Calculator

Settle on a purchase date, choose a pricing mode, and either generate a regular coupon schedule or switch to a custom dated-cash-flow engine for exotics.

Tip: the regular schedule is editable below. Change any coupon date or amount, or switch to custom cash flows to represent step-ups, amortizers, callable bonds, puts, sinking funds, or any other exact-date structure.

Exact dated cash-flow schedule

Each row can be a coupon, principal, call/put redemption, amortization installment, fee, or any bespoke cash flow.

Bond cash flow schedule: date, amount, label, type and notes for each cash flow.
Date	Amount	Label	Type	Notes	Action

Embedded option scenarios

Add call or put dates and exercise prices to compute scenario yields and a simple yield-to-worst. For fully path-dependent exotics, use custom cash flows directly.

Embedded call and put option scenarios: date, option type, strike price and notes.

How to Use This Bond Calculator

A complete guide to modeling fixed-income valuations, cash flows, and risk metrics.

Understanding the Valuation Engine

This professional tool utilizes an exact-dated cash-flow engine to evaluate both vanilla bonds and complex fixed-income structures. To calculate accurate pricing and yield metrics:

Bond Setup: Enter the settlement (purchase) date, maturity date, and face value. Select your coupon rate and payment frequency (Annual, Semiannual, Quarterly, Monthly, or Zero Coupon).
Market Conventions: Select the applicable day-count convention (e.g., ACT/ACT, 30/360) and any settlement lag required by your specific market.
Target Metric: Use the primary solve mode to either input a clean price to "Solve YTM" or input a market YTM to "Solve price."
Exotic Cash Flows: For non-standard bonds, use the "Exact dated cash-flow schedule" to manually input irregular stubs, step-up coupons, or amortizing principal payments.
Analyze Outputs: Click "Calculate" to generate the present value (clean and dirty prices), accrued interest, and key interest rate risk metrics like Modified Duration and Convexity.

Frequently Asked Questions (FAQ)

What is the difference between a bond's clean and dirty price?

The clean price is the quoted market price of a bond, excluding any interest that has accrued since the last payment date. The dirty price (or invoice price) is the total amount the buyer actually pays, which equals the clean price plus the accrued interest.

Is a higher Yield to Maturity (YTM) always better?

Not necessarily. A higher YTM usually indicates higher risk. Investors demand a higher risk premium (higher yield) for bonds with lower credit ratings, higher default probabilities, or less liquidity. You must weigh the attractive yield against the creditworthiness of the issuer.

How does Modified Duration measure risk?

Modified Duration measures a bond's price sensitivity to interest rate changes. For example, if a bond has a modified duration of 5.0, a 1% (100 basis point) increase in market interest rates will cause the bond's price to drop by approximately 5%.

What is Yield to Worst (YTW)?

Yield to Worst (YTW) is the lowest potential yield an investor can receive on a callable bond (assuming the issuer does not default). It is found by calculating the yield to every possible call date and comparing them against the yield to maturity, then selecting the lowest figure.

What role does Convexity play in bond pricing?

Convexity measures the curvature in the relationship between bond prices and interest rates. Because Modified Duration is just a linear estimate, it becomes inaccurate for large yield changes. Convexity adjusts for this, showing that bond prices fall less than duration predicts when rates rise, and rise more when rates fall.
