Flashcard Reviews Per Day Calculator
Choose how many new cards you add each day and see how many reviews are due on every day after, when the load peaks and how many minutes it costs. It works instantly and needs no account. Each card is scheduled by the same SM-2-style function that runs inside Fulin Flashcard, so the chart is a simulation, not a rule of thumb.
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 Fulin Flashcard 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 Fulin Flashcard 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. Fulin Flashcard 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.
