Model
Hisense FV21C7H*E
Rank #528 means 527 of the 622 freezer models we track cost less to run each year; the 93rd efficiency percentile means it uses less energy for its size than 93% of those models.
What does the Hisense FV21C7H*E cost to run per year?
Rank #528 of 622 puts the Hisense FV21C7H*E among the pricier freezer models we track to keep running, at roughly $92 a year. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $102/yr to run, a saving of roughly $10 a year. Its size-adjusted efficiency percentile of 93 sits well above the class median, a clearly above-average efficiency result. This class has no published efficiency-factor figure beyond annual kWh itself, so at 21.2 cu ft (the class spans 1.1 to 23), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Hisense FV21C7BWE at $92/yr runs a little cheaper and the Hisense HFU210N6CVE at $92/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A freezer typically stays in service for somewhere around 14 years; over that span, the Hisense FV21C7H*E's $92/yr adds up to roughly $1288 in electricity alone, before purchase price or repairs.

By the numbers
The Hisense FV21C7H*E normalized against its whole class, so each figure means something.
What it costs you over time
Running cost is an every-year number, so it compounds. At $92/yr, here is what the Hisense FV21C7H*E adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Hisense FV21C7H*E costs about $920. That is roughly $100 less than a standard model in its class, which would run closer to $1020 over the same ten years.
How the Hisense FV21C7H*E compares
The freezer class we track runs from $25 to $120 a year. At $92/yr, it runs about $17 a year above the class median of $75, and it is about $67 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $102/yr, the Hisense FV21C7H*E uses 10% less energy.
What drives its running cost
At 21.2 cu ft, the Hisense FV21C7H*E is a large freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up.
- Interior volume. As with refrigerators, more cubic feet of frozen storage generally means a bigger compressor and a higher annual energy figure.
- Insulation and defrost type. Better-insulated cabinets lose less cold to the surrounding room, and frost-free (automatic-defrost) freezers run a periodic heating element that a manual-defrost model does not.
- Chest vs upright design. Door orientation affects how much cold air escapes per opening: top-opening chest designs generally hold cold better than front-opening upright ones.
Common questions
Is the Hisense FV21C7H*E cheap to run?
Its $92/yr running cost, rank #528 of 622, is above what most freezer models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Hisense FV21C7H*E cost per month?
About $7.64 a month, which is the $92 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 494 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $92 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Hisense FV21C7H*E for its size?
93rd percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
