You see the job posting: $100,000 annually. It’s a psychological benchmark. It feels like security. But in Centennial, Colorado, the gap between the sticker price and your bank account is wider than you think.

Smart Budget Breakdown (50/30/20 Rule)
With a monthly net of $6,195, we apply the standard 50/30/20 budget model. This is the roadmap for financial health.
Needs: $3,097/mo
The Non-Negotiables
In Centennial, this bucket covers rent, utilities, groceries, and insurance.
Can you afford rent?
Yes, but you are priced out of the luxury market. The median rent for a one-bedroom in Centennial hovers around $1,800 - $2,000. After utilities and car insurance ($250+), you are left with roughly $800 for food and gas. It is tight, but doable if you avoid lifestyle creep.
Wants: $1,858/mo
The Lifestyle Fund
This is your disposable income. Dining out, the Colorado ski pass, beers in the Denver Tech Center, and shopping.
Purchasing Power: This is a healthy buffer. You can enjoy the Centennial lifestyle without sweating the small stuff, provided you don't finance a luxury vehicle.
Savings: $1,239/mo
The Wealth Builder
This is your future. At $1,239/month, you are maxing out a Roth IRA ($583/mo average) and still have $656 left for a brokerage account or emergency fund.
The Reality: This is a solid savings rate. It allows for wealth creation, but it won't make you a millionaire overnight. Consistency here is key.
Centennial Taxes vs The Competition
How does the Centennial tax burden stack up against other tech and business hubs?
The "No Tax" Myth (Austin, TX):
Austin, Texas, boasts no state income tax. On a $100k salary, you keep roughly $78,750. Centennial costs you an extra $4,400 in state tax compared to Texas. However, Texas often has higher property taxes (2%+) to compensate, while Colorado’s are generally lower (0.5%).
The Tax Black Hole (New York City, NY):
NYC combines high federal taxes with a brutal state and city tax.
- NYC Net Pay (Est): ~$67,000
- Centennial Net Pay: $74,336
The Winner: Centennial offers a "Goldilocks" zone. It isn't tax-free like Texas, but it is significantly cheaper than coastal metros like NYC or San Francisco. You pay for the stability of Colorado's infrastructure, but you aren't getting gouged.
