About the Bond Calculator
This bond calculator values a fixed-rate coupon bond using face value, coupon rate, yield to maturity, time to maturity, and coupon frequency. It can also estimate yield to maturity from a market price, then compare the clean price, dirty price, accrued interest, coupon payments, and price sensitivity.
The calculator follows the common bond-pricing workflow: future coupon payments and the maturity value are discounted back to today using the required yield. When a bond trades between coupon dates, accrued interest is added to the clean price to estimate the dirty price, which is closer to the invoice price paid by the buyer.
Face value and coupon
Face value is the amount repaid at maturity. Coupon rate determines the annual interest paid based on face value and payment frequency.
Yield to maturity
Yield to maturity estimates the annualized return if the bond is purchased at the modeled price and held until maturity, assuming payments are received as scheduled.
Clean vs. dirty price
Clean price excludes accrued interest. Dirty price adds accrued interest from the last coupon date to settlement, which matters when a bond trades between coupon dates.
How to use this calculator
Choose whether to solve price or yield. Enter face value, market price if needed, coupon rate, yield, years to maturity, coupon frequency, and settlement-date assumptions. Review the result cards, cash-flow mix, sensitivity chart, and cash-flow schedule.

Bond Calculator FAQ
Answers about key inputs, outputs, charts, fees, return assumptions, and interpretation.
What does a bond calculator estimate?
It estimates bond price, yield to maturity, clean price, dirty price, accrued interest, coupon payment, current yield, and basic cash-flow schedule values.
What is face value?
Face value, also called par value, is the principal amount the issuer agrees to repay when the bond matures. Coupon payments are usually calculated from face value.
What is yield to maturity?
Yield to maturity is the annualized return implied by the bond price, coupon payments, face value, and time to maturity if the bond is held to maturity.
What is the difference between clean price and dirty price?
Clean price excludes accrued interest. Dirty price includes accrued interest and is closer to the amount actually exchanged at settlement when a bond trades between coupon dates.
Why does coupon frequency matter?
Coupon frequency changes the number and size of coupon payments. Semiannual coupons are common, but annual, quarterly, and monthly schedules can produce different present values.
Does this account for credit risk or call features?
No. It models a fixed-rate coupon bond. It does not adjust for credit quality, liquidity, supply and demand, embedded calls, puts, tax treatment, or changing market conditions.
