Daily review budget calculator

Why review volume scales with level

New WaniKani users see a misleadingly light review load. At level 1 there are maybe 50 reviews a day, you cruise through them in ten minutes, and the SRS feels easy. The problem is that the SRS is a queue: every item you start eventually cycles back, and the queue compounds.

By level 10 you typically have several hundred items churning through Apprentice and Guru. By level 30 the backlog is significantly larger - more items at long intervals (Master, Enlightened) means more items eventually return for review on any given day. The volume plateaus once burned items start leaving as fast as new lessons enter, but for most users that plateau lands somewhere between 200 and 350 reviews per day.

The calculator anchors its estimate to the mid-level of your run, since that's roughly where you'll spend the most days. It also adjusts for pace: if you stretch each level over three or four weeks, fewer lessons enter the queue per day, so daily review volume drops roughly in proportion.

Approximate review volume by level band

These are rough ranges drawn from community-reported daily review counts. Individual numbers vary based on accuracy, lesson cadence, vacation mode, and whether you do lessons in big batches or trickle them in:

• Levels 1-5: 30 to 100 reviews per day
• Levels 6-10: 80 to 180 per day
• Levels 11-20: 120 to 250 per day
• Levels 21-30: 150 to 300 per day
• Levels 31-40: 160 to 330 per day
• Levels 41-50: 170 to 360 per day
• Levels 51-60: 180 to 400 per day

The high end of each band assumes you're running at 7-day pace with a tight Apprentice churn. The low end assumes a 30-day relaxed pace with most items at Master or Enlightened. Drop a pace into the calculator above and it picks the right point in the band.

The 300-review danger zone

Past about 300 reviews per day, three things tend to happen. First, accuracy drops - you're tired by the time you finish, and tired-brain mistakes drag items backwards through the SRS. Second, leeches build up: items that you keep getting wrong cycle in Apprentice forever, eating proportionally more of your daily count. Third, real life intervenes - one missed day at 300 reviews per day becomes 600 reviews tomorrow, and the queue starts feeling like a punishment.

If the calculator above suggests more than 300 reviews per day at your target pace, that's a strong signal to either slow the pace or take fewer lessons at a time. WaniKani's SRS rewards consistency far more than heroic pushes; you want a daily budget you can hit on a bad day, not your best day.

What "10 seconds per review" assumes

The time estimate uses 10 seconds per review as a baseline, which is roughly what a warmed-up user averages on a smartphone. Brand-new users tend to take 20 to 30 seconds per review while they're still learning the typing patterns. Power users with keyboard shortcuts and a tight typing rhythm get down to 5 or 6 seconds.

That means a 200-review day is a real 30 minutes most days and could stretch to an hour on a tough one. Plan accordingly - block the time on your calendar rather than assuming you'll find it.
