ZIP Code 63303

ZIP code 63303, anchored by Saint Charles, sits in solidly middle-to-upper-income territory. A median household income of $99,138 and per-capita income of $58,928 exceed statewide norms, while a median home value of $321,100 points to a housing stock priced above entry level. Property taxes run at an effective 1.08% at the county level, so a home at that median value carries a meaningful annual bill. Add a combined sales tax rate of 7.95%, and daily purchases chip in steadily. Households here generally earn enough to absorb both without strain.
