Estimate your monthly Kenya Power postpaid electricity bill across every Kenya Power tariff category — Domestic, Small Commercial, Commercial 1–6, and E-Mobility — from your consumption or meter readings.

What tariff categories does this calculator cover?

Domestic (blended or forced to Lifeline 30/100), Small Commercial 1 and 3, Commercial 1 through 6 (by voltage level, each with a demand charge in KES/kVA and separate peak/off-peak rates), and E-Mobility — matching Kenya Power's full published tariff structure.

What is a demand charge?

Commercial tariff categories (Commercial 1–6) bill a separate demand charge based on your maximum recorded demand in kVA, in addition to the per-kWh energy charge. Domestic, Small Commercial, and E-Mobility categories carry no demand charge.
