Calculate the periodic interest coupon payment of a bond.

💵

Calculation Parameters

Specify your inputs below.

Calculated Result

Annual Total Coupon Income $450.00
Periodic Coupon Interest Payment $225.00
💡

Expert Tip

Most corporate and government bonds issue coupon interest payments semi-annually (2 times per year).

How this Calculator Works

This calculator computes the cash payment amount received by bondholders as interest. It processes the bond's face value, nominal coupon rate, and payment frequency (e.g. semiannual or quarterly). Fixed-income investors use it to map portfolio cash flows.

Formula & Methodology

Coupon Payment = (Face Value * Coupon Rate / 100) / Frequency - Face Value is the par value of the bond. - Coupon Rate is the nominal annual interest rate. - Frequency is the number of coupon payments per year.

Step-by-Step Calculation Example

Here is a step-by-step example showing how the calculations are performed:

You own a bond with a face value of $5,000 and an 8% coupon rate that pays semiannually (frequency = 2). 1. Calculate annual coupon: $5,000 * 0.08 = $400. 2. Divide by frequency: $400 / 2 = $200. Result: The periodic semiannual interest coupon payment is $200.

FAQ

How does bond duration measure interest rate risk?
Modified duration estimates the approximate percentage change in a bond's price for a 1% (100 bps) shift in interest rates. Higher duration indicates greater price sensitivity to rate moves.
What is Tax-Equivalent Yield (TEY) for municipal bonds?
Tax-Equivalent Yield = Municipal Tax-Exempt Yield / (1 - Marginal Tax Rate). It shows the pre-tax yield a taxable bond would need to equal the after-tax yield of a tax-free municipal bond.
Can fixed income calculators guarantee bond trading outcomes?
No. Bond pricing models assume clean compounding yields and fixed reinvestment rates. Secondary market prices fluctuate based on liquidity, credit rating revisions, and market interest rate movements.
