Yield to maturity (YTM) is the single annualized rate that lines up a bond’s current price with its remaining coupons and face value at maturity—if you hold to maturity, reinvest coupons at the same YTM, and the issuer pays on schedule. Screeners at Fidelity, Schwab, Vanguard, and TreasuryDirect-style listings lean on YTM so you can compare a 3% coupon bought at a discount to a 5% coupon bought at a premium. It is a comparison tool, not a guaranteed personal return.
Duration and price risk still matter: Bond duration basics. Taxable vs tax-exempt comparisons: Municipal bond taxable-equivalent yield. Treasury maturity labels: Treasury notes vs bonds.
Coupon rate vs current yield vs YTM
| Measure | What it uses | What it misses |
|---|---|---|
| Coupon rate | Annual coupon ÷ face | Ignores the price you actually paid |
| Current yield | Annual coupon ÷ market price | Ignores gain/loss to par at maturity |
| YTM | Price, coupons, face, time to maturity | Assumes hold-to-maturity + reinvestment at YTM |
A bond with a high coupon can show a lower YTM than a discount bond if you paid a large premium for that coupon. Conversely, a low coupon bought cheap can show a higher YTM because part of the return is the climb to par—tax timing of that climb: Bond discount accretion and Bond premium amortization.
Assumptions baked into YTM
- You hold until maturity (no sale at a different market yield).
- Every coupon arrives on time and you reinvest at the same YTM (often unrealistic when rates change).
- The issuer does not default or force an early call (see Callable bond risks for yield-to-call / yield-to-worst).
- Quoted YTM is usually a bond-equivalent / semi-annual market convention—do not treat it like APY on a savings account without reading the screener’s footnote.
If rates fall and you sell early, your realized path can beat the original YTM. If rates rise or you sell into a wider credit spread, you can underperform it. YTM does not erase duration risk.
Worked example: two corporates on a Schwab ladder
Riley compares two taxable corporates for a brokerage ladder:
| Bond | Price | Coupon | Years to maturity | Stated YTM (illustrative) |
|---|---|---|---|---|
| A | $10,400 | 5.0% on $10,000 face | 8 | ~4.4% |
| B | $9,550 | 3.5% on $10,000 face | 8 | ~4.4% |
Same YTM band does not mean identical experience. Bond A pays more cash coupon each year but embeds premium amortization / lower interest for tax in many taxable accounts. Bond B pays less cash now and may accrete discount into taxable income. Riley also checks credit ratings, call features, and duration before deciding—not YTM alone.
For beginners building diversified exposure without single-bond homework, funds often beat one-off YTM shopping: Investing basics for beginners.
How to use YTM in practice
- Compare like with like: same tax status (taxable vs muni), similar credit quality, and similar maturity.
- On munis, convert to taxable-equivalent yield before stacking against corporates or Treasuries.
- Prefer yield to worst when a bond is callable and the screener offers it.
- Treat YTM as a starting rank-order, then read the prospectus/issuer details and your tax lot consequences.
- Inside IRAs, tax accretion/amortization matters less; outside, pair YTM with the premium/discount guides above.
Checklist
- Do not confuse coupon rate with YTM.
- Confirm hold-to-maturity and reinvestment assumptions fit how you invest.
- Check call features and yield-to-worst on callable bonds.
- Match tax treatment before comparing YTMs across munis and taxables.
- Layer duration, convexity, and credit risk on top of the yield number.
- Use broker YTM as a quote convention—verify the day-count and compounding footnote when amounts are large.
