The layout and size of a fridge change what it costs to run more than almost anything else. Here are the medians for ENERGY STAR certified full-size models in the EPA database, at 18.16¢ per kWh.
| Type | Models | Median energy | Yearly cost | 10-year cost |
|---|---|---|---|---|
| Top Freezer | 742 | 363 kWh | $66 | $659 |
| Bottom Freezer | 1,516 | 563 kWh | $102 | $1,022 |
| Side-by-Side | 119 | 640 kWh | $116 | $1,162 |
| Freezerless and Single Door | 277 | 289 kWh | $52 | $525 |
| Compact Refrigerator | 1,688 | 246 kWh | $45 | $447 |
| Total capacity | Models | Median energy | Yearly cost |
|---|---|---|---|
| Under 18 cu ft | 1,044 | 360 kWh | $65 |
| 18 to 22 cu ft | 910 | 465 kWh | $84 |
| 22 to 26 cu ft | 384 | 615 kWh | $112 |
| 26 to 30 cu ft | 266 | 715 kWh | $130 |
| 30 cu ft and up | 50 | 714 kWh | $130 |
This matches ENERGY STAR's buying advice: larger fridges generally use more energy, models with the freezer on top tend to use the least, and fewer doors reduce air leakage. ENERGY STAR also says the most energy-efficient models are typically 16 to 20 cubic feet.
Medians hide a wide spread. Within each type and size band, our rankings show which models cost the least to run. Lowest running cost is not always the best value, so weigh price and features too.
