NBA Salary Cap Explained 2026: How It Works and Why It Matters
The NBA salary cap is the most important number in basketball that most fans do not understand. It determines which players teams can sign, which trades are possible, and how franchises build their rosters. Here is how it works.
What is the salary cap?
The salary cap is the maximum amount of money a team can spend on player salaries. For the 2025-26 season, the salary cap is approximately $141 million. The cap is calculated as a percentage of the NBA's total revenue — as the league makes more money, the cap goes up. It has increased every year for the last decade.
The NBA has a soft cap, which means teams can exceed it using various exceptions. This is different from the NFL, which has a hard cap that cannot be exceeded under any circumstances. The soft cap gives NBA teams more flexibility but also creates complexity.
Max contracts
The maximum salary a player can earn depends on their years of experience. A player with 0-6 years of experience can earn up to 25% of the cap. A player with 7-9 years can earn 30%. A player with 10+ years can earn 35%. These percentages translate to massive numbers: a 10-year veteran can earn approximately $49 million per year on a max contract.
The luxury tax
The luxury tax threshold is set above the salary cap (approximately $171 million for 2025-26). Teams that exceed this threshold pay a tax on every dollar over the line. The tax is progressive: the more you exceed the threshold, the higher the rate. A team that is $30 million over the tax line could pay $100 million or more in luxury tax penalties.
Bird rights
Bird rights (named after Larry Bird) allow teams to exceed the salary cap to re-sign their own players. If a player has been with a team for three or more years, the team can offer him a larger contract than any other team. This is why teams value homegrown talent — they have a financial advantage in keeping their own players.
Why it matters for trades
The salary cap is the reason some trades that seem obvious never happen. Teams cannot simply swap players without considering the salary implications. A team over the cap must match salaries in any trade, which often requires including extra players or draft picks to make the math work. Understanding the cap is essential to understanding why teams make the moves they do.
