A while back, I posted about price-per-gram of mineral foundations. Some things have changed, namely - Aromaleigh's products are no longer available. :( And Everyday Minerals appears to have kiboshed the 45% discount on stuff, therefore killing their spot as least-expensive mineral makeup. Way to go, EDM! Also, I added a rough estimate for Sassy Minerals, which wasn't around when I first made the list.
Remember, different brands have different densities even if they fill the same size jar, and different brands can require different amounts of product for equivalent coverage.
Keep in mind that most MMU companies pack by volume, not by weight, so the weights are approximate.
If I missed a company - and you know how much their foundation costs and how much (in grams) you get, let me know and I'll add it.

Note: Silk Naturals sells unmixed foundation by volume, not by weight, and a tablespoon of their foundation would fit into a 25g jar, which is a pretty standard size. You buy a bag of plain white foundation and mix the appropriate amounts of darker base colors into them, so you get an exact match. Both the white base and the colors you add to it are available in tablespoon bags and half teaspoon sample baggies.
They also use different ingredients that aren't as dense as other companies (silk powder, for example), so a tablespoon ranges from 4-5.8 grams depending on formula, with the lighter coverage being less dense than the heavier ones. The cost per gram is different between formulas, but the cost per volume is the same. For purposes of comparison with other brands, it's more useful to think in terms of volume:
As sold by the tablespoon in plastic baggies, the unit price works out to:
$1.37/g for original formula
$1.10/g for the vegan and medium formulas
$0.95/g for the heavy formula.
Since they come in baggies, you'll have to order your own jar (if you don't do the starter kit), and that'll add up to $1.50 to the cost. Or you could clean an old one out and use that - you're paying for product, not for packaging.
If you get the starter kit, which includes tablespoons of your base color, Ivory, a jar, and a scoop to measure:
Original formula: $1.50/g
Medium and vegan formulas: $1.20/g
Heavy formula: $1.03/g
