Presets
A bond's price moves opposite to yields, and duration measures how much. Modified duration approximates the percent price drop for a 1% rise in yield — longer maturities and lower coupons mean higher duration and bigger swings. Educational tool, not financial advice.

Governing equation
Reading this result: Coupon equals yield, so the bond prices right at par — yet its 7.7-year modified duration still exposes it to rate swings.
