MLS Salary Cap 101

Major League Soccer (“MLS”) has two distinct, and intertwined, defining features that set it apart from the rest of global soccer: Its single-entity structure, and its salary cap.

While standard in most major American sports leagues, salary caps are near-nonexistent in soccer elsewhere in the world.  Earlier this year (2021), an arbitration panel threw out the English Football League’s attempt to establish a salary cap for League 1 and League 2 (the third and fourth tier of professional soccer in England), after the English player’s union (the PFA) challenged the regime.[1]

One of the central philosophies behind MLS’s American-style salary cap is to maintain competitive balance amongst its clubs.[2]  This balance, to MLS, is fundamental to its growth strategy for North American soccer, and the league writ large. 

To MLS, parity reduces the predictability of competitive results, which creates a more interesting product for prospective fans and neutrals, which in return will lead to growth in popularity of the sport and the league —or so the theory goes.

For MLS clubs, however, competitive dominance -not balance- is top of mind.  The fundamental basis of the parity theory is that it creates a potential for all teams to win.  Essentially the draw for fans is the hope that there is a possibility in every matchthat their team will win.  So, a club on an individual basis will grow interest, fan support, market share, and revenue faster if they increase their likelihood of winningby become consistent winners.

This makes sense.  The biggest clubs and teams in the world are the ones that have the biggest histories of winning.  Real Madrid, Liverpool, the Yankees, the Lakers, all built their global fanbases with the contents of their trophy cabinets, not the fact that their matches and games had extremely unpredictable outcomes.

Therefore, soccer clubs, including those in MLS, should fight to maintain competitive dominance, not balance to grow their fanbase and improve their bottom line.

This is the first piece in a series discussing strategies MLS clubs can leverage to break the league’s competitive balance and create a model for sustained sporting (and therefore, hopefully, commercial) success in MLS. You can read the subsequent pieces here: II.

As the 2021 MLS season kicks off this weekend, it makes the most sense to start by breaking down MLS’s Salary cap in straight forward terms, to better understand the constraints by which MLS Clubs must follow as they build their rosters.[3] 

MLS Roster Limits

To effectively manage the salary cap, MLS has established limits to its clubs’ rosters.  MLS clubs’ rosters may contain between 18 and 30+1 players (an “MLS Roster”).[4] MLS further breaks down MLS Rosters into 3(ish) buckets: The Senior Roster, the Supplemental Roster, and the Reserve Roster.[5] 

MLS Salary Budget

MLS’s Salary Cap, as it is most commonly understood, covers MLS clubs’ budget on the first 18-20 players on their MLS Roster (the “Senior Roster”).[6]  In 2021, the budget for an MLS club’s Senior Roster is US $4.9M (the “Salary Budget”).[7] 

Charging the Salary Budget

This Salary Budget is a bit of a misnomer.  It accounts for all costs associated with retaining players on the Senior Roster to compete in that particular MLS season (a player’s “Unadjusted Budget Charge”), not just the player’s salary.[8]

Per the 2015[9] Collective bargaining Agreement between MLS and the MLS Players’ Association (the “MLS CBA”), a player’s Unadjusted Budget Charge includes:

  1. Any acquisition costs (e.g., transfer and loan fees) paid in that year;
  2. The player’s annual salary;
  3. Any performance bonuses paid to the player;
  4. Any loyalty bonuses, marketing fees, housing stipends and/or other guaranteed compensation paid the player in that year;
  5. Any Agent fees paid to the agent on behalf of the player by MLS in that year.[10]

Amortization of Acquisition Fees on Budget Charges

With one exception, MLS does not generally allow clubs to amortize players’ acquisition fees on the Salary Budget.[11] That exception is the Special Discovery.[12]  Each MLS club may use one Special Discovery tag to amortize acquisition fees of a player on their roster that is 27 years old or younger.[13] Without a Special Discovery tag, all acquisition fees paid in a particular year count towards a player’s Unadjusted Budget Charge.

