What is a water usage calculator?
It estimates a water bill from monthly gallons, the water rate, sewer charges, base fees, stormwater fees, taxes, and billing assumptions.
Water usage index
Water bill calculators by monthly gallons used.

FAQ
Short answers for search visitors and bill-checking moments.
How do I estimate a water bill from gallons?
Divide gallons by 1,000, multiply by the usage rate, then add base fees, sewer fees, stormwater fees, taxes, and local charges.
Why is the bill higher than gallons times the rate?
Most water bills include fixed base fees, sewer charges, stormwater fees, minimum bills, or other local charges.
Which gallon page should I choose?
Choose the page closest to the usage shown on your bill, then edit the gallons and rate inside the calculator.
How do I know whether my water usage is normal?
Compare gallons per billing day, not only the total gallons. Then check household size, irrigation, guests, leaks, and whether the bill covered more service days.
