Electricity bills in Karnataka are computed by multiplying the amount of power units consumed by the user with slab-based tariff rates, followed by the addition of fixed rates, FPPCA (Fuel Cost Adjustment), applicable taxes, and government levies. To get the final bill, you need to subtract any subsidies (like Gruha Jyothi) from the total result.
Here is the general formula if you want to know how electricity bill is calculated in Karnataka:
Total Bill = (Fixed Charges + Energy Charges + FPPCA + Surcharges/Duties) + Taxes - Subsidies
How is the Electricity Bill Calculated in Karnataka?
Determine the units you consumed. You can get this by deducting the previous meter reading from the current meter reading (Units = Current meter reading – Previous meter reading). Also, remember 1 unit is equal to 1 kilowatt-hour.
Apply a slab-wise electricity charge. Different rates correspond to varying levels of consumption.
In this case, a low rate is applied to lower units.
Per-unit rates rise in response to increased consumption.
Now, add fixed charges. A sanctioned load (kW/HP) and connection type (single-phase or three-phase) determine the fixed rates. Even little consumption is subject to these fees.
Add Fuel and Power Purchase Cost Adjustment (FPPCA). The Karnataka Electricity Regulatory Commission (KERC) sets this variable fee to compensate for variations in power purchase costs. It is computed per unit consumed and updated regularly.
Add surcharges to the result. You need to add the latest surcharge or electrical duty charge.
Add electricity tax (GST). The bill includes an electricity tax (a percentage of energy charges) imposed by the Karnataka government.
Subtract Gruha Jyothi Subsidy from your total amount. If you have registered under this scheme, you will get up to 200 units of free power. It will drastically lower your bill, with the exception of fixed fees and FPPCA for usage over 200 units.
