Common Scenarios
Living on $30,000 in Colorado
Colorado's flat tax rate is set in the state constitution — voters must approve any increase, which is why it keeps drifting downward. The median household income in Colorado is approximately $87,598 — meaning a $30,000 salary is $57,598 below the state median, and $50,610 below the US national median household income of $80,610.
Colorado's cost of living index is 105 (US average = 100), so your $25,673 net pay has the purchasing power of approximately $24,451 in an average-cost state. Denver, Colorado Springs, and Aurora all sit near the national cost-of-living average.
Living on $30,000 in Denver
In Denver — Colorado's economic hub for tech, aerospace, and energy — a $30,000 salary translates to roughly $2,139 in monthly take-home pay. The average 1-bedroom asking rent is around $1,750/month, which would consume about 81.8% of your net income. That's well above the 30% rent-to-income guideline — housing will be tight.
