Complete Guide: How to Calculate Percentages in Excel 2016

Calculating percentages in Excel 2016 is a fundamental skill that applies to financial analysis, data reporting, academic research, and everyday calculations. This comprehensive guide will walk you through all the methods to calculate percentages in Excel 2016, including practical examples and advanced techniques.

1. Basic Percentage Calculations

The most common percentage calculation determines what percentage one number is of another. The basic formula is:

= (Part / Total) * 100

In Excel 2016, you would implement this as:

  1. Enter your total value in cell A1 (e.g., 300)
  2. Enter your part value in cell B1 (e.g., 75)
  3. In cell C1, enter the formula: =B1/A1
  4. Press Enter to get the decimal result (0.25)
  5. Select cell C1, then click the Percent Style button (%) in the Home tab to format as 25%

Pro Tip: Always format your result as a percentage after calculation. Excel stores percentages as decimal values (0.25 = 25%), so formatting is crucial for proper display.

2. Calculating Percentage Increase/Decrease

To calculate the percentage change between two values (increase or decrease):

= (New Value – Original Value) / Original Value * 100

Example implementation:

  1. Enter original value in A1 (e.g., 200)
  2. Enter new value in B1 (e.g., 250)
  3. In C1, enter: =(B1-A1)/A1
  4. Format as percentage to see 25% increase

3. Adding/Subtracting Percentages

To increase or decrease a value by a specific percentage:

Increase by percentage: =Value*(1+Percentage)

Decrease by percentage: =Value*(1-Percentage)

Example (increase 100 by 20%):

=100*(1+20%)

4. Percentage of Total (Common for Budgets)

When working with tables where you need each item’s percentage of the total:

  1. Enter your values in column A (A1:A5)
  2. Calculate the total in A6 with =SUM(A1:A5)
  3. In B1, enter =A1/$A$6 and copy down
  4. Format column B as percentages

The $A$6 creates an absolute reference so the formula always divides by the total when copied to other cells.

5. Advanced Percentage Techniques

Conditional Percentage Formatting

Excel 2016 allows you to apply formatting based on percentage thresholds:

  1. Select your percentage cells
  2. Go to Home > Conditional Formatting > Color Scales
  3. Choose a 2-color or 3-color scale to visually represent your percentages

Percentage Rank

To find what percentile a value falls into:

=PERCENTRANK.INC(Range, Value, [Significance])

Example: =PERCENTRANK.INC(A1:A10, A5) shows what percentile A5 falls in within the range A1:A10.

6. Common Percentage Mistakes to Avoid

  • Forgetting to format as percentage: Cells will show decimal values (0.25 instead of 25%)
  • Incorrect cell references: Using relative references when you need absolute ($A$1)
  • Dividing in wrong order: =A1/B1 gives different result than =B1/A1
  • Not accounting for zeros: Division by zero errors can crash your formulas
  • Assuming percentages add to 100%: Rounded percentages may not sum exactly to 100%

7. Real-World Percentage Applications in Excel 2016

Business Scenario Excel Formula Example Typical Use Case
Sales Growth = (New_Sales – Old_Sales) / Old_Sales Quarterly sales reports showing growth rates
Profit Margins = (Revenue – Cost) / Revenue Financial statements analyzing profitability
Survey Results = COUNTIF(Range, “Yes”) / COUNTA(Range) Calculating percentage of “Yes” responses
Project Completion = Completed_Tasks / Total_Tasks Gantt charts and project management
Discount Calculations = Original_Price * (1 – Discount%) Retail pricing and promotions

