Bond Calculators

Calculate a bond's convexity to measure price sensitivity to large yield moves. Get Macaulay duration, modified duration and convexity, plus a side-by-side duration-only versus duration-plus-convexity price prediction.

Compute Macaulay duration, modified duration, DV01, and PV half-life for any coupon bond. See duration as a balance-point of present-value cash flows, predict the price change for a custom yield shock, and walk through every formula step.

Calculate bond equivalent yield (BEY) with step-by-step formula breakdown, visual comparison charts, multiple bond analysis, and investment insights for treasury bills, commercial paper, and discount securities.

Calculate bond yields including Current Yield, Yield to Maturity (YTM), and Yield to Call (YTC) with step-by-step formulas, cash flow analysis, and interactive visualization.

Calculate bond yield to maturity (YTM) with step-by-step formula breakdown, cash flow visualization, investment analysis, and comprehensive bond metrics including current yield and capital gain/loss.

Calculate the composite rate, semiannual interest accrual and 3-month early-redemption penalty for US Series I savings bonds. See the bond grow month by month, what you forfeit before 5 years, and your penalty-adjusted real yield.

Calculate the discount purchase price, dollar return and yield of a US Treasury bill from 4 to 52 weeks. Get the bank discount rate, coupon-equivalent yield, effective annual yield, and the tax-equivalent yield a taxable CD must beat.

Calculate the inflation-adjusted principal, growing coupon payments, real yield and deflation-floor protection of US TIPS. See how each coupon ratchets with CPI and how the principal escalator compares with an ordinary fixed-rate Treasury.

Calculate zero coupon bond present value, yield to maturity (YTM), and comprehensive investment metrics with step-by-step formulas, interactive charts, and bond comparison analysis.
