Flashcard Reviews Per Day Calculator
After 90 days of adding 10 new flashcards a day you have about 60 reviews a day (8 minutes at 8 seconds each); at 20 a day about 120 (16 minutes); at 50 a day about 300 (40 minutes). Every new card per day adds about 6 reviews a day, assuming every review is Got it. Choose your own pace below; the numbers come from the same scheduler that runs inside VocaDeck, and no account is needed.
| New cards per day | Reviews per day | Minutes per day |
|---|---|---|
| 5 | 30 | 4 |
| 10 | 60 | 8 |
| 20 | 120 | 16 |
| 30 | 180 | 24 |
| 50 | 300 | 40 |
At 20 new cards/day, expect about 120 reviews/day after 90 days (about 13 weeks), which is around 16 minutes a day at 8 seconds a review. The busiest day is day 65 with 120 reviews.

Want a deck that schedules reviews this way and keeps your daily load in check?
Try VocaDeck freeAssumptions behind the numbers
- Every card is reviewed on the day it falls due, and every review is Good unless you set an Again percentage.
- A new card's first look counts as a review on the day you add it.
- A new card starts at an ease of 2.5; Good gives gaps of 1, 2.5, 6.25 days and so on, capped at 730 days.
- Again returns the card after 4 hours and lowers the ease of a graduated card by 0.2.
- Days are UTC calendar days. Hard and Easy are not simulated, and skipped days are not modelled.
- The last-7-days average is the best guide to the daily load at the end of the period.
Frequently asked questions
- How many flashcards should I study per day?
- The number that matters is new cards per day, because every new card creates a stream of future reviews. Try 10, 20 and 30 in the calculator and compare the reviews per day it shows after a few weeks, then pick the new-card pace whose review time you can keep up on your worst day, not your best.
- How many reviews will I have after a month?
- With a steady number of new cards a day, reviews climb quickly for the first weeks because each cohort of new cards comes back on days 1, 2, 4 and 10 or so. Set the period to 30 days and read the last-7-days average. The figure keeps growing slowly after that as older cards return at longer gaps.
- How does the calculator work out the numbers?
- It creates each day's new cards, runs every card through the same scheduling function VocaDeck uses, and counts the reviews that fall on each day. A new card starts at an ease of 2.5, a Good on a new card comes back in 1 day, and after that each Good multiplies the interval by the card's ease. Intervals are capped at 730 days.
- What does the Again percentage do?
- By default every review is Good, which gives the lightest possible workload. Setting a percentage makes that share of reviews Again: the card returns after 4 hours, loses ease on a graduated card and is reviewed again, so the load goes up. The draws use a fixed seed, so the same inputs always give the same chart.
- Is this the same as the Anki review count?
- No. VocaDeck uses an SM-2-style scheduler. Anki has its own learning steps, interval modifiers and fuzz, and its FSRS option uses a different memory model, so an Anki deck will differ. Use this page to see the shape of a spaced repetition workload and how new cards per day drives it, not to predict an Anki deck to the day.
- Does it include days I skip reviews?
- No. It assumes you review each card on the day it falls due. Skipped days pile up as backlog in a real deck, so treat the daily figure as the workload you need to keep up with, not what a skipped week will feel like when you return.
- What is the pause option for?
- It stops adding new cards for a stretch, such as an exam week or holiday, while reviews keep coming. The chart shows how the load drains after the pause and how long it takes to recover.
