Calculation of goodwill under super profit basis:
Net profit of last three years:
1st year = Rs. 60000 - Rs. 24000 (24000 being annual salary of rs. 12000 to each partner) = Rs. 36000
2nd year = Rs. 72000 - Rs. 24000 = Rs. 48000
3rd year = Rs. 84000 - Rs. 24000 = Rs. 60000
Average profit = Total net profit/ No. of years
Average profit = Rs. (36000 + 48000 + 60000)/3 years
Average profit = Rs. 144000/ 3 = Rs. 48000
Normal profit = Capital employed * rate of interest
Normal profit = Rs. 200000 * 15% = Rs. 30000
Super profit = Average profit - Normal profit
Super profit = Rs. (48000 - 30000) = Rs. 18000
Goodwill = Super profit * No. of year's purchase
Goodwill = Rs. 18000 * 2 years
Goodwil = Rs. 36000
