FAQ

In Knoxville, sewer is billed in tiers based on usage, so the rate per gallon changes with volume. Our estimate uses the rate structure from KUB – Wastewater Rates (effective Jul 2025, inside city) 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.
