What your numbers mean
In the first year, owning costs about $1,531 a month: $1,079 mortgage payment, $171 property tax, $116 insurance, $165 upkeep. Renting a comparable home costs $1,218. So the renter has $313 a month left over, and invests it — on top of the $45,540 down payment and closing costs they never had to spend.
Rent rises 3.5% a year while the mortgage payment stays fixed, so by year 11 renting costs more than owning. From then on, the buyer is the one with money left over to invest.
After 20 years the home is worth $393,978 (growing 3.5% a year from $198,000). You still owe $91,990 on the mortgage and pay about $23,639 to sell, leaving $278,350 in equity, plus $30,008 (after tax) from the monthly savings they invested.
The renter's investments, earning 6.0% a year, grow to $177,968 after 15% tax on the gains. That only happens if the money really is invested every month — renting and spending the difference makes buying the better choice almost everywhere.
Buying leaves you $130,390 richer after 20 years. With inflation at 2.5% a year, a dollar then buys what 61 cents buys today, so the gap is worth $79,573 in today's money.
The result holds up: none of the alternative scenarios below (faster or slower price growth, a lower rate, different investment returns) changes which option wins.

The typical owner-occupied home in St. Louis, MO is worth $197,500, and the median rent for a 3-bedroom rental is $1,218 a month including utilities. That's a price-to-rent ratio of 13.5 — the home costs 13.5 years of rent — compared with 15.7 across Missouri and 17.5 nationally. By that rule of thumb the local market leans toward buying.
Between the 2015–2019 and 2020–2024 Census surveys, home values here rose 37% and median rent rose 20% — prices have outrun rents, which makes buying relatively more expensive than it used to be. Recent growth is not a forecast: the calculator uses long-run averages by default, and you can change them.
Homeowners pay an effective property tax rate of 1.03%, close to the 0.94% national rate — about $2,044 a year on the median home. Property tax is money a renter never pays directly, so high-tax areas need more appreciation for buying to pay off.
The median household earns $56,160, so the median home costs 3.5× a year's income (4.1× nationally), and 45% of households own their home. Renters spend a median 28% of income on rent.
