EnCalcEU calculates the cost of electricity, allowing the cost based on meter readings and forward prediction based on the readings and elapsed time. The results can be saved to a log file. EnCalcEU copes with different charging rates for electricity, alternative rates based on a threshold, varying tax rates and fixed charge. It also calculates the amount of CO2 generated. Requires a registration code (free for personal non commercial use).
