How these numbers are made

Property tax: 2025 St. Louis County rate book, residential rates for tax code 116AZ (Kirkwood school district, which serves the great majority of the Kirkwood-Des Peres area; part of Des Peres is in the Parkway school district at about 5.30 per $100 total, similar). Rates are per $100 of assessed value, applied to the Census median home value of $609,200 x 19% assessment ratio. Des Peres levies no city property tax; it adds a Des Peres road & bridge rate and the $28 yearly sewer lateral fee.
Trash, recycling and yard waste are paid by the City through its Waste Connections contract; residents pay nothing.
Water: Missouri American Water Rate A for St. Louis County ($11.00/month, $10.3749 per 1,000 gallons) plus the $0.75071 surcharge per 1,000 gallons effective Aug. 15, 2026, plus the $1.00 monthly service line charge. Sewer: MSD base $34.85/month plus $7.15 per CCF of winter-quarter use.
Electricity: Ameren Missouri Schedule 1(M), annualised 4 summer months at 15.60 cents and 8 months at 10.62 (first 750 kWh) or 7.14 cents. Gas: Spire Missouri St. Louis County rates, annualised from the two published periods plus the rider.
Utility tax: Des Peres charges gross receipts taxes of 3.37% on electric, 4% on gas and 5% on water. The calculator takes one rate (3.37%, applied to electric and gas), so the 5% water tax is built into the stored water charges (x1.05) and the gas charges are scaled by 1.04/1.0337 to make the gas tax 4%.
No homestead exemption applies in Missouri on these rates; the Property Tax Credit for seniors/disabled is state-run and not modeled.
Nothing here is legal, tax or insurance advice.
