New, extra energy-efficient home equipment might value you on the register, however the financial savings are likely to catch up over time. Most individuals consider warmth pumps or photo voltaic panels once they hear “long-term energy-saving funding,” however your fridge quietly makes the identical case.
Newer fashions use significantly much less electrical energy than these from even 10 years in the past, and that hole in power use interprets immediately into decrease utility payments.
I needed to place an precise quantity on it, so I did a ton of math, analyzing 2,630 fridges and their Vitality Star information to match right now’s fashions to these from 2016. (Whereas I did not calculate the power delta for fridges older than 2016, it is virtually actually higher.)
This is how a lot power and cash you might save by making the change.
The place my fridge information comes from
Publicly out there Vitality Star information is a serious participant on this evaluation.
For my 2025 samples, I analyzed power utilization in fashionable Vitality Star-certified fashions. For 2016, I could not depend on Vitality Star information as a result of it lists solely fashions that meet the newest requirements, not earlier ones.
As a substitute, I sourced my 2016 information from the California Vitality Fee’s Modernized Equipment Effectivity Database System. Slightly than cowl 42 fridge courses individually, I grouped them into the next broad classes:

I did not have a look at standalone fridges as a result of there wasn’t sufficient information from both pattern group to carry out a significant comparability. Standalone freezers are a unique Vitality Star dataset that I did not embody.
It was important to exclude older merchandise from the fashionable information
I excluded any fridges manufactured earlier than 2021.
The present slate of Vitality Star-qualified fridges contains fashions relationship again to January 2014, so I narrowed my checklist of candidates to merchandise that hit the market in 2021 or later — the final time Vitality Star up to date its standards. Whereas this technically implies that this is not a one-to-one comparability of 2025 and 2016, it displays vital particulars:
- Shops do not solely carry fridges from the present calendar 12 months, so the information ought to at the very least mirror what’s out there at retail.
- Lots of the best fridges had been launched earlier than 2025.
- It is solely attainable {that a} fridge rolled off the manufacturing facility line a month in the past, regardless of incomes a certification in 2021.
Evaluating your current fridge
I counsel utilizing Vitality Star’s Flip Your Fridge Calculator to match your present fridge with this evaluation. It offers a tough estimate primarily based in your fridge’s age, measurement, configuration and native electrical energy worth. For extra present electrical energy costs, verify your latest billing assertion.
Likewise, you may search for an Vitality Information Label along with your fridge’s mannequin quantity for a precise yearly electrical energy use determine. I take advantage of the newest Vitality Info Administration information from 2024 for my calculations — 2025’s information is not finalized as of the publishing of this text. It lists the residential nationwide common at $0.1648 per kilowatt-hour.
The magic quantity for every sort of fridge
As a result of all of it boils right down to a fridge’s class and quantity, I am unable to offer you a common quantity that applies to each fridge. As a substitute, I will break down the highlights and common stats in every class. Discovering retail pricing from 2016 (and 2025) proved to be a way more tough activity than I might resolve within the time I had for this evaluation. As a substitute, I used the information to create easy power financial savings pointers under.
Fridges with probably the most potential financial savings over 10 years
Vitality-efficient side-by-side fridges yield probably the most financial savings, in keeping with my calculations.
If the added value of upgrading to a brand new fridge (in contrast with shopping for or repairing a used one) is decrease than the numbers under, the brand new fridge will doubtless offset that worth distinction by way of power financial savings alone over the subsequent 10 years:
- Aspect-by-side fridges: $340
- Backside freezers: $272
- Prime freezers: $83
- Compact fridges: $0 (common power effectivity stays largely unchanged since 2016)
If a brand new fridge prices greater than this effectivity premium, it is going to take longer to interrupt even. Do not forget that whereas averages can provide you a very good rule of thumb, probably the most environment friendly home equipment will save much more in power prices. These numbers additionally do not account for potential rebates out of your utility firm, so precise financial savings could also be even greater.
Crucially, these numbers assume you are not switching to a unique fridge sort. For instance, you may doubtless see even higher power financial savings when changing a side-by-side fridge with a bottom-freezer fridge.
Key takeaways
- New side-by-side fridges will, on common, reduce your power prices greater than another sort of fridge, although backside freezers additionally noticed some good enhancements over the past 10 years. Upgrading both sort of fridge to a contemporary model might be value it.
