What this adds up to over time
NAHB's Study of Life Expectancy of Home Components puts a typical clothes dryer's service life at 12 years; run the LG DLG3171 that long and it costs about $1,545 in electricity, on top of whatever it cost to buy.
Is it worth replacing?
The LG DLG3171 runs above its category average. If the clothes dryer 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 $129/year every year.

If you're keeping it
A clothes dryer like the LG DLG3171 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.
How this was checked
Nothing here is estimated from a nameplate wattage; the 685 kWh/yr is ENERGY STAR's own certified figure for this model. Ranked 458 of 639 certified dryers for running cost, the LG DLG3171 is also worth reading with a caveat specific to this category: the methodology page explains why ENERGY STAR's own combined-energy figure for dryers can overstate the electric bill impact of a gas model.
