Calculated value in a custom field

Hi all,

I'm new to Marketo (just left Eloqua and am happy so far!) so excuse me if this is repetitive - I couldn't find it in the discussions.

In Eloqua, I could create a numeric calculated formula field.

My use case was simple: birthday coupons.
I had the birthday hard coded into the database and had another field populated with the contact's birthday plus 2 weeks. This allowed me to send coupons with hard expiration dates, instead of just saying "this expires in 2 weeks."

Is there a way to do this in Marketo?


Thanks,
Nick
