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.
