How this calculator works

Treasury Bill

This is a simplified educational estimate. Actual Treasury bill pricing can use discount and yield conventions that differ from this calculation.

01

Formula

Estimated return = Investment × Annual yield × Term days ÷ 365.

02

Simple example

Enter Rs. 1,000,000, a 364-day term, and the annual yield you want to test to see estimated proceeds.

FAQ

Frequently asked questions

Does this show the current auction yield?+

No. Enter a yield from a source you trust; this calculator does not retrieve live market data.

Will actual purchase proceeds match exactly?+

Not necessarily. Actual prices depend on the quotation, settlement, discount or yield convention, and applicable costs.