8. Excel 2016 Percentage Functions Reference

Function Syntax Purpose Example
PERCENTAGE =Percentage(Part, Total) Calculates what percentage Part is of Total =PERCENTAGE(75, 300) returns 25%
PERCENTRANK.INC =PERCENTRANK.INC(Array, X, [Significance]) Returns the rank of a value as a percentage of the data set =PERCENTRANK.INC(A1:A10, A5) returns 0.6 (60th percentile)
PERCENTILE.INC =PERCENTILE.INC(Array, K) Returns the k-th percentile value in a range =PERCENTILE.INC(A1:A10, 0.25) returns 25th percentile value
PERCENTILE.EXC =PERCENTILE.EXC(Array, K) Returns the k-th percentile excluding 0 and 1 =PERCENTILE.EXC(A1:A10, 0.5) returns median excluding min/max

9. Keyboard Shortcuts for Percentage Work

  • Format as Percentage: Select cells, then press Ctrl+Shift+%
  • Increase Decimal: Alt+H+0 (increases decimal places)
  • Decrease Decimal: Alt+H+9 (decreases decimal places)
  • Quick Sum: Alt+= (auto-sum selected cells)
  • Copy Formula Down: Double-click the fill handle (small square at bottom-right of selected cell)

10. Troubleshooting Percentage Problems

Problem: My percentage shows as 0% when I know it should be higher

Solution: Check that you’re dividing in the correct order (Part/Total, not Total/Part). Also verify your cells are formatted as percentages.

Problem: I’m getting #DIV/0! errors

Solution: Your denominator (total value) is zero or blank. Use IFERROR: =IFERROR(Part/Total, 0)

Problem: My percentages don’t add up to 100%

Solution: This is often due to rounding. Try increasing decimal places or use the ROUND function: =ROUND(Part/Total, 4)

12. Best Practices for Working with Percentages

  1. Always label your data: Include clear headers for your percentage columns
  2. Use consistent formatting: Apply the same percentage format to all related cells
  3. Document your formulas: Add comments (Right-click > Insert Comment) to explain complex percentage calculations
  4. Validate your results: Cross-check with manual calculations for important data
  5. Consider significant figures: Standardize on 1-2 decimal places for percentages unless precision is critical
  6. Use named ranges: For complex workbooks, name your percentage ranges (Formulas > Define Name)
  7. Protect your formulas: Lock cells with important percentage calculations (Review > Protect Sheet)

Expert Insight: When working with large datasets, consider using Excel Tables (Ctrl+T) for your percentage calculations. This automatically extends formulas to new rows and provides better data management.

13. Automating Percentage Calculations

For repetitive percentage tasks, consider creating custom functions with VBA:

  1. Press Alt+F11 to open the VBA editor
  2. Insert a new module (Insert > Module)
  3. Paste this custom percentage function: 
    Function CustomPercent(Part As Double, Total As Double, Optional Decimals As Integer = 2) As Double
    If Total = 0 Then
        CustomPercent = 0
    Else
        CustomPercent = WorksheetFunction.Round(Part / Total, Decimals)
    End If
End Function
  4. Now use =CustomPercent(75, 300) in your worksheet

14. Percentage Calculations in Pivot Tables

Pivot Tables offer powerful percentage analysis:

  1. Create your Pivot Table (Insert > PivotTable)
  2. Add your data fields to Rows and Values areas
  3. Click the dropdown on any value field and select “Value Field Settings”
  4. Choose “Show Values As” tab and select:
    • % of Grand Total – Each value as percentage of overall total
    • % of Column Total – Each value as percentage of its column
    • % of Row Total – Each value as percentage of its row

15. Visualizing Percentages with Charts

Excel 2016 offers several chart types perfect for percentage data:

  • Pie Charts: Best for showing parts of a whole (limit to 5-6 categories)
  • Stacked Column/Bar Charts: Great for comparing percentages across groups
  • 100% Stacked Charts: Shows each stack as 100%, ideal for composition analysis
  • Doughnut Charts: Similar to pie charts but can show multiple data series

To create a percentage chart:

  1. Select your data (including percentage column)
  2. Insert > Recommended Charts
  3. Choose a pie or stacked chart type
  4. Add data labels showing percentages (Chart Design > Add Chart Element > Data Labels)
