How to use this tool

  1. Enter table and index allocation, estimated reclaimable share, current free disk in the displayed units.
  2. Calculate the scenario, then compare it with measurements before changing a system.

Try this example

{
  "size": 600,
  "bloat": 35,
  "free": 500
}

Accuracy and scope

Simplified full rewrite estimate; WAL, temporary sort files, indexes and database-specific behavior can require more disk.
