Using the oil packets and purchasing the most cost effective plan (28 bags for 255/month), Soylent gives you 220 calories per dollar. For a relatively sedentary averaged sized adult male (2100 calories/day), it will cost you about $285/month. Ensure powder from Amazon[0] gets you to about 205 calories per dollar, which comes to $305/month for the same adult male. I don't buy the 'it's a lot cheaper than Ensure' line. Another competitor, "Optimum Nutrition Serious Mass" is on Amazon in 12 pound bags for $49. It works out to 408 calories per dollar. Only $154/month for the same example male. Admittedly Ensure and Serious Mass have different marketing than Soylent (Ensure for old people and Serious Mass for bodybuilders), but if you compare their ingredients you'll find they aren't very different.
