Result interpretation
Bond price is the present value of scheduled coupons and face value repaid at maturity. Below face is a discount, above face a premium, and approximately equal to face is par.

Formula
Price equals the present value of each coupon and final face value discounted at the required yield per period; N is remaining payment periods.
Formula variables
Face is principal repaid at maturity; Coupon Rate is the nominal annual coupon rate; YTM is the nominal annual required yield; m is payments per year; Years is time remaining; N = Years × m is the number of payments. Coupon per period = Face × Coupon Rate ÷ m; discount rate per period = YTM ÷ m.
How coupon rate and YTM affect price
All else equal, a higher coupon rate raises each payment and price; a higher required yield discounts the same payments more and lowers price. When the two rates match, a standard fixed-coupon bond prices at par.
Discount, par, and premium bonds
A discount bond trades below face when required yield generally exceeds coupon rate; a par bond trades at face when the rates match; a premium bond trades above face when required yield is generally lower.
WORKED EXAMPLE
Example
- Enter 1,000 face value, a 5% coupon rate, 6% required yield, five years remaining, and semiannual coupons.
- Each coupon is 1,000 × 5% ÷ 2 = 25 for 10 periods. Discount each coupon and the final principal at 3% per period.
- Coupon PV is about 213.26 and principal PV about 744.09, totaling about 957.35. Below 1,000 face value, it is a discount bond.
Frequently asked questions
Why does a higher required yield lower price?
The same scheduled payments are discounted at a higher rate, reducing their present value.
Can I price a zero-coupon bond?
Yes. Set coupon rate to 0%; price then equals the discounted face value at maturity.
Does this include accrued interest?
No. It assumes valuation on a coupon date and prices full future coupons; it excludes accrued interest, taxes, default, and early redemption.
How do I infer yield from a market price?
Use the YTM calculator and enter the known market price.
