How Many Anki Cards Per Day Should You Do?

How many Anki cards per day should you aim for?

There is no single right number, but there is a well-mapped range. Cade McNiven, who has written carefully about pacing, lays it out: under ten a day is an advanced maintenance pace, ten to fifteen is slow and steady, twenty to twenty-five is a solid standard, around thirty is the sustainable cap for most people, and forty to sixty is the beginner range for clearing a large backlog. Past a hundred a day is a short burst, not a habit.

The planner above skips the guesswork. Give it the cards you have left and the days until your exam and it works out the pace that finishes in time, then shows the review load that pace generates so you can sanity-check it against your own tolerance. That second number is the one people forget, and it is the whole reason a deck-versus-deadline calculation is more honest than picking a round number like twenty and hoping.

If you have not decided on a deadline yet, the SM-2 spaced repetition calculator runs the same idea from the other end: fix a new-cards-a-day pace and it simulates the day-by-day review curve it builds.

Why your reviews explode when you rush new cards

The AnkiWeb manual is blunt about this. Studying new cards temporarily increases the number of reviews you have to do, because newly-learned material has to be repeated several times before the delay between repetitions can grow appreciably. Add twenty cards today and you are not adding twenty reviews once; you are adding a cluster of near-term reviews that overlaps with yesterday’s cluster and last week’s.

That overlap is why doubling your new cards a day roughly doubles your daily reviews a week later, not the same day. The pile keeps climbing until the oldest cards’ intervals finally stretch into weeks and months and start leaving the daily queue. Rush the new cards and you feel fine for three days, then the reviews land all at once. The budget warning in the planner exists to show you that landing before you commit to a pace you cannot sustain.

How the pacing math works

The pace itself is simple division: the cards you have left divided by the study days before your exam. Study five days a week instead of seven and the tool spreads those sessions across the calendar so the finish date stays honest.

The review multiplier, and where it comes from

The harder part is the review load, and the planner does not invent a precise-sounding number for it. It uses a stated multiplier: roughly ten reviews a day build up per new card a day at 90% retention. That figure is pinned to AnkiWeb’s own anchor, that learning twenty new cards a day consistently settles near two hundred reviews a day. A higher retention target shortens your intervals, so cards come back sooner and the multiplier climbs toward thirteen; a lower target stretches them and it drops toward eight. The whole modelled range sits inside the widely-cited eight to thirteen band, and the exact assumption is shown in the tool.

What it does not know

This is an estimate, not a promise. It assumes you grade honestly and study every day. A skipped day dumps its reviews onto the next one, and a lot of Again presses will push your real load above the line. Finishing the deck here means introducing every card by your date; the reviews carry on for weeks after that last new card. The point of the numbers is to set that expectation before you feel it.
