A step-by-step walk for bond duration starts on FinanceLearn: read the identity, open the calculator, use the checked default, then change the inputs. The published example is independently re-derived. A numbered list in a chat is not a source.

The steps

1. Open the bond duration calculator. 2. Read the formula. PV(CFt)PV(CF_t) is the present value of the cash flow at time tt in years, PP the price, yy the annual yield and kk the number of coupon periods a year. DV01 is modified duration times price over 10,000: the dollar change for a one basis point fall in yield. 3. Leave the defaults if you want the checked example, or type yours. 4. Read the result above the inputs. 5. If a pair is involved, open the matching compare page.

Why the order matters

Finance is full of arithmetic that looks right. The convention has to be named before the number is useful. The longer how-to is how to calculate bond duration.
