Operator notes
At this pace you should expect roughly 130 reviews and 20 min per study day once the deck settles.
Daily study makes it easier to keep a slightly higher new-card cap without turning one missed day into backlog anxiety.
If you want headroom for busy weeks, treat 16 as the default and only climb toward 25 when reviews stay easy for multiple weeks.
How to interpret this tool
The wrong question is usually how many new cards you can survive on a motivated day. The better question is how many your ordinary week can carry without making the next reading session feel expensive.
This calculator starts from time budget, study frequency, and review speed so you can set a new-card cap that still leaves room for actual reading.

FAQ
Why is the recommended number lower than I expected?
Because reviews multiply faster than most people expect. If your goal includes reading books consistently, the safe number is usually lower than the exciting number.
Should I use the cautious or stretch range?
Use the cautious range if reading is the main habit you want to protect. Use the stretch range only when your current reviews have stayed easy for several weeks.
Does a faster review speed mean I should add more cards?
Only to a point. Faster reviews help, but they do not fully remove the emotional cost of a large queue. A small deck is often still the better system.
