II. Basic concepts and definitions
Before we dive into the step-by-step guide, it’s important to understand some basic concepts and definitions related to percentage increase and Excel functions.
A. Explanation of percentage increase
Percentage increase is a measure of the difference between two numbers, expressed as a percentage of the original number. For example, if you have a starting value of 50 and an ending value of 75, the percentage increase would be (75-50)/50 x 100 = 50%. This means that the ending value is 50% greater than the starting value.
B. Definition of relative and absolute references
Excel uses two types of references when calculating formulas: relative references and absolute references. Relative references are cell references that can change when you copy or fill a formula to other cells. Absolute references, on the other hand, remain constant regardless of where the formula is copied or filled. You can make a reference absolute by adding a “$” sign before the column letter or row number. For example, $A$1 is an absolute reference to cell A1.
C. Basic Excel functions for calculating percentage increase
Excel offers several functions for calculating percentage increase, including:
- The “=” sign, which indicates the start of a formula
- The “-” sign, which indicates subtraction
- The “/” sign, which indicates division
- The “*” sign, which indicates multiplication
- The “%” sign, which indicates percentage
- The “ROUND” function, which rounds a number to a specified number of decimal places
III. Step-by-step guide
Now that we understand the basic concepts and functions, let’s walk through an example of how to calculate percentage increase in Excel.
A. Sample data and screenshots

C. Tips and tricks for streamlining the process
To streamline the process of calculating percentage increase in Excel, here are some additional tips and tricks:
- Use the “AutoFill” feature to copy formulas down a column without having to drag the formula. Simply select the cell with the formula, hover over the bottom right corner until the cursor turns into a “+” sign, and click and drag down the column.
- Use the “ROUND” function to round percentages to a specified number of decimal places. For example, =ROUND(B2/A2-1,2) would round the percentage increase to two decimal places.
- Use conditional formatting to highlight cells with certain characteristics, such as positive or negative percentage changes. This can help make trends and patterns in the data more visible.
