Bond Calculators

MiniWebtool’s Bond Convexity Calculator measures curvature in a bond’s price–yield relationship. Coupon terms, maturity, and yield produce convexity and a comparison of duration-only, curvature-adjusted, and repriced results for a chosen yield shock.

See both cash-flow timing and yield sensitivity in MiniWebtool’s Bond Duration Calculator (Macaulay & Modified). Enter coupon terms, maturity, and yield to calculate the two duration measures and inspect a modeled price response to a yield change.

Enter face value, purchase price, and days to maturity in MiniWebtool’s Bond Equivalent Yield Calculator to get bond equivalent yield for a discount security.

Explore Current Yield, Yield to Maturity (YTM), and Yield to Call (YTC) with MiniWebtool’s Bond Yield Calculator, including step-by-step formulas, cash flow analysis, and interactive visualization.

MiniWebtool’s Bond Yield to Maturity Calculator takes current bond price, par value, annual coupon rate, and years to maturity to calculate yield to maturity along with expected capital gain or loss.

Explore US Series I savings bond growth with MiniWebtool’s I Bond Calculator. It calculates composite-rate interest accrual and shows the effect of the three-month interest penalty on eligible redemptions before five years, using the rate assumptions supplied.

Estimate a Treasury bill purchase with MiniWebtool’s T-Bill Calculator. Enter face value, term, and a discount rate or price to compare dollar return, yield conventions, and a modeled tax-equivalent yield.

MiniWebtool’s Treasury Inflation-Protected Securities (TIPS) Calculator models US TIPS principal and coupon payments under an assumed inflation rate. Compare the schedule with a nominal Treasury and inspect the maturity deflation floor.

Enter face value, current price, and years to maturity into MiniWebtool’s Zero Coupon Bond Calculator to calculate yield to maturity and present value for zero coupon bonds.
