Start with what covers the likely event, then extend.
Verdict
Most emergencies that actually happen to households last days, not weeks: a storm, an outage, a road closure. A three-day kit covers that and costs little. A thirty-day supply covers a genuine disruption and costs roughly ten times as much. Buy the three-day kit first and make sure it is complete; extend to thirty days once water, power and medication are also covered.

| Best for | Storms, outages, evacuation | Extended disruption |
You are starting out, or you want food that can leave with you. Three days is the standard planning figure for a reason: it covers the overwhelming majority of real events, and a kit small enough to carry is a kit you will actually take.

You have the basics covered and want depth, you live somewhere remote, or supply disruption is a realistic concern where you are. Cost per day drops substantially at this scale, but it is dead weight in an evacuation.

Check the per-day calorie figure rather than the day count, because kits vary widely and some assume around 1,200 calories a day. That is a survival ration, not a working diet, and it matters if you are doing physical work.
For long storage and light weight, yes. For home use, ordinary shelf-stable groceries you actually eat and rotate are cheaper and better. Many households do both: rotated pantry food for the first week, freeze-dried for depth.
Water to reconstitute it, and a way to heat that water. Freeze-dried food is useless without both. Also check that the kit suits any allergies or medical diets in the household before an emergency, not during one.
