# How to Calculate Age in Excel

Excel is more than numbers and charts. You can use it to calculate the age from dates, whether it’s for personal use, work projects, or data analysis. In this guide, I’ll show you how to calculate age in Excel without overcomplicating things.

**Why You Should Learn to Calculate Age in Excel**

Excel accelerates age calculation, surpassing manual processing speed. You can use it to track birthdates, policy ages, and work anniversaries. Also, this skill makes you more attractive to employers. This is especially true for accounting, finance, and data analysis roles.

**Steps to Calculate Age in Excel**

### 1. Open your Excel file.

Start by opening Excel. Either create a new file or open an existing one. If you’re dealing with many files, double-click the one you need.

### 2. Format your dates.

Enter the relevant dates in the correct format, such as DD/MM/YYYY. For example, enter someone’s birthdate in one cell and today’s date in the adjacent cell. You can enter as many dates as you want for as many calculations.

### 3. Use the YEARFRAC formula.

Once your dates are set, use the YEARFRAC function to calculate the years between the start and end dates. This function returns the fractional difference between two dates.

Here’s the formula:

`=`

INT`(`

YEARFRAC`(B2,`

TODAY`(),`

1`))`

In this formula:

`B2`

is the birthdate.`TODAY()`

calculates the current date.`1`

refers to a full year (365 days).

Hit **Enter**, and Excel will display the person’s age in years.

### 4. Use the DATEDIF formula for more details.

Another function you can use is DATEDIF, which returns the difference in years, months, or days. Here’s the formula:

**=DATEDIF(A2,B2,”Y”)**

This shows the age difference in years. You can change the “Y” to:

- “M” for months,
- “D” for days,
- “YM” for months without counting years.
- “MD” for days without counting months or years.
- “YD” for days without counting years.

Hit **Enter**, and Excel will show the age difference based on your selection.

## Common Functions for Age Calculation

Here are some key Excel functions you can use to calculate age:

### 1. DATEDIF Function

Users use the DATEDIF function to find the time between two dates in years, months, or days. Use it when you want detailed age calculations.

### 2. YEARFRAC function

The YEARFRAC function gives a fraction for two dates. Use the INT function to convert it to a whole number.

**=INT(YEARFRAC(B2,TODAY(),1))**

### 3. ROUNDDOWN Function

Use the ROUNDDOWN function to drop decimal places from your result. This is useful when you want the exact year without fractions.

**=ROUNDDOWN((B1-A1)/365.25, 0)**

Function | Purpose | Example |

`DATEDIF` | Calculate the time difference | `=DATEDIF(A2,B2,"Y")` |

`YEARFRAC` | Get the fractional year difference | `=YEARFRAC(A2,B2,1)` |

`ROUNDDOWN` | Round down decimals | `=ROUNDDOWN((B2-A2)/365.25,0)` |

`INT` | Convert fractional years to whole | `=INT(YEARFRAC(A2,B2,1))` |

**Real-Life Scenarios for Calculating Age in Excel**

### Planning Birthdays

Determine someone’s age on their next birthday using Excel’s calculation feature. Enter the birthdate in one cell and today’s date in another, then use the formulas shared above.

### Tracking Employment Length

To track a person’s employment duration, enter the start and current dates. Excel will then calculate the years, months, or days worked.

### Managing Insurance Policies

You can also use these functions to track an insurance policy’s end and enter the start and today’s date. This ensures your policies stay up to date.

**Wrapping Up**

Excel makes it easy to calculate age from dates. Use simple formulas like YEARFRAC and DATEDIF. These methods save you time, reduce manual calculations, and help you focus on other tasks. Now that you know the basics, you can use these formulas in your work and personal projects.

## Frequently Asked Questions (FAQs)

**1. What is the easiest way to calculate age in Excel?**

The easiest way to calculate age in Excel is using the **YEARFRAC** function. This formula calculates the number of years between two dates:

**=INT(YEARFRAC(B2, TODAY(), 1))**

Here, B2 represents the birthdate, and `TODAY()` calculates the current date.

### 2. Can I calculate the age in months or days?

Yes, you can use the **DATEDIF** function to calculate the age in months or days. For example:

To calculate age in months:

**=DATEDIF(A2, B2, “M”)**

To calculate age in days:

**=DATEDIF(A2, B2, “D”)**

### 3. What’s the difference between the YEARFRAC and DATEDIF functions?

**YEARFRAC** returns the fractional number of years between two dates. You can round it down to get a whole number.

**DATEDIF** gives the difference in years, months, or days, depending on the format you choose.

### 4. Can I calculate the age without showing decimals?

Yes, you can use the **INT** or **ROUNDDOWN** function to remove decimals. For example:

**=ROUNDDOWN((B1-A1)/365.25, 0)**

This formula rounds down the result to the nearest whole number.

### 5. How do I calculate the ages of many people at once?

Copy the formula to other cells to compute the ages of many individuals. Excel recalculates cell references and determines each person’s age from birth.

### 6. Can I calculate future or past ages with Excel?

You can replace the `TODAY()` function with any specific date. For example, to calculate the age on a future or past date, you can replace `TODAY()` with that specific date:

**=INT(YEARFRAC(B2, “01/01/2025”, 1))**

This formula will calculate age as of** January 1, 2025.**

## Conclusion

Calculating age in Excel is a simple, effective way to manage data. YEARFRAC and DATEDIF formulas compute ages with precision. They work in years, months, or days. These functions save time and improve accuracy. They reduce manual calculations. Excel’s powerful functions can track birthdays, job lengths, or insurance policies. They will complete it with efficiency. Now that you know these formulas, use them in real life to streamline your work.
