your bill photo, and calculators for rooftop solar and EV charging — all free, in English, हिंदी, मराठी and தமிழ்.
How the calculator works
The calculator uses the latest publicly available tariff orders from each DISCOM. It computes charges using the slab-wise (cumulative) method: the rate for each slab applies only to the units consumed within that slab, not to the entire consumption. Fixed / demand charges are applied separately based on your connected (sanctioned) load.
Electricity Duty, fuel adjustment charges, and other state levies are applied as specified in each DISCOM's tariff schedule.
