Can I use a calculator shortcut for Macaulay duration if I understand the cash-flow weighting?
I can set up bond cash flows on the calculator, but I am worried I am just pressing keys without understanding duration. What should I know conceptually before trusting the shortcut?
Yes, but only if you can explain what the output represents. Macaulay duration is the present-value-weighted average time to receive the bond's promised cash flows. A calculator shortcut is just a faster route to the same timing measure; it is not a replacement for knowing that earlier cash flows shorten duration and later cash flows lengthen it.
The concept check is simple. For an otherwise similar bond, a higher coupon should usually have lower Macaulay duration because more present value is received earlier. A zero-coupon bond should have Macaulay duration equal to maturity. If your calculator result violates those basic relationships, the input setup is probably wrong.
