I Paid for Everything With Cash for a Month. Here’s What I Learned

As she points out, there are lots of reasons not to use cash, including less germs and not having to wait for someone to make change. Going cash-free also benefits businesses, since the cashier doesn’t have to count every bill and coin at the end of their shift to make sure what’s in the till reflects the completed transactions.

There’s also an advantage for consumers. Reverse ATMs make some customers, myself included, think twice before making a purchase. In fact, the cashier at the ice cream shop told me she’d had several potential cone-lickers walk out when they learned they couldn’t pay with cash, leaving her with melting scoops to discard.

Lesson 3: Spare change adds up

Like many households, my husband and I keep a ceramic bowl on a dresser in which we toss loose change. Over time, it has become a cluttered repository of coins, plus the occasional mystery button.

One afternoon, short on cash, I brought the bowl to a Coinstar machine at my local supermarket. Coinstar offers an option to convert coins into gift cards or cash, but choosing cash comes with a hefty service fee of between 11.9 and 12.9 percent, depending on the location, plus a transaction fee of 99 cents. If I hadn’t needed the cash, I could have avoided the fees by choosing an e-gift card for a retailer (Apple, Starbucks or Southwest Airlines, for example), or by donating to charity through the Coinstar Cares program.

Although the machine tallied my haul as $76.91, I left with $66 in cash — a lot more than I had in my wallet when I started.

Lesson 4: Amazon is efficient and affordable, yet predictably impersonal

Before my cash experiment, I made a significant portion of my household purchases on Amazon. Running low on vitamins or toilet paper usually involved a few taps on my phone and waiting for packages to appear within days, or even hours.

Switching to in-person shopping changed more than my spending habits. It changed my daily interactions.

I started asking cashiers whether customers still pay with cash. Most said no. One laughed and said, “Weirdly, yes!” Others seemed confused by my enthusiasm for small talk about payment methods.

What surprised me most was how much I enjoyed these interactions. Paying in cash slowed transactions enough to create space for eye contact, brief conversation and, occasionally, jokes about dwindling coin supplies. While I sometimes paid a little more by shopping at brick-and-mortar stores, the sense of connection felt worth it.

Macksoud says such experiences can be valuable. “It’s not just the item we buy, it’s the full experience of spending,” she explains. “Touching products, interacting with people and being present during the purchase can create more satisfaction than clicking ‘buy now.’”

Lesson 5: Some businesses offer financial incentives if you pay with cash

Many businesses still encourage cash payments.

Several merchants told me that credit card processing fees, which typically range from 1.5 to 3.5 percent, significantly cut into their profits. Some businesses pass those costs on to customers, and not always transparently.

The nail salon I frequent charges customers an extra 3 percent fee for paying with a credit card before taxes are applied.

Lesson 6: Loyalty rewards are less free than they feel

One of the hardest adjustments during my experiment was losing access to rewards programs. No Starbucks stars. No airline miles. No rideshare points. With every transaction, I felt like I was forfeiting tiny future luxuries.

But loyalty rewards programs can be a double-edged sword, Macksoud warns, in that they create a subtle spending trap. “We’re addicted to points,” she says. “That’s the carrot they dangle. By the time you factor in transaction fees and extra spending to earn rewards, you’ve often paid for the ‘free’ coffee.”

I experienced this dynamic firsthand. Without reward incentives, I found myself weighing purchases more carefully. Did I really want that latte, or was my eye on the elusive one that I’d get for free after buying 10 of them?

Lesson 7: Digital transactions make it easier to hit “buy” on pricey items

Perhaps the most dramatic change I noticed over the month was how paying in cash reshaped my impulse-buying habits.

Without credit cards or digital wallets, late-night scrolling became less financially risky. Instead of immediately purchasing items advertised on social media that I suddenly had to have, I implemented a strategy: When something caught my eye, I opened the ad in my browser, emailed it to myself and filed it under the label “Buy Me, Maybe.”

By the end of January, I’d amassed dozens of unread emails, and my bank account was noticeably healthier. I estimate I saved several hundred dollars by postponing purchases long enough to lose interest in them.

Perhaps that’s no surprise, though, considering that research shows digital payments can create emotional distance from spending, making purchases feel less consequential.

Alex Belli, a senior lecturer in marketing at the University of Melbourne in Australia, studies the “cashless effect,” in which consumers tend to spend more when using digital payment methods.

“Because cash is finite, it will dictate the maximum amount you can spend,” Belli says. “Having a specific amount of cash in your wallet can act as a form of financial self-control.”

His research shows that people may spend more when making status-related purchases like branded clothing or designer sunglasses using cashless payments, where the psychological friction of spending is lower.

The bigger picture: A rapidly changing payment landscape

Cash usage continues to decline. According to the Federal Reserve’s 2025 Diary of Consumer Payment Choice survey, cash accounted for just 14 percent of U.S. consumer payments in 2024, compared to 35 percent for credit cards and 30 percent for debit cards.

One reason credit card usage continues to climb is the rewards points or cash back that many cards offer. A 2025 American Bankers Association survey conducted by Morning Consult found that 4 in 5 Americans have at least one credit card that offers rewards. Whether you receive 5 percent cash back for buying groceries, 3 percent for gassing up or 2 percent for dining, those savings accumulate over time.

But keep in mind that credit cards aren’t as altruistic as they appear. If you fail to make monthly payments, you’ll pay interest on the balance. That’s money you could be socking away for a rainy day or investing in timeless clothing items. And as of early March, the average variable interest rate was an eye-popping 19.58 percent, according to Bankrate.

Mobile payments are becoming increasingly popular. An estimated 65.6 million Americans currently use Apple Pay, a figure projected to reach approximately 84 million by 2030, according to Capital One Shopping research.

Still, experts caution against abandoning cash completely. Belli suggests carrying a modest amount of cash as a budgeting tool. “If you’re going out for coffee, maybe $10 is enough,” he says. “If you’re grocery shopping, $100 to $150 might be appropriate. Cash naturally limits spending.”

Macksoud encourages occasional cash experiments for anyone curious about their financial habits. “If people spend a week or month using cash, they often recognize the true cost of running their lives,” she says.

Would I do it again?

Living on cash wasn’t convenient. It required planning, patience and a noticeably heavier wallet. But the effort definitely paid off in other ways.

I became more aware of where my money was going, and more intentional about how I spent it. I supported local businesses more frequently. And I experienced brief yet meaningful interactions that rarely occur during digital transactions.

Most importantly, I gained clarity about which purchases genuinely improved my life and which were simply force of habit, like subscribe-and-save paper products from Amazon or the irresistible end-of-season sale items (“up to 70 percent off!”) that I often hang in my closet and forget about by the following year.

Will I give up credit cards entirely? Probably not. They remain useful for travel, fraud protection and large purchases. And, oh, how those rewards add up over time! A few years ago, my husband and I flew premium economy to Thailand using miles earned from our travel credit card.

But I now view cash less as a nostalgic relic and more as a tool that helps me be more mindful of my spending decisions and more connected to my money, my choices and my community. That feels like a strong way to start the year.
