Calculating yield to maturity in Excel is a crucial step in evaluating bond investments. The yield to maturity formula is a complex calculation that involves several variables.
To calculate yield to maturity, you need to input the following values: the bond's face value, the annual coupon rate, the number of years until maturity, and the current market price.
The yield to maturity formula in Excel is YTM = (FV x (1 + r)^n) / PV, where FV is the face value, r is the annual coupon rate, n is the number of years, and PV is the present value or current market price.
The formula can be simplified by using Excel's built-in functions, such as the YIELD function, which returns the yield to maturity for a bond.

Yield to Maturity Formula in Excel
The Yield to Maturity formula in Excel is a powerful tool for calculating the return on investment for a bond. It's calculated using the RATE function, which helps find the interest rate for an annuity.
To use the RATE function, you'll need to input the total number of payment periods, payment made each period, present value (or bond price), future value (or bond face value), and type of payment. The syntax for the RATE function is: nper: Total number of payment periods (years to maturity multiplied by coupons per year).pmt: Payment made each period (coupon payment).pv: Present value, or the bond’s price (enter as a negative number).fv: Future value, or the bond’s face value (optional here but should be included).type: When payments are due (0 for end of period, which is typical for bonds).
You can also use the YIELD function, which extracts every single value from the dataset as arguments and gives the YTM values in the selected cells, using the formula: =YIELD(C6,C7,C5,C10,C4,C8).

What Is Yield to Maturity
Yield to Maturity (YTM) is essentially the internal rate of return (IRR) for a bond, making the present value of all future cash flows (coupons and principal) equal to the bond's current price.
Think of YTM as the average annual return you'd earn if you held the bond until it matures. It assumes that all coupon payments are reinvested at the same rate as the YTM.
YTM gives investors a way to compare bonds with different maturities and coupon rates on an equal footing, like having a common language for bond returns.
To calculate YTM, you need to know the bond's current market price, the coupon interest rate, the face value, and the number of years remaining until maturity.
Here's a breakdown of the key components:
- Current market price
- Coupon interest rate
- Face value
- Number of years remaining until maturity
With this information, you're ready to move on to using Excel to calculate YTM.
The YTM you calculate is the bond's annual return, assuming you hold it to maturity and all coupon payments are reinvested at the same rate. It's a comprehensive measure because it considers the bond's current price, coupon payments, and maturity value.

Understanding YTM Calculation
The YTM calculation is a comprehensive measure that considers a bond's current price, coupon payments, and maturity value. It's the bond's annual return, assuming you hold it to maturity and all coupon payments are reinvested at the same rate.
The YTM calculation is particularly useful when comparing bonds. If you're weighing two bonds with different coupon rates and prices, YTM helps you see which offers a better return.
A hypothetical bond with a face value of $1,000, a coupon rate of 4%, a market price of $920, and 15 years to maturity, has a YTM of 4.8% using the RATE function. This means, if you buy the bond at $920 and hold it to maturity, you'll effectively earn an average return of 4.8% per year.
Here's a comparison of two bonds:
To calculate the YTM for Bond B, you would use the RATE function, adjusting the variables to match the bond's characteristics.

Calculating Yield in Excel
The RATE function is a handy tool for calculating Yield to Maturity (YTM) in Excel. It helps find the interest rate for an annuity, which is exactly what we need here.
The syntax for the RATE function is: RATE(nper, pmt, pv, [fv], [type], [guess]). Let's break it down:
- nper: Total number of payment periods (years to maturity multiplied by coupons per year).
- pmt: Payment made each period (coupon payment).
- pv: Present value, or the bond's price (enter as a negative number).
- fv: Future value, or the bond's face value (optional here but should be included).
- type: When payments are due (0 for end of period, which is typical for bonds).
- guess: An initial guess for the rate (optional, default is usually fine).
To use the RATE function, input the formula: =RATE(B4*B5, B1*B3/B5, -B2, B1, 0) in cell B6, assuming coupons are paid annually.
The YTM you calculate is the bond's annual return, assuming you hold it to maturity and all coupon payments are reinvested at the same rate.
The YIELD function in Excel can also be used to calculate Yield to Maturity, with the syntax: YIELD(settlement, maturity, rate, pr, redemption, frequency, [basis]).
The YIELDMAT function calculates the annual yield of a security that pays interest at maturity, with the syntax: YIELDMAT(settlement, maturity, issue, rate, pr, [basis]).

