A coupon payment is the periodic interest paid by a bond issuer to bondholders. Coupon rate is fixed at issuance — it's the annual interest rate printed on the bond (e.g., 4.5%). Most US bonds pay semi-annually (every 6 months). Zero-coupon bonds pay no periodic interest — they.

Bond coupon payments are the "rent" you earn for lending money. A $1,000 Treasury bond at 4.5% pays $22.50 every 6 months like clockwork. With $33 trillion in US government debt, these payments represent the largest fixed-income market on Earth.
Coupon Payment Math
Annual coupon = Face Value × Coupon Rate. For semi-annual bonds, divide by 2. Example: $1,000 × 4.5% = $45/year → $22.50 every 6 months. The formula is simple; the predictability is what makes bonds attractive for income investors.
Semi-Annual Calculations
Most US bonds pay semi-annually. A 10-year bond pays 20 coupons. Each payment is half the annual coupon. Effective annual yield slightly exceeds the stated rate due to reinvestment: EAY = (1 + r/2)² − 1. For 4.5% semi-annual, EAY ≈ 4.55%.
Bond Types Comparison
| Bond Type | Typical Coupon | Tax Treatment |
|---|---|---|
| US Treasury | 4–5% | Federal tax only |
| Corporate | 5–6% | Fully taxable |
| Municipal | 2.5–3.5% | Often tax-exempt |
| High-Yield | 7–10% | Fully taxable |
| Zero-Coupon | 0% | Phantom income accrues |

Accrued Interest & Callable Bonds
When buying between coupon dates, you pay accrued interest to the seller. Callable bonds can be redeemed early by the issuer — you may lose future coupons if rates fall. Higher coupons on callables compensate for this risk.
Frequently Asked Questions
What is a coupon payment?
A coupon payment is the periodic interest paid by a bond issuer to bondholders. The term dates from physical bond certificates with detachable coupons that investors clipped to redeem. Today it's electronic, but the name remains. For a $1,000 bond at 4.5%, you receive $22.50 every 6 months (semi-annual) — like clockwork rent for lending your money.
What is the difference between coupon rate and yield?
Coupon rate is fixed at issuance — it's the annual interest rate printed on the bond (e.g., 4.5%). Yield reflects your actual return based on what you paid. If you buy at par, coupon rate equals yield. Buy at a discount and yield exceeds coupon rate; buy at a premium and yield is lower. Yield to maturity (YTM) accounts for price, time to maturity, and reinvestment.
Semi-annual vs annual coupon payments — which is better?
Most US bonds pay semi-annually (every 6 months). A 4.5% coupon on $1,000 = $45/year, paid as $22.50 twice. European bonds often pay annually. Semi-annual gives earlier cash flow and slightly higher effective yield from reinvestment. Compare using effective annual yield: EAY = (1 + r/2)^2 - 1 for semi-annual.
How do zero-coupon bonds work?
Zero-coupon bonds pay no periodic interest — they're issued at a deep discount and mature at face value. The difference is your return. For tax purposes, the IRS requires reporting 'phantom income' each year on accrued interest, even though you receive nothing until maturity. Popular in retirement accounts where tax deferral matters.
What is accrued interest when buying bonds?
When you buy a bond between coupon dates, you pay the seller accrued interest — the portion of the next coupon they earned but haven't received. Formula: Face Value × Coupon Rate × (Days since last payment / Days in period). At the next coupon date, you receive the full payment; the accrued amount compensates the seller fairly.
What are callable bonds and how do they affect coupon payments?
Callable bonds let the issuer redeem the bond before maturity at a call price. If rates fall, issuers may call to refinance at lower rates — you lose future coupon payments. Callable bonds typically offer higher coupons to compensate. Check the call schedule: some are non-callable for 5–10 years (call protection).
