One small quibble, you can actually live much more cheaply on rice. A pound of dry rice contains 1600 calories, if you eat 2000 calories a day, you need 5 pounds every 4 days, so a 50 pound bag will last 40 days, meaning you need 9 per year. This has a total cost of $450 at your price. Probably less if you shop around or buy in bulk.

Thanks. In my calculations, I used 600 Calories per pound of rice, which is wrong.
