if anyone was curious of how much france needs to pay back:
They approximated that in total 112 million francs was paid in indemnity, which when adjusted for the inflation rate would be $560 million in 2022, but considering that if it had been invested in the Haitian economy instead, it could be valued at $115 billion.
(from Wikipedia)
and obviously, this is only from the debt. reparations for the enslavement of Haitians will cost much, much more
