Sundaram Tools Ltd. has a machine setup cost pool of Rs 3,60,000 for the year, with the number of setups as the cost driver. Product P required 40 setups and product Q required 20 setups. Total setups for all products were 120. P produced 2,000 units. What is the setup cost per unit of P under ABC?

The setup cost per unit of P is Rs 60. The rate is Rs 3,60,000 divided by 120 setups, which is Rs 3,000 per setup. P's 40 setups cost Rs 1,20,000, and dividing by 2,000 units gives Rs 60.

Explanation

Rate per setup = 3,60,000 / 120 = Rs 3,000. Setup cost of P = 40 x 3,000 = Rs 1,20,000. Per unit = 1,20,000 / 2,000 = Rs 60. Rs 90 would result from wrongly using only the P and Q setups (60) as the base: 3,60,000/60 = 6,000 x 40 = 2,40,000, then /2,000 = Rs 120, so Rs 120 is that error, and Rs 90 is not supported by the data.
