Right next to it on the list
A rank or two either side of the Whirlpool WRMF3736SW: Whirlpool WRMF3736SV ($138/yr, 733 kWh/yr), then Whirlpool WRMF3736SZ ($138/yr, 733 kWh/yr).
Within the Whirlpool lineup
Ranked 152 of Whirlpool's 156 certified refrigerators, this sits between the AMA27S1E ($40/yr, the brand's cheapest) and the WRF995FIF*** ($142/yr, its priciest).
Cost over its typical lifespan
13 years is NAHB's typical service life for this category; at $138/year, the Whirlpool WRMF3736SW adds up to about $1,791 in electricity over that span.
Is it worth replacing?
The Whirlpool WRMF3736SW runs above its category average. If the refrigerator you actually own is older still, likely well past ENERGY STAR's efficiency baseline when it was made, a current certified model could cost meaningfully less than this model's $138/year every year.
Worth comparing a few current certified models before deciding.
If you're keeping it
A refrigerator like the Whirlpool WRMF3736SW is a real household expense whether or not it needs replacing yet; a protection plan is one way to budget for a repair rather than a full replacement.
Where this number comes from
Nothing here is estimated from a nameplate wattage; the 733 kWh/yr is ENERGY STAR's own certified figure for this model. The full Refrigerator category page shows all 4,704 refrigerators ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
