What these labels mean

  • Confirmed — From this area's rate schedule.
  • Benchmark — From an official typical (e.g. state commission 1,000 kWh); not city-specific.
  • Delivery only — Regulated delivery charges only (e.g. Texas); supply varies by plan.
  • Supply vs delivery (MA) — Electric supply ($/kWh) is the generation portion; delivery is wires, transmission, and programs from Eversource or National Grid. Municipal aggregation (e.g. Boston, Cambridge) replaces only the supply price.
  • Estimated — From other or incomplete sources; use as a rough guide.

FAQ

In Cambridge, sewer is billed in tiers based on usage, so the rate per gallon changes with volume. Our estimate uses the rate structure from City of Cambridge – FY25 Water & Sewer Rates 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. Massachusetts splits electric into regulated delivery (Eversource or National Grid) and supply (Basic Service, municipal aggregation like Boston/Cambridge, or a competitive supplier). We show supply and delivery separately when data allows; totals use 1,000 kWh for comparison.
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.
