Where the money goes
Every 2026 NFL rookie earns the same $885,000 base salary in year one, paid in 18 weekly game checks. After taxes that is about $27,854 a week, during the season only. The real money for a pick like this is the $5,330,404 signing bonus, which lands as one lump sum.
Bonus checks are withheld at a flat 22% federal on the first $1 million and 37% above that, plus Medicare and state tax. Many states tax a signing bonus only where the player lives, which is why where a rookie lives the day it is paid can matter.
These figures assume he lives in Missouri, files single, and pays a standard agent fee. Change any of that in the calculator to see your own version.
