How to lower the cost of running a microwave

The power rating on the front of a microwave (e.g. 900W or 1,000W) is its cooking output; the draw from the wall is higher, usually 1,000–1,500W. Because it heats food directly and runs for minutes at a time, a microwave is one of the cheapest ways to cook or reheat. Our default assumes 15 minutes a day — adjust the hours to match how you cook.

  • Reheat in the microwave instead of the oven — it can use up to 80% less energy for small portions.
  • Unplug models with clocks you don't use to avoid a few watts of standby power.
  • Cover food so it heats faster and more evenly.
