What it does
Calculate what an appliance costs to run: watts × hours/day × your kWh rate. Defaults to the US 2026 average residential rate (~$0.17/kWh per EIA). Includes presets for common appliances so you can sanity-check "is my space heater really $1.50/day?" without reading the spec sticker.

Frequently asked questions
- Where's my kWh rate?
- Look at your most recent electric bill — the 'energy charge', 'supply rate', or 'usage' line, divided by kWh consumed. Most US residential rates land between $0.08 (low: ID, WA, LA) and $0.40+ (high: HI, CA, MA).
- Does this include fixed monthly fees?
- No. Most utilities charge a fixed customer/connection fee per month independent of usage (typically $5–$25). This calculator estimates the variable cost only. Add the fixed fee separately for a full bill estimate.
