Binding of Isaac: Rebirth Wiki
For save file completion images, see Savefile Images

In terms of "percentage" of the game that is completed, the save file will show confusing values. This is because more items and unlocks were added incrementally over the lifetime of the game. The system is as follows:

  • Original: Golden God / 100%
  • WotL: Platinum God / 110%
  • Rebirth: Real Platinum God / 111%
  • (except in Rebirth) Afterbirth: 1001%
  • (in Afterbirth † and Repentance) Afterbirth+: 1,000,000%
  • (in Afterbirth † and Repentance) Afterbirth+ with 1,000,000% on all 3 save files: 3,000,000%
  • (in Repentance) Repentance: Dead God
  • (in Repentance) Repentance with Dead God on all 3 save files: Infinity%
