Question

 Last Cost is $400 and Minimum Markup GP % is set to 10%.  Jiwa has calculated it to be $444.44.  What's the formula for that calculation?

Answer

The formula is Last Cost / (1 - MinimumGP / 100) to the precision of the MoneyDecimalPlaces system setting.

In this case of last cost of $400 and a MinimumGP % of 10%, that's:
400 / ( 1 - 10 /100) 
= 
400 / (1 - 0.1)
=
400 / 0.9
=
444.44

For completeness - this is the code used to calculate the MinimumSellPrice property:

To work backwards:

Sell Price - Last Cost = GP (444.44 - 400 = 44.44)

GP% = GP / Sell Price

GP% = 44.44 / 444.44

GP% = .099999999 (~.10)
