Calculate expiration date

Deanna Copello

Dependencies are off.

How do I calculate an expiration date from two cells below:

Contract term in months (drop down menu 12, 24, 36, 60)

Contract begin date

Need calculation is Contract Expire Date

Thank you!

Sorry about that. Leave it to me to miss a closing parenthesis. Try this...

=IFERROR(DATE(YEAR([Contract Start Date]@row) + ROUNDDOWN((MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row)) / 12, 0) + IF(IF(MOD(MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row), 12) = 0, 12, MOD(MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row), 12)) = 12, -1) - IF(AND(ABS(VALUE([Contract Term in Months]@row)) - MONTH([Contract Start Date]@row) <> 12, VALUE([Contract Term in Months]@row) < 0, ABS(VALUE([Contract Term in Months]@row)) > MONTH([Contract Start Date]@row)), 1, 0), IF(MOD(MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row), 12) = 0, 12, MOD(MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row), 12)), DAY([Contract Start Date]@row)), DATE(IF(MONTH([Contract Start Date]@row) - ABS(VALUE([Contract Term in Months]@row)) < 1, YEAR([Contract Start Date]@row) - 1, YEAR([Contract Start Date]@row)), IF(MONTH([Contract Start Date]@row) - ABS(VALUE([Contract Term in Months]@row)) < 1, MONTH([Contract Start Date]@row) + (12 - ABS(VALUE([Contract Term in Months]@row))), MONTH([Contract Start Date]@row) - ABS(VALUE([Contract Term in Months]@row))), DAY([Contract Start Date]@row)))

Try this:

=IFERROR(DATE(YEAR([Original Date]@row) + ROUNDDOWN((MONTH([Original Date]@row) + VALUE([Number Of Months]@row)) / 12, 0) + IF(IF(MOD(MONTH([Original Date]@row) + VALUE([Number Of Months]@row), 12) = 0, 12, MOD(MONTH([Original Date]@row) + VALUE([Number Of Months]@row), 12)) = 12, -1) - IF(AND(ABS(VALUE([Number Of Months]@row)) - MONTH([Original Date]@row) <> 12, VALUE([Number Of Months]@row) < 0, ABS(VALUE([Number Of Months]@row)) > MONTH([Original Date]@row)), 1, 0), IF(MOD(MONTH([Original Date]@row) + VALUE([Number Of Months]@row), 12) = 0, 12, MOD(MONTH([Original Date]@row) + VALUE([Number Of Months]@row), 12)), 1), DATE(IF(MONTH([Original Date]@row) - ABS(VALUE([Number Of Months]@row)) < 1, YEAR([Original Date]@row) - 1, YEAR([Original Date]@row)), IF(MONTH([Original Date]@row) - ABS(VALUE([Number Of Months]@row)) < 1, MONTH([Original Date]@row) + (12 - ABS(VALUE([Number Of Months]@row))), MONTH([Original Date]@row) - ABS(VALUE([Number Of Months]@row))), 1))

Hi @Deanna Croach

I hope you're well and safe!

Did you change the Column names to match yours?

I hope that helps!

Be safe, and have a fantastic weekend!

Best,

@Deanna Croach

Easy to miss!

Paul Newcome

Yes. My suggestion for changing column names is to copy/paste the formula into a notepad doc the using CTRL+H to find/replace the sample column names with your sheet column names.

Deanna Copello

Hi again! The formula ALMOST worked. it calculated the month and year correctly, but it defaulted to 01 for the day. how do i change this?

=IFERROR(DATE(YEAR([Contract Start Date]@row) + ROUNDDOWN((MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row)) / 12, 0) + IF(IF(MOD(MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row), 12) = 0, 12, MOD(MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row), 12)) = 12, -1) - IF(AND(ABS(VALUE([Contract Term in Months]@row)) - MONTH([Contract Start Date]@row) <> 12, VALUE([Contract Term in Months]@row) < 0, ABS(VALUE([Contract Term in Months]@row)) > MONTH([Contract Start Date]@row)), 1, 0), IF(MOD(MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row), 12) = 0, 12, MOD(MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row), 12)), 1), DATE(IF(MONTH([Contract Start Date]@row) - ABS(VALUE([Contract Term in Months]@row)) < 1, YEAR([Contract Start Date]@row) - 1, YEAR([Contract Start Date]@row)), IF(MONTH([Contract Start Date]@row) - ABS(VALUE([Contract Term in Months]@row)) < 1, MONTH([Contract Start Date]@row) + (12 - ABS(VALUE([Contract Term in Months]@row))), MONTH([Contract Start Date]@row) - ABS(VALUE([Contract Term in Months]@row))), 1))

Disregard the question of the one off months (for internal company discussion)

Paul Newcome

We just need to include the DAY portion in the DATE functions. Sorry about that.

=IFERROR(DATE(YEAR([Contract Start Date]@row) + ROUNDDOWN((MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row)) / 12, 0) + IF(IF(MOD(MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row), 12) = 0, 12, MOD(MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row), 12)) = 12, -1) - IF(AND(ABS(VALUE([Contract Term in Months]@row)) - MONTH([Contract Start Date]@row) <> 12, VALUE([Contract Term in Months]@row) < 0, ABS(VALUE([Contract Term in Months]@row)) > MONTH([Contract Start Date]@row)), 1, 0), IF(MOD(MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row), 12) = 0, 12, MOD(MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row), 12)), DAY([Contract Start Date]@row), DATE(IF(MONTH([Contract Start Date]@row) - ABS(VALUE([Contract Term in Months]@row)) < 1, YEAR([Contract Start Date]@row) - 1, YEAR([Contract Start Date]@row)), IF(MONTH([Contract Start Date]@row) - ABS(VALUE([Contract Term in Months]@row)) < 1, MONTH([Contract Start Date]@row) + (12 - ABS(VALUE([Contract Term in Months]@row))), MONTH([Contract Start Date]@row) - ABS(VALUE([Contract Term in Months]@row))), DAY([Contract Start Date]@row))

Deanna Copello

hmm, #incorrect argument set......

Paul Newcome

Sorry about that. Leave it to me to miss a closing parenthesis. Try this...

=IFERROR(DATE(YEAR([Contract Start Date]@row) + ROUNDDOWN((MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row)) / 12, 0) + IF(IF(MOD(MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row), 12) = 0, 12, MOD(MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row), 12)) = 12, -1) - IF(AND(ABS(VALUE([Contract Term in Months]@row)) - MONTH([Contract Start Date]@row) <> 12, VALUE([Contract Term in Months]@row) < 0, ABS(VALUE([Contract Term in Months]@row)) > MONTH([Contract Start Date]@row)), 1, 0), IF(MOD(MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row), 12) = 0, 12, MOD(MONTH([Contract Start Date]@row) + VALUE([Contract Term in Months]@row), 12)), DAY([Contract Start Date]@row)), DATE(IF(MONTH([Contract Start Date]@row) - ABS(VALUE([Contract Term in Months]@row)) < 1, YEAR([Contract Start Date]@row) - 1, YEAR([Contract Start Date]@row)), IF(MONTH([Contract Start Date]@row) - ABS(VALUE([Contract Term in Months]@row)) < 1, MONTH([Contract Start Date]@row) + (12 - ABS(VALUE([Contract Term in Months]@row))), MONTH([Contract Start Date]@row) - ABS(VALUE([Contract Term in Months]@row))), DAY([Contract Start Date]@row)))

works perfectly! thank you!!!
