How much (paper) cash should I keep on hand for an emergency?
Coming from an area that is hurricane prone, and seeing what happens to local businesses during evacuations/power outages/gas shortages, I think what you already have on hand should be sufficient. And it sounds like that's exactly what you're budgeting for.  I'd say 2 weeks worth of fuel and food costs, with the budget for each in line with riding out a natural disaster. True "Preppers" would say keep your money in gold buried in the backyard surrounded by land mines, but that's not perhaps what you're looking for. It is not uncommon for gas stations and grocery stores to revert to cash only sales, especially if they're not big chain operations. If the internet is out, or power is spotty, they may not be able to process CCs. Again, think smaller or more rural businesses. I have seen gas stations switch to cash only during gas shortages as well to help limit how much fuel people were buying.  $250 should get you through fine unless you drive a tank and need steak every night. You could probably go with less, but it's entirely dependent on your needs. As Joe rightly stated in his answer, if it's desperate enough times that you can't use a CC or debit card, cash may not even be useful to you.
