About this calculator
A spot rate is the annualized yield implied by a single zero-coupon bond — a bond with no periodic interest payments that simply pays its face value at maturity, purchased today at a discount. Because there are no coupons to complicate the cash flow, the spot rate solves directly from (Face Value ÷ Current Price)^(1/n) − 1, where n is the number of years to maturity, giving the compound annual growth rate an investor earns by holding to maturity.
Spot rates for different maturities are the building blocks fixed-income analysts use to construct a yield curve — a process called bootstrapping, where spot rates derived from zero-coupon (or stripped) Treasury securities at each maturity are used to discount and price coupon-bearing bonds correctly. This calculator takes a bond’s face value, current price, and years to maturity to compute its annualized spot rate along with the total return over the holding period.
