Which Electricity Tariff Is Cheaper for Your Usage?
Compare two electricity tariff scenarios using the same consumption profile. Include fixed charges and an optional escalation assumption to see how the difference behaves over a longer planning period.
Why a low energy rate is not always the cheapest tariff
A tariff includes more than the headline energy price. Fixed charges can offset a lower per-kWh rate, especially for customers with relatively low consumption.
Compare tariffs using the same demand
A fair comparison starts with the same consumption profile. Changing the usage between scenarios can make the tariff comparison meaningless because it mixes pricing effects with behavioral changes.
Longer-term sensitivity
Electricity prices and fixed charges may change over time. The optional annual growth assumptions let you test a planning scenario rather than treating today's prices as permanent.
What this tool does not model
It does not model time-of-use intervals, demand charges, tiered blocks, taxes or utility-specific eligibility rules. Those require a more detailed tariff model.
FAQs
Can a higher fixed charge still produce a cheaper bill?
Yes, if its lower energy price saves enough money at the selected consumption.
Why include annual growth?
It lets you test how a tariff difference behaves over time under a chosen scenario.
Does this use live utility pricing?
No. Enter the current or quoted tariff values that apply to your situation.
Can this compare time-of-use plans?
Use a dedicated time-of-use model when different rates apply to different periods.
