Household ledger
Add what you own, set the hours, and see a ranked ledger priced at your rate. Reconcile with a real bill, then find which upgrades pay back first. Everything is stored in this browser — no account needed.
Rates use the EIA residential average for July 2026, or your own custom rate. See the method.

They are planning estimates, not billing figures. Utility tiers, time-of-use windows, taxes and fees can move the real total. Use the bill reconciliation card to see how much of your actual usage the ledger explains.
