According to the PS website, your calculation method is wrong.

The Fifty50 tournament lobby displays the approximate amount per 100 chips to be paid out when the tournament ends. The value displayed in the Fifty50 tournament lobby is rounded down to the nearest cent, but payouts are calculated so that the entire prize pool is paid out. Note that the final payouts may experience small rounding differences in order to ensure that the total payouts equal the prize pool.
