For my loans in Charged-Off status, I had:
- Purchase Price: $1,781.64
- Net Received: $646.023306
-----------------------------
- Total loss: $1,135.616694
- 1st Settlement Payment: $39.47
That makes for ~3.4756%
Edit: Of note, on some of my notes in Charge-Off state, I had more net received than the purchase price of the note. To fit in with your 3.4-3.5%, the extra net received on those notes are counting against me when I don't think they should. I don't want to have those notes included in my calculations, but they are.
Edit2: If I use gross received (before I paid prosper and collection fees) instead of net received, the settlement percentage comes out to almost exactly 3.5%
