Steam's Sale Calendar by the Numbers: Which Months Actually Have the Most Discounts

Everyone who buys on Steam knows the big sales exist. What I wanted to know was how lopsided the calendar actually is: how much of the year's discounting happens inside those two-week windows, and whether the months in between are worth waiting through or worth buying in. The tracker's history has a start date for every discount it has ever recorded, so the question is just a matter of counting.

What follows is every recorded sale start in the ATLGames price history, 264,868 of them across 8,479 Steam games, sorted by the calendar month it began in, with all years pooled. The data runs through early October 2026 and goes back to 2020 for the longest-tracked games, so each month has several years behind it.

Sale starts by month

A flat calendar would put 8.3% of sales in each month. Instead the spread runs from 5.0% in July to 14.2% in June, a factor of nearly three between the quietest and busiest months. The four seasonal-sale months (June, December, March, November) hold 49.3% of all starts between them, which means the other eight months share the remaining half.

June is bigger than December

I had assumed the Winter Sale was the main event, partly because it lands in gift season and partly because that is the one people talk about. The numbers say otherwise: June starts about 2,600 more sales than December, and roughly 2.8 times as many as July. The Summer Sale starts in the last week of June, so some of its discounts spill into July's count and July still finishes last.

The cause is probably mundane. The Summer Sale is the event publishers plan around, and a lot of the themed sales and publisher weekends that fill the earlier weeks of June are positioned as its warm-up. December gets the Winter Sale and little else, because the Autumn Sale has just drained the pipeline a few weeks earlier.

October is the sleeper month

The surprise in the table is October at 9.5%, higher than any month without a seasonal sale and higher than February and September. The reason is a stack of smaller events: Steam Scream Fest and the wider Halloween sale window, a Next Fest, and a run of publisher sales timed before the holiday quarter. For horror and anything adjacent to it, October is effectively a fifth seasonal sale.

March is the other month that outperforms its reputation, because the Spring Sale is newer than the others and a lot of buyers still think of the calendar as three events. It is four, and March is nearly as busy as November.

The dead zone is July and August

Combined, July and August hold 10.4% of sale starts, less than June on its own. If a game you want did not go on sale in the Summer Sale, the data says the next realistic shot is late September or October, and the next high-probability shot is the Autumn Sale in late November. That is a three-to-five month wait, and it is the longest predictable wait on the calendar.

The practical consequence runs against instinct. A decent discount in mid-July on a game you actually want to play is worth more than the same discount in mid-June, because the June buyer can wait a few days for the seasonal sale and the July buyer is looking at the autumn.

How this interacts with the six-week rhythm

In the companion article I found that the median game goes on sale every 41 days. The monthly distribution explains where that number comes from: a game that takes part in all four seasonal sales plus one or two themed events lands at roughly six weeks between discounts without anyone planning it that way. It also explains the exceptions. A game whose publisher only ever joins the seasonal sales will show a cadence closer to 90 days, and its game page on ATLGames will say so.

A waiting guide by month

If it is currently one of these months and the game you want is not at a good price, this is the next window the data points to.

Two caveats. First, this counts how many sales start in a month, not how deep they are; a seasonal sale is where many games hit their floor, but the floor itself is a property of the game, and the article on the quality premium covers why. Second, "high probability" is about the market, not a specific title. The cadence figure on each game page is the better guide for a game you are actively watching.
