In finance, duration is a measure of how the price of a fixed-income instrument responds to a change in interest rates. It is used to compare rate risk across bonds and to construct hedges, and is often paired with convexity and the price value of a basis point. Duration-based estimates work best for small, parallel shifts in the yield curve.

Macaulay duration is the present-value-weighted average time to the cash flows and links payment timing to interest-rate risk.
