Higher returns mean taking on more risk, and the risk is real
The investments with the highest historical returns are stocks and stock funds, followed by bonds, then savings accounts and money market accounts. But "highest return" is not the same as "best for you." A stock that gained 40% last year can lose 30% the next year. A savings account earns less but will not drop in value. The trade-off between return and safety is not negotiable—it is how markets work.
Before you chase the highest number, you need to know three things: how long you can leave the money untouched, whether you can stomach watching it drop in value without selling, and whether you have other money to live on if things go wrong. Those answers matter more than the return itself.
Key Takeaways
- Stocks historically return around 10% per year on average over decades, but individual years swing wildly—some years up 30%, some years down 20%.
- Bonds typically return 3% to 6% per year and are less volatile than stocks, but still move with interest rates and credit risk.
- High-yield savings accounts and money market accounts currently return 4% to 5% with no risk of losing your principal, but that rate changes with Federal Reserve decisions.
- The longer your time horizon, the more you can afford to own stocks; the shorter it is, the more you need stability.
- Mixing stocks, bonds, and cash—called diversification—reduces the damage from any single investment falling, but it also reduces the highest possible gain.
Why stocks have the highest long-term returns
Stocks represent ownership in companies. When a company grows and becomes more profitable, its stock price rises. Over the past 100 years, the S&P 500—an index of 500 large U.S. companies—has returned about 10% per year on average. That is much higher than bonds or savings accounts.
But that 10% is an average. In some years the market gained 30% or more. In other years it lost 20% or more. The 2008 financial crisis saw stocks drop nearly 40% in a single year. If you needed that money in 2009, you would have locked in a loss. If you left it alone, you would have made it back by 2013 and then some.
This is why stocks work best for money you will not need for at least five to ten years. The longer you hold, the more likely you are to ride out the bad years and capture the good ones. For money you need in the next two years, stocks are the wrong tool.
Bonds return less but with less drama
A bond is a loan you make to a government or company. They pay you interest—usually 3% to 6% per year depending on the type and current conditions. When the bond matures, you get your principal back. Bonds are less volatile than stocks because the interest payment is fixed and promised.
But bonds are not risk-free. If interest rates rise, the value of existing bonds falls (because new bonds now pay more). If a company or government defaults, you may lose money. Bond funds—which hold many bonds—smooth out some of this risk, but they do not eliminate it.
Bonds fit between stocks and savings accounts. They are appropriate for money you might need in five to ten years, or for part of a longer-term portfolio that you want to be less volatile than pure stocks.
High-yield savings and money market accounts are the safest option
High-yield savings accounts and money market accounts currently pay 4% to 5% per year. Your money is insured by the FDIC up to $250,000, so you cannot lose your principal. The trade-off is that the rate changes with Federal Reserve decisions—when the Fed cuts rates, your rate drops too.
These accounts are appropriate for money you need within one to three years, or for an emergency fund you want to access quickly without risk. They will not make you wealthy, but they will not surprise you with a loss either.
The rate you see today is not permanent. In 2021, high-yield savings paid less than 1%. By 2023, they paid 5%. By the time you read this, the rate may have changed again. Check your bank's current rate before opening an account.
How time horizon shapes which investment makes sense
The longer you can leave money untouched, the more volatility you can tolerate, and the higher your potential return. This is called your time horizon.
| Time Horizon | Best Fit | Why |
| Less than 1 year | High-yield savings or money market | You need the money soon and cannot afford a loss. |
| 1 to 3 years | High-yield savings, short-term bonds, or mostly cash | Some growth is possible, but a stock crash would hurt. |
| 3 to 7 years | Mix of bonds and stocks (60% bonds, 40% stocks) | You can ride out one bad year but not a long downturn. |
| 7+ years | Mostly stocks (70% to 100%), with some bonds for stability | You have time to recover from crashes and capture growth. |
Diversification reduces risk without killing returns
Putting all your money in one stock or one bond is dangerous. If that company fails, you lose everything. Spreading money across many stocks, bonds, and cash reduces that risk. When stocks fall, bonds often hold steady. When bonds fall, cash does not move.
A simple diversified portfolio might be 60% stocks, 30% bonds, and 10% cash. Over the long term, this mix returns less than 100% stocks, but it also loses less in bad years. For most people, that trade-off is worth it.
You do not have to pick individual stocks or bonds. Index funds and target-date funds do the diversification for you. An index fund tracking the S&P 500 gives you ownership in 500 companies with one purchase. A target-date fund automatically shifts from stocks to bonds as you approach retirement.
What "highest return" actually costs you
Chasing the highest possible return often means paying fees, taking on hidden risks, or locking your money away. A stock that returned 50% last year might return negative 30% this year. A bond fund that promises 8% might be holding risky corporate debt. A certificate of deposit (CD) that locks in 5% means you cannot access the money for months or years without a penalty.
The highest return that matters is the one you can actually stick with. If you buy a volatile stock fund and panic-sell when it drops 20%, you lock in the loss. If you buy a CD and need the money early, you pay a penalty that wipes out the gain. If you chase a hot stock tip and it crashes, you lose money you needed.
A boring portfolio of index funds and high-yield savings that you leave alone will almost always beat a flashy strategy you abandon halfway through.
Frequently Asked Questions
Can I get 10% returns in a savings account?
No. High-yield savings accounts currently pay around 4% to 5%. Anything promising 10% or higher is either a scam, a very risky investment (like stocks), or a promotional rate that expires after a few months. Read the fine print.
Is it too late to start investing if I am older?
It depends on when you need the money. If you retire in five years, stocks are risky because a crash could wipe out gains right when you need to withdraw. If you retire in 20 years, stocks still make sense for part of your portfolio. Talk to a financial advisor about your specific timeline.
What if I cannot afford to lose money?
Then stocks are not for you. Use high-yield savings accounts, money market accounts, or CDs. They will not make you wealthy, but they will not surprise you with losses either. Stability is a valid choice.
Do I need to pick individual stocks to get high returns?
No. Most individual investors underperform index funds because they buy high and sell low. An S&P 500 index fund gives you exposure to 500 companies with one low-cost purchase. That is enough for most people.
What happens to my returns if interest rates drop?
High-yield savings rates drop with Federal Reserve rate cuts. Bond prices rise (because older bonds paying higher rates become more valuable), but new bonds pay less. Stock returns depend on company profits, not interest rates directly, though lower rates can help stocks rise.
