Use the result well
Estimate energy use from actual operating power and hours. Enter your own tariff; this is not a national average or a complete utility bill.
Start by replacing the example inputs with your own figures. Keep currency, quantity units and time periods consistent. Change one input at a time to understand what causes a difference. You can reset the fields, copy the result or share a link containing the inputs you choose.
Assumptions and limits
Enter average operating power, not necessarily maximum rated power. The tariff is supplied by you. Fixed charges, tiered pricing, generator subscriptions and taxes are excluded.
Compare a second scenario
Keep a copy of your first result. Change one relevant value, such as the rate, duration, amount or consumption. Compare both the headline answer and the breakdown. A smaller monthly amount does not necessarily mean a smaller total cost.
Your information
Calculations are processed to return a result; we do not store the submitted financial values in a profile or send them to analytics. A shared scenario link includes the values you explicitly choose to share. These estimates are informational and do not replace an agreement, official bill or professional assessment.
