Equivalent units are used to apportion cost between completed units and work in progress. They represent notional whole units which represent incomplete work.

Equivalent units = Degree of work done * units of inventory

Valuation of inventory suing weighted average method

Under this method, no distinction is made between opening inventory and units newly introduced in the current period when accounting for completed units.

All completed units are assumed to be items for which work were started and completed this period, i. e 100% work is assumed to be done in the current period.

We can work out the he equivalent units of Nabais Corporation as follows

Items workings Equivalent units

Completed units 32,200 * 100% 32,200

Closing inventory 1,800 * 60% = 1,080

Equivalent units 33280

Total equivalent unit for conversion cost =

=32,200 + 1,080

=33,280 units
