Example 3: Using the same video equipment from the previous example, calculate the amount of depreciation of the
fourth year using SOYD, but now assume that the equipment was bought in February.
Figure 8
Solution: The diagram in Figure 8 helps building the solution. The fourth year is calculated by adding 1/12 of the third
depreciation year to 11/12 of the fourth depreciation year. If data from previous example has not been
changed yet, the following keystroke sequence can be used:
3 fÝ 12 z ?0
Figure 9
This is the depreciation amount for 1/12 of the 3
rd
year, and it is stored in R
0
. Now calculate 11/12 of the
fourth depreciation year, add it to R
0
and retrieve the accumulated value:
4 fÝ 11 § 12 z ?+0 :0
Figure 10
Answer: The amount of depreciation for the fourth year is $1,962.74 given that the first depreciation year was only
11 months long.
