Bill Analyzer

Enter what you use and pick a published tariff. This prices the whole year against the real rate structure — tier bands, time-of-use periods, fixed charges and all — and shows the working.

Alphabetical. Only the utilities indexed so far appear here.

Plans that cannot be priced stay listed, disabled, rather than disappearing.

One number for every month, or twelve separated by commas if you have a year of bills. Seasonal figures are worth entering: they change which tier bands you reach.

Leave at 0 if you do not know it. Most US jurisdictions add one, so 0 understates a real bill.

Turn off to compare energy charges alone.

How this was worked out5 assumptions, 2 that could move the total
  • Priced against the 2026 calendar. Weekday and weekend day counts differ between years, which moves the total on a time-of-use tariff.No effect on the total
  • Weekend rates are applied on Saturday and Sunday. URDB publishes no holiday calendar, so utilities that bill public holidays at weekend rates are not reflected.Effect unknown
  • Hours are local clock hours with no daylight-saving shift, matching how time-of-use periods are written in the tariff.No effect on the total
  • Monthly totals were spread evenly across every hour. This tariff prices every hour the same way, so the result is unaffected.No effect on the total
  • No sales or utility tax was applied. Most US jurisdictions add one, so a real bill will be higher.Real bill likely higher

Tariff data: NREL/OpenEI Utility Rate Database (CC0 1.0), retrieved October 8, 2026.

Indexed so far: 1211 tariffs from 217 utilities. Not every utility. Utilities are reached two ways: by probing population-centre coordinates in 18 states, and by fetching, by EIA number, the utilities that serve most of each state's homes according to EIA-861. A smaller utility outside both — many rural cooperatives and municipal utilities — will not appear here yet.
