Model
Ge GTW470BMM***
Rank #331 means 330 of the 388 washing machine models we track cost less to run each year; the 25th efficiency percentile means it uses less energy for its size than 25% of those models.
What does the Ge GTW470BMM*** cost to run per year?
Not many washing machine models we track cost more to run than the Ge GTW470BMM***: about $30 a year, rank #331 of 388. Adjusted for size, it is only more efficient than 25% of washing machine models we track, so part of its running cost comes from its capacity rather than efficiency alone. Its IMEF of 2.15 reflects integrated modified energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Maytag MHW8630H** at $30/yr runs a little cheaper and the Ge GTW485BMM*** at $30/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A washing machine typically stays in service for somewhere around 10 years; over that span, the Ge GTW470BMM***'s $30/yr adds up to roughly $300 in electricity alone, before purchase price or repairs.
Also sold as: Ge GTW485BMM***, Ge Adora GTW495*****.
By the numbers
The Ge GTW470BMM*** 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 $30/yr, here is what the Ge GTW470BMM*** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Ge GTW470BMM*** costs about $300. That is roughly $100 more than the class median, which would run closer to $200 over the same ten years.
How the Ge GTW470BMM*** compares
The washing machine class we track runs from $7 to $58 a year. At $30/yr, it runs about $10 a year above the class median of $20, and it is about $23 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 4.2 cu ft, the Ge GTW470BMM*** is a small washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is. The IMEF of 2.15 on this model, below the class median of 2.76, measures integrated modified energy factor; it is the number to compare directly against another model's IMEF if capacity is similar.
- Spin and wash efficiency (IMEF). A higher Integrated Modified Energy Factor means the machine wrings more useful washing (and a drier spin) out of every kilowatt-hour and gallon it uses.
- Drum volume. Drum volume sets the ceiling on how much a single cycle can wash, and it is usually the first driver of a washer's per-cycle energy use.
- Water heating. Cycle temperature, more than drum size, is usually what separates a cheap wash cycle from an expensive one on models with an internal water heater.
Common questions
Is the Ge GTW470BMM*** cheap to run?
Not especially. At $30 a year it ranks #331 of 388 washing machine 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 Ge GTW470BMM*** cost per month?
Roughly $2.47/mo, spreading the $30/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 160 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $30 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Ge GTW470BMM*** for its size?
25th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
