Refrigerator Running Cost Calculator

Look at the yellow EnergyGuide label on the fridge or its product listing, where it shows "estimated yearly energy use" in kWh. Most retail and manufacturer spec pages list this figure too. If you can't find it, a typical modern fridge runs about 350-450 kWh per year, so 400 is a safe placeholder.

A typical modern refrigerator uses roughly 350-450 kWh per year. Older units, especially anything 10-15+ years old, often draw 700-1200 kWh per year, which is why upgrading can noticeably cut the bill. Bigger French-door and side-by-side models with ice and water dispensers tend to sit at the higher end of the modern range.

It's only as accurate as the two numbers you put in. The kWh figure comes from standardized manufacturer testing, and your real-world use can vary with kitchen temperature, how often the door opens, and how full the fridge is. Your actual electricity rate may also differ from the state default, so check a recent bill for the exact dollars-per-kWh. The calculation itself is exact arithmetic, not a lab measurement.

Start by choosing a model with a lower kWh rating, since that number drives the whole cost. Keep the fridge a few inches from the wall for airflow, clean the condenser coils, and set it to the recommended temperature rather than colder than needed. If your current fridge is an older 700-1200 kWh unit, the yearly savings from a modern 350-450 kWh model often justify replacing it.

Not by itself. Running cost is one factor, but capacity, layout, reliability, and purchase price matter too. Use this number to compare similar models head-to-head, then weigh it against what the fridge actually costs upfront and how well it fits your kitchen and needs.
