What Bond Calculator does

The Bond Calculator on Calculator.net provides two distinct tools for fixed-income analysis. The first computes standard bond parameters—price, yield, and time to maturity—when a bond is issued or traded on the coupon date. The second, more specialized calculator values bonds not traded on the coupon date, outputting the dirty price, clean price, accrued interest, and days since the last payment. Both tools require users to input face value, yield, annual coupon rate, and time to maturity, with additional options for coupon frequency and day-count conventions. The site presents these as separate, side-by-side calculators with clear headings and default settings, making it easy to compare standard pricing with accrued-interest adjustments.

Questions

Bond Calculator FAQ

What is the difference between the clean price and dirty price shown by the calculator?
The clean price is the quoted bond price excluding accrued interest, while the dirty price includes accrued interest accumulated since the last coupon payment. The calculator provides both values for bonds not traded on the coupon date.
How does the coupon frequency setting affect the bond price calculation?
Selecting annually, semiannually, quarterly, or monthly adjusts how the annual coupon rate is divided and applied across payment periods, which impacts the present value calculation and final price output.
Can this calculator determine yield to maturity if only the bond price is known?
The primary calculator requires four of five inputs (face value, yield, time to maturity, and annual coupon) to solve for the fifth value, so it can compute yield to maturity when price is provided instead.
What day-count conventions are available and when should each be used?
The tool offers 30/360, Actual/360, Actual/365, and Actual/Actual conventions. 30/360 assumes 30-day months and 360-day years; the Actual variants use real day counts, with Actual/365 using a 365-day year and Actual/Actual using actual days in both numerator and denominator.
