Theta decay

Sun, 21 Jun 2026 00:00:00 +0000

Theta is the option Greek that measures how much premium an option loses for each calendar day that passes, holding the underlying price and implied volatility constant. It is the daily cost of time. Theta is negative for an option buyer, who watches the premium erode every day, and works in favour of an option writer, who collects that decay; the time value of an option falls to zero at expiry, and theta tracks the pace of that fall. The decay is not steady: it accelerates sharply in the final days of a contract.

Option Greeks are sensitivity measures that quantify how an option’s price changes in response to changes in the underlying price, time, implied volatility, and interest rates. Kite displays Greeks in its options chain Greek tab; Sensibull shows net Greeks for multi-leg strategies. This guide explains how to find and interpret each Greek and how to use them to make better trade decisions.

For the options chain navigation itself see How to use the options chain on Kite . For applying Greeks to a full strategy see How to build an options strategy on Sensibull .
