Expert Tip

Buying bonds at a discount lowers the capital required to achieve your desired target coupon income flow.

How this Calculator Works

This calculator estimates the face value (par value) of bonds needed to generate a target monthly or annual income. It uses the bond's nominal coupon rate to determine required investment sizes. Retirees use it to build passive income streams.

Formula & Methodology

Needed Face Value = Target Annual Income / (Coupon Rate / 100) - Target Annual Income is the target interest cash flow required by the investor. - Coupon Rate is the annual interest rate paid by the bond (as a percentage).

Step-by-Step Calculation Example

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

An investor plans to generate $12,000 in annual income using bonds paying a 4% coupon. 1. Divide target income by coupon rate: $12,000 / 0.04 = $300,000. Result: The investor needs to purchase bonds with a total face value of $300,000.

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.
