Consider a bond that has a coupon rate of 7.5%, five years to maturity, and is currently priced to yield 7.5%. Calculate the following: Macaulay duration Modified duration Percentage change in price for a 1% increase in the yield to maturity
| Period | Cash Flow | PV Cash Flow | Duration Calc |
| 0 | ($1,000.00) | ||
| 1 | 75.00 | 69.77 | 69.77 |
| 2 | 75.00 | 64.90 | 129.80 |
| 3 | 75.00 | 60.37 | 181.12 |
| 4 | 75.00 | 56.16 | 224.64 |
| 5 | 1,075.00 | 748.80 | 3,744.00 |
| Total | 4,349.33 |

=4349.33/1000 = 4.349
Modified duration = Macaulay duration/(1+YTM) = 4.349/(1+0.075)
=4.05
with 1 % increase in YTM
Modified duration prediction = -Mod_Duration*Yield_Change
-4.05*1 = -4.05%
