Quick answer
How much does a refrigerator cost to run?
A typical refrigerator uses about 500 kWh/year and costs about $93/year at the EIA 2026-03 U.S. residential average of 18.56¢/kWh. Formula: 150W / 1000 x 24 hours/day x 365 days x electricity rate.
A refrigerator runs all year, so a small wattage difference becomes real money over a 10- to 15-year life. The best estimate uses annual kWh from the EnergyGuide label when available, then adjusts for age, temperature settings, garage heat, dirty coils, and door-gasket condition.

Refrigerator Cost Model: Annual kWh, Temperature Settings, Age, and Maintenance
A refrigerator runs all year, so a small wattage difference becomes real money over a 10- to 15-year life. The best estimate uses annual kWh from the EnergyGuide label when available, then adjusts for age, temperature settings, garage heat, dirty coils, and door-gasket condition.
| Scenario | Assumption | Annual kWh | Annual Cost | Monthly Avg |
|---|---|---|---|---|
| Current full-size model | 500 kWh/year EnergyGuide-style estimate | 500 | $93 | $8 |
| ENERGY STAR upgrade | 15% less energy than baseline | 425 | $79 | $7 |
| Old garage spare fridge | 850 kWh/year in hot or poorly ventilated space | 850 | $158 | $13 |
| Clean coils + good gasket | 8% runtime reduction from maintenance | 460 | $86 | $7 |
What Actually Drives Cost
- •Annual kWh from the yellow EnergyGuide label or product spec sheet
- •Temperature settings: about 37F for the refrigerator and 0F for the freezer are common efficiency targets
- •Age, compressor condition, condenser coil cleanliness, and door gasket seal
- •Location: garages, hot kitchens, and poor ventilation can raise runtime
- •Ice maker, water dispenser, second refrigerator use, and household door-open frequency
Common Bad Estimates
- !Estimating from instantaneous watts instead of annual kWh because compressors cycle on and off
- !Running an old spare refrigerator in a hot garage without checking yearly cost
- !Setting the refrigerator colder than needed and masking a bad door gasket or dirty coils
- !Comparing purchase price without adding lifetime electricity cost
Best Next Tests
- ✓Enter the EnergyGuide annual kWh if you have the label or model spec
- ✓Compare a new ENERGY STAR model against your current refrigerator over 10 years
- ✓Clean condenser coils and check door gaskets, then monitor runtime or plug-meter kWh
- ✓Model a garage refrigerator separately because hot ambient temperatures can change the bill
Energy Saving Opportunities
Save up to 15% vs standard models
~$37/year savings
Smart scheduling saves 10% more energy

Refrigerator Cost Summary
Refrigerator Energy FAQ
How much does it cost to run a Refrigerator per year?
A typical Refrigerator costs approximately $93 per year to run at the EIA 2026-03 US national average residential electricity rate of 18.56 cents per kWh. This assumes 24 hours of use per day for 365 days per year. Actual costs vary based on your local electricity rate and usage habits.
How much electricity does a Refrigerator use?
A Refrigerator uses approximately 150 watts of power. At typical usage of 24 hours/day, it consumes about 500 kWh per year. An ENERGY STAR certified model can reduce consumption by up to 15%.
What is the lifetime energy cost of a Refrigerator?
Over its average lifespan of 14 years, a Refrigerator costs approximately $910 in electricity at national average rates. This is in addition to the purchase price of approximately $1,200. Consider this total cost of ownership when purchasing.
How can I reduce my Refrigerator electricity costs?
To reduce Refrigerator energy costs: Set temperature to 37F fridge, 0F freezer. Clean condenser coils yearly. Keep it full for efficiency. Upgrading to an ENERGY STAR model can save $37/year. A smart version saves another $24/year through optimized scheduling.
How much electricity does a refrigerator use per year?
A full-size refrigerator often uses a few hundred kWh per year, but the exact value depends on size, age, compressor design, temperature settings, ice maker, and location. Use the EnergyGuide annual kWh label when you have it.
Does an old refrigerator use more electricity?
Often yes. Older refrigerators, worn gaskets, dirty coils, and hot garage placement can increase runtime. If a spare fridge runs all year, compare its annual kWh cost against replacing it or unplugging it when not needed.
What refrigerator temperature saves energy?
ENERGY STAR commonly recommends around 37F for the refrigerator and 0F for the freezer. Colder settings can increase runtime without improving food safety if the appliance is already holding proper temperature.
Methodology & Energy Data Sources — Refrigerator
Source reviewed May 25, 2026: EIA rate feed, DOE Energy Saver guidance, ENERGY STAR criteria, and appliance-specific assumptions.
How we calculate Refrigerator energy costs: Our calculations use EIA residential electricity price data, ENERGY STAR refrigerator guidance, EnergyGuide-style annual kWh assumptions, and 24/7 duty-cycle modeling. The model separates annual kWh, temperature settings, age, garage placement, and maintenance factors.
- Wattage (150W): Nameplate wattage from ENERGY STAR certified product database. Actual consumption may vary ±15% based on usage patterns and age of appliance.
- Annual kWh (500 kWh): Calculated as (Wattage x Avg Hours/Day x Avg Days/Year) / 1,000. Usage hours based on RECS (Residential Energy Consumption Survey) typical usage patterns for Kitchen equipment.
- Annual cost ($93): Calculated using the live EIA 2026-03 U.S. residential average electricity rate of 18.56¢/kWh. State-level rates are loaded from the same EIA data feed.
- Lifetime energy cost ($1,302): Projects 500 kWh/year × 14-year lifespan at the current national average rate. Use the state selector for a local-rate version.
- Carbon footprint (0.36 metric tons CO2e/year): Uses EPA eGRID national average emission factors. Regional factors vary significantly, so check EPA eGRID subregion data for local estimates.
