5 Simple Formulas To Calculate Age In Google Sheets

Calculating age in Google Sheets can be incredibly useful, whether you’re managing a contact list, tracking birthdays, or performing data analysis. Luckily, there are simple formulas that can help you compute ages based on birthdates. Let's dive into five effective ways to calculate age in Google Sheets, with tips on avoiding common mistakes and troubleshooting any issues you may encounter.

The Basics of Age Calculation

To calculate age in Google Sheets, you typically need two key pieces of information: the person's birthdate and the current date. Using formulas, you can derive the age in years, months, or even days. Below are five straightforward formulas, each suited for different situations.

1. Calculate Age in Years

To find the age in complete years, you can use the DATEDIF function, which stands for "date difference." This formula subtracts the birthdate from the current date and gives the total years.

=DATEDIF(birthdate, TODAY(), "Y")

Example: If the birthdate is in cell A1, you would write:

=DATEDIF(A1, TODAY(), "Y")

2. Calculate Age in Months

If you're interested in knowing the person's age in months, you can adjust the DATEDIF formula slightly. Instead of "Y," you'll use "M" to get the number of complete months since the birthdate.

=DATEDIF(birthdate, TODAY(), "M")

Example: In cell A1, if the birthdate is entered, the formula would be:

=DATEDIF(A1, TODAY(), "M")

3. Calculate Age in Days

Sometimes, you might want a more granular view—like age in days. For this, you can continue using DATEDIF with "D" to get the total number of days.

=DATEDIF(birthdate, TODAY(), "D")

Example: Again, if the birthdate is in cell A1, your formula will be:

=DATEDIF(A1, TODAY(), "D")

4. Calculate Age with Years and Months

If you want to know both years and months, you can use the following combination of formulas to return a text string indicating both.

=DATEDIF(birthdate, TODAY(), "Y") & " years, " & DATEDIF(birthdate, TODAY(), "YM") & " months"

Example: With the birthdate in cell A1:

=DATEDIF(A1, TODAY(), "Y") & " years, " & DATEDIF(A1, TODAY(), "YM") & " months"

5. Calculate Age with Exact Days

For a complete and precise age calculation including days, you can build upon the previous formula. This will show the age in years, months, and days.

=DATEDIF(birthdate, TODAY(), "Y") & " years, " & DATEDIF(birthdate, TODAY(), "YM") & " months, " & DATEDIF(birthdate, TODAY(), "MD") & " days"

Example: Entering this with the birthdate in A1:

=DATEDIF(A1, TODAY(), "Y") & " years, " & DATEDIF(A1, TODAY(), "YM") & " months, " & DATEDIF(A1, TODAY(), "MD") & " days"

Common Mistakes to Avoid

• Incorrect Date Format: Ensure that the birthdate is in a recognized date format (like MM/DD/YYYY or DD/MM/YYYY) in Google Sheets. If you see errors or incorrect results, the date might be misformatted.
• Using Current Date: Always use TODAY() as the end date for age calculations to ensure it updates automatically.
• Negative Ages: Be cautious of birthdates that are set in the future; this will yield negative age results.
• Function Limitations: The DATEDIF function can be a bit quirky, as it's not listed in the Google Sheets function list. Ensure you type it correctly or else it may return errors.

Troubleshooting Issues

• Error Messages: If you encounter errors like #VALUE!, double-check that both inputs are valid dates.
• Dynamic Updating: Remember that TODAY() updates every day. If you need a static date, you can input a specific date instead.
• Text Strings: If results appear as text instead of numbers, ensure the cell format is set to “Number” and not “Text.”