Allocation Money

The $4.9M Salary Budget is by no means a “hard” cap.  In addition to that sum, Clubs may use certain league-established assets to stay under the Salary Budget by buying down players’ Unadjusted Budget Charges (“Allocation Money”).[14]  When a club applies Allocation Money[15] to a player’s Unadjusted Budget Charge, it reduces that player’s charge by the amount of Allocation Money applied (a player’s “Budget Charge”).[16]  So, if a player has a $500K Unadjusted Budget Charge, and his club applies $200K in Allocation Money to that player, his actual Budget Charge counted towards the $4.9M Salary Budget is $300K.

In that respect, Allocation Money, is essentially just an extension of the Salary Budget. 

In 2021, MLS Clubs have at least $1.525M in General Allocation Money (“GAM”) to use to stay below the $4.9M cap.[17] MLS clubs can, with some restrictions, use GAM on any player on their MLS Roster.[18] 

In addition to buying down a player’s Unadjusted Budget Charge, clubs may use GAM as consideration in trades for players within MLS, much like cash transfer fees work in other parts of the footballing world.[19]

As well, in 2021 MLS clubs can opt into using (at their own discretion) up to $2.8M of Targeted Allocation Money (“TAM”).  Clubs can use TAM on certain “targeted” players with Unadjusted Budget Charges between the CBA-designated Maximum Salary Budget Charge (in 2021: $612,500), and a million dollars over the Maximum Salary Budge Charge (or, $1,612,500 in 2021).[20]  The Lowest Salary Budget Charge that clubs can use TAM to buy a player down to is $150K. 

Unlike GAM, at this juncture, TAM is not tradable.[21] 

The Supplemental and Reserve Rosters

Outside of the Senior Roster, the spend on the next 10+1 players on the MLS Rosters are:

  1. Supplemental Roster: Up to four players that must have an annualized salary of, at most, Senior Minimum Salary ($81,375 in 2021);
  2. Reserve Roster: Up to six players that must have an annualized salary of, at most, Reserve Minimum Salary ($63,547 in 2021)
    1. Loaned player: One additional player that may receive Senior Minimum Salary so long as the club sends the player on loan outside of MLS for the entirety of the MLS season.[22] 

The Total Budget

In essence, the true budget for regulated player spend in MLS for 2021 is about $10,013,157 (the “Total Budget”) broken down as follows:

  1. $4,900,000 baseline Salary Budget;
  2. $1,525,000 in baseline GAM;
  3. $2,800,000 in TAM;
  4. $325,500 for the Supplemental Roster;
  5. $381,282 for the Reserve Roster and
  6. $81,375 for the loaned player.

Unregulated Spend

While MLS allows for significant regulated spend over its $4.9M Salary Budget, MLS has also established certain areas of unregulated spend that do not count towards the Total Budget. 

These areas includes:

  1. Spend on Designated Players above the Designated Player Budget Charge[23];
  2. Spend on the (still unnamed) U22 initiative players above the U22 Budget Charge[24];
  3. Spend on “Homegrown” academy developed players above Senior or Reserve Minimum Salary;[25]
  4. Spend on “Generation Adidas” players drafted in the MLS Super Draft above Senior Minimum Salary.[26]

Designated Players:

The Designated Player (or “DP”) tag is likely the most well-known MLS salary cap financial mechanism.  Each MLS club may use up to 3 Designated Player tags.  Players may qualify for a Designated Player tag so long as their Unadjusted Budget Charge is over the CBA mandated Maximum Salary Budget Charge (in 2021, $612,500).[27] 

This creates significant overlap with TAM-eligible players, as every TAM player technically qualifies as a DP.  The biggest difference between DPs and TAM, then is in that there is no financial ceiling for DPs.  Put simply, players with potential 2021 Unadjusted Budget Charges of $650K and $100M both qualify as DPs. 

For clubs with smaller budgets, where their higher-end player spend is still within the TAM threshold, the DP mechanism is more to a finical mechanism to stay under the Salary Budget.  For all clubs though, the DP tag provides the opportunity to sign a big player that can bring their team up to a new level without affecting the rest of their player spend. 

