Formula for Number of MONTHS to actual date?


We need to calculate results based on the number of months that have passed since a start date, basically a smarter version of this:

Number of months (since STARTDATE title actual date) * FEE = RESULT

Somehow this formula, which I think is pretty basic, cannot be found anywhere.
Doing some ‘MacGyvering’ with number of days divided by 30 is not cool enough;-)

Please Monday-Tribe, help us out!



Hi Erik,

You should be able to use the (hidden!) ‘YEARFRAC’ formula to work out the difference between your dates in years, then MULTIPLY that by 12:

MULTIPLY(YEARFRAC({Date 1}, {Date 2}),12)

You can then multiple that by your fee field.

Hope that helps and if there’s anything else we can help with, let us know!

Thanks, Daniel! Amazing how fast and friendly you are!

Oh, and I would add INT + () around your formula to get rounded numbers of months!:wink:
