Applications
7 Enter annual coupon rate, press PMT.
8 Enter price (present value) of the bond, press PV.
9 Press   i (YTM) to obtain effective annual yield-to-maturity.
Note: If the time to maturity is less than six months, skip steps 1-6, then convert time to days and press n. Continue with step 7.
Sample Case: What is the yield-to-maturity of a 4% bond purchased at a price of 106.75 that matures in 9 years 10 months?

Sum-of-the-Years’ Digits Depreciation

This calculation finds the depreciation and remaining depreciable value for each year of an asset’s depreciable life when the beginning-ending periods, and the asset’s present value (less salvage value) are known. The formula uses the constant storage location, therefore, any value stored there will be destroyed when the final key (the one that triggers the result) is pressed. Information is entered as follows:
1 Enter beginning year number (e.g., year 1), press n.
2 Enter depreciable life of asset (in years), press n.
3 Enter present value of asset, press PV.
4 Press  , then press SOD (COMPUTE) to obtain beginning year’s depreciation.
5 Press x y to obtain remaining depreciable value.
6 Press x y, then press SOD to obtain beginning year’s depreciation.
7 Press x y to obtain remaining depreciable value.
8 Repeat Repeat steps 6 and 7 to obtain each subsequent year’s depreciation and remaining depreciable value until the asset is completely depreciated or until the number of iterations is equal to the depreciable life of the asset (in terms of years).
Note 1: You can bypass the remaining depreciable value calculation by skipping steps 5-8, and can obtain each subsequent year’s depreciation by pressing SOD repeatedly after completing step 4.
