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.

Who bills you

Only the utilities indexed so far appear here.

Your rate plan

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

Electricity used each month

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.

Sales or utility tax

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

What you actually paid last year

Optional. If you enter it, the gap against the published tariff is shown — that gap is where riders, local taxes and meter-read timing live.

Include fixed monthly charges

Turn off to compare energy charges alone.

How this was worked out5 assumptions, 3 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 because no hourly readings were supplied. A typical household uses more during afternoon peak hours, so a time-of-use bill is likely higher than this estimate.Real bill likely higher
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 September 2, 2026.

Indexed so far: 450 tariffs from 45 utilities. A pilot snapshot, not national coverage. Utilities are discovered by probing population-centre coordinates in 18 states, because URDB cannot be queried by utility or by address. A provider outside every probed territory — most rural cooperatives — will not appear here yet.
