How electricity bills are generally calculated
One unit means one kilowatt-hour (kWh): using a 1,000-watt appliance for one hour consumes roughly one unit. Many tariffs divide consumption into slabs, with a different rate applying to each range. Fixed charges, duties, taxes, fuel adjustments, meter charges, and local rules can then change the final bill.
How TechVodka calculates your electricity bill
Custom Rate mode multiplies your units by the rate you enter, then adds any optional fixed charge. Actual bills can differ because DISCOM rules and adjustments vary.
