How this service works
Appliance electricity running-cost calculator — exact running cost at local electricity rates with an efficiency upgrade comparison. For homeowner and energy agents.
Output
Returns the exact annual running cost of the specified appliance at local retail electricity rates for the given state, plus a side-by-side upgrade comparison showing cost of a more efficient model and estimated annual savings.
Example use cases
Compare old versus new dryer costs
“I've got this ancient clothes dryer that's probably eating up my electric bill. Can you figure out what it actually costs me to run every year here in Ohio, and show me how much I'd save if I switched to a newer Energy Star model?”
Evaluate window AC unit upgrade savings
“My bedroom window air conditioner is from 2005 and super loud. What am I spending annually to keep it running in Florida humidity, and is upgrading to a modern unit going to be worth the investment?”
Calculate monthly hot water heater expenses
“We're trying to cut costs and I want to understand our electric water heater situation. What's the real annual cost to run our current unit at our local rates here in Washington State, and could we actually save meaningful money by switching to a high-efficiency model?”

Use this endpoint when a homeowner or energy agent needs a precise, localized running-cost figure for a specific appliance and wants to see whether upgrading to a more efficient model is financially worthwhile. Prefer this over generic energy calculators when local electricity rate accuracy and upgrade ROI comparison are both required in a single call.
Side effects
- Unknown appliance type returns error or empty result
- Invalid or unsupported state/location returns rate lookup failure
- Missing wattage or usage hours causes incomplete cost calculation
- Electricity rate data unavailable for a given region
- Upgrade comparison unavailable for niche appliance categories
