How to Calculate My Share While Exiting a Profitable Business Partnership?

Hi everyone, Two years ago, my friend and I started a boutique as a partnership, and we invested ₹848,440 together for shop setup and stock. The shop includes: Gypsum ceiling Lighting Electrical work Cash counter 3 shelves A display table A trial room Front glass Other necessary items. The business has been profitable until now, but I’ve decided to leave the partnership. How should we calculate the amount my friend should pay me for my share? I understand that depreciation needs to be considered for the shop setup. Can someone guide me on how to calculate it accurately? Also, how can we estimate the salvage value of these items? Thank you in advance for your advice!
