Refrigerator electricity cost in 2026: what you actually pay.
A modern 20 cu-ft top-freezer fridge consumes ~365 kWh/year — about $64 at the US average rate. A 25-year-old side-by-side can hit 1,500 kWh/year — $263. The fridge is the only appliance running 24/7, so age and efficiency matter more here than anywhere else.
2026 fridge electricity cost by type
| Type | Size | kWh/yr (Energy Star) | $/yr @ $0.175 |
|---|---|---|---|
| Compact / mini | 3–5 cu ft | 220 | $39 |
| Top freezer | 18–22 cu ft | 340–390 | $60–$68 |
| Bottom freezer | 20–24 cu ft | 450–520 | $79–$91 |
| Side-by-side | 22–28 cu ft | 580–680 | $101–$119 |
| French door | 24–28 cu ft | 500–620 | $88–$109 |
| Counter-depth French door | 20–23 cu ft | 540–640 | $95–$112 |
Old vs new: when replacement pays back
The DOE Energy Star database tracks fridge efficiency across decades. A typical comparison for a 22 cu-ft refrigerator:
| Year of manufacture | kWh/yr | Annual cost |
|---|---|---|
| 1990 | 1,400 | $245 |
| 2000 | 850 | $149 |
| 2010 | 580 | $102 |
| 2018 | 430 | $75 |
| 2025 Energy Star | 360 | $63 |
Payback math for replacing a 1990 fridge with a 2025 Energy Star one ($1,200 retail): $245 − $63 = $182/yr saved → 6.6-year payback on electricity alone. The freezer-only "garage spare" from the 1990s plugged in for "extra space" is the most expensive piece of furniture in your house.
A pre-2005 fridge vs a 2025 Energy Star one — does it pay back?
Inputs from the table above: a year-2000 22 cu-ft fridge pulls 850 kWh/yr; a 2025 Energy Star model of the same size pulls 360 kWh/yr. One rate throughout — the 2026 US average of $0.175/kWh — so every number here matches the table.
| Pre-2005 fridge — 850 kWh × $0.175 | $149 / yr |
| 2025 Energy Star — 360 kWh × $0.175 | $63 / yr |
| Energy saved — 490 kWh × $0.175 | $86 / yr |

What the same fridge costs by state
The $0.175/kWh used above is a national average that almost nobody pays exactly. Residential rates in 2026 run from 12.35¢/kWh in North Dakota to 46.62¢/kWh in Hawaii (EIA residential rate data) — a 3.8× spread. Same fridge, same kWh, a very different bill. Every number below uses one formula: annual cost = kWh/yr × state rate, with 365 kWh for a new Energy Star top-freezer (the intro assumption) and 1,400 kWh for a 1990s unit.
| State | Rate (¢/kWh) | New fridge, 365 kWh | 1990s fridge, 1,400 kWh |
|---|---|---|---|
| 10 cheapest states | |||
| North Dakota | 12.35 | $45 | $173 |
| Idaho | 12.70 | $46 | $178 |
| Nebraska | 13.28 | $48 | $186 |
| Utah | 13.29 | $49 | $186 |
| Oklahoma | 13.31 | $49 | $186 |
| Iowa | 13.86 | $51 | $194 |
| Montana | 13.90 | $51 | $195 |
| Missouri | 14.01 | $51 | $196 |
| Arkansas | 14.16 | $52 | $198 |
| Nevada | 14.29 | $52 | $200 |
| 10 most expensive states | |||
| Hawaii | 46.62 | $170 | $653 |
| California | 35.25 | $129 | $494 |
| Connecticut | 32.24 | $118 | $451 |
| Massachusetts | 29.45 | $107 | $412 |
| New York | 29.45 | $107 | $412 |
| Maine | 28.42 | $104 | $398 |
| Rhode Island | 28.30 | $103 | $396 |
| Alaska | 27.35 | $100 | $383 |
| New Hampshire | 27.24 | $99 | $381 |
| Vermont | 24.56 | $90 | $344 |
Two things fall out of this table. First, a new fridge is cheap to run everywhere — even Hawaii's $170/yr is under $15/month. Second, the 1990s unit is where geography bites: $653/yr in Hawaii is more than half the price of a brand-new fridge, paid every year. That changes the replace-or-keep verdicts above. A 1990s clunker (1,400 kWh) replaced by a 2025 Energy Star model (360 kWh) saves 1,040 kWh/yr, so payback on a $1,200 fridge is $1,200 ÷ (1,040 kWh × rate): about 2.5 years in Hawaii, 9.4 years in North Dakota — under ten years in all 50 states. A merely-old year-2000 fridge (850 kWh, saving 490 kWh/yr) is a different story: it only pays back inside 10 years where rates are above roughly 24.5¢/kWh, which in 2026 means exactly ten states — Hawaii, California, Connecticut, Massachusetts, New York, Maine, Rhode Island, Alaska, New Hampshire and Vermont. Everywhere else, keep it until it dies.
