Formulas Used:
Projected Retention for each language:
\( R_p = R_c \times e^{-\lambda \times t / i} \)
Where \( R_c \): current retention (%), \( \lambda = 0.05 \) (decay constant), \( t \): projection days, \( i \): interval days (1 daily, 7 weekly, 30 monthly).
Retained Words: \( W_r = W_l \times R_p / 100 \)
Avg Retention: Weighted average across languages.
Decay Rate: \( (R_c – R_p) / t \times 100 \) (avg % per day).
