Yield to call (YTC) is the annualized rate of return an investor will earn if a callable bond is held only until its first (or next) call date and the issuer repurchases the bond at the stated call price. It answers the question: “If the issuer calls the bond on the call date, what is my effective yield from purchase to that date?”
Why YTC matters
– Callable bonds give issuers the right to repay principal early (usually at a premium). That option can reduce the investor’s realized return if interest rates decline and the issuer refinances at lower rates.
– YTC provides a more realistic estimate of expected return for a callable bond than yield to maturity (YTM) because issuers commonly call bonds when it benefits them (e.g., when rates fall).
– Comparing YTC, YTM, and yield-to-worst (YTW) helps estimate downside scenarios and reinvestment risk.
Key terms
– Call date (or dates): the date(s) when the issuer may redeem the bond early.
– Call price (CP): the price the issuer pays on the call date (often par plus a small premium).
– Coupon (C): the annual cash interest paid by the bond.
– Call protection: an initial period during which the bond cannot be called.
– Yield-to-worst (YTW): the lowest yield an investor would receive, considering all possible call/maturity outcomes (often the minimum of YTC and YTM).
How YTC is defined (conceptually)
YTC is the compound interest rate (annualized) that equates:
Present value of all coupon payments through the call date plus the discounted call price = current market price.
The formula (semiannual coupons)
P = (C / 2) × { [1 − (1 + YTC/2)^(−2t)] / (YTC/2) } + CP / (1 + YTC/2)^(2t)
Where:
– P = current market price of the bond
– C = annual coupon (dollar)
– CP = call price (dollar)
– t = years until the call date
– YTC = annual yield-to-call (decimal)
Because YTC appears inside an exponent and a denominator, the equation cannot be solved algebraically; an iterative (numerical) method is required.
Practical methods to compute YTC
1. Financial calculator (recommended)
• Set N = total number of coupon periods until call (for semiannual coupon bonds, N = 2 × t).
• Set PMT = coupon per period (C / 2).
• Set PV = −P (negative because it’s the investor’s cash outflow to buy the bond).
• Set FV = CP (call price received at call date).
• Compute I/Y (period rate), then annualize (multiply by 2 for semiannual).
2. Spreadsheet (Excel / Google Sheets)
• Use the RATE function for period rate then annualize. Example for semiannual coupons:
=RATE(2*t, C/2, -P, CP) * 2
• Ensure sign convention: PV as negative if purchase is an outflow.
3. IRR approach (explicit cash flows)
• Build cash-flow series: at purchase date, −P; each coupon date until call, +C/2; at call date, +CP.
• Use IRR(cashflows) and annualize if IRR returns period rate (for semiannual, multiply IRR by 2).
4. Manual trial-and-error
• Substitute candidate YTC values into the formula and adjust until computed PV ≈ market price. This is slow and error-prone—use only to understand the mechanics.
Worked example (from source)
– Face value: $1,000 (not directly needed unless call price specified relative to par)
– Coupon: 10% annual → C = $100
– Current market price: P = $1,175
– Call price: CP = $1,100
– Years until call: t = 5
– Semiannual coupons → nper = 2 × 5 = 10; coupon per period = $50
Set up in Excel:
=RATE(10, 50, -1175, 1100)*2
Result: YTC ≈ 7.43% (annual nominal yield, compounded semiannually).
Interpreting this result
– If the issuer calls the bond in 5 years at $1,100, the investor realizes a 7.43% annualized return from the purchase date to the call date (assuming coupons are reinvested at that rate).
– If conditions cause the bond not to be called, the investor might instead realize the yield to maturity (which could be higher or lower).
Practical steps for investors when evaluating callable bonds
1. Identify call features up front
• Read the bond’s prospectus or official statement to find call dates, call prices, and any call schedule or step-down call price. Note any call protection period.
2. Calculate YTC and YTM (and YTW)
• Compute YTC for the next likely call date(s) and the YTM to maturity.
• Determine the yield-to-worst (the lower of these yields) to understand the downside yield scenario.
3. Consider the issuer’s incentive to call
• Issuers typically call when market rates are lower than the bond’s coupon (to refinance cheaper). If rates likely fall, YTC is the more realistic outcome. If rates likely rise, issuer is less likely to call and YTM may be more relevant.
4. Assess reinvestment risk
• If the bond is called, you’ll get principal back earlier and may need to reinvest at lower rates. Factor that into your cash-flow planning and return expectations.
5. Compare compensation for call risk
• Callable bonds generally offer higher coupons to compensate investors for call risk. Compare yield spreads vs. non-callable alternatives with similar credit and duration.
6. Use diversification and laddering
• To mitigate call/reinvestment risk, consider ladders (bonds with staggered maturities), or blend callable with non-callable bonds.
7. Consider alternative protections
• Look for bonds with longer call protection, step-down call premiums, or call schedules that make early calling less attractive to issuers.
8. Use yield-to-worst as a conservative planning metric
• Price portfolios and cash-flow plans using YTW to avoid overestimating returns.
Common investor questions
– Are callable bonds better than non-callable bonds?
They can be better for investors who demand higher yield and accept call risk; non-callable bonds are preferable for investors who want predictable cash flows and guaranteed exposure until maturity. Callable bonds typically pay higher coupons to compensate for issuer’s call option.
• Are most bonds callable?
Many corporate and municipal bonds are callable. Most U.S. Treasury notes and bonds are non-callable. Always check the bond’s terms.
• What happens to callable bonds when interest rates rise?
Issuers are less likely to call when rates rise, so callable bonds are less likely to be redeemed early; investors benefit from higher coupon payments but bond prices typically fall with rising rates (interest-rate risk).
Risks and limitations to remember
– Call risk: issuer can redeem early, limiting upside and causing reinvestment into possibly lower rates.
– Reinvestment risk: coupons and returned principal could be reinvested at lower rates.
– Model risk: YTC assumes the bond will be called at the stated call date; issuers could call at a later date or not at all, and call provisions can be complex (multiple call dates, sinking funds).
– Credit risk and liquidity: callable bonds still carry issuer credit risk; secondary market liquidity can affect execution of trading strategies.
Bottom line — how to use YTC
– Compute YTC whenever evaluating a callable bond and compare it to YTM and YTW to see realistic return scenarios.
– Use calculators, spreadsheets, or financial calculators to solve YTC rather than hand-iterating.
– Combine YTC analysis with issuer incentives, interest-rate outlook, and your reinvestment needs to make a well-informed decision.
