In mathematics we had exponents which were the power to a given any base number, in excel we have a similar inbuilt function known as POWER function which is used to calculate the power of a given number or base, to use this function we can use the keyword =POWER( in a cell and provide two arguments one as number and another as power.

**Syntax**: =POWER (number, power)

The POWER function syntax has the following arguments:

**Number**Required. The base number. It can be any real number.-
**Power**Required. The exponent to which the base number is raised.

**Example**: Let’s look at some Excel POWER function examples and explore how to use the POWER function as a worksheet function in Microsoft Excel:

**Syntax**: =POWER(A2,B2)

**Result**:

Based on the Excel spreadsheet above, the following POWER examples would return:

**Syntax**:=POWER(A3,B3)

**Result**: 123

**Syntax**:=POWER(A4,B4)

**Result**: 3

**Syntax**:=POWER(A5,B5)

**Result**: 5

**Syntax**:=POWER(A6,B6)

**Result**: 9.882117688

**Syntax**:=POWER(A7,B7)

**Result**: 2

**Syntax**:=POWER(A8,B8)

**Result**: 9

**Syntax**: =POWER(A9,B9)

**Result**: 4096

**Syntax**: =POWER(A10,B10)

**Result**: 3125

**Syntax**: =POWER(A11,B11)

**Result**: 2401

**Syntax**: =POWER(A12,B12)

**Result**: 256

**Example 2: **For different mathematical calculations, we can use POWER function in Excel.

Suppose, we have to find out the compound interest for which the formula is

Amount = Principal (1 + r/n)^{nt}

- Where r is the rate of interest, n is number of times interest is compounded per year and t is the time
- If an amount of $10000 is deposited into an account (saving) at an interest rate of 7% annually, compounded monthly, the value of the investment after 6 years can be calculated using the above compound interest formula.
- Where Principal = $4000, rate = 7/100 that is 0.07, n =12 (compounded monthly), time =6 years

Using the compound interest formula and implementing it into excel formula using the POWER function in Excel:

**Syntax**: =B2*(POWER((1+(B3/B5)),(B4*B5)))

**Result**:

The investment balance after 6 years is $15.201,05504

**Note**:

- For a better understanding, we can represent the power function in this way. POWER(X, Y) or POWER(X^Y) both are same only.
- The POWER function is applied only for numerical values. Anything other than numerical values, it will throw the error as
**#VALUE!**If any one of the parameters contains non-numerical values, we will get the error. Below image shows the example of the error.
