Savings calculators

We have two ENERGY STAR® calculators that can help you find the savings you are looking for. These calculators will estimate energy, cost and emissions savings on your ENERGY STAR certified equipment. And they’re free to use!

National average energy costs are calculated and used as the calculators’ default settings. You can also localize the settings by selecting a province or territory, or input your own data.

ENERGY STAR® Simple Savings Calculator

The ENERGY STAR Simple Savings Calculator will show you how much money you can save and the environmental benefits of buying ENERGY STAR certified products. The calculator can compare this information on up to three models of a single type of product:

  • annual operating costs
  • lifecycle costs
  • payback periods
  • total energy savings
  • total cost savings

The ENERGY STAR Summary Calculator

This tool compares different types of products at one time! Use the Summary Calculator to assess savings from purchasing multiple types of ENERGY STAR certified products. The Summary Calculator is an add-on feature of the ENERGY STAR Simple Savings Calculator.
