How Much to Spend on a Coworker Gift: Budgets by Relationship
For most coworkers, spend $10 to $25. Stay near $10 when you give to a whole team, go up to about $50 only for a close work friend, and match the cap in any gift exchange. For your boss, chip in on a group gift instead, and federal employees have a $10 limit for gifts to supervisors.
