Appliance Label Annual Cost Calculator

Energy labels are strongest when the exact model's annual kWh is combined with the household's own rate. Enter the label figure, rate and planning years. The tool does not infer annual kWh from a star, letter grade or product category, and it does not treat a multi-year energy estimate as the purchase price or total cost of ownership.

What to have beside you

Use the current bill or tariff sheet, exact product label, location-specific solar estimate, or measured project dimensions. Example physical values teach the tool; zero money rates prevent an unsourced price from becoming a default claim.

This prices the label's annual energy at one unchanged entered rate. It does not rank products or include purchase and service costs.

How this was calculated

Formula used

Annual energy cost = label kWh/year × entered rate; period energy cost = annual cost × years

Your values in the formula

300 kWh/year × $0.00 = $0.00/year

Assumptions and rounding

The label annual kWh comes from standard test conditions.
The period view assumes the same rate and label energy every year.

Label test conditions may differ from actual use. Tariff changes, maintenance and purchase cost are excluded unless compared separately.

What the result means

Use it as a scenario

Label test conditions may differ from actual use. Tariff changes, maintenance and purchase cost are excluded unless compared separately.

A model labelled 300 kWh/year uses 1,500 kWh over five label-years before any rate change is assumed.

What can change

Check before deciding

01Use the exact model record, not only an efficiency class.
02Real use can differ from standard test conditions.
