I’m comfortable with about $200.00 on me. Below $100.00 and I get nervous. If its more than $300, I hide most of it in a pocket of my hip pouch.
Hate using the cc for everything. I try hard NOT to uae a cc at mom 'n pop stores.
I’m 63.
About a $100 for emergencies after I got caught wanting to buy dinner after tornadoes knocked out the power for half the city. Apparently that was in 2018 and I don’t think I’ve used it since then. I use my credit card for everything.
$0. Credit card gives me money back.
About $25 for the typical day.
I start with a hundred bucks and get more when it gets down to about twenty. The one transaction for which I regularly need cash is my monthly haircut. For everything else I use my credit card.
Usually between 25 and 50 euros. I almost always pay with my debit card. The cash I carry is only for the few businesses that don’t take a card.
About 5 dollars. I don’t have more, but if I lost my bus pass, I would need it.
$3 or so. Just random ones that have found their ways into my wallet.
A $50 for the contingency that the debit/credit machine isn’t working. Been the same $50 for some years now.
For everyday walking around, I have a twenty-dollar bill folded up behind my phone in its case, which I can easily retrieve if there’s an unexpected need for a small amount of cash.
I just carry my driver’s license, a credit card, and my AAA card in a small pocket stuck to the back of the phone case, having abandoned the wallet altogether. Travel light; grab the phone and go. And I’m not even sure the AAA card is necessary because I don’t remember them asking for it the last few times I’ve called. I just feel it’s prudent to have it, just in case. The credit card is there only because not everybody is set up to let me tap the phone to pay. But overwhelmingly, most are. At least in my experience.
It is unusual for me to have more than $20 - usually closer to $5-10. Unless I am getting a haircut or something in which case I have $30-35. I rarely spend much cash. My wife gets cash over purchase at the grocery store - if I need more than $5-10 in my wallet, I’ll tell her I’m taking some out of hers. Weekly I’ll tip $5 at the coffee house where we play music and get free coffee. And the standard bet in my weekly golf game is $5 - today I lost a whopping $2. 
In fact, I don’t often even use my credit card. Gas, golf - that’s about it on a regular recurring basis.
I used to carry about $100 to $200. But in the last couple of years I’ve found that I essentially never use cash, so I pay less attention to it now. Yesterday I checked my wallet and was surprised to see that all I had was $10. That 10 has probably been alone in my wallet for months. I don’t even remember the last time I spent cash.
I don’t use cash often these days, but I try to make sure I have $60 or so in my wallet, at any given time, for:
- Paying the landscaping crew who mows my lawn every week
- Tipping my hair stylist
This is me. Except my emergency money is more like $200 rather than $20.
I find I rarely have emergencies, but when I do, $100 does not go as far as it used to. I can fill my gas tank & buy a Big Mac for $100, but there’s not much left. The main use for the emergency 20s is tipping the musicians since I never think to bring cash if I’m going to a live show at some sleazy dive.
I never spend cash at retail if there is any way to avoid it.
If I’m traveling that’s a separate situation that calls for some number of smaller denomination local currency and/or USD for the inevitable string of tips & small purchases that go hand in hand with travel. Day to day in (sub-)urban USA? Cash is a useless encumbrance. Until all else fails and you really need it.
Around $200 dollars in “contingency” money. I haven’t actually spent any of it for many years, but it’s there just in case.
At least $1000.
I carry somewhere between $20 and $200 in cash , but that
$200 might last a year. I almost never use cash - maybe if I’m buying just a coffee or a soda at a bodega/convenience type store.
My AAA membership only provided print-your-own paper or digital cards at my last renewal. And I haven’t been asked for the card in years.
Usually $50 for walking around money. I pay cash for anything under $20, with the exception of gasoline. Over $20 I’ll debit. I also carry 80 cents in change. Two quarters, two dimes, a nickel and five pennies. It’s an old habit that I often find useful.
I also carry spare change in all denominations primarily because the small towns I live in still have parking meters that will take nickles, dimes and sometimes quarters. Much cheaper than a parking violation ticket.
I typically carry at least $20 - $50 on a typical day. Much more when traveling.
$100 or less. I really seldom need cash unless I’m handing a grandchild a 20 for a birthday or something. Although yesterday I picked up the tab for the 5G burgers my eldest brought for lunch and that wiped out the hundred.
