Municipal tiers and minimum charges vary widely. Copy the rates and units from your local tariff or bill.

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.
