Homeowners in San Diego County, California pay a median of $5,542 a year in real estate taxes, on a median home value of $791,600.

What the San Diego County numbers mean
The median is the midpoint of the county's actual bills: half of San Diego County homeowners pay more than $5,542 a year and half pay less. The exact bill for any one home depends on its assessed value, exemptions, and which school, municipal and special districts cover it.
Set against the median home value of $791,600, the median bill works out to a derived effective rate of 0.70%. That rate is an estimate computed from the two medians — no county publishes a rate calculated this way — but it adjusts for home prices, which makes comparisons between counties more meaningful.

How the tax is worked out
Think of the final bill as three ingredients: the assessed value of the property, the exemptions subtracted from it, and the combined rate of every district the property sits in. San Diego County's medians imply a derived rate of 0.70%; applied illustratively, a $400,000 home would owe about $2,800 a year, or around $233 a month spread evenly. Individual properties depart from the illustration in both directions.
