Excel POWER function

Summary

The Excel POWER function computes the result of a number raised to a given power. It’s an essential function in mathematical calculations, especially where exponentiation is required, such as in compound interest calculations, exponential growth models, or scientific formulas.
Syntax
				
					=POWER(number, power)
				
			
  • number: The base number
  • power: The exponent to which the base number is raised
Return value
The result of raising number to the power.

How to use

Use POWER by inputting the base number and the exponent. The function will calculate the base number raised to the exponent.

Examples

Simple POWER
Calculating Exponentiation: Finding the result of a number raised to a specific power:
				
					=POWER(5, 2)
				
			
This formula calculates 5 raised to the power of 2, resulting in 25.
POWER in Financial Modeling
Compound Interest Calculation: Using POWER to calculate compound interest:
				
					=Principal * POWER(1 + Rate, Periods)
				
			
This formula calculates the future value of an investment based on the principal amount, interest rate, and number of periods.
MOD for Cyclical Patterns
Creating Cyclical Sequences: Using MOD to generate repeating patterns:
				
					=POWER(10, -3)
				
			
Calculates 10 raised to the power of -3, resulting in 0.001.
POWER in Engineering
Engineering Stress-Strain Calculations: Utilizing POWER in engineering formulas:
				
					=Stress * POWER(Strain, 2)
				
			
This might represent a calculation where stress is proportional to the square of strain.

Additional Notes

  • POWER is a versatile function used in a wide array of mathematical, scientific, and financial calculations.
  • It’s a more intuitive alternative to using the caret (^) operator for exponentiation in Excel.
