Mark Cuban Says Most People Are Ignoring an Investment With a 30%–50% Return

Mark Cuban has never been shy about unconventional money advice. When asked how he'd use $100,000, the billionaire investor said he'd first eliminate credit card debt, then look through his annual budget for ways to create "transactional value" from his cash.

His example was surprisingly ordinary, advocating for buying replenishable essentials in bulk. Cuban has said those savings could reach 30% to 50%.

Here's how Cuban's strategy works to keep more of your money.

Why Cuban calls it an investment, not a savings habit

Most people think of bulk buying as frugal behavior. Cuban frames it as a guaranteed, risk-free return on deployed capital.

"It's so hard to make a return on regular investments that you're better off, when you see a sale, buying two years' worth of toothpaste when it's on 50% discount. That's an immediate return on your money," he told Vanity Fair. The return is locked in at the moment of purchase.

The math behind Cuban's 30%–50% savings claim

Consider a household that spends $1,200 a year on non-perishable essentials such as cleaning supplies, paper goods, canned foods, and personal-care products. Buying those items at a consistent 30% discount would save $360. A 50% discount would save $600.

Cuban specifically points to products such as toothpaste, shampoo, soap, and other replenishable items because the household already expects to buy them.

Everyday essentials are where the strategy makes the most sense

The strongest candidates are items you use regularly, and they don't spoil quickly. Toilet paper, toothpaste, detergent, trash bags, soap, canned foods, and certain household cleaners fit the bill. Cuban's own examples focus heavily on products that households repeatedly replenish.

The advantage comes from removing a future purchase from your budget at today's price. You aren't buying something simply because it's discounted. You're moving an expense forward because you already know you'll need it later.

Grocery prices make buying strategically more valuable

Food prices aren't moving uniformly, which makes timing purchases worthwhile. 

The latest BLS data shows food-at-home prices were 2.7% higher year over year in July 2026, while fruits and vegetables were up 5.1%, and nonalcoholic beverages rose 4.1%. Food away from home increased 3.4% over the same period.

Cuban's midnight grocery trips show how he thinks about savings

Cuban's deal-hunting habits started long before he became wealthy. On Bill Maher's Club Random podcast, he recalled shopping for groceries at midnight in his twenties because stores marked down food.

He remembered buying chicken and large bags of French fries for $1.29. The lesson wasn't about staying up late to shop. Cuban was watching prices and adjusting his buying time around them.

Bulk buying protects your budget from future price increases

Stocking up provides another benefit when prices rise. Cuban made a similar argument in 2025, encouraging consumers to buy household consumables before retailers replenished inventory at potentially higher prices during tariff uncertainty.

His advice was to focus on products you have storage space for and know you'll use. You aren't predicting the economy or trying to time financial markets. You're simply purchasing a necessary product when the price looks favorable.

Don't confuse a low unit price with a good deal

A giant package isn't automatically a bargain. Compare the price per ounce, roll, serving, or unit before buying, then consider how quickly your household actually uses the product.

A larger package could have a lower unit price while still creating waste if it expires or remains untouched. Storage matters, too. Cuban's strategy depends on having enough space to hold products you'll realistically consume.

Paying off credit card debt comes before stocking up

Cuban's bulk-buying advice sits behind debt repayment in his financial hierarchy. He has argued that paying down a credit card charging 15% or 20% effectively produces a guaranteed return at that rate. The case is even stronger with today's borrowing costs.

The Federal Reserve reported an average credit card APR of 20.94% in May 2026. Eliminating expensive debt should generally come before optimizing household purchases.

Cuban also values keeping cash available for opportunities

Once debt is addressed and useful bulk purchases are covered, Cuban has said he keeps remaining money in the bank, even when the return is low. His reasoning is about liquidity. Cash gives him the ability to act when an attractive opportunity appears without selling another investment.

For households, the same principle might mean maintaining an emergency fund or near-term cash reserve before putting every available dollar into longer-term investments.

Cuban's strategy works best as part of a bigger money plan

Cuban's bulk-buying advice is about looking at money before it leaves your account and finding opportunities to keep more of it. His approach starts with budgeting, eliminating expensive debt, and creating value from cash rather than assuming every dollar needs to be invested immediately.

That means identifying recurring purchases, watching unit prices, buying ahead when discounts are genuine, and redirecting the savings.

How bulk-buying savings compare with investment returns

The S&P 500 has historically returned roughly 10% annually, while Morningstar reported a 15.1% annualized 10-year return through January 2026 for a broad U.S. stock-market index. Bulk-buying savings don't compound, but they arrive immediately.

For comparison, the FDIC's national savings rate was 0.38% as of August 2026, while Bankrate's September 2026 national average was 0.63%.

Bottom line

Mark Cuban's 30%–50% return claim makes sense when the savings come from purchases you already planned to make. You could save money on groceries and household essentials by comparing unit prices, buying non-perishables when discounts are genuine, and avoiding quantities you'll never use.

The bigger opportunity comes afterward. Direct those savings toward high-interest debt, emergency savings, or investments so the money keeps working.
