Planning estimate. Your utility’s tariff, taxes, tiers and adjustments control the actual bill.
FORMULA
Cost = input kW × runtime × days × price per kWhIMPORTANT LIMIT
Compressors cycle on and off. Use average measured input when possible, not only the maximum label rating.
HOW TO USE IT
Copy the bill’s units first.
Match every field to the unit printed on your statement. Use the current billing period, preserve fixed charges, and compare a similar number of service days.
For a stronger estimate
- Use the exact rate from your bill instead of a reference average.
- Keep taxes, credits and past-due balances separate.
- Check tiers or time-of-use windows in the utility tariff.
