What changes this most?
Compare both unit rate and standing charge; their relative impact depends on how much energy the household uses.
Sensitivity check
A roughly 10% move in new unit rate per kwh changes the modeled headline result by up to $109 in this setup.
This keeps annual usage fixed so the result isolates tariff changes.

Formula
Old and new annual bills are calculated from the same annual kWh plus each unit rate and standing charge.
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.