Excel Functions for Yield Calculation
Excel has several functions that can help you calculate the yield to maturity (YTM) of a bond. The RATE function is a handy tool for calculating YTM, and its syntax is RATE(nper, pmt, pv, [fv], [type], [guess]). You can use it to find the interest rate for an annuity, which is exactly what you need to calculate YTM.
The RATE function requires you to input the total number of payment periods (nper), the payment made each period (pmt), the present value (pv), the future value (fv), the payment type (type), and an initial guess for the rate (guess). In cell B6, you can input the formula =RATE(B4*B5, B1*B3/B5, -B2, B1, 0) to calculate the YTM.
YTM is a comprehensive measure that considers the bond's current price, coupon payments, and maturity value. If you have a bond with a face value of $1,000, a coupon rate of 4%, a market price of $920, and 15 years to maturity, using the RATE function will give you a YTM of 4.8%. This means that if you buy the bond at $920 and hold it to maturity, you'll effectively earn an average return of 4.8% per year.
The YIELDMAT function in Excel calculates the annual yield of a security that pays interest at maturity. However, most securities pay interest periodically, so the YIELDMAT function is only relevant for securities that pay all the interest at maturity. The syntax of the YIELDMAT function is Settlement, Maturity, Issue, Rate, PR, and Basis.
You can use the RATE function to calculate YTM for bonds that pay interest periodically. For example, you can use the formula =RATE(C8,C7,-C6,C4)*C5 to calculate the YTM. The YIELD function in Excel can also easily calculate Yield to Maturity in Excel of a bond. The syntax of the YIELD function is YIELD(settlement, maturity, issue, rate, pr, redemption, frequency, [basis]).

Here's a list of Excel functions for yield calculation:
- RATE function: RATE(nper, pmt, pv, [fv], [type], [guess])
- YIELDMAT function: Settlement, Maturity, Issue, Rate, PR, and Basis
- YIELD function: YIELD(settlement, maturity, issue, rate, pr, redemption, frequency, [basis])
- Solver tool: can be used to solve for YTM by iterating through possible solutions.
Note: The RATE function assumes that coupons are paid annually, but if your bond pays semi-annual coupons, you should adjust the nper argument accordingly.
Using Excel Solver for Complex Bonds
Excel's Solver tool is like a Swiss Army knife for complex financial calculations. It's a powerful tool for bonds with non-standard payment schedules.
To use Solver, you'll need to set up your cash flows in a column, listing out all coupon payments and the final principal repayment. This will be the foundation for your Solver calculation.
In another cell, calculate the present value of these cash flows using a guessed Yield to Maturity (YTM). This is where Solver will start to work its magic.
To get started, you might need to enable Solver through Excel's Add-ins. Once it's enabled, open Solver and set it to minimize the difference between the calculated present value and the bond's price.
By adjusting the YTM value, Solver will iterate until it finds the rate that equates the present value of cash flows to the bond's market price. This is a game-changer for bonds with complexities that stump the RATE function.

Considerations and Syntax
The YIELD function syntax has six arguments, including settlement, maturity, rate, price, redemption, and frequency. The settlement date is the date after the issue date when the security is traded to the buyer.
The YIELDMAT function has five arguments, including settlement, maturity, issue, rate, and price. The issue date is the security's issue date, expressed as a serial date number.
To use the YIELDMAT function, you need to specify the settlement date, maturity date, issue date, rate, and price. You can omit the basis argument, but if you include it, it must be one of the following: 0 (US NASD 30/360), 1 (Actual/actual), 2 (Actual/360), 3 (Actual/365), or 4 (European 30/360).
You may encounter a #NUM! error if the issuance date is greater than or equal to the settlement date, or if the rate, price, or basis arguments have invalid numbers. You may encounter a #VALUE! error if the issuance, settlement, or maturity dates are not valid Excel dates.
