These days, savers can get better returns on their cash than they have in nearly two decades.
Following a series of rate hikes by the Federal Reserve, interest rates on the highest-yielding online savings accounts are now above 5%, according to Bankrate.com.
“Moving your money into a high-yield savings account is the easiest money you’ll ever make,” said Greg McBride, chief financial analyst at Bankrate.com.

But some people are foregoing competitive returns altogether in favor of literally keeping cash at home.
How does cash top-up work?
After gaining popularity on TikTok, more young adults are trying the so-called envelope method or “To top up cash, stay on budget and get out of debt.
The logic is simple: Spending money is divided into envelopes that represent your monthly expenses, such as food and gas. When the cash in an envelope is spent, you either run out of spending in that category for that month or you need to borrow from another envelope.
“There’s a back-to-basics mentality,” said Ted Rossman, senior industry analyst at Bankrate.
He said such tools could help enforce discipline and were “a reasonable way to stay on budget.”
But he added that this was not the “ideal scenario.”
Some disadvantages of holding cash
Storing cash not only waives the protections of consumer banking, it could also leave you deserted. vulnerable to theft.
Whether you are covered in the event of theft may depend on your home insurance policy; whereas banks are covered by the FDIC, which insures your money up to $250,000 per depositor per account holder category.
There’s also the added cost that McBride points out: Missing out on the opportunity to earn up to 5% on your savings.

“Overall, introducing the idea of budgeting is probably a positive thing, but if people are turning to cash instead of taking advantage of the highest returns we’ve seen in a long time on high-yield savings accounts, then it’s leaving money on the table,” said Matt Schulz, chief credit analyst at LendingTree.
For example, if you have $5,000 in a high-yield savings account earning 5%, you’ll earn $250 in interest per year.
“When you live paycheck to paycheck, every little bit helps,” Schulz said.
Alternatives such as Treasury bills, certificates of deposit, or money market accounts have also emerged as competitive options for cash; but this may mean tying up your savings for several months or longer.
