My electricity provider just switched me over to a dynamic tariff and prices change every hour. I'm trying to figure out how I can even calculate my monthly costs anymore when the kWh prices keep fluctuating. Is there some kind of mathematical formula to make sense of this?
Most providers give you a detailed breakdown where every hour with its price is listed - that's your best source for the exact calculation. Mathematically it comes down to calculating (consumption in kWh) × (hourly rate in €/kWh) for each hour and then adding it all up, but honestly at a larger scale that's too tedious to do by hand 😅 Check your online portal or your bill - it should already be summarized there - or just ask your provider directly how they break down the calculation.