- The $83 in power financial savings for high freezers over 10 years most likely will not be sufficient to justify an improve in case your current high freezer nonetheless works.
- Fashionable compact fridge know-how is basically similar to that of 2016. You do not have to be choosy with most fashions.
A brand new top-mounted fridge might save simply $83 in electrical energy over 10 years.

- 121 minifridge fashions (81%) from 2016 meet fashionable Vitality Star standards.
- Roughly 5% of fashions from each pattern teams qualify for Vitality Star Most Environment friendly 2025.
The place you reside additionally performs a task
Your regional power prices can swing the financial savings in both route.
Electrical energy prices range broadly relying on the state and area you reside in. For instance, North Dakota’s common worth in 2024 was simply 11.51 cents per kilowatt-hour (the bottom within the US), whereas Hawaii’s was a whopping 42.86 cents.
The upper your electrical fee, the extra you may save on power with a brand new fridge. In contrast with the nationwide common, residents of Hawaii, California, Massachusetts, Connecticut, Rhode Island and Alaska will see further power financial savings of 51% to 160% when shopping for a brand new Vitality Star fridge.
Conversely, financial savings shall be a lot decrease in states with comparatively low cost electrical energy, resembling North Dakota, Idaho, Nebraska, Louisiana and Washington, which common lower than 12 cents per kilowatt-hour. In North Dakota’s case, that is simply $237.51 in financial savings on a side-by-side fridge — $102.56 lower than the nationwide common.
Effectivity math would not add up for good fridges
The exorbitant upfront value of most premium good fridges will doubtless cancel out your power financial savings.
Whereas I do not explicitly discover it on this evaluation, good fridges aren’t typically a very good funding in case your essential objective is saving power over time. It has nothing to do with power effectivity and every thing to do with the premium you are paying for good dwelling tech.
For instance, Samsung’s good fridge fashions value at the very least $700 greater than their conventional counterparts — this simply obliterates any long-term power financial savings. That stated, good fridges aren’t going away, and it is OK to splurge in case your price range permits.
How I did the mathematics: Calculating effectivity information for fridges from 2016
Calculating fridge effectivity was a serious enterprise.
Once I began this evaluation, I had no thought how bewildering refrigerator-efficiency rules are within the US. However I wanted to grasp them to precisely calculate 2025 energy-efficiency values for all of the 2016 fashions.
The only strategy to clarify that is that each attainable fridge configuration makes use of a novel system decided by effectivity variables, the fridge’s adjusted quantity, and anticipated base power consumption.
For instance, Class 3 Fridges have a top-mounted freezer, automated defrost, and do not embody an automated icemaker. As a result of the freezer is on high, the equipment’s fan can make the most of the truth that chilly air sinks to drag air from the freezer into the fridge compartment. One of these passive cooling will all the time be extra environment friendly than pumping chilly air up from a bottom-mounted freezer.
Likewise, the adjusted quantity accounts for the freezer compartment, which takes extra power to achieve a goal temperature than the recent meals compartment. Adjusted quantity is all the time bigger than the linear quantity of a fridge — at the very least when the equipment has each a freezer and a fridge.
Lastly, the entire elements of a fridge have a baseline power stage (base load) decided by the legal guidelines of physics. Since fridges cannot use lower than this a lot power, it is added to the ultimate calculation:
(Effectivity variable X Adjusted Quantity) + Base Load = Most Allowable Vitality Use
When you notice that just about every thing — from defrost sort to freezer location to built-in versus freestanding — impacts effectivity, it is smart that there are 42 courses of fridges and freezers with totally different power effectivity requirements.
Vitality Star standards are extra simple
Vitality Star has a number of rankings for dwelling home equipment.
It is a lot simpler to calculate the power stage a fridge must qualify for an Vitality Star Certification. It merely wants to make use of 10% much less power than the federal normal — I excluded fashionable fridges that fall under this threshold. The final wrinkle is the Vitality Star Most Environment friendly standing, which modifications yearly. Listed below are the 2025 requirements (PDF):
- Prime-mounted freezers should have an annual power consumption of 637 kWh or much less.
- Backside-mounted freezers and side-by-side items should be at the very least 27% extra environment friendly than the federal normal.
- Compact fridges should be at the very least 30% extra environment friendly than the federal normal.
As soon as I discovered the calculations for every fridge class, it was merely a matter of including the formulation to my spreadsheet, calculating common power prices and figuring out the financial savings.
