The NFL salary cap is the league’s way of forcing every team to live in the same neighborhood financially. It is not a perfect equalizer, but it stops the richest owners from hoarding talent forever. And it is why your favorite team can go from “all in” in March to cutting a starter in August that everyone swore was safe.
Let’s translate the cap into normal-people language: what counts, why bonuses get “spread out,” what “dead money” actually means, and why contract restructures show up in your timeline like clockwork.
What the salary cap is
The salary cap is a league-wide limit on how much each team can spend on player compensation in a given season. The exact dollar number changes every year and is driven by the CBA’s revenue formula, with the cap ultimately tied to league “All Revenue” and the players’ negotiated share (plus adjustments).
Key idea: the cap is about accounting timing, not just cash. A team can pay a player a big chunk of money today, but the cap may account for that hit over multiple years depending on how the contract is structured.
Cap space vs. cash
- Cash is what the owner actually pays out.
- Cap hit is how much of that player’s pay counts against the cap this season.
Those are often very different numbers, and that is where all the “wizardry” comes from.
What counts toward the cap (and what does not)
Most player compensation counts. The common buckets you see in contract reports:
- Base salary: The weekly paycheck. This usually counts fully in that season.
- Signing bonus: Money paid up front for signing, but it usually hits the cap over time (more on that below).
- Roster bonus: Paid if the player is on the roster on a certain date. Often counts in that year.
- Workout bonus: Paid for participating in offseason programs. Counts in that year.
- Incentives: Performance-based bonuses that can count differently depending on how likely they are.
What typically does not count against the cap: non-player spending like coaches, facilities, and front office salaries. The cap is primarily about players.
Signing bonus proration
A signing bonus is the classic cap tool because the NFL lets teams prorate that bonus across the length of the contract, up to five years for cap purposes. That five-year cap window can include added years in the deal, including common “void years” that exist mostly to spread out proration.
Plain language: the player gets the money now, but the cap charge gets spread out.
A quick example
Say a player signs a 5-year deal with a $25 million signing bonus. For cap purposes, that bonus can be split:
- $25 million ÷ 5 years = $5 million cap charge per year (from the signing bonus alone)
Then you add the player’s base salary for that season to get the full cap hit.
Why teams do it
Proration helps teams keep the current-year cap hit lower so they can build a stronger roster right now. The tradeoff is that you are committing future cap space to today’s spending. That is the “credit card” analogy fans use, and it is not wrong.
Guaranteed money
When you hear “$80 million guaranteed,” that is the money the player is likely to collect even if performance dips or injury hits. Guarantees can come in different forms:
- Signing bonus: Virtually always guaranteed once signed.
- Guaranteed base salary: Salary that is protected for injury, skill, and/or cap reasons depending on the language.
- Roster bonuses guaranteed: Paid regardless of whether the player hits the roster date.
Guaranteed money matters because it often becomes the main ingredient in dead money if the player is cut or traded.
Dead money
Dead money is cap space charged to your team for a player who is no longer on the roster. It is typically leftover prorated signing bonus (and sometimes other guaranteed amounts) that has not yet hit the cap.
The proration accelerates rule
Using the earlier signing bonus example: a player has a $25 million signing bonus prorated at $5 million per year. After two seasons, you trade or cut him.
- He has already accounted for $10 million (2 years × $5 million).
- The remaining $15 million of prorated bonus has not hit yet.
When he leaves, that remaining $15 million typically accelerates onto your cap as dead money.
The one big timing trick you will hear about is post–June 1 treatment. If a player is released after June 1 (or released earlier with a post–June 1 designation), the remaining proration can usually be split: this year gets the current year’s proration, and the rest hits next year. Same pain, different calendar.
That is why teams sometimes keep a player they do not love: cutting him might create a bigger cap problem than keeping him for one more year.
Cutting a player
When a team cuts a player, fans often assume the team “gets all that money back.” Not exactly.
Here is the simple rule of thumb:
- Cutting a player saves cap space only if the cap hit you remove is larger than the dead money you create.
A quick cut example
A player’s cap hit this year is $12 million. If cutting him triggers $9 million in dead money, the team saves:
- $12 million minus $9 million = $3 million cap space saved
That is a real savings, but it is not the full $12 million headline number.
Trades
From a cap perspective, trades and cuts often look alike: the old team usually keeps the leftover prorated signing bonus as dead money, while the new team takes on the player’s remaining base salaries (and any new bonuses they negotiate).
Small caveat, because the cap loves fine print: certain bonus types and timing (option bonuses, roster bonuses due soon, guarantees that have already been paid versus still owed) can change the exact split. The basic idea still holds, but the details can get spicy.
A quick trade example
If a player is traded:
- Old team: eats remaining prorated signing bonus as dead money (in most cases).
- New team: pays the remaining non-bonus salary obligations and any new money in a restructure or extension.
This is why you sometimes see trades where the original team “pays” a lot to move the player. They are not writing a new check so much as they are accepting the cap consequences of past bonuses.
