Electricity bill estimator
Combine meter usage, unit price and a daily standing charge.
A clear answer. Here’s how.
Usage = end reading − start reading. Subtotal = usage × unit price + days × standing charge. Applies only the additional tax percentage you supply. Requires increasing kWh readings; rollover, export, dual rates and tariff-specific rules are excluded.
