Drawn as a step, not a curve: Transfermarkt reprices every squad in December and June (marked with a small tick on the axis) and revalues continuously between, so the line only moves when a real valuation changed, never by interpolation.

A month renders no value at all once the priced squad falls below 15 players, so a thin squad is never shown as a cheap one. The series is floored at July 2012 on purpose: earlier Transfermarkt totals reflect which players happened to be priced yet rather than the squad’s real worth, and are excluded rather than shown misleadingly low.

Upstream (dcaribou/transfermarkt-datasets) has been paused since July 2026, so the series ends where the source ends rather than where the season does.

Spent is the fees paid for players arriving, received the fees for players leaving, both in EUR millions by the July-to-June season of the move. A move with no fee on record (a free, a loan, an undisclosed sum) is counted, never priced: the small figure beside each total is the moves with a fee, plus those without (so 4+3 is four priced arrivals and three unpriced), and a quiet window is not mistaken for a cheap one. Wages are not here: they are estimates nobody licenses, and fees are documented.

Appreciation is the season’s change in squad value with the net spend taken out: buy 100m of players and finish 100m higher is zero; finish 120m higher and the club made 20m of players better, or the market repriced them. It needs a priced squad at both ends of the season (the same 15-player floor as the value chart), so it is blank rather than guessed for a season that lacks one.

The source has been paused since 6 July 2026, so the final row holds only the opening days of its window.
