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.
Adjust one assumption at a time to understand which inputs have the greatest effect. Compare several realistic scenarios rather than relying on a single projection.
Default assumptions are maintained by FinTrex and may not reflect current products or rates available to you. Review every input before using the estimate.
