What does the Bosch B30IB905SP cost to run per year?

At about $87 a year, the Bosch B30IB905SP costs more to run than most refrigerator models we track, rank #729 of 1,000. It uses 26% less energy than the U.S. federal standard model in its class, which would cost about $112/yr to run, a saving of roughly $25 a year. Efficiency-wise, once size is accounted for, it sits right around the class median, ahead of 52% of the models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 16 cu ft (the class spans 1.2 to 31.7), size is the clearest lever we can point to for this model's running cost.

Immediately around it on the leaderboard, the Premium Levella PRNIM20***** at $87/yr runs a little cheaper and the Marvel MPRI*24-SS*1A at $87/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 B30IB905SP's $87/yr adds up to roughly $1044 in electricity alone, before purchase price or repairs.

What it costs you over time

Running cost is an every-year number, so it compounds. At $87/yr, here is what the Bosch B30IB905SP adds up to before purchase price, water, or repairs enter the math.

1 year$87
5 years$435
10 years$870

Left running for a decade at today's US average rate, the Bosch B30IB905SP costs about $870. That is roughly $250 less than a standard model in its class, which would run closer to $1120 over the same ten years.

How the Bosch B30IB905SP compares

The refrigerator class we track runs from $8 to $149 a year. At $87/yr, it runs about $23 a year above the class median of $64, and it is about $79 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $112/yr, the Bosch B30IB905SP uses 26% less energy.

What drives its running cost

At 16 cu ft, the Bosch B30IB905SP is a mid-size refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class.

  • Interior volume. More cubic feet of cold air to maintain generally means a bigger compressor and a higher running-cost figure, even among efficient models.
  • Counter depth vs standard depth. Standard-depth models generally offer more interior volume per unit of width than counter-depth models, a tradeoff between built-in looks and cubic feet.
  • Compressor technology. How a compressor cycles, full on/off versus a variable-speed inverter design, is one of the biggest hidden differences behind two fridges with similar cubic feet but different running costs.
  • Placement and ventilation. Ventilation clearance around the back and top matters more than most owners expect; a fridge starved of airflow runs its compressor longer to hold the same temperature.

Common questions

Is the Bosch B30IB905SP cheap to run?

Its $87/yr running cost, rank #729 of 1,000, is above what most refrigerator models we track cost to run, so this is not one of the cheaper picks on electricity alone.

How much does the Bosch B30IB905SP cost per month?

About $7.27 a month, which is the $87 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: 470 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $87 a year. It covers electricity only, not the purchase price, water, or installation.

How efficient is the Bosch B30IB905SP for its size?

52nd 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.
