$1.06M

A modest apartment near the Medical Center or in Southtown, cooking at home most nights with affordable Tex-Mex ingredients, and a paid-off car to get around. The River Walk and the San Antonio Missions are free, and breakfast tacos from local taquerias cost a few dollars. Healthcare takes a meaningful share of the budget, and there is not much room for surprises, but zero state income tax helps every dollar go further.

FIRE Lifestyle

$1.8M

A spacious home in Olmos Park or Monte Vista, regular dinners at restaurants like Mixtli and Cured, and premium Spurs tickets. You can afford good private health insurance, a late-model SUV, and regular weekend trips to Fredericksburg and the Hill Country wine region. At this budget, San Antonio feels affluent -- you eat well, live in a desirable neighborhood, and have meaningful flexibility for travel and hobbies.

Fat FIRE Lifestyle

$4.5M

A large estate in Alamo Heights, a cook who comes in several times a week, regular domestic help, and a premium healthcare plan with concierge access. You dine at the best restaurants in the city without checking prices, travel first class, and keep a nice car or two. In San Antonio, this budget goes very far -- you live as a successful professional who never thinks about daily costs, with plenty left over for charitable giving and regular travel.

Important notes on retirement confidence

A 90% confidence level is widely considered a strong retirement plan โ€” it means your portfolio survived in 9 out of 10 historically-modeled scenarios. A 95% or higher rate is extremely conservative. Reaching 100% is nearly impossible in any Monte Carlo model, because there will always be a few extreme worst-case market sequences that deplete any portfolio.

Early retirees may need portfolios to last 40-50+ years. The 4% rule was originally validated for 30-year retirements. Consider a more conservative withdrawal rate (3-3.5%) for very early retirement.
