This calculator allows you to determine the price of a Treasury Bond that is re-opened or sold on the secondary market before its maturity date. Enter the bond’s coupon rate, issue date, and maturity date to estimate its current value. The re-discount price is derived using a coupon-based rediscounting rate, calculated from the prevailing market rate plus the applicable penalty margin. Kindly note that, in determining final prices, the Central Bank may alternatively apply a market yield-based rediscounting rate depending on prevailing market conditions.
