# WIP Costing

Registered Posts: 465 Dedicated contributor ? ? ?
Hi,

Can anyone explain to me how Work in Progress Costing works, I cannot get my head around it when it states that eg labour is 75% complete and Materials 100%?

Thanks

As a cool cat, I'm sure you're keen on good cat food.

The process we are going to look at is cooking, later on it will go to canning.
In cooking the staff collect the raw materials from the stores, cut it up, put it in to big pans, cook it for a few hours, then pour it out into containers that are then taken to the canning department.

In April lots of material went into cooking department. 20,000kgs costing £5,000
The labour cost for the hours worked was £9,500

We produced 16,000 kgs that were transferred to canning
on 30 April we has 4,000kgs still cooking

So 16,000 completed, 4,000 closing work in progress

Labour time is 75% cutting/preparing the raw materials
and 25% pouring out the cooked food into containers for transfer to canning

So all the materials in the 4,000kgs of WIP have been used (100% materials)
but only 75% of the labour needed to complete the job (the next 25% will be needed before the 4,000 kgs can be transferred)

Calculating the cost per equivalent unit

Do this on an input by input basis, then add the values together.
1. Materials cost per unit
Total cost of materials £5,000
Finished goods produced 16,000 + Closing WIP 4,000 (100%) = 20,000
....................................................£5,000 ..... = £0.25 per unit
................................................20,000units
2. Labour cost per unit
Total cost of labour £9,500
Finished goods produced 16,000 + Closing WIP 4,000 (75%) = 19,000
....................................................£9,500 ..... = £0.50 per unit
................................................19,000units
3. Total cost per equivalent unit produced
Materials £0.25
Labour...£0.50
............£0.75
