How to use this tool

  1. Enter minutes, reviews, review seconds, new seconds.
  2. Use consistent units shown beside each input. Run the calculation and review the assumptions below.

Try this example

{
  "minutes": 30,
  "reviews": 120,
  "review_seconds": 8,
  "new_seconds": 40
}

Accuracy and scope

All due reviews take priority and use a constant average response time. Remaining time admits whole new cards; future review load, forgetting and scheduling algorithms are not modeled.
