Write down every load’s nominal power.
Convert to kVA (PF 0.90): ( 21.1 / 0.90 = ) The "Real" Calculator: Power Analyzer / Smart Meter Manual calculations are estimates. For accurate MD (and to verify your diversity assumptions), you need real data. maximum demand calculator

In the world of electrical engineering and facility management, Maximum Demand (MD) is a critical metric. It isn't just about keeping the lights on; it directly impacts your capital expenditure (cable/transformer sizing) and operational expenditure (electricity bills). Disclaimer: This guide provides estimation methods
Grab your last 12 utility bills. Find the highest "Demand" value. Compare it to the sum of your connected load. You will likely find you are paying for capacity you rarely use.
[ MD = (Load_1 \times DF_1) + (Load_2 \times DF_2) + ... + (Load_n \times DF_n) ]
