Your bill is local.
The working should be universal.
Turn an electricity bill, appliance label, solar estimate or project measurement into a decision you can inspect. Choose your own currency, rates and units—then see every formula and limit.
What are you trying to understand?
Why did my bill change?
Separate billing days, daily use, rate and fixed-charge effects.
Resolve thisWhich plan is cheaper?
Compare flat and peak/off-peak rates on the same kWh.
Resolve thisIs solar I use worth more?
Value self-use and export at different rates.
Resolve thisDid I mix my project units?
Convert first, then calculate quantity and packages.
Resolve thisBuilt around the question after the number
These tools explain which cost moves, which charge stays, and which source to verify.

Each pack explains local rate structures, official sources, labels and units without silently locating you or applying a national average.
United States
US bills vary by utility, state, season and rate design. GharGanit therefore starts with the customer's own bill instead of publishing a national price.
Open USA pack 02GBUnited Kingdom
A UK household can pay a daily standing charge plus one or more unit rates. The calculator keeps those pieces separate so a usage saving is not overstated.
Open UK pack 03AUAustralia
Australian plans may combine a daily supply charge, flat or time-of-use usage and solar feed-in credits. Results remain scenarios until checked against the retailer plan.
Open Australia pack 04AEUnited Arab Emirates
UAE utility structures differ by emirate and customer type. The Dubai tool uses editable DEWA slab and surcharge inputs and links to the current official tariff page.
Open UAE pack 05CACanada
Provincial utilities and rate structures differ. GharGanit uses the household's own rate and official EnerGuide or utility information where available.
Open Canada pack 06EUEuropean Union
EU labels and EPREL help identify product performance, but the local tariff and usage pattern still determine cost. Those values stay editable.
Open EU pack 07NZNew Zealand
Use the retailer bill, product label and EECA guidance together. No single default rate or heating performance figure is treated as national fact.
Open New Zealand pack 08SGSingapore
Singapore's climate makes cooling and dehumidification important, while tariff information is regularly updated. Users enter the current rate they actually pay.
