Why should I separate electric and water usage?
Electric and water bills use different units and rate structures. Separating kWh from gallons makes it easier to see which bill changed and which detailed calculator to open next.
Can this replace my actual utility bill?
No. This is a planning estimate. Your utility bill is still the source of truth for local rates, taxes, riders, minimum charges, and billing rules.
