San Antonio, TX to Philadelphia, PA is one of the bigger cost-of-living steps you can take while staying inside the U.S.: composite index up roughly 25%, housing sub-index up about 48%. Those numbers are not directly comparable — housing weighs more heavily in any household budget that is not heavily mortgaged-in or rent-controlled, which means the effective hit on take-home spending power is usually larger than the composite figure suggests.
If you are paid the same nominal salary after the move (a remote-work scenario, or a cross-company switch at flat pay), expect a meaningful drop in discretionary income and savings. The composite index assumes an average household basket; an average household in San Antonio versus Philadelphia actually consumes a slightly different basket because Philadelphia renters tend to have smaller spaces, fewer cars, and more dining out. The convergence cuts the gap a bit but does not close it — even adjusted, the move costs real money on the household budget.
Income tax is a separate axis from the cost-of-living index, and Texas and Pennsylvania can disagree on it sharply. 0.00% versus 3.07% on the top-marginal or flat state rate translates to $0 versus $2,303 on a $75,000 salary, a $2,303 delta that stacks with the consumer-price story.
Run your actual salary and filing status through the take-home pay calculator for a precise after-tax number. The federal layer is the same in either metro; only the state piece shifts. See the take-home pay calculator or the state-by-state take-home pay article for the precise after-tax number.
Yes — by about 25% on the composite. Philadelphia's C2ER index reads 114; San Antonio's reads 91. Housing is the largest line item in that gap; groceries, transport, healthcare, and utilities each add small same-direction contributions.
Plan on roughly $93,956 of gross salary in Philadelphia to match $75,000 of San Antonio purchasing power. The calculation uses the C2ER ACCRA composite ratio (114/91 = 1.25). That is pre-tax; the state-tax sidebar handles the after-tax piece.
Housing is the largest line item in any cost-of-living comparison and the one with the most metro-to-metro variance. San Antonio's housing sub-index sits at 86; Philadelphia's is 127. That gap reflects rent and home-price differences captured in the C2ER ACCRA quarterly survey. Groceries (San Antonio 90 vs Philadelphia 102), transportation (95 vs 105), and utilities (96 vs 113) all contribute, but housing is the dominant factor.
Not directly. Consumer-price indexes like C2ER ACCRA exclude state and federal income tax. To get the full picture for Texas versus Pennsylvania, combine the equivalent-salary number above with the state-tax delta in the sidebar; both effects compound when you cross state lines.
