Undertale’s exact current sales total across all platforms is not established by the sources available. The best current figures are third-party estimates for Steam ownership, not verified sales counts; the clearest reported sales milestone is an early half-million copies.
Is there an official total for Undertale sales?
No authoritative current total across all platforms is established in the sources cited here. The available numbers measure different things: a dated report of early sales and estimates of Steam ownership or Steam copies. None should be presented as the game’s confirmed lifetime sales.

What sales figures are available?
| Figure | What it measures | How to interpret it |
|---|---|---|
| 500,000 copies within three months of launch; the tally had doubled two months into the new year | A historical sales milestone reported by PC Gamer in a profile hosted in Steam News. | An early milestone, not a lifetime total. |
| 5,000,000–10,000,000 | Steam Spy’s estimated Steam-owner band, accessed October 8, 2026. | Owners are not the same as paid copies sold: Steam Spy says its estimate can include copies sold, downloaded free, or given out. It covers Steam, not all platforms. |
| 10,831,275–24,757,200 | Steam Page Analyzer’s modelled estimate of Steam copies, based on Steam data read October 1, 2026. | The site estimates copies by applying a copies-per-review range. It says Valve does not release per-game sales numbers and that its estimate is not a fact. |
Why do Steam estimates disagree?
They use different methods and do not necessarily measure the same thing. Steam Spy reports an estimated owner band, while Steam Page Analyzer models copies from reviews and a multiplier. Neither is a Valve-reported sales count. The estimates should not be averaged or treated as a verified total, and neither covers all platforms.

The exact current number of Undertale copies sold across platforms is not publicly established by these sources. The game had an early reported sales milestone of 500,000 copies, while present-day Steam figures are estimates with different definitions and methods. They do not establish a current lifetime total.
