How many values (numbers) are in your input data array? 240 x 144, in format longitude vs. time
How many values (numbers) are needed to build each term on the left? 144 for EOFs, 240 for PCs
If 5 EOFs capture most of the data's variance, how much smaller (in the above sense) is the EOFxPC representation compared to the full data set? 240 * 144 - (240 + 144) * 5
