I am looking to create an addon for the backpage for Builders Risk Insurance (BRI). 

Currently BRI is being calculated as a Cost Basis "Total", based on the "Current Total." So the overall calculation is $0.14 x (Project Value / $100). That is good for a year, but when projects go over a year, it will not autocalculate. 

So basically, my formula needs to look like this:

[$0.14/12mo] x [(Project Total Value) / $100] x [Project Duration in months]
