Energy-use charge

What changes this most?
A tariff with a lower unit rate can still cost more for low-use households if its standing charge is higher.
Sensitivity check
A roughly 10% move in annual energy use changes the modeled headline result by up to $105 in this setup.
Tariffs change. Replace defaults with your current tariff or a source-dated benchmark.

Formula
Annual energy cost equals annual kWh × unit tariff plus daily standing charge × days.
kWh and standing charge are kept as separate inputs to avoid confusing energy usage with fixed tariff charges.
Editable rates, growth assumptions, prices, fees, and percentages are planning inputs unless the calculator explicitly identifies a current source.
