Debenture Calculator

A debenture is a debt instrument issued by a company to raise funds, paying investors a fixed coupon rate over a set tenure — distinct from a government bond, which is issued by the sovereign rather than a company.

Secured debentures are backed by specific company assets, giving investors a claim on those assets if the company defaults. Unsecured debentures have no such backing and carry higher risk, which typically comes with a higher coupon rate to compensate.

The underlying yield math is the same, but this tool is framed specifically around company-issued debentures — including the secured/unsecured risk distinction — while the Bond Yield Calculator is generic to any bond, government or corporate.
