He’s a 55-Year-Old Software Developer. AI Is Changing His Industry. Can He Afford to Retire Early?

A 55-year-old software developer has spent decades building a career in an industry that suddenly feels less predictable than it did just a few years ago. Artificial intelligence is writing code, companies are flattening engineering teams, and many experienced developers are wondering whether the next round of productivity gains will come at their expense. With a strong retirement portfolio, a paid-off home, and growing uncertainty about the future of the profession, the question becomes straightforward: is this a good time to retire early, or is fear of industry change causing him to walk away from valuable earning years too soon?

What a Suburban Denver Retirement Actually Costs

The couple owns a $750,000 paid-off home, which eliminates the largest expense many retirees face. Even without a mortgage, however, housing still costs money. Property taxes, homeowners insurance, utilities, and ongoing maintenance can easily total about $21,000 per year.

Pre-Medicare healthcare is the biggest budget challenge. An unsubsidized ACA silver plan for two adults in the Denver area can cost roughly $24,000 annually in premiums, with another $6,000 in potential out-of-pocket expenses. Food, transportation, travel, hobbies, and other everyday spending add substantially more. After accounting for taxes and a reserve for major home repairs, a realistic retirement budget is approximately $120,000 per year.

That figure is consistent with Colorado’s cost of living, which runs slightly above the national average, and reflects the reality that housing and healthcare remain the two largest expenses for most retirees even after the mortgage is gone.

The Math at 55 With $2.2 Million

From 55 to 67, there is no Social Security. Every dollar comes from the portfolio. To fund $120,000 of spending from $2.2 million invested plus $120,000 in cash, Mark would draw about 5.4% in year one and let inflation grow it from there. For a 40-year horizon, that is well outside the safe zone. Retirement researchers have converged near 3% to 3.5% for early retirees, and even the more generous voices frame the upper bound as “around four” as a target and not etched in stone.

Once $62,000 in Social Security starts at full retirement age, the gap drops to roughly $58,000 in today’s dollars, which a $2.2 million portfolio can sustain. The problem is the twelve-year bridge that must come first, during which the portfolio is drained at the worst possible time for sequence-of-returns risk.

Run it yourself at 5.4% versus 3.5% and the difference is the difference between running out in your late seventies and dying with money left over.

Don’t Miss This Colorado Wrinkle

One of the biggest risks for a 55-year-old retiree is not the portfolio. It is health insurance. Before Medicare begins at age 65, ACA premium subsidies are based largely on household income. A retiree who funds spending entirely from traditional 401(k) or IRA withdrawals can inadvertently increase taxable income enough to reduce or eliminate those subsidies. The result can be thousands of dollars in additional annual healthcare costs.

The solution is to be strategic about where retirement income comes from. Drawing first from cash reserves, taxable investment accounts, or Roth assets can help manage taxable income during the years before Medicare eligibility. Keeping income lower can preserve valuable ACA subsidies and substantially reduce healthcare costs over the course of a decade.

For many early retirees, the difference between an efficient withdrawal strategy and a poor one can amount to tens of thousands of dollars. That makes healthcare planning just as important as investment planning when evaluating whether retirement at 55 is financially sustainable.

The Three Ways the Numbers Can Work

A retirement budget of roughly $120,000 per year is difficult to support indefinitely with a $2.2 million portfolio, especially when retirement begins at age 55. Even after accounting for future Social Security benefits, the margin for error is relatively thin.

There are three realistic ways to improve the outlook.

• The first is to continue working for several more years while maximizing retirement contributions. A few additional years of earnings, savings, and investment growth could substantially strengthen the portfolio before retirement begins.
• The second is to retire now but adopt a lower spending target. Reducing annual expenses would lessen the strain on the portfolio and improve long-term sustainability.
• The third option is a hybrid approach: leave the full-time job while continuing to earn income through consulting, contract work, or part-time projects. For many experienced software developers, this can provide the best of both worlds. It reduces dependence on a traditional employer while allowing investment assets additional time to grow.

The concern about AI-driven disruption is understandable. But from a purely financial perspective, walking away from a high-income career at 55 creates its own risks. The strongest versions of this retirement plan involve either a few more years of full-time employment or a transition into part-time work that preserves income while reducing exposure to the pressures of a rapidly changing industry.
