Flashcard Study Plan Calculator
Calculate how many flashcards to study daily using spaced repetition.
Plan your study schedule for exams and language learning.
Flashcard Study Planning uses spaced repetition principles to help you learn and retain a large number of flashcards before a deadline.
The core challenge: You need to learn N cards before an exam. Each card needs multiple review sessions to move into long-term memory.
Spaced repetition schedule (Leitner system):
- Box 1 (new cards): review daily
- Box 2: review every 2 days
- Box 3: review every 4 days
- Box 4: review every 8 days
- Box 5 (mastered): review every 16 days
How many reviews per card: On average, a card needs 5-7 successful reviews before it is considered “mastered.” Not every review is successful, so expect about 8-10 total encounters per card on average.
Daily workload formula:
New Cards Per Day = Total Cards / Available Study Days
Daily Reviews = New Cards Per Day + (Cards in Review Queue × Average Success Rate Adjustment)
As your collection grows, review load increases:
- Week 1: mostly new cards, few reviews
- Week 2-3: balanced new and review cards
- Final weeks: mostly reviews, few new cards
Recommended study intensity:
- Light study: 10-20 new cards per day
- Moderate study: 20-40 new cards per day
- Intensive study: 40-60 new cards per day
- Maximum recommended: 60 new cards per day (beyond this, retention drops significantly)
Time estimates:
- Each new card takes about 30-60 seconds to learn initially
- Each review takes about 10-20 seconds
- Total daily study time = (New cards × 45 seconds) + (Reviews × 15 seconds)
The forgetting curve: Without review, you forget approximately 50% of new information within 24 hours. The first review within 24 hours dramatically improves retention to 80%+. Subsequent reviews at increasing intervals push retention above 90%.
