A prorated bonus is the annual cap charge created when a signing bonus (or option bonus) is divided evenly across the years of a contract, up to a maximum of five years.
Prorated bonus is the cap accounting mechanism that makes NFL contract engineering possible. When a player receives a signing bonus, the NFL does not charge the full amount against the cap in the year it is paid. Instead, the bonus is divided equally across each year of the contract, up to a maximum of five years. This annual slice is called the prorated bonus, and it appears as a line item in the player's cap hit each year. Understanding proration is essential to understanding why cap hits often look so different from actual cash payouts. The five-year proration limit is a key constraint. If a player signs a 7-year deal with a $35 million signing bonus, the bonus is prorated over only five years ($7 million per year), not seven. This rule prevents teams from signing extremely long contracts solely to minimize annual bonus proration. It also means that extending a player's contract can "create" cap space by spreading existing bonus obligations over additional years, a technique used frequently during restructures. When a player is cut or traded, any remaining prorated bonus that has not yet been charged against the cap accelerates into the current year as dead money. This acceleration is the primary source of dead money in the NFL. For example, if a player with $20 million in remaining prorated bonus is cut after year 2 of a 5-year deal, the full $20 million hits the cap immediately. This is why teams often keep underperforming players: the dead money from accelerated proration would be worse than simply paying the player's salary. The June 1 designation allows teams to split this acceleration across two years, but the total charge remains the same.
When the Chiefs restructure Patrick Mahomes's contract, they convert base salary to signing bonus. A $20 million conversion on a contract with 4 years remaining creates a prorated charge of $5 million per year instead of a $20 million cap hit in one year.
Prorated Bonus per Year = Total Signing Bonus / min(Contract Years Remaining, 5)
