When Should I Start Investing?
The best time to start investing was your first paycheck; the second best time is today, and the math proves why waiting is so costly.
The question comes up all the time: "When should I start investing?" The straight answer is simple. The best time was the day you got your first paycheck. The second best time is today.
Now, that answer has some fine print. You do not want to throw money into the market while your financial house is on fire. So let's walk through what "today" really means, and what needs to be true before you buy your first share of anything.
Time in the market beats timing the market
Here is the reason folks say "start now" and mean it. Money grows on money, and that snowball needs years to get rolling. This is compound growth, and it rewards patience more than brilliance.
Picture two people who both invest $200 a month and both earn a 7 percent average annual return, which is a reasonable long-run assumption for a broad stock index after inflation. Person A starts at age 25. Person B waits until 35. Same monthly amount, same return, ten years apart.
By age 65, Person A has put in $96,000 of their own money and ends up with roughly $525,000. Person B put in $72,000 and ends up with roughly $244,000. That ten-year head start, worth $24,000 in actual contributions, turned into a gap of nearly $280,000. The early money had more time to multiply, and time is the one thing you cannot buy back.
That is why waiting for the "perfect moment" is usually the most expensive decision you can make. Nobody rings a bell at the bottom.
Three boxes to check first
Starting today does not mean starting reckless. Before you invest a dollar in the market, I want three things in place.
A small starter emergency fund. Aim for $1,000 in cash you do not touch. This keeps a flat tire or a surprise dentist bill from becoming credit card debt.
No high-interest debt. If you are carrying a credit card at 24 percent, paying it off is a guaranteed 24 percent return. The stock market cannot promise you anything close to that. Knock out the expensive debt first, then invest.
Free money from work. If your job offers a 401(k) match, that is the exception to every rule above. A common match is 50 cents on the dollar up to 6 percent of your pay. On a $50,000 salary, contributing 6 percent means $3,000 of your money plus $1,500 free from your employer. Turning down a full match is leaving a raise on the table.
How much, and where to begin
You do not need a fortune to start. Most brokerages today let you buy fractional shares, so $25 or $50 gets you in the door. What matters is that you start and then keep going.
A sensible order for most people looks like this. First, contribute enough to your 401(k) to grab the full employer match. Next, open a Roth IRA if you qualify and work toward the annual limit, which is $7,000 in 2025 for folks under 50. After that, put more into the 401(k) or a regular taxable brokerage account.
For what to actually buy, a low-cost broad market index fund is the boring, sturdy answer. It spreads your money across hundreds of companies, so you are not betting the farm on one stock. Set up an automatic transfer on payday so investing happens without you thinking about it. The best system is the one you never have to remember.
What about a bad market?
Folks always worry they will start right before a crash. Here is the honest truth. You will invest through downturns. Everyone does. But when you are buying every month for the next 30 or 40 years, a down market is a sale, not a disaster. Your automatic $200 buys more shares when prices drop.
The people who get hurt are the ones who panic and sell at the bottom, then wait on the sidelines and miss the recovery. If your timeline is long, market dips are noise. Keep buying, keep your hands off the sell button, and let the years do the heavy lifting.
Bottom line: Start now, not someday. Get $1,000 in the bank, clear your high-interest debt, grab any employer match, then invest a steady amount every month in something simple and broad. The head start is worth more than any clever move you could make later.
One caveat: investing carries risk and returns are never guaranteed. The 7 percent figure here is a long-run average, not a promise, and some years will be red. Invest money you will not need for at least five years, and consider talking to a fee-only advisor about your specific situation.
