You can use indicative yields to compare different government securities (G-Secs), but your actual returns will depend on auction prices.
Understanding indicative yields
Zerodha calculates indicative yields based on the last traded price of government securities and presents them as annualised figures. You can use these yields to compare different G-Secs before making investment decisions.
However, your actual yield will depend on the weighted average price discovered during the auction, not the indicative yield shown.
