Cost over its typical lifespan

Weighing a replacement
The Marathon M4-150SS is already efficient for its category at $25/year. If you're shopping and comparing options, this is roughly what a well-chosen new refrigerator costs to run.
Compare current ENERGY STAR certified refrigerators before buying.
Protecting what you have
Whether or not the Marathon M4-150SS ever needs replacing, a repair is the more common failure for a refrigerator, one a protection plan budgets for ahead of time.
Sourcing
Nothing here is estimated from a nameplate wattage; the 134 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.
