How it works
- Prices and hours come straight from each utility's rate schedules and plan pages, with the date we last checked them.
- Calculators apply those prices to every hour of a typical month, using your monthly use and a daily routine you choose.
- Everything is an estimate. Read how we calculate for the formulas and assumptions.
