Not all frugal advice is created equal.
For every genuinely useful money-saving tip, there’s another piece of advice floating around that sounds reasonable on the surface but can actually cost you more in the long run or just doesn’t hold up to scrutiny.
Here are ten of the worst pieces of frugal advice people have actually received (yes, these are real and yes, you should ignore them)
Rent Your Furniture
Rent-A-Center and similar rent-to-own furniture stores are often recommended to people who don’t have money saved to buy outright. The pitch is that the payments are cheaper and more manageable.
In reality, rent-to-own arrangements almost always end up costing significantly more than the item’s retail price over time. It might feel like a solution in the short term, but it’s one of the more expensive ways to furnish a home.
Don’t Work Overtime — It’ll Push You Into a Higher Tax Bracket
This one is remarkably common and remarkably wrong.
The concern is that earning more through overtime will push you into the next tax bracket and leave you with less to take home.
That’s not how tax brackets work.
In the U.S., tax brackets are marginal, meaning only the income above a threshold is taxed at the higher rate, not all of your income.
Working overtime will always result in more money in your pocket, not less.
(But working overtime can push you over the benefits “cliff,” so if that is a concern, then you should definitely make sure you make the right choice when it comes to benefits.)
Never Throw Anything Out — You Might Use It One Day
Holding onto everything “just in case” sounds frugal in theory, but in practice, it creates a different kind of problem.
Homes fill up with items that never get used, and when something is actually needed, it often can’t be found in the clutter, so a new one gets purchased anyway.
The result is two identical items, neither of which can be located. A more practical approach: sell the things you don’t need and get cash for your clutter.
Buy a New Car
This one comes up in two different forms and both are worth addressing.
The first is social pressure: friends or family insisting you should upgrade from an older car simply because you can afford to.
The second, somehow worse, is the claim that buying a brand-new car is “the best investment one can make.”
A new car depreciates the moment it leaves the lot.
An older car that requires only basic maintenance, meanwhile, can run reliably for years at a fraction of the cost.
New luxury vehicles, as many owners find out, come with their own expensive and frequent service visits.
Cars are not an investment. Investments make you money and get more valuable over time. Cars do neither.
Don’t Buy Secondhand
The idea that secondhand shopping is only for people who have no other option is both outdated and inaccurate.
Thrift stores and secondhand shops are full of clean, barely used items available at a fraction of the price of new.
Buying secondhand is a smart, practical way to save money, and it’s better for the environment too.
Have Kids for the Tax Deductions
This advice is exactly as questionable as it sounds. While there are tax benefits to having children, they are nowhere near enough to offset the actual cost of raising a child.
Childcare alone is notoriously expensive, and it can reach a point where two work-from-home parents can’t juggle their jobs and a toddler, meaning childcare becomes unavoidable and costly.
The tax deduction is a minor perk at best, not a financial strategy.
Always Buy the Cheapest Option
Being frugal and being cheap are not the same thing.
A higher price doesn’t guarantee higher quality, but a lower price does tend to guarantee lower quality.
Consistently buying the cheapest available option often means replacing things sooner, spending more on repairs, or simply ending up with something that doesn’t work well.
Frugality is about value, not just low price tags.
Never Use Credit Cards
Avoiding credit cards makes sense if you can’t pay off the balance in full each month, but as a blanket rule, it leaves a lot of money on the table.
When used correctly, meaning paying down the entire balance before interest accrues, credit cards offer reward points that translate into real value.
Flights, hotels, rental cars, and large purchases can all be offset or covered entirely by points accumulated through regular spending. Used responsibly, credit cards aren’t a trap; they’re a tool.
Dave Ramsey says this a lot, and while it may be a drastic measure that works for people who struggle intensely with overspending, for the vast majority of the population, this just doesn’t hold true.
It’s Cheaper to Eat Out Than Cook at Home
This narrative has been gaining steam, particularly as inflation has made groceries more visible in people’s budgets. But it doesn’t hold up.
Frozen and canned vegetables, bagged dry goods, in-season produce, and shopping exclusively from sales make home cooking consistently cheaper than dining out.
Even buying fresh produce, you can feed a family of three multiple times for roughly what a single takeout order costs.
Eating out has its place, but framing it as the budget-friendly option simply isn’t accurate.
Don’t Get Rid of Anything (Revisited as “Keep Everything Just in Case”)
Worth a second mention because it shows up in so many forms: from parents advising adult children to hold onto every item they’ve ever owned, to well-meaning people insisting that clutter is just “future savings.”
The frugal reality is the opposite: unused items have value, and selling them puts money back in your pocket.
Holding onto things indefinitely, on the other hand, costs you space, time, and sometimes money when you end up buying a duplicate of something you already own but can’t find.
Bad financial advice often sounds sensible; that’s what makes it stick around. Knowing which “frugal” tips to ignore is just as important as knowing which ones to follow.
