These are the three steps to investing success: start soon, start small and keep it simple.

So this month I thought it would be useful to condense my top tips with a set of FAQs that crop up most often.

Successful investing hinges on just three steps: Start soon, start small, and keep it simple. It’s critical to start saving as soon as possible to take advantage of the power of compounding, which over time can have a bigger effect than how much you invest and where you put the money. Consider the case of two young women, Teri and Toni. At age 25, Teri begins contributing $2,000 a year to an IRA. She makes annual contributions for 10 years and then stops. Toni, on the other hand, waits until age 35 to start funding an IRA but makes regular $2,000 contributions for the next 30 years. If they both earn an average annual return of 8% in the stock market, who will have more money at age 65? Incredibly, Teri—a stunning illustration of compound interest working its magic. How do I know where to invest? That’s where “keep it simple” comes in. You can own shares in the entire U.S. stock market with a single investment in Vanguard’s Total Stock Market Index fund (VTSMX). If you also invest in Vanguard’s Total International Stock Index fund (VGTSX), you can literally own the world. Funds like these also make sense as core, long-term holdings for experienced investors. You can branch out into other investments as your interest and comfort level grow. Advertisement Another option is to invest in a single target-date fund, which is designed to divvy up assets among bonds as well as stocks in an age-appropriate mix until you need the money at some date in the future—usually at retirement. You’re likely to have access to a target-date fund through your retirement plan at work. Kiplinger’s likes target funds managed by Fidelity, T. Rowe Price and Vanguard. But I never have any money left at the end of the month to save, let alone invest. No matter how much you make, it always seems to disappear by the end of the month. Which is why I’ll add step number four: Invest steadily by having money taken right off the top of each paycheck. You can do that with an automatic contribution to your retirement account, or with a regular deposit to a bank account for a short-term goal, such as next year’s vacation. You can’t spend it if you don’t see it. How do I balance saving for retirement with saving for my kids’ college education? Retirement should always come first, especially for women, who tend to amass less in savings than men over the course of their careers. If you have a limited amount to devote to savings, your top priorities should be to build an emergency fund—aim to cover six to 12 months of expenses—and to put at least enough money into a retirement account to take advantage of any employer match. Can’t do that right away? Start smaller and work up to it. Once you have an emergency cushion, you can shift those payments to college savings. And don’t be afraid to tap the grandparents. Instead of letting them shower your kids with stuff, encourage them to open state-sponsored 529 college-savings accounts, for which they’re also likely to get a state tax break. (My husband and I are funding 529 accounts for all three of our grandchildren.)

I never skipped a contribution to my 401(k) account, even when the stock market tanked during the financial crisis a decade ago. Outside of my retirement savings, I’ve made automatic monthly investments in a total market index fund. And having cash in an online bank paying 1.9% helps me sleep at night.
