Housing plus childcare takes 52% of family income, and pay bands price only half of it

The arithmetic that matters to an employer sits at the two ends of the table. Little Rock's median family earns $73,170 and pays $9,612 for childcare and $19,539 for housing, leaving $44,019 ^[6][3]. San Jose's median family earns $176,401, more than double the national median of $83,730 in 2024, and its share works out to roughly $146,589 across the same two lines, leaving about $29,812 ^[4][1][2]. An extra $103,231 of income produces $14,207 less to live on ^[4]. Lifting a San Jose household to Little Rock's leftover takes about $190,608, roughly 2.6 times the Little Rock median ^[5].

That gap is what a geographic differential is meant to close, and typically does not. Bands are indexed to housing or to a general cost-of-living series, and childcare tracks neither. Redfin chief economist Daryl Fairweather says a cheap house does not always translate to a cheap life, citing metros where housing is a steal while childcare eats the budget, with the reverse in places like San Francisco ^[11]. Miami is the clean illustration. Its median childcare bill of $13,080 is $708 below Dayton's, and Miami families still hand over 75.3% of income against Dayton's 43.8% ^[8][9][8]. Working backward from Miami's costs and its share puts median household income there near $77,826 ^[7]. Inexpensive day care rescued nothing.

The thinnest residual in the published detail does not belong to the richest metro either. Riverside families earn $97,116, spend $68,957 on the two lines, and keep $28,159, which is below San Jose's leftover and $15,860 under Little Rock's on income $23,946 higher ^[7][6].

Redfin frames the exercise as owning a home while paying for childcare ^[13], so this is the relocation case rather than the early-career one, and relocation is where the mispricing gets expensive. Two things follow for anyone setting comp. A band can clear every local housing benchmark and still hand a parent less spendable money than the cheaper metro it was benchmarked against, because what the candidate experiences is the residual and not the band. And a childcare benefit is being priced against a bill that runs upward of $45,000 a year for some parents ^[12], which means a token subsidy shifts the household arithmetic by a rounding error, while a subsidy large enough to matter competes with salary for the same budget line. A location strategy that prices one line is pricing half the household.
