Maybe they are just using a federal template, but they seem to underestimate a lot of the associated costs of living in Berkeley (California in general).
I can only use my personal experience for examples but my financial sheet estimates my off campus housing costs at just over $3,500 per semester when in reality a decent double is around $4,200 (800 a month) and a single is normally over $1,000 monthly. My food costs are also listed at $1200 which breaks down to about or $65 a week or $3 a meal which is very difficult to meet without buying bulk and cooking everything yourself. (I sure don’t have time to cook for myself.) Especially irritating to me is that they list my transportation costs at a mere $250 which doesn’t even pay for the gas for two round trips to SoCal via private automobile much less other modes of transportation.
