Calculation logicFrequently asked questions
How do I compare two scenarios?
Enter watts, hours, and rate for each. Identical math isolates the decision to behavior or equipment.
What should I hold constant?
Rate and days per week. Change one variable at a time for honest comparisons.
Can I compare fuels?
Convert each to cost per unit of service, like dollars per hot shower or per mile, before comparing.
Why show both kWh and dollars?
kWh reveals efficiency; dollars reveal the bill. Efficient but heavily used gear can still cost more.
