Formula to Determine NAV Recovery Period – Coin – Direct MF – beragampengetahuan – Beragampengetahuan

If NAV of my debt fund is growing at constant rate, how much time it will take to reclaim the same NAV after a sudden drop of x%? Is there any mathematical formula to calculate this? Got below answer from Google Bard, but not sure, if it is correct.

Time = (1 + x%) / (Growth rate) – 1

Derivation:
NAV = Initial NAV * (1 + Growth rate) ^ Time
(NAV / Initial NAV) = (1 + Growth rate) ^ Time
Time = log((NAV / Initial NAV)) / log(1 + Growth rate)
Time = (1 + x%) / (Growth rate) – 1
