Yield to Call Calculator
Many corporate and municipal bonds include a call provision allowing the issuer to redeem the bond early at a preset call price. When market interest rates fall, issuers are incentivised to call their high-coupon bonds and refinance at lower rates, just as a homeowner refinances a mortgage. For investors holding callable bonds, yield to maturity may not reflect the true expected return because the bond may be redeemed before maturity. Yield to call (YTC) measures the return assuming the bond is called on the first call date. It is calculated using the same present value method as YTM but substitutes the call price for the face value and the years to call for the years to maturity. This calculator uses Newton-Raphson iteration to solve for the precise YTC.
Yield to call formula
Solve r such that: Price = sum(C/(1+r)^t) + Call Price/(1+r)^n
where t = 1 to n = Years to Call x freq
C = (Face x Coupon Rate) / freq
YTC (annualised) = r x freq
The YTC formula is identical to the YTM formula except the terminal cash flow is the call price (not face value) and n is the number of periods to the call date.
Callable bond considerations
- Premium bonds (priced above par) are most at risk of being called when rates fall.
- Always compare YTC with YTM. The lower figure (yield to worst) is the conservative return estimate.
- Municipal bonds frequently include call features, making YTC analysis essential.
- Call premiums (call price above face value) partially compensate investors for call risk.
- Make-whole call provisions adjust the call price to market yield, effectively eliminating the call incentive for issuers in rising rate environments.
Yield to call: frequently asked questions
What is a callable bond?
A callable bond gives the issuer the right to redeem the bond before maturity at a specified call price, usually on or after a defined call date. Issuers typically exercise this option when market rates fall below the coupon rate, allowing them to refinance at a lower cost.
Why is yield to call important for investors?
If a bond is likely to be called (especially premium bonds where the issuer benefits from calling), YTM overstates the expected return because it assumes you hold to maturity. YTC gives a more realistic return estimate for the period until the likely call date.
What is the call price?
The call price is the amount the issuer pays to redeem the bond at the call date. It is often face value ($1,000) or slightly above (e.g., $1,030) to compensate investors for the call risk. Always check the bond's prospectus for the specific call schedule.
What is yield to worst (YTW)?
Yield to worst is the lowest of all possible yields: yield to maturity, yield to each call date, and yield to put. It represents the minimum return you can earn if the issuer or bondholder exercises every available option against your interest. Conservative investors focus on YTW.
When is YTC lower than YTM?
For premium bonds (priced above face value), YTC is typically lower than YTM. The issuer will redeem at the call price (often at or near face value), resulting in a capital loss for the premium buyer. The coupon stream to the call date does not fully compensate for this loss, reducing overall yield.
