Fee drag differs too: Mansa X charges 5% per year plus a performance fee above a 25% hurdle, Oak a flat 6% per year, and both report returns net of those fees.

Is this calculator affiliated with SIB or Faida Investment Bank?
No. PesaCalc is independent and not affiliated with either manager. This tool compounds the net rates you choose (defaults come from each fund’s published figures) and is an illustration, not a projection, offer or investment advice. Returns are not guaranteed and you could lose part of your investment.
