Cost of Living Breakdown for San Antonio

All cost and FIRE figures assume a single adult.

Lean FIRE Lifestyle

$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. Texas's zero income tax keeps every withdrawal dollar intact.

Retirement Confidence

The 4% rule is a great starting point. Here we go a step further and test your plan against real market history.

Enter your portfolio on the homepage to backtest a retirement in San Antonio against market history.

How this is calculated

This is a real historical backtest. We run your plan through every retirement-length window in US market history (1871โ€“2022): a 75% stock / 25% bond portfolio, rebalanced annually, with withdrawals raised each year for that period's actual inflation. The success rate is the share of those historical start years in which the money lasted the full length without running out.

Your confidence level sets the bar: at Balanced (90%), a survival rate of 90% or more reads "You can retire here", within 10 points below is "Close โ€” worth a closer look", and lower is "Not quite yet". The same level sizes the "Needed to retire here" target. Retirement length also drives it โ€” early retirees planning 40โ€“50+ years see lower survival than the 30-year baseline.
