Model
Bosch B36FD51SN*
Rank #952 means 951 of the 1,000 refrigerator models we track cost less to run each year; the 63rd efficiency percentile means it uses less energy for its size than 63% of those models.
What does the Bosch B36FD51SN* cost to run per year?
Almost nothing we track in this class costs more to run than the Bosch B36FD51SN*: about $130 a year, rank #952 of 1,000. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $144/yr to run, a saving of roughly $14 a year. Adjusted for size, it is more efficient than 63% of refrigerator models we track, a solidly above-average result. It is a counter-depth model, built shallower to sit flush with kitchen cabinets, a design choice that typically trades away some interior volume (and so some running-cost headroom) for the built-in look.
Immediately around it on the leaderboard, the Bosch B36FD10EN* at $130/yr runs a little cheaper and the Samsung RF29DB9700** at $131/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A refrigerator typically stays in service for somewhere around 12 years; over that span, the Bosch B36FD51SN*'s $130/yr adds up to roughly $1560 in electricity alone, before purchase price or repairs.

By the numbers
The Bosch B36FD51SN* 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 $130/yr, here is what the Bosch B36FD51SN* adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Bosch B36FD51SN* costs about $1300. That is roughly $140 less than a standard model in its class, which would run closer to $1440 over the same ten years.
How the Bosch B36FD51SN* compares
The refrigerator class we track runs from $8 to $149 a year. At $130/yr, it runs about $66 a year above the class median of $64, and it is about $122 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $144/yr, the Bosch B36FD51SN* uses 11% less energy.
What drives its running cost
At 26.3 cu ft, the Bosch B36FD51SN* is a large refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, among refrigerator models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal.
- Counter depth vs standard depth. Counter-depth models sit flush with cabinets but usually hold less interior volume than a standard-depth model of the same width, which can nudge the per-cubic-foot running cost either way.
- Interior volume. Cubic feet of interior volume is the first thing that scales a fridge's running cost up or down, before compressor quality even enters the picture.
- Compressor technology. Newer variable-speed (inverter) compressors modulate output instead of cycling fully on and off, which tends to use less energy for the same cooling job than an older fixed-speed compressor.
- Placement and ventilation. A fridge pushed tight against a wall or cabinet, or standing next to an oven or in direct sun, works harder to shed the heat its compressor produces, which can push real-world cost above the published figure.
Common questions
Is the Bosch B36FD51SN* cheap to run?
Not especially. At $130 a year it ranks #952 of 1,000 refrigerator models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Bosch B36FD51SN* cost per month?
Roughly $10.86/mo, spreading the $130/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 702 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $130 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Bosch B36FD51SN* for its size?
63rd 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.
