Calculate Age in Excel Based on DOB

Calculating someone’s age based on their date of birth (DOB) is a common task in Excel. To do this, you need to use a combination of formulas and functions to convert the DOB into an age. This article will explain the different ways you can use to calculate age in Excel.

Using the DATEDIF Function

The DATEDIF function is one of the easiest and most accurate ways to calculate age in Excel. This function takes three parameters – the start date, the end date, and the unit of time. The end date should be the person’s DOB, and the start date should be the current date. The unit of time should be set to “y” for years. The formula to use is:

=DATEDIF(start_date, end_date, "y")

This formula will give you the exact age of the person in years. If you want to get the age in months or days, you can change the unit of time to “m” or “d” respectively.

Using the YEARFRAC Function

The YEARFRAC function is another way to calculate age in Excel. This function takes two parameters – the start date and the end date – and returns the number of years between the two dates. The formula to use is:

=YEARFRAC(start_date, end_date)

This formula will give you the exact age of the person in years, but it will return a decimal value instead of a whole number. You can use the ROUND function to round the result to the nearest whole number.

Using the INT Function

The INT function is another way to calculate age in Excel. This function takes one parameter – a date – and returns the number of years since that date. The formula to use is:

=INT(end_date - start_date)

This formula will give you the exact age of the person in years, but it will return a decimal value instead of a whole number. You can use the ROUND function to round the result to the nearest whole number.

Calculate Age in Excel Based on Age Difference

If you want to calculate the age of a person based on the age difference between two people, you can use the following formula:

=end_date - (start_date - age_difference)

This formula will calculate the age of the person based on the age difference between two people. For example, if you wanted to calculate the age of a person who is 10 years younger than another person, you would use the following formula:

=end_date - (start_date - 10)

This formula will calculate the age of the person by subtracting 10 years from the start_date.

Using the DATEDIF Function with Age Difference

The DATEDIF function can also be used to calculate the age of a person based on the age difference between two people. The formula to use is:

=DATEDIF(start_date, end_date - age_difference, "y")

This formula will calculate the age of the person by subtracting the age difference from the end date. For example, if you wanted to calculate the age of a person who is 10 years younger than another person, you would use the following formula:

=DATEDIF(start_date, end_date - 10, "y")

Using the YEARFRAC Function with Age Difference

The YEARFRAC function can also be used to calculate the age of a person based on the age difference between two people. The formula to use is:

=YEARFRAC(start_date, end_date - age_difference)

This formula will calculate the age of the person by subtracting the age difference from the end date. For example, if you wanted to calculate the age of a person who is 10 years younger than another person, you would use the following formula:

=YEARFRAC(start_date, end_date - 10)

This formula will give you the exact age of the person in years, but it will return a decimal value instead of a whole number. You can use the ROUND function to round the result to the nearest whole number.

Frequently Asked Questions

How to Convert Dob to Age in Excel?

Answer:
To convert Dob to Age in Excel, you will first need to set up your worksheet. First, create a column for the date of birth (DOB). Next, create a column for the age. Finally, add a formula to calculate the age from the DOB.

The formula you will need to use is =DATEDIF(A1,TODAY(),”y”) where A1 is the cell containing the DOB. This formula will calculate the number of years between the two dates.

Once you have set up your worksheet and added the formula, you can then copy and paste the formula into the cells containing the DOB and the age will be calculated automatically.

What is the formula used to calculate the age from date of birth?

Answer:
The formula used to calculate the age from date of birth is =DATEDIF(A1,TODAY(),”y”). Here, A1 is the cell containing the DOB. This formula will calculate the number of years between the two dates.

What is the purpose of using the “y” parameter in the formula?

Answer:
The “y” parameter in the formula is used to specify that the result should be in years. This is necessary as the formula will otherwise calculate the number of days between the two dates, which is not what we want in this case.

Are there any other parameters that can be used in the formula?

Answer:
Yes, there are other parameters that can be used in the formula. For example, the “m” parameter can be used to calculate the number of months between two dates, and the “d” parameter can be used to calculate the number of days between two dates.

Can I use this formula to calculate age from any other date?

Answer:
Yes, this formula can be used to calculate the age from any other date. To do this, simply replace the “TODAY()” portion of the formula with the cell containing the other date.

Can I use this formula to calculate the number of years, months and days between two dates?

Answer:
Yes, you can use this formula to calculate the number of years, months and days between two dates. To do this, you will need to use the “ymd” parameter in the formula. This will calculate the number of years, months and days between the two dates and display the result in the cell.

How can I copy and paste the formula into multiple cells?

Answer:
To copy and paste the formula into multiple cells, you can use the “fill handle”. This is a small square box located at the bottom right corner of the cell containing the formula. Simply click and drag the fill handle to the cells you want to fill with the formula and the formula will be automatically copied into the cells.
