How does transfer over 48 months work

[julystork]

Say I wanna buy a player whose club wants 4.2M plus 10% profit from next sale
Which equates 120k upfront & 85k over 48 months?

But the response: 210k offer rejected? So how does this "transfer over 48 months" work?

offer 500k and rest over 48 months maybe add 10% on top as interest payment too

Seems like the 85k you offered was over the whole period of 48 months, not 85k per month. You need to put in the whole amount you intend to pay over the specified period, so if you are offering 120k up front then you need to put 4.1m over 48 months.
