Software engineers are the most represented profession in the FIRE community, and for good reason: median TC (total compensation) at major tech companies runs $180,000–$400,000+, including base salary, bonus, and RSU vesting. With that income, a 25–35% savings rate builds a $2M FIRE number in 12–18 years. Most SWEs who reach FIRE do so at 38–47, often driven by burnout, a desire for autonomy, or financial independence as a psychological backstop to negotiate from.

The RSU component of SWE compensation creates unique FIRE planning considerations. RSUs vest as ordinary income — taxed at your marginal rate (32–37% federal for many SWEs). Selling RSUs immediately upon vesting and investing in diversified index funds is the standard FIRE-community advice, though many SWEs make the mistake of holding employer stock hoping for continued appreciation. The risk is concentration: if your employer's stock drops 50% and you've held all your RSUs, your portfolio takes a catastrophic hit unrelated to your FIRE progress.

Mega backdoor Roth is a core SWE FIRE tool. Many major tech employers (Google, Microsoft, Meta, Amazon) offer after-tax 401k contributions and in-service Roth conversions. This allows SWEs to contribute up to $69,000/year (2025) to their 401k — $23,500 pre-tax + $7,500 catch-up (if 50+) + up to $46,000 in after-tax contributions converted to Roth. At $180K TC, an SWE maxing mega backdoor Roth shields 38% of their income from tax while building a massive tax-free retirement fund.

Geographic arbitrage is a powerful lever for SWEs due to remote work prevalence. Moving from SF or NYC ($12,000/month cost of living) to a mid-tier city ($5,000–$7,000/month) or abroad (Portugal, Mexico, SE Asia at $2,500–$4,000/month) dramatically reduces both your required FIRE number and your accumulation timeline. A SWE earning $180K in Des Moines vs. San Francisco keeps far more after-tax income (no CA state income tax) and needs a much smaller nest egg to maintain the same lifestyle.

Frequently Asked Questions

What is the average FIRE number for a software engineer?expand_more

Most SWEs targeting FIRE plan on $7,000–$12,000/month in retirement spending ($84K–$144K/year), requiring $2.1M–$3.6M. High-cost-city SWEs often need $3M+; those in low-cost areas can retire on $1.5M–$2M. Frugal SWEs living on $4,000–$5,000/month need only $1.2M–$1.5M.

How do I factor RSUs into my FIRE plan?expand_more

Count RSUs as income when they vest, not when granted. Add vested RSU value to your annual income for that year. For FIRE planning, model your average annual TC including expected RSU vesting, not just base salary. Sell RSUs immediately upon vesting and reinvest in diversified index funds unless you have strong conviction about your employer's specific stock.

What is the best 401k strategy for a software engineer?expand_more

If your employer offers mega backdoor Roth: max it. Contribute pre-tax to reduce current taxes ($23,500 traditional + catch-up if 50+), then max after-tax contributions for Roth conversion. If mega backdoor isn't available: traditional 401k to reduce taxes now (32–37% bracket), plus backdoor Roth IRA. Add HSA if on a high-deductible health plan.

When can a software engineer retire early?expand_more

With $150K+ TC and a 30–40% savings rate, most SWEs can retire at 40–50. At $200K+ TC saving 35%: roughly 15 years from $0 to $2.5M (retiring at 45 from age 30). At $300K+ TC saving 40%: possible in 10–12 years. The main risk is lifestyle inflation — upgrading home, car, dining as income grows is the primary FIRE killer at SWE income levels.

Should a software engineer use Roth or traditional 401k?expand_more

At $180K+ base salary, traditional 401k has a clear advantage — you're saving at 32–37% marginal rates now, likely withdrawing at 22–24% in retirement. The tax arbitrage is real. However, Roth accounts provide tax diversification and no RMDs in retirement. The optimal strategy for most SWEs: traditional 401k max + mega backdoor Roth (if available) + backdoor Roth IRA.
