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.
The base fee was worth £3,066,636 to West Ham when converted with a group win translating to around £532,000.
With another £532,000 win bonus last night over Genk the Hammers bonus pot has already reached almost £1.6m in win bonuses plus the £3m base fee bringing the running total to £4.6m.
Winning the remaining group games will earn the Hammers another £1.6m while there is also a €1,100,000 (£929,000) bonus for winning the group meaning another £2.5m is up for grabs at this stage of the European competition.
West Ham are on target to earn over £7m from the group stage, add to that ticket revenue of two London Stadium home 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.
