Investing is something we all need to do.

Once you’ve got a solid financial foundation—an income, an emergency fund, and you’re able to cover your bills and save a bit every month—investing is one of the most important things to tackle on your financial to-do list. It’s the best move you can make for your long-term savings, like the money you’re stashing away for retirement, because it’s the only way you’ll be able to outpace inflation and retire comfortably someday.

Think about this: to save up a million dollars without investing it, you’d need to put $2380 aside every month between the ages of 30 and 65. 

If you invested your money starting at 30, and earned a 5% return after fees, you could end up with a million dollars by only putting away $900 every month. Sure, that’s still $900 a month, but it’s $1480 less than you’d need to stash away without investing your money.

That said, investing is a complex topic, and people spend entire university degrees and careers studying it. Luckily, you don’t need to get that deep to set up an investing approach that works for you—and it’s so much easier than you think it’s going to be.
