About electricity bill calculator
Many states bill electricity in slabs, where each additional block of units costs more. The calculator adds up the slab charges, fixed charges and taxes.
How a typical bill is built
- Energy charge: units in each slab × the slab rate.
- Fixed or demand charge, based on your sanctioned load.
- Fuel and power purchase adjustment, which changes monthly.
- Electricity duty and taxes.
Use your own tariff
Enter the slab rates from your electricity board's latest tariff order. These differ for each state and for homes and shops.
A worked example
Take 250 units with slab rates of ₹3 for the first 100, ₹5 for the next 100 and ₹7 above that, plus a fixed charge of ₹50. Energy charges are 300 + 500 + 350 = ₹1,150, so the bill before taxes is ₹1,200. Reducing use by 50 units would save ₹350, since the top slab is the most expensive.
Why the top slab matters
Slab billing means your last units cost the most. Cutting use at the margin, for example by turning off an AC an hour earlier, saves more than the average rate suggests.
