How do daily new-word rates and limits affect your study time?

The most common reason learners abandon spaced repetition is setting their daily new-word rate too high during the first week. Taking on new vocabulary feels manageable initially because the true workload of a new word does not arrive on the day it is learned—it arrives as accumulated reviews over subsequent weeks. By the time the daily review queue becomes overwhelming, the decision that caused it occurred weeks in the past and is rarely recognized as the source of the problem. Learners often conclude that spaced repetition is too demanding and stop studying altogether.

Tomaru structures its daily load settings to make the long-term cost of new vocabulary visible before you commit to a daily pace.

How do you choose a daily new-word rate?

Tomaru offers three preset rates alongside a customizable setting:

• Easier preset: 5 new words per day.
• Normal preset (Default): 10 new words per day.
• Harder preset: 20 new words per day.
• Custom rate: Adjust anywhere from 5 to 100 new words per day, in increments of 5.

The daily review limit is not an independent dial. In Tomaru, your review limit derives directly from your chosen new-word rate. Daily review load is a mathematical consequence of how fast you introduce new vocabulary, so adjusting your new-word rate automatically updates your daily review queue limit.

How does daily rate impact total study time?

Before you lock in a new-word rate, Tomaru estimates how much time your daily reviews will require. Increasing your daily new-word rate does not scale your study time linearly:

Learning 10 new words a day is not twice the work of 5. Anyone who has abandoned a vocabulary tool after a few weeks has likely encountered this steep curve without realizing how review accumulation works.

What other settings influence daily workload?

Two additional factors alter your total daily review volume:

• Target retention rate: Choosing a higher target retention setting increases the frequency of card reviews, requiring more time per day to maintain the same new-word pace.
• Target completion dates: If you are studying for a specific deadline, you can specify an end date and allow Tomaru to calculate the required daily new-word rate for you.

Related questions

Why does doubling my new-word rate more than double my daily study time?

Every new word generates multiple subsequent reviews over weeks and months. Taking on 20 words a day creates a compounding backlog of recurring reviews, drastically expanding your daily study time compared to a 10-word pace.

Can I change my daily new-word rate after starting a list?

Yes. You can adjust your daily new-word rate at any time in your study settings, and your daily review limit will automatically update to match without affecting your accumulated review history.

Is the review limit calculated automatically?

Yes. Tomaru derives your review limit from your selected new-word rate to ensure your queue reflects the true long-term workload required by your current learning pace.
