Salaries in Castle Rock, CO

Here’s the thing about Castle Rock: you probably think it’s just a Denver bedroom community, but it’s quietly become one of the most expensive places to work in Colorado. The secret’s out, and the price tag is climbing.

With a cost of living index of 105.5, you’re paying a 5.5% premium over the national average. That doesn’t sound catastrophic, but it eats into that seemingly hefty median household income of $137,383. The real story is in the rent—a one-bedroom runs you $1,635 a month. So while your paycheck looks good on paper, your purchasing power takes a hit the moment you pay your landlord. It’s not a total bargain, but for some, it’s a reasonable trade-off for the quality of life.

This town runs on a few key engines. You’ve got the obvious tech spillover from the Denver metro, which is why Software Developers are the top earners here, pulling in a raw salary of $129,359. But Castle Rock also has a solid base in healthcare and education. The low 3.4% unemployment rate tells you it’s a worker’s market, but that 46.5% of residents holding a bachelor’s degree or higher points to a competitive, white-collar workforce. Large employers are a mix of regional healthcare systems, the town’s own school district, and a growing number of professional services firms that serve the local population.

Here’s my honest take: wages are decent, but are they keeping pace with the climbing costs? I’m not entirely convinced. The COL-adjusted average salary here is just $52,398, which feels thin for a community with this income profile. That said, if you’re a dual-income household or you land one of those top-tier tech or professional jobs, you can absolutely make it work. For everyone else, it’s a squeeze.
