"Hi @jimthing 

Thats a good suggestion, I can definitely see how it would help. I'll pass this over to the site team and ask if it's something they can implement or even add something to help pages that can do the calculation for you. 

Thanks,

Dave "

Dave, it's a spreadsheet formula we specifically need. There is a third-party website that can give the answer, but this cannot be implemented on our own spreadsheets. 

Another suggestion would be to add the option to simply enter the FINAL price, instead of the pre-BPF price.