So how does this Designated Player tag work?  Essentially, any portion of a Designated Player’s Unadjusted Budget Charge above a certain threshold (that threshold being the “Designated Player Budget Charge”) is not counted towards the $4.9M Salary Budget.[28] 

The Designated Player Budget Charges are determined by a player’s age:

  1. 24 Years or older: Maximum Salary Budget Charge (In 2021: $612,500).
  2. 21-23 years old: $200K
  3. 20 years or younger: $150K (together, with Designated Players aged 21-23 years old, “Young Designated Players” or “YDPs”).[29] 

Clubs may use GAM to buy down players’ Designated Player Budget Charge to a minimum of $150K. 

In addition to those Designated Player Budget Charges, if a club intends to retain a third DP on their roster, it must pay a $150K GAM luxury tax to the league.[30]  This means that there is an additional $50K per-DP Salary Budget impact, or a net Total Budget effect of $662,500 per DP, to carry three “senior” Designated Players.  However, should at least one of those three players be a YDP, MLS waives that tax.[31] 

U22 Initiative: Further Off-Cap Spend

In addition to the DP rule, in 2021, MLS also established a U22 initiative starting to further incentivize MLS clubs acquiring young, high-value players.[32]  Under the initiative, MLS teams may spend an unlimited amount on transfer fees that are 22 years or younger so long as those players’ annual salaries are at or below the MLS’s Maximum Salary Budget Charge (so, in 2021 $612,500).[33]  The U22 Initiative works similar to DPs where All spend over a certain threshold (the U22 Budget Charge) is not counted against the $4.2M Salary Budget.[34]   

In 2021 the U22 Budget Charges are:

  1. $200K for players of 21 years old and older; and
  2. $150K for players 20 years old or younger.[35] 

The number of players that an MLS club may use this initiative on depends on the age and Unadjusted Budget Charge of their Designated Players.[36] 

If a club has three Designated Players that are 24 years or older, all with Unadjusted Budget Charges over the maximum TAM threshold ($1,612,500 in 2021) the club may only use the U22 initiative on one eligible player. [37]

However, If the club carries less than three DPs, if at least one of the club’s three DPs has an Unadjusted Budget Charge less than the Maximum TAM threshold ($1,612,500 in 2021), or at least one of the club’s three DPs is a YDP, the club can use the U22s initiative on up to three eligible players on their roster.[38] 

Homegrown Player Initiatives

MLS also provides a Homegrown (academy-developed) subsidy, allowing Homegrown players making up to $125K above Reserve Minimum and Senior Minimum salary to sit on the Supplemental and Reserve Rosters.[39]  MLS clubs may also apply TAM to Homegrown players

 Unadjusted Budget Charges on the Supplemental and Reserve Rosters to make them compliant.[40]  Academy players may also qualify for the U22 initiative.[41] 

Breaking Competitive Balance

These roster rules lay out the framework for every MLS to construct their MLS Roster.  Leveraging these rules is central to breaking MLS’s competitive balance.  These rules provide opportunities to maximize their roster’s quality if clubs approach their strategy from the framework of the rules themselves.

Outside of direct player spend, clubs can leverage significant investment in infrastructure, personnel, and player development programs, that will have direct impacts on the quality of players on their team sheet, that are completely unregulated by the salary cap.  Leveraging this off-cap spend is crucial to gain a consistent competitive edge in a league where spend for the majority of players is flat.

[3]For seasoned MLS Cap wonks, most of this will not be new, novel, or interesting.  But It seems right to set a framework for the salary cap before we start discussing strategies to maximize player value within that framework.  This also only considers the Cap effect of deals in the abstract of one season. Things (like player eligibility for certain singing initiatives) get complicated as you work on contracts that last over multiple years.  That more advanced discussion is better reserved for an MLS 102 (or 202, depending on your school of choice).
