Salaries in Naperville, IL

You'd assume a place with a median household income over $152,000 is booming, right? But Naperville’s job market is actually cooling slightly, with unemployment ticking up to 4.5% in 2026. It’s a subtle shift, but it means competition for those high-paying roles is getting a little fiercer.

Let’s talk real purchasing power. With a cost of living index of 102.6, you’re paying a slight premium compared to the national average. A $1,507 monthly rent for a one-bedroom isn’t cheap, but it’s not the sticker shock you’d find in Chicago proper. The key is that the median income here comfortably outpaces that cost, giving residents solid financial breathing room. It’s not a bargain, but it’s a calculated value for families.

So who’s actually winning here? This is a city built on professionals. With 71.6% of residents holding a bachelor’s degree or higher, the economy runs on educated talent. Top earners are in marketing management (nearly $159,000), pharmacy, and software development. Major local employers like Edward-Elmhurst Health and a dense cluster of corporate offices along the I-88 corridor fuel these salaries. Construction and project management also thrive, tied to the city’s constant, affluent suburban development.

The catch? Salaries are high, but they’re not growing fast enough to outpace the creeping cost of living. The COL-adjusted average salary here is just $68,529. It works beautifully if you’re in a top-tier field or have a dual-income household. If you’re in a role earning closer to the city’s average, you’ll feel the squeeze more than you might expect.

The data below breaks down what you can actually expect to earn, both before and after the Naperville premium is factored in.