Restructures
A restructure is usually a team converting some of a player’s base salary into a signing bonus. That lowers the player’s cap hit now because the bonus gets prorated into future years.
It is the cap equivalent of moving money from the “pay today” column to the “pay later” column.
A quick restructure example
Player has:
- $18 million base salary this year
- 3 years left on the deal
Team converts $12 million of that salary into a signing bonus:
- Cap relief this year: base salary drops by $12 million
- New prorated bonus: $12 million ÷ 3 years = $4 million added to each year’s cap
Net effect: the team creates immediate cap space, but future cap hits rise.
Why teams restructure mid-season
- Injury replacements: You need space to sign a veteran when the depth chart gets ugly fast.
- Trade deadline flexibility: Space to absorb a new player’s salary.
- Practice squad elevations and bonuses: Small moves add up.
- Rolling cap plans: Teams forecast multiple seasons, not just Week 1.
Extensions
When a player gets an extension, fans think it is purely a reward. It is also a cap strategy.
Adding years gives teams more runway to prorate bonuses and smooth out cap hits. It can lower the current year cap number and create flexibility, especially when a star is entering the final year of a deal with a huge base salary.
How it usually looks
You will often see this pattern:
- Star has a massive cap hit in the final year.
- Team extends him with a new signing bonus.
- Cap hit drops this season, but the team commits to multiple years going forward.
It is less “discount” and more “we will pay you, just not all on this year’s cap ledger.”
Void years
Void years are the cap trick that sounds fake because, well, it kind of is. Teams add extra years that automatically void later, mainly to stretch bonus proration over more seasons and lower today’s cap hit.
The player usually is not expected to actually play on those void years. But the cap still counts the proration while they exist. When the deal voids, any remaining prorated bonus generally accelerates into dead money, which is why void years are helpful now and annoying later. Again, credit card logic.
Franchise tag
The franchise tag is a one-year mechanism that allows a team to keep a top free agent from hitting the market. The tagged player’s salary is high and, for cap purposes, becomes a clean one-year charge once the tag is applied and the player signs the tender.
There are variations (exclusive vs. non-exclusive), but for most fans the key points are:
- It is expensive up front.
- It buys time. Teams can negotiate a long-term deal while keeping the player under control.
- It can lead to trades. If a long-term deal stalls, a tag can function like a “we will move you for value” placeholder.
Why the tag shows up in cap conversations
Because it is usually a big, clean cap number. No proration magic, no multi-year smoothing. Just a heavy one-year charge that can crowd out other spending unless the team makes other moves.
Incentives
Contracts often include incentives like making the Pro Bowl, hitting sack totals, or playing time thresholds. The important cap wrinkle is how likely the incentive is considered.
The official labels are:
- LTBE (Likely To Be Earned): counts on the current year’s cap because it was achieved in the prior season (or meets the CBA test).
- NLTBE (Not Likely To Be Earned): usually does not count right away, but if the player hits it, it generally charges next year’s cap.
And the flip side: if an LTBE incentive is not earned, the team typically gets a cap credit next year. That is why an “up to $10 million” contract headline can be misleading. It is not fake money, but it is conditional money with delayed accounting.
Over the cap
You will hear that a team is “$20 million over the cap” in February. That does not mean the league is about to repossess their helmets. It means the team is projected over the upcoming season’s limit and needs to make moves before the relevant deadlines.
Common solutions:
- Restructure a veteran deal
- Extend a core player
- Release a player with a manageable dead-money hit
- Trade a player and accept dead money to clear future cash and cap
Also worth knowing: unused cap space can be carried over to future years if a team elects to do it. So “cap space” is not just a number, it is a planning choice.
It is a roster-building puzzle. The cap forces tough choices, but it also creates the annual offseason drama we all pretend we hate and then binge anyway.
A quick glossary
- Cap hit: What counts against the cap for that player this season.
- Cap space: How much room a team has under the cap right now.
- Proration: Spreading a signing bonus over multiple years for cap purposes (up to five years).
- Dead money: Cap charges for a player no longer on the roster, usually from remaining prorated bonus.
- Post–June 1: Release timing/designation that can split remaining proration across this year and next year.
- Restructure: Converting salary into bonus to create cap space now.
- Extension: Adding years and new money, often to lower a current cap number and keep a player long-term.
- Void years: Added years that exist mainly to stretch proration and lower current cap hits.
- Franchise tag: One-year retention tool for a top free agent at a high salary that functions as a big single-year cap number once signed.
- LTBE/NLTBE: Incentive buckets that determine whether a bonus counts this year or can hit next year.
Putting it together
Next time you see “Team X clears $14 million with a restructure” or “Team Y cuts a veteran to save $6 million,” ask two questions:
- Where did the cap hit move? Did it disappear, or did it shift into dead money or future years?
- What is the team trying to do next? Create room for a draft class, a free-agent signing, an extension, or a mid-season trade?
The cap is not just accounting. It is strategy. It is team-building philosophy. And sometimes, it is a franchise admitting, quietly, that yesterday’s bets did not pay off.
