Cost of Living Breakdown for San Antonio

Cost and FIRE figures are for a one-person household โ€” adjust household size in the controls above.

Lean FIRE Lifestyle

$714K

A cheapest-acceptable studio or older one-bedroom near the Medical Center or on the Southtown fringe, cooking at home most nights with affordable Tex-Mex ingredients and a paid-off car to get around. The River Walk and the missions are free, and breakfast tacos cost a few dollars. Healthcare takes a meaningful share and there isn't much room for surprises, but zero state income tax helps every dollar go further โ€” San Antonio runs one of the cheapest big-city budgets in the US. The Silver premium stays low only if annual income is kept under the 2026 ~$62,600 subsidy cutoff.

FIRE Lifestyle

$1.32M

A high-quality home in Monte Vista or a walkable place in King William, regular dinners at Mixtli and Cured, and premium Spurs tickets. Good coverage, a late-model SUV, and regular weekend trips to Fredericksburg and the Hill Country wine region are all within budget. At this tier San Antonio feels affluent โ€” you eat well, live in a desirable neighborhood, and have real flexibility for travel and hobbies.

Fat FIRE Lifestyle

$4.81M

A historic Alamo Heights estate or a Hill Country ranch compound minutes from the city, household help several days a week, and occasional private-chef evenings alongside the city's best tables, with concierge healthcare. Dining is anywhere without checking the bill, travel is first class, and a premium truck or SUV and car service handle getting around. San Antonio's low cost base makes this budget stretch far โ€” roughly $192k a year โ€” with plenty left for charitable giving. 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 - 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 - early retirees planning 40โ€“50+ years see lower survival than the 30-year baseline.
