How It Works
Many utilities charge different rates at different times of day. Enter your peak and off-peak usage and rates to find your total bill and identify potential savings from shifting usage.
Formula
Bill = (Peak kWh x Peak Rate) + (Off-Peak kWh x Off-Peak Rate)
Frequently Asked Questions
What are peak hours?
Peak hours are typically weekday afternoons (3-9 PM) when grid demand is highest. Off-peak includes nights, weekends, and early mornings. Check your utility for exact times.
How much can I save with TOU?
By shifting heavy loads (laundry, dishwasher, EV charging) to off-peak hours, households can save 10-30% on electricity bills with TOU pricing.
