Comparing LG's own models
LG makes 144 ENERGY STAR certified clothes dryers; this one ranks 112 of 144 for running cost, between the brand's cheapest, the DLHC1455* at $25/yr, and its priciest, the WSGX201H*A at $129/yr.
Cost over its typical lifespan
NAHB's Study of Life Expectancy of Home Components puts a typical clothes dryer's service life at 12 years; run the LG DLGX3901* that long and it costs about $1,545 in electricity, on top of whatever it cost to buy.
Is it worth replacing?
The LG DLGX3901* 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.

Protecting what you have
A clothes dryer like the LG DLGX3901* 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.
The data behind this page
Ranked 486 of 639 certified dryers for running cost, the LG DLGX3901* 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. The 685 kWh/yr figure is ENERGY STAR's own certification, not a wattage estimate; exact dataset IDs are on the data sources page.
