Energy Usage Calculator
Add devices or loads to estimate daily, monthly, and annual energy use and cost under flat, tiered, and time-of-use rate structures.

Flat rate
Delivery add-on and fixed fee apply to all three rate structures below, so you can compare them fairly.
Tiered (block) rate
Applies once your monthly usage crosses the threshold — usage up to the threshold is billed at the first rate, and anything above it at the second rate.
Time-of-use rate
Add one row per pricing period (e.g. summer/winter, weekday/weekend). Each row defines a date range, the on-peak time window within that range, and the on-peak / off-peak rates that apply. Usage is assumed to spread evenly across the day within each period.
Date ranges should ideally cover the full year without gaps or overlaps for an accurate annual total — total days covered: 0 / 365.
