FAQ

In Flower Mound, electric is deregulated: you choose a retail electric provider (REP) for supply, while the transmission and distribution utility (TDU) delivers power. Our estimate uses regulated delivery charges plus a typical supply rate so you can compare total utility costs. Your actual supply rate depends on the plan you choose.
In Flower Mound, sewer is billed in tiers based on usage, so the rate per gallon changes with volume. Our estimate uses the rate structure from Town of Flower Mound – FY2025-26 residential sewer (effective Oct 1, 2025) at the assumed 5,000 gallons per month. Your bill will vary with actual usage.
We use base charges and per-unit rates from official provider pages. Electric = base + (rate × assumed kWh). Water = base + (rate per 1,000 gal × assumed gallons / 1,000). Sewer is either a flat fee or a percentage of water. Trash is a fixed monthly fee. See the Methodology page for full formulas.
Actual bills depend on your usage, seasonal rates, taxes, fees, and provider-specific rules. Our estimates use fixed assumed usage (e.g., 1,000 kWh, 5,000 gal) for comparison. Your home may use more or less.
Each component shows a 'last verified' date. We aim to update from official sources periodically; always confirm current rates on the provider's site before making decisions.