The same garage fridge in Connecticut vs Idaho
One year-2000 spare fridge, 850 kWh/yr, running 24/7 in a garage. Only the state changes. Rates are 2026 EIA residential averages: Connecticut 32.24¢/kWh, Idaho 12.70¢/kWh. Formula: 850 kWh × rate.
| Connecticut — 850 kWh × $0.3224 | $274 / yr |
| Idaho — 850 kWh × $0.1270 | $108 / yr |
| Ten years in Connecticut | $2,740 |
| Ten years in Idaho | $1,080 |
Not in either state? Put 850 kWh and your own rate into the electricity cost calculator — it takes 20 seconds.
6 ways to cut fridge electricity
- Set fridge to 37 °F / freezer to 0 °F. Each degree colder = 4–6% more energy.
- Vacuum the condenser coils annually. Dusty coils raise energy use 10–25%.
- Keep it full but not packed. Cold mass holds temperature; airflow can't be blocked.
- Check door gaskets. If a dollar bill slides out when closed, replace the seal ($25).
- Skip the ice/water dispenser model if not essential — those models use 14–20% more.
- Unplug the garage backup fridge. Especially if it's pre-2005.
Replace your old fridge, or keep it?
Replace it if…
- It's a true 1990s unit (~1,400 kWh/yr) — payback is ~6.6 years and only gets better at high rates.
- It's the pre-2005 "garage spare" running 24/7 for a few drinks — unplug or scrap it; that's $149/yr for almost nothing.
- Your rate is well above $0.175/kWh, which shortens every payback above.
- It's failing anyway — then buy the most efficient model that fits, not like-for-like.
Keep it if…
- It's a working post-2010 fridge (~580 kWh or better) — the gap to a new one is too small to justify $1,200.
- It's a year-2000-era model (850 kWh) you actually use daily — ~14-year payback means it's not worth scrapping for power alone.
- Your rate is below $0.13/kWh and the fridge is post-2000 — cheap power stretches that payback past 20 years (a true 1990s clunker still pays back in under 10 even there).
- You'd only replace it for the energy savings — buy a new fridge for the kitchen, not the bill.
5 mistakes that skew fridge-cost math
- Pricing at the national average. Rates span 12.35¢ (North Dakota) to 46.62¢/kWh (Hawaii) — a 3.8× spread. A payback that looks like 14 years at $0.175 is 7 years in New England and 20+ years in the Plains states. Always run your own rate; it's the top line of your bill.
- Multiplying nameplate watts × 24 hours. The compressor cycles on and off; a fridge that draws 150 W while running does not draw 150 W around the clock. That method overestimates by roughly 3×. Use the Energy Guide annual kWh instead — it already includes duty cycle and defrost.
- Treating the old fridge as free because "it's already paid for." The purchase price is sunk either way; the running cost isn't. A 1990s spare costs $173–$653/yr depending on state — that's the number to judge, not the $0 you'd spend to keep it.
- Comparing against zero instead of the forced replacement. A 20-plus-year-old fridge will die soon regardless. The honest comparison isn't "$1,200 vs nothing" — it's "buy now and start saving vs buy in two years anyway and burn $300–$1,300 of electricity waiting."
- Ignoring where the fridge lives. A compressor fights the temperature gap between inside and outside the box. A spare in a hot summer garage faces a much bigger gap than one in a 70 °F kitchen, so its Energy Guide number — measured in a controlled room — understates what you'll actually pay in July.
Test your fridge in the calculator
Pull your fridge's annual kWh from the yellow Energy Guide sticker (or look up the model on energystar.gov). Plug it into the electricity calculator with your real rate.
Frequently asked questions
How can I find the wattage of my fridge?
Check the nameplate inside the door or on the back: it'll list voltage and amps (compressor running) or watts directly. Multiply V × A for watts. The yellow Energy Guide label gives annual kWh — the most useful number.
Is a smart Wi-Fi fridge worth the energy hit?
No. The compressor doesn't care; the touchscreen and Wi-Fi module add ~25–40 kWh/year ($4–$7). Not deal-breaking but never advertised. The real cost is the $600–$1,200 premium over a non-smart equivalent.
Does an empty fridge use less electricity?
Slightly. Full fridges hold cold mass better against door openings, but the compressor's job is mostly fighting heat infiltration through walls and gaskets — which doesn't depend on contents. Difference is <5%.
How much does a second garage fridge cost per year?
A typical year-2000 spare pulls ~850 kWh/yr. At 2026 residential rates that's roughly $108/yr in Idaho, $149 at the US average, and $274/yr in Connecticut — usually to chill a case of drinks. If it's a 1990s unit, roughly double those figures. Unplugging it is the highest-yield move in this whole guide.
Can I estimate fridge cost from nameplate watts × 24 hours?
No — that overestimates by roughly 3×. The compressor cycles on and off, so a fridge with a 150 W running draw doesn't consume 150 W around the clock. Use the annual kWh on the yellow Energy Guide label (or the model's energystar.gov listing) and multiply by your rate; that number already accounts for duty cycle and defrost.
Why does the replace-or-keep answer change by state?
Because the savings are kWh saved × your rate, while the new fridge costs the same ~$1,200 everywhere. Replacing a year-2000 fridge saves about 490 kWh/yr: at Hawaii's 46.62¢/kWh that's ~$228/yr and a 5–6 year payback; at North Dakota's 12.35¢ it's ~$61/yr and a ~20-year payback — longer than the fridge will live. Same appliance, opposite verdict.
