Spaced Repetition Calculator
Calculate optimal SRS intervals using the spaced repetition algorithm for effective long-term memorization.
SRS Parameters
Higher = longer intervals (2.5 is default)
SM-2 Algorithm
Interval(n) = Interval(n-1) x EaseFactor
First interval: 1 day, Second: 6 days
Final Interval
94 days
Total span: 153 days

About Spaced Repetition
How It Works
Spaced repetition optimizes review timing based on the forgetting curve. Items are reviewed just before you would forget them, strengthening long-term memory.
Ease Factor Tips
Start with 2.5 for new material. Increase for easy content, decrease for difficult material. Never go below 1.3 to avoid burnout.
