KeyВ takeaway: The output of any formula or function can be fed directly into another formula or function. The TODAY function is a rareВ Excel functionВ with no required arguments.Nested IF functions are aВ classic example of nesting functions.The current date in images above is FebruaryВ 22, 2019.Here, the original YEARFRAC formula returns 20.4 to the INT function, and the INT function returns a final result of 20.

When we press Enter to confirm, we get current age based on today's date: We can use B1 for start date, then use the TODAY function to supply the end date: The YEARFRAC function will calculate years with a start date and end date: For example, below we have a birthdate in B1 and we wantВ to calculate current age in B2: Many Excel formulas use more than one function, andВ functions can be ' nested' inside each other. When you see the function you want in the list, use the arrow keys to select (or just keep typing).Дў. Excel will list of matching functions based as you type: If you know the name of the function, just start typing.

See below for an example of how to use YEARFRAC to calculate current age based on birthdate. Start date and end date are required arguments, basis is an optional argument. For example, you probably know the SUM function already, which returns the sum of given references: Technically, a formula is anyВ expression that begins with an equals sign (=).ДЄ function, on the other hand, is a formula with a special name and purpose.В In most cases, functions have names that reflect their intended use. They are closely related, but not exactly the same. Working in Excel, you will hear the words 'formula' and 'function' used frequently, sometimes interchangeably.

No matter which option you use, press Enter to confirm changes when done.

Select the cell, press F2, edit directly.

Select the cell, edit in the formula bar.

Note references are color-coded:ДЄll formulas in Excel must begin with an equals sign (=). Instead of typing cell references, you can point and click, as seen below. Tip: you can toggle between relative and absolute syntax with the F4 key.

By storing the value in A1 in one place, and referring to A1 with an absolute reference, the value can be changed at any time and all associated formulas will update instantly. This simple example also shows why it doesn't make sense to hardcode values into a formula. Below the value in A1 has changed from 10 to 12:

Now we can easily change the value in A1, and all three formulas recalculate. Notice the reference to D1 updates when the formula is copied, but the reference to A1 never changes. This means the reference isВ relative to the cell it lives in. The cell references above are called relative references. This means you don't need to enter the same basic formula again and again.В In the screen below, the formula in E1 has been copied to the clipboard with Control + C:Д«elow: formula pasted to cell E2 with Control + V. The beauty of cell references is that they automatically updateВ when a formula is copied to a new location. In this case, you could provide the missing value in B4, or 'catch' the error with the IFERROR function and display a more friendly message (or nothing at all). There are different ways of handling errors. The formula returns a correct result in D2 and D3, but returns a #DIV/0! error in D4, because B4 is empty: Below a formula is used to calculate percent change. All formulas return a resultДЄll formulas in Excel return a result, even when the result is an error. Notice because we are using cell references for A1, A2, and A3, these values can be changed at any time and C1 will still show an accurate result.
