Tariffs
The preset tariffs are in Belarusian rubles (BYN); the custom tariff works with any currency - the cost comes out in whatever currency you enter. The calculator automatically fetches the current household electricity tariffs of Belarus from energosbyt.by (refreshed daily). Apartments with a gas stove pay the regular tariff; homes with electric stoves and no gas get a subsidised, lower one. The two-zone tariff pays off if you have a two-rate meter and use much of your electricity at night. If the tariffs failed to load, enter your own - it is printed on your utility bill.
About power
The exact figure is on the appliance's nameplate or in its manual; the table gives typical ranges. Thermostat-controlled appliances (refrigerator, water heater, iron, space heater) run in cycles, so their average consumption is well below the nameplate power: for those it is fairer to use an average value or meter readings.

The current an appliance draws from the socket is easy to estimate with the Ohm's law calculator (2000 W at 230 V is about 8.7 A), and the wire size for the load - with the wire cross-section table.
