Game Save Backup Storage Calculator
Enter the number of games, average save file size, save slots per game, and how many backup generations to keep. The calculator shows the total save size and recommended storage with a 2× buffer.
Formula
Total Save Size = Games × File Size (MB) × Slots × Backup copies
Recommended Storage = Total × 2 (includes headroom for future saves)
Most game saves are between a few MB and a few hundred MB. RPGs and open-world games tend to be larger; indie games are typically smaller. Check the actual save folder for exact sizes.
Where Are Save Files? (Steam)
Most Steam saves are in %AppData%\Roaming, Documents\My Games, or the game's installation folder. Steam Cloud auto-syncs saves for supported games.
