Understanding Yield to Call (YTC)
Yield to call measures the annualized return on a callable bond if the issuer exercises its call option and repurchases the bond at the stated call price before final maturity. For premium bonds trading above par, YTC is often lower than yield to maturity because the investor faces an earlier exit at a price below market value.
Callable bonds give issuers the right to retire debt early, typically when interest rates fall. Before buying a premium callable bond, compare YTC against your required return and against yield to maturity using our yield to maturity calculator.

Exact YTC Formula
The exact yield to call solves for the periodic rate that equates the bond purchase price to the present value of all coupon payments plus call proceeds:
Where is the market price, is the periodic coupon payment, is the call price, and is the number of coupon periods until the call date. Annual YTC equals the periodic rate multiplied by the payment frequency per year.
Approximate YTC Shortcut
A quick estimate uses the standard bond yield approximation adapted for the call price:
Worked Example
Consider a $1,000 par bond with a 6.00% annual coupon (paid semi-annually), trading at $1,050, callable in 5 years at $1,030:
- Periodic coupon: $30.00 (6% of $1,000 divided by 2)
- Total periods to call: 10 semi-annual payments
- Final cash flow at call: $1,060.00 ($30 coupon + $1,030 call price)
- Exact YTC: approximately 4.8% to 5.2% (bisection solves the full cash flow schedule)
Because the bond trades at a premium ($1,050) but can be called at $1,030, the investor faces a capital loss at call that partially offsets coupon income, pulling YTC below the 6.00% coupon rate.
When YTC Matters Most
YTC is most relevant for premium callable bonds where the issuer is likely to call when rates drop. If a bond trades near or below par, yield to worst (the lower of YTC and YTM) may equal YTM. Always evaluate both scenarios before committing capital to callable fixed income.
