PeakGrid turns watts and hours into money. Check what your AC, dryer, or EV charger really costs per month, and how much shifting to off-peak hours could save.
Check my appliance costsPick an appliance or enter your own wattage, add your electricity rate, and see the real running cost per day, month, and year.
Typical central AC: 3,000 to 5,000 W. Compressors cycle, so 6 to 10 runtime hours on a hot day is common.
Wattages shown are typical published ranges, not exact figures for your model. Rate examples for illustration only: 0.12, 0.17, 0.30 per kWh. Your utility bill shows your real rate and currency.
Enter your off-peak rate to estimate savings. If your utility offers time-of-use pricing, flexible loads like laundry, dishwashing, and EV charging are the easiest to move.
