Right next to it on the list
A rank or two either side of the ROVSUN TIWC-12CRD1: ROVSUN RVTIW-12CRD1 ($113/yr, 600 kWh/yr), then TCL H12W4KW ($113/yr, 600 kWh/yr).
Comparing ROVSUN's own models
Of the 6 ENERGY STAR certified room air conditioners ROVSUN makes, the TIWC-12CRD1 costs the most to run, $38/year more than ROVSUN's cheapest, the RVTIW-08CRD1.
Cost over its typical lifespan
NAHB's Study of Life Expectancy of Home Components puts a typical room air conditioner's service life at 10 years; run the ROVSUN TIWC-12CRD1 that long and it costs about $1,128 in electricity, on top of whatever it cost to buy.
Weighing a replacement
Efficient as certified room air conditioners go, $113/year is a reasonable baseline if you're comparing what else is on the market.
Worth comparing a few current certified models before deciding.
If you're keeping it
A room air conditioner like the ROVSUN TIWC-12CRD1 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 600 kWh/yr is ENERGY STAR's own certified figure for this model. The full Room Air Conditioner category page shows all 447 room air conditioners ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
