How this service works
Total a list of appliances (watts, hours a day, quantity) into kWh and cost per day, month and year, with each one's share.
Output
Returns a structured object with total kWh and cost per day, month, and year for the entire household load, plus a per-appliance array showing each item's name, watts, hours/day, quantity, days/year, kWh per month, kWh per year, cost per year, and share percentage of total consumption. Also includes average watts and optional summary/disclaimer text.
Example use cases
Monthly bill estimate before moving
“I'm about to move into a new apartment and want to know what my electricity bill will look like. I'll have a fridge at 150W running all day, a washing machine at 500W for 1 hour daily, a laptop at 65W for 8 hours, and 8 LED bulbs at 9W for 6 hours. Electricity there is $0.15 per kWh — what will I pay per month?”
Identifying biggest energy hogs at home
“Which of my appliances is costing me the most? I run a central AC at 3500W for 8h/day, a water heater at 4000W for 2h/day, a fridge at 200W all day, and a TV at 120W for 5h/day. My electricity rate is $0.18 per kWh — give me the breakdown with each device's share of my total bill.”
Annual cost projection for home office setup
“I'm setting up a home office and want to know the yearly electricity cost. I'll have a desktop PC at 300W for 8h/day, two monitors at 40W each for 8h/day, a desk lamp at 12W for 8h/day, and a small space heater at 1500W for 3h/day on 120 days per year. Rate is $0.12 per kWh.”
Technical details
Endpoint
GEThttps://home-energy-calc.x402tookit.com/household-load?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to aggregate multiple appliances into a single household energy and cost summary with per-device breakdowns and share percentages. It is ideal for home energy audits, budget estimation, and consumption analysis across a full list of devices. Prefer it over a simple bill estimator when you have individual appliance data and want itemized attribution, not just a total kWh input.
Side effects
- Missing required 'appliances' query parameter returns an error
- Missing or zero 'pricePerKwh' returns an error (must be above 0)
- Malformed appliance string format (wrong delimiter or missing required fields) causes parse failure
- standbyWatts outside 0–2000 range may be rejected
- Appliance entries with zero or negative wattage may be flagged or ignored
