Bond Pricing Basics
Bond prices move inversely with interest rates. When market rates rise above the coupon rate, bonds trade at a discount. When rates fall below the coupon rate, bonds trade at a premium to face value.
What is the Bond Calculator?
The Bond Calculator evaluates fixed-income securities like Corporate Bonds or Treasury Bills. It determines the "Yield to Maturity" (YTM) and the current fair market price of a bond based on its coupon rate and prevailing market interest rates.
How It Works (Formula)
A bond pays out semi-annual "coupons" (interest payments) and then returns the original "par value" at maturity. The calculator runs a Present Value (PV) discount formula on every single future coupon payment, plus the final par payout, to determine what the bond is worth today.
$$ \text{Bond Price} = \sum \left( \frac{C}{(1+r)^t} \right) + \frac{F}{(1+r)^T} $$
Discounts all future coupons ($C$) and the final face value ($F$).
How to Use It
Enter the Face Value (Par Value) of the bond. Input the annual Coupon Rate and the years remaining until maturity. Finally, input the current market Discount Rate. The tool will output the absolute maximum price you should pay to buy the bond today.
