Want a deck that schedules reviews this way and keeps the day's work visible?
Try VocaDeck freeHow the calculation works
- It simulates every card with the app's own scheduler: a new card starts at ease 2.5 and Got it gives gaps of 1, 2.5, 6.25 days and so on, capped at 730 days.
- A new card's first look counts as a review on the day it is added.
- The result is the largest number of new cards a day, up to 200, whose busiest day within the chosen number of days fits your minutes.
- Reviews are counted on UTC calendar days. Load keeps growing slowly as intervals lengthen, so a longer period can lower the answer.
Frequently asked questions
- How many new flashcards per day should I learn?
- It depends on the time you have, not on a fixed number. Each new card comes back several times, so a daily batch becomes a daily pile of reviews. At the defaults here (8 seconds a review, every review Got it, 90 days), each new card a day adds about 6 reviews to the busiest day, so 25 new cards a day fits 20 minutes.
- Why do reviews pile up even though I add the same number of cards each day?
- A new card is reviewed again after 1 day, then about 2.5, 6.25 and 15.6 days at the default ease, so cards added on different days come due together. Reviews climb for the first weeks and then level off while you keep adding. Stopping new cards lets the load fall.
- What does the Again percentage change?
- A card pressed Again comes back after 4 hours and starts its climb again, so a higher Again rate means more reviews per new card and fewer new cards that fit your time. The calculator draws Again presses with a fixed random seed, so the same inputs always give the same answer.
- Does this account for days I skip?
- No. It assumes you review every card on the day it falls due, and it does not model skipped days or a backlog. If you miss days, the pile you return to is bigger than the table shows.
- Is this how Anki or VocaDeck works?
- It runs the scheduler inside VocaDeck, an SM-2-style rule with an ease factor per card. Anki has its own scheduler options, so treat the numbers as a guide for the shape of the load, not a prediction for an Anki deck.
