Understanding basic Excel formulas


Excel is a powerful tool for performing calculations and data analysis. Understanding how to use basic formulas is essential for anyone working with Excel. Here, we will cover some of the most commonly used formulas and arithmetic operators in Excel.

A. Sum, Average, Min, Max


  • SUM: The SUM function is used to add up a range of cells. For example, =SUM(A1:A10) will add the values in cells A1 through A10.
  • AVERAGE: The AVERAGE function calculates the average of a range of cells. For example, =AVERAGE(B1:B5) will give you the average of the values in cells B1 through B5.
  • MIN: The MIN function returns the smallest number in a range. For example, =MIN(C1:C8) will give you the smallest value in cells C1 through C8.
  • MAX: The MAX function returns the largest number in a range. For example, =MAX(D1:D6) will give you the largest value in cells D1 through D6.

B. Using basic arithmetic operators (+, -, *, /)


  • Addition (+): The plus sign is used for addition in Excel. For example, =A1+B1 will add the values in cells A1 and B1.
  • Subtraction (-): The minus sign is used for subtraction. For example, =C1-D1 will subtract the value of cell D1 from the value of cell C1.
  • Multiplication (*): The asterisk symbol is used for multiplication. For example, =E1*F1 will multiply the values in cells E1 and F1.
  • Division (/): The forward slash is used for division. For example, =G1/H1 will divide the value in cell G1 by the value in cell H1.


Working with cell references


When working with calculations in Excel, it's important to understand how cell references work. By using cell references, you can create formulas that automatically update when you change the data in your worksheet. There are three types of cell references to be aware of: relative, absolute, and mixed references.

A. Relative references

Relative references are the most commonly used type of cell reference in Excel. When you create a formula using relative references, Excel will adjust the reference based on the position of the formula. For example, if you have a formula in cell C1 that references cell A1, when you copy the formula to cell C2, it will automatically update to reference cell A2.

B. Absolute references

Absolute references, denoted by the use of dollar signs ($), do not change when copied or moved. This means that if you have a formula in cell C1 that references cell $A$1, when you copy the formula to cell C2, it will still reference cell $A$1. Absolute references are useful when you want a reference to remain constant, such as when working with constants or fixed values.

C. Mixed references

Mixed references are a combination of relative and absolute references. You can have either an absolute column and relative row reference (e.g. $A1), or a relative column and absolute row reference (e.g. A$1). When copied or moved, the relative or absolute aspect of the reference will adjust accordingly. Mixed references are especially useful when working with data tables or when you need to lock only a part of the reference.


Advanced functions for complex calculations


When it comes to performing complex calculations in Excel, there are several advanced functions that can help you streamline your workflow and save time. In this tutorial, we will explore some of the most useful functions for complex calculations.

IF function


The IF function in Excel allows you to perform a logical test and return one value if the test is true, and another value if the test is false. This can be extremely useful for creating dynamic spreadsheets that respond to changing conditions.

VLOOKUP function


The VLOOKUP function is a powerful tool for looking up and retrieving data from a table. It allows you to search for a value in the left-most column of a table and return a value in the same row from a specified column.

SUMIF and COUNTIF functions


The SUMIF and COUNTIF functions are useful for adding or counting cells that meet a specified condition. For example, you can use the SUMIF function to sum the values in a range that meet certain criteria, or the COUNTIF function to count the number of cells in a range that meet a specific condition.

Nested functions


In Excel, you can nest one function inside another to create more complex calculations. This can be particularly useful when you need to perform multiple calculations within a single formula. By nesting functions, you can create sophisticated and dynamic spreadsheets that can handle a wide range of scenarios.


Using built-in Excel tools for calculations


Excel offers a variety of built-in tools that can help you perform complex calculations quickly and accurately. Let’s take a look at three powerful tools for calculations in Excel: Goal Seek, Data Tables, and Scenario Manager.

A. Goal Seek

Goal Seek is a handy tool that allows you to find the input value needed to achieve a specific goal. This can be particularly useful when you have a target outcome in mind and want to determine the input required to reach that outcome.

- How to use Goal Seek:


  • Select the cell containing the formula you want to calculate.
  • Go to the Data tab, click on What-If Analysis, and then select Goal Seek.
  • Enter the target value you want to achieve, the cell containing the input value you want to change, and the cell that contains the formula you want to calculate.
  • Click OK to let Excel determine the input value needed to reach the specified goal.

B. Data Tables

Data Tables are a powerful way to perform multiple calculations at once by varying one or two input values. This can be useful for performing sensitivity analysis or creating different scenarios based on changing input variables.

- How to use Data Tables:


  • Create a table with the input values and formulas you want to calculate.
  • Select the range of cells you want to use as the input values.
  • Go to the Data tab, click on What-If Analysis, and then select Data Table.
  • Specify the input cell references and the row or column input cell, and Excel will calculate and display the results in the table.

C. Scenario Manager

Scenario Manager allows you to create and compare different scenarios based on changing input values. This can be useful for evaluating the impact of different variables on a given outcome.

- How to use Scenario Manager:


  • Go to the Data tab and click on What-If Analysis.
  • Select Scenario Manager and then click on Add to create a new scenario.
  • Enter a name for the scenario and specify the changing cells and values for that scenario.
  • Once you have created multiple scenarios, you can compare and switch between them to see the impact on your calculations.


Tips for efficient calculations in Excel
