Learn Excel Formulas and Functions

Excel offers over 300 functions and formulas to help you get more out of your spreadsheets. This page contains a summary of the functions that are covered by lessons on this site. It's being added to all the time, so check back often!

VLOOKUP allows you to look for a specified value in a column of data inside a table, and then fetch a value from another column in the same row. An example might be where you need to find the sales for a specific salesperson from within a monthly sales report. In this lesson you'll learn how to use VLOOKUP in your spreadsheets by walking you through several simple examples. The lesson will also highlight some shortcomings of VLOOKUP, plus a solution to those shortcomings.

The IF() function in Excel allows you to evaluate a situation which has two possible outcomes (e.g. sales are greater than $1000) and calculate a different value for each outcome. However, sometimes you need to work with situations where there are more than two possible outcomes. That's where multiple, or nested, IF functions come in handy. In this tutorial we'll cover how to use nested IF functions to calculate sales commission for a team of sales people, given a range of different commission rates.

The SUM function in Excel allows you to add up the values in a range of cells. However, sometimes you only want to add up the cells that meet certain criteria. That's where the SUMIF function comes in handy, along with the more capable SUMIFS function.

It can sometimes be useful to know the address of a cell in a worksheet, so you can use that address in a formula. In this lesson, we'll look at how to use the ADDRESS function to find out the address of a cell. We'll then use the ADDRESS function in an example to demonstrate how useful it can be.

If you have a column of numbers and you want to calculate a running total of the numbers alongside, you can use the SUM() formula combined with a clever use of absolute and relative references.

The SUMIFS function in Excel allows you to sum the values in a range of cells that meet multiple conditions, or criteria. For example, you might use the SUMIFS function in a sales spreadsheet to to add up the value of sales of a specific product by a given sales person (e.g. the value of all sales of a microwave oven made by John). This lesson explains how to use SUMIFS.

If you're using Excel to calculate dates, it is useful to know how to add (or subtract) a certain number of working or business days to a date. This lesson introduces the WORKDAY() function and shows you how to use it.

If you're using the Autofilter feature, you're probably wondering how to perform calculations on only those values that are being displayed by the filter. The SUBTOTAL() function is the answer.
