Profit Margin on Custom Field

[dannystang]

Can't seem to figure this one out, searched everywhere. I am on 2.0.14

Price Modifier for Profit Margin = 10%. My Base price for X product = 100. Final Price $110

So far everything is perfect.

Cart Variant based on size tshirts (Small/Medium/Large) = $5 / $10 / $15 respectively.

Drop down has +5 / +10 / +15 now how can I create a price modifier for profit margin for the CART VARIANT?

In this particular case say I also want to increase by 10% and show (Small $5.5 / $11 etc)

Another words I am trying to markup the cost of the variant AND the product. I thought I could just increase it before plugin it into the cart variant price but then if I wanted to increase my variant price by a % in the future I would have to do this all over again.

If by any chance anyone knows the line and php code for math on custom fields I will just take Custom Field price * 1.10 and adjust in the future...

Thanks for any help in advance it seems like such a simple change but can't figure this out!

Ok, I am sure there is an easier way but since I still can't find it.

Myphpadmin
Virtuemart product customfields

Export to Excel and do calculation or I guess you can do it in sql.

So much easier than csvi tried that also.

Still I am sure there is a easier approach but can't figure it out...

Anybody please? How to make calculation rules apply to the custom fields as well?
