For the 2021–22 season, group stage participation in the Europa League is awarded a base fee of €3,630,000 with each group win worth €630,000.
That base fee was worth £3,066,636 to West Ham when converted to pounds with a group win translating to around £532,000.
With another £532,000 win bonus last Thursday over Rapid Vienna the Hammers bonus pot has already reached almost £2.4m in win bonuses plus the £3m base fee bringing the running total to £5.4m.
Winning group H has earned the Hammers another €1,100,000 (£929,000) bonus bringing the group bonuses up to £3.3m with another £532,000 up for grabs in their last group game.
West Ham are on target to earn over £6.8m from the group stage but add to that ticket revenue of two London Stadium home games so far off 50,000 and 46,000 with a third likely to be very similar.
The Hammers can also expect to get a share of the TV broadcast rights market pool meaning the group stage alone could earn West Ham over £10m.
