Filip Kostić family has been a constant source of support throughout his footballing journey. While details about his parents are kept private, their encouragement was crucial during his early years in his hometown of Kragujevac, Serbia. This backing was vital in his decision to move abroad to pursue his professional ambitions at a young age, an option that wasn't encouraged in most families.
Kostić started his career at an early age, joining the academy of his local club, Radnički Kragujevac. He made his first-team debut for the club at the age of 17, quickly showing maturity and talent that attracted attention from various European clubs. This led to a move to the Dutch club Groningen, which kick-started his career in Europe. After making his mark in the Eredivisie, he moved to Germany, where he starred for Stuttgart, Hamburg, and Eintracht Frankfurt. His spell with Frankfurt was the most remarkable, with him playing an instrumental role in their 2021-22 UEFA Europa League title win, where he was named the tournament's best player. In 2022, he made a major move to Juventus, and later to Fenerbahçe on loan. However, he failed to make an impression in Turkey, with the Serbian winger currently playing for Juventus after returning from loan.
Filip Kostić net worth is estimated at around €20 million as of 2025. According to Transfermarkt, the Serbian winger currently has a valuation of €15 million. His high-profile moves to top European clubs like Juventus and Fenerbahçe have cemented his status as one of the highest-earning Serbian players. These transfers have significantly boosted his earnings throughout his career, along with various performance-based bonuses and endorsement deals. Kostić has a long-standing affiliation with sports brand Adidas, which supplies his boots and on-pitch gear. As an established international and a key player for a major club, Kostić net worth is expected to remain strong as he continues his career at the highest level.
