Right next to it on the list
A rank or two either side of the Marathon MUF65BLS: EuroDesign EDV064S ($54/yr, 289 kWh/yr), then Criterion CUF66C1W ($55/yr, 292 kWh/yr).
Same brand, different models
Ranked 7 of Marathon's 11 certified freezers, this sits between the MCF36W-1 ($31/yr, the brand's cheapest) and the MFF212BLS ($93/yr, its priciest).
Lifespan
NAHB's Study of Life Expectancy of Home Components does not publish a figure for freezers, so no lifetime cost is shown here rather than a guessed one. The annual and monthly figures above stand on their own.
Is it worth replacing?
Efficient as certified freezers go, $54/year is a reasonable baseline if you're comparing what else is on the market.

If you're keeping it
Whether or not the Marathon MUF65BLS ever needs replacing, a repair is the more common failure for a freezer, one a protection plan budgets for ahead of time.
Where this number comes from
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. The full Freezer category page shows all 658 freezers ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
