Definition
Months of supply is how many months it would take to sell every home currently on the market at the pace homes have actually been closing. A low number means listings are getting absorbed fast. A high number means inventory is piling up faster than buyers are closing on it.
It compares what is for sale right now with what has been closing. That is supply against demand, not asking prices or how a market feels.
Months of supply = active listings divided by average monthly closings over the last 6 months (homes closed in the last 6 months divided by 6).
4 months of supply or less is a seller's market, above 4 and under 6 is balanced, 6 or more is a buyer's market.

Common questions
The same formula and thresholds used on every market page here.
Six months smooths out normal week-to-week and month-to-month swings in closing pace without going stale. A shorter window reacts to noise. A window over a year reacts too slowly to an actual shift in the market.
4 months of supply or less is a seller's market, above 4 and under 6 is balanced, 6 or more is a buyer's market. At the low end, listings are getting absorbed faster than new inventory can replace them, and sellers hold more leverage on price and terms. At the high end, buyers have more homes to choose from and more room to negotiate.
Not automatically. Months of supply measures pace, not price. It is a leading indicator. A market that stays above six months for a sustained stretch tends to see price growth slow or reverse, but the two numbers can diverge for months before price catches up.
