What your numbers mean
In the first year, owning costs about $6,732 a month: $4,945 mortgage payment, $502 property tax, $529 insurance, $756 upkeep. Renting a comparable home costs $2,948. So the renter has $3,784 a month left over, and invests it — on top of the $208,610 down payment and closing costs they never had to spend.
Rent rises 3.5% a year, so within 20 years it never catches up with the cost of owning (taxes, insurance and upkeep grow with the home's value too).
After 20 years the home is worth $1,804,738 (growing 3.5% a year from $907,000). You still owe $421,388 on the mortgage and pay about $108,284 to sell plus $76,837 capital gains tax, leaving $1,198,230 in equity.
The renter's investments, earning 6.0% a year, grow to $2,024,608 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.
Renting leaves you $826,378 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 $504,315 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 San Diego, CA is worth $906,700, and the median rent for a 3-bedroom rental is $2,948 a month including utilities. That's a price-to-rent ratio of 25.6 — the home costs 25.6 years of rent — compared with 26.0 across California and 17.5 nationally. By that rule of thumb the local market leans toward renting.
Between the 2015–2019 and 2020–2024 Census surveys, home values here rose 45% and median rent rose 36%. 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 0.66%, well below the 0.94% national rate — about $6,020 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 $108,077, so the median home costs 8.4× a year's income (4.1× nationally), and 47% of households own their home. Renters spend a median 32% of income on rent.
