This is an estimate. Actual rates and usage vary by utility and appliance. Everything runs locally in your browser.
A clear schedule, not a surprise bill.
Define your TOU periods
Set the start hour, end hour and rate for each period — off-peak, standard and peak. Add or remove periods to match your utility tariff.
Add your appliances
Choose from 18 common presets or enter custom wattage. Set when each appliance runs and for how long.
See the cost and shift
Read the daily, weekly and monthly totals. Each appliance shows its cost breakdown and whether shifting the start time saves money.
What this estimate assumes
This calculator models a simple time-of-use tariff: each hour of the day belongs to one rate period, and each appliance runs a fixed number of consecutive hours starting at a chosen time.
The shift suggestion finds the cheapest consecutive block of hours for each appliance's duration. Real utilities may add demand charges, seasonal tiers, minimum bills, taxes or connection fees this tool does not model.
The result is an estimate for planning and comparison, not an invoice. Your utility bill is the authority and may differ. Everything runs locally — nothing you type leaves your browser.
The formula
Energy per hour = appliance watts / 1000
Cost per appliance = sum of (energy × rate) for each scheduled hour
Shifted savings = current cost − cheapest consecutive block cost
Worked example: a 500W washing machine running 1 hour at 9 AM (standard rate $0.14/kWh) costs $0.07. Moving it to 5 AM (off-peak $0.08/kWh) costs $0.04, saving $0.03/day or $0.78/month on a 5-day week.
