Bullet Bond
Bond structure that repays principal in one lump sum at maturity while paying coupon interest during the life of the issue.
A bullet bond is a bond that repays principal in one lump sum at maturity rather than paying principal down over time. Coupon interest is usually paid periodically during the life of the bond, but the face value stays outstanding until the maturity date.
That final principal payment is the defining feature. A bullet bond can be fixed-rate, floating-rate, taxable, tax-exempt, secured, unsecured, callable, or noncallable; “bullet” describes scheduled principal timing, not every risk in the bond.
Cash-Flow Pattern
In a plain coupon-paying bullet structure, the investor receives coupons during the bond’s life and receives par value at maturity.
For a standard coupon-paying bullet bond, price reflects the present value of coupons plus the final principal repayment:
Where P is the bond price, C is each coupon payment, F is face value, y is the yield per period, and n is the number of periods to maturity.
Why It Matters
Bullet bonds are the baseline structure for much of fixed-income analysis because the cash flows are clean: coupons along the way, principal at the end.
They matter for:
- Yield to Maturity, because the final principal payment is part of the yield calculation
- Duration, because principal remains outstanding until maturity
- refinancing risk for issuers, because the principal wall arrives on one date
- reinvestment planning for investors, because principal is returned all at once
- benchmark comparison, because many Treasury and corporate benchmark issues are bullet-like
- credit analysis, because exposure to the issuer does not step down through scheduled amortization
The main tradeoff is simplicity versus maturity concentration. The structure is easier to value than an amortizing structure, but the issuer must be able to repay or refinance the full principal at maturity.
Practical Example
Suppose an investor buys a 5-year bond with $1,000 face value and a 5% annual coupon.
| Year | Coupon | Principal | Ending scheduled principal |
|---|---|---|---|
| 1 | $50 | $0 | $1,000 |
| 2 | $50 | $0 | $1,000 |
| 3 | $50 | $0 | $1,000 |
| 4 | $50 | $0 | $1,000 |
| 5 | $50 | $1,000 | $0 |
The coupons are spread through time, but principal stays outstanding until year 5. If interest rates rise before maturity, the market price can fall even though the scheduled principal repayment is unchanged.
Bullet vs. Related Structures
| Structure | Scheduled principal pattern | Investor question |
|---|---|---|
| Bullet bond | Principal due at maturity | Can the issuer repay or refinance the final amount? |
| Amortizing Bonds | Principal repaid gradually | How quickly is exposure reduced? |
| Serial Bond | Different maturities retire pieces of an issue | Which maturity is being priced or held? |
| Sinking Fund Provisions | Term maturity may be reduced by scheduled redemptions | How and when can bonds be selected for redemption? |
| Zero-Coupon Bond | No coupon; principal or accreted value at maturity | Is return from price accretion rather than coupon income? |
Do not use “bullet” as a synonym for “safe.” The principal schedule is only one part of the analysis.
Common Confusions
- Bullet does not mean zero-coupon. A bullet bond can pay regular coupons.
- Bullet does not mean noncallable. A callable bond may still have a scheduled bullet maturity if it is not called.
- Bullet does not mean short term. A bullet maturity can be near or far.
- Bullet does not remove credit risk. The issuer still must make coupon payments and repay principal.
What To Verify
Before treating a bond as a clean bullet exposure, verify:
- maturity date and final principal amount
- coupon rate, coupon frequency, day-count convention, and settlement date
- call, put, conversion, sinking fund, or extraordinary redemption provisions
- whether the bond is fixed-rate, floating-rate, inflation-linked, or zero-coupon
- credit rating, collateral, seniority, covenants, and issuer repayment source
- price, yield convention, accrued interest, and trade settlement terms
- whether the issue has multiple maturities, series, or CUSIPs that should not be blended
If a callable bullet bond is trading above par, yield-to-call or yield-to-worst may be more decision-relevant than yield-to-maturity.
Public Source Checks

- FINRA Bond Investing and Due Diligence: Practical due-diligence points including maturity, security provisions, yield, call status, tax treatment, and credit rating.
- FINRA Fixed Income Data: Public bond data and trade information for corporate, agency, and other fixed-income securities.
These public sources support the general bond-structure context. A trade-specific conclusion still requires the prospectus, official statement, indenture, confirmation, pricing data, and position record.
