How to use this tool
Enter the requested values above. The result updates immediately so you can compare scenarios without creating an account or uploading data.
How the calculation works
Future size = current size + (average update size × number of updates)
Example
A 3.2 GB game receiving four estimated 0.4 GB updates could require about 4.8 GB.
Why this result matters
Updates can increase storage needs, although some stores replace existing files rather than adding every update permanently. The result is therefore a conservative planning estimate.
Tips for a more useful estimate
- Leave extra space for installation and temporary files.
- Use recent updates to estimate the average.
- Remember that cache and saved data can add storage.
Frequently asked questions
Will every update permanently add its full size?
