“A penny saved is a penny earned” sounds like solid advice until you ask what that penny is actually earning. In a typical savings account, the honest answer is close to nothing.
Saving and investing solve different problems
Saving and investing get talked about like they’re the same thing, but they serve different jobs in your financial plan. Saving means keeping money in a safe, liquid place so it’s there when you need it. It won’t grow much, and that’s fine, because growth isn’t the point. Building an emergency fund is the clearest example: keeping three to six months of expenses in a high-yield savings or money market account means you can cover a lapse in income, a medical bill, or a major repair without selling investments or going into debt to cover it.
Saving also makes sense for goals inside a five-year window, a house down payment, a car, or routine expenses like taxes and insurance. Money you’ll need soon shouldn’t be exposed to market swings.
Investing is where growth actually happens
Investing means buying securities, stocks, bonds, ETFs, index funds, with the expectation that they grow in value over a long time horizon, generally ten to twenty years or more. You take on more risk than you do with savings, and there’s no guarantee on any given year’s return. But the long-run historical data tells a clear story: since its inception in 1926, the S&P 500 has averaged a 10 to 11% annual return, a figure that dwarfs what a traditional savings account pays. National average savings account rates have historically sat around 0.06%, and even a strong high-yield account has often paid well under 1%. That gap compounds significantly over decades.
What investing actually buys you
Beyond retirement, regular investing in a brokerage account builds optionality for the years before retirement too, five to ten years out, when you might be buying a house or starting a family. Say you open a brokerage account with an initial $1,000 and contribute $500 a month. At an average 6% return, that account can grow to over $36,400 in five years. That’s the kind of number that turns “maybe someday” into an actual choice when the opportunity shows up.
Investing is also more liquid than people assume. You’re not locked out of your money the way you are with home equity; you can sell investments when you need to, though holding taxable investments for at least a year before selling generally qualifies you for a lower long-term capital gains rate instead of your regular income tax rate.
Why this matters for keeping pace with inflation
Inflation typically runs around 2 to 4% a year, though it spiked well above that recently, reaching roughly 6% in late 2021. A savings account paying a fraction of a percent doesn’t come close to keeping pace, which means money that sits in savings for years actually loses purchasing power. Investing is one of the few tools available to keep your money growing faster than prices are rising.
Before you invest, check these first
Before shifting money from saving to investing, make sure you have an emergency fund in place (or are actively building one), you’ve eliminated high-interest debt like credit cards, you’re current on lower-interest debt like student loans, and you’re contributing enough to any employer retirement match to capture the free money. Once those boxes are checked, a brokerage account becomes a reasonable next step, whether or not you have a specific goal in mind yet. Having accessible invested money gives you the freedom to say yes to opportunities as they come up, a wedding, a career change, or a move, without derailing your longer-term plan.
