Monetary amounts are in Romanian lei (RON) unless another currency is selected. Salary and VAT calculators use Romanian rules; changing language does not switch tax jurisdiction.

How it is calculated

Usage (kWh) = power (W) / 1,000 × hours per day × days used. Cost = usage × final tariff per kWh.

The 1.30 RON/kWh tariff is only an example. Enter your final contract price including taxes. Rated power does not reflect duty cycles; fixed subscriptions are excluded.
