To calculate yield to call on a financial calculator, you must treat the transaction as a bond amortization problem where the future value is the call price, not the par value. The yield to call, or YTC, represents the total return an investor would receive if the bond is redeemed by the issuer at the earliest possible call date. This metric is crucial for evaluating callable bonds because it reveals the worst-case scenario for yield, assuming interest rates decline and the bond is called away early. Unlike the yield to maturity, which assumes the bond lives to its final maturity, the yield to call requires you to input the number of periods until the call date and the call price as the terminal value.
Understanding the Inputs for Yield to Call
Before you begin punching numbers into your device, you need to identify five core variables. The present value is the current clean price of the bond, entered as a negative number because it represents a cash outflow to the investor. The payment amount is the periodic coupon interest, calculated by multiplying the coupon rate by the par value and dividing by the number of payments per year. The future value is the call price, which is typically 100% of the par value plus a small call premium. The number of periods is the total number of coupon payments between the purchase date and the call date, and the interest rate per period is the unknown variable you are solving for.
Adjusting for Payment Frequency
One of the most common mistakes when you calculate yield to call on a financial calculator is failing to adjust the periods and the rate for compounding frequency. If a bond pays interest semi-annually, you must convert the annual rate to a periodic rate by dividing by 2 and multiply the number of years by 2. For example, if you are calculating the YTC for a bond with 15 years until the call date and the bond pays twice a year, the N variable should be 30. Skipping this step will result in a mathematically correct number that is technically wrong in a real-world context, as it ignores the effect of compounding.
Step-by-Step Calculation Process
To calculate yield to call, start by entering the present value into the calculator, followed by the payment amount. Next, input the future value, which is the call price, and then enter the total number of periods until the call date. Once these values are stored in the calculator's memory, you press the compute or interest button to solve for the periodic interest rate. After determining the periodic rate, you multiply it by the number of periods in a year to convert it to an annual nominal yield. Finally, to find the effective annual yield, you must account for compounding by raising the periodic rate plus one to the power of the number of periods per year and subtracting one.
Worked Example for Clarity
Imagine a bond with a par value of $1,000 is purchased for $980 and pays a 5% annual coupon semi-annually. The bond is callable in 5 years at a price of $1,010. To solve, you would enter -980 as PV, 25 as N (5 years times 2), and 1010 as FV. Solving for I/Y gives you the semi-annual rate, which you would then double to get the nominal annual yield to call. This specific scenario usually results in a YTC that is slightly higher than the yield to maturity, illustrating how the call premium impacts the return profile. Following these steps ensures you capture the time value of money accurately.
