As the unit price is increasing the method which yields the highest gross profit would be FIFO.But in some cases the income is overstated as the beginning inventory is too old to account for . Similarly Lifo gives lower net income but that too is not very beneficial when the inventory is almost obsolete.

The average method gives a measure in between FIFO and LIFO.
