Whether your student loans are being forgiven, you received a gift or earned some extra cash this month, using $100 or less to start your investment journey is possible now more than ever.

Thanks to investment products like fractional shares and exchange-traded funds, or ETFs, you can enter the market for dollars and cents — and quickly build a diverse portfolio with little money. Not to mention the apps that can help you save or invest spare change.

So if that extra Benjamin lands in your lap, here’s what you need to know about how to start investing, the financial products that can help you diversify your portfolio for less, and how to make your money work the hardest for you.

What to consider before you begin

Before you begin investing, be sure you’ve taken care of more immediate financial needs like paying off high-interest debt and building up an emergency or rainy day fund, says Jen Hemphill, an accredited financial counselor in Fairfax, Virginia.

If you’ve got that covered, it can feel nerve-wracking to consider beginning to put cash in an investment account instead of your savings account. One strategy for overcoming fears about investing is to focus on your goals, according to Hemphill, who also works with clients and provides free bilingual financial education on her podcast "Her Dinero Matters."

Hemphill suggests you first consider why you are investing. Whether your reason is college, a home, retirement, a medical procedure, a trip or something else, why you want to invest affects what type of financial product is the best match for your timeline and goals.

Why you want to invest also informs how much risk you're willing to take. Investments always involve risk, says Hemphill. It's normal for markets to go up and down, and you need to understand that before you start investing. If you need the money for something in the next five years, for example, a high-yield savings account might be a better option because even though your money has less growth potential, there's less risk involved.

But if you have a very long investment timeline, you could take on more risk, with the thought that it will pay off eventually.

"When the market is down,” Hemphill says, “you have to be able to just press on.”

How to start investing with little money

Some beginners might feel confused or stuck on what exactly to invest in and how.

“The hardest part for beginners is to actually start to put the money in the account and click buy,” says Orlando, Florida-based certified financial planner Maggie Gomez. Gomez’s experience of financial insecurity and homelessness early in life informed how she approaches making financial education and services accessible to a more diverse range of people.

If you share that uncertainty about how to begin, here are four ways to start investing.

1. Retirement plans for retirement goals

If your investing goal is retirement, you might already be invested if you’re taking part in an employer-sponsored 401(k) plan.

If you’re not and want to start saving for retirement, you can set up a tax-advantaged plan on your own with an individual retirement account, or IRA. Since some providers do require account minimums for IRAs, be sure to look for a provider with a low or $0 minimum.

Roth IRAs are tax-advantaged accounts for long-term investors who want to contribute after-tax dollars and withdraw their investment tax-free in retirement. Traditional IRAs, on the other hand, allow you to invest pretax dollars. With this type of account, you pay income taxes upon withdrawing the money in retirement.

2. Low-cost brokerage accounts for (nonretirement) financial goals

If you have a different investment goal, a brokerage account may be right for you. Brokerage accounts allow you to invest in things like stocks, ETFs and index funds. They’re easy to open and differ from retirement accounts in that you can sell at any time and withdraw your funds without penalty. However, note that you'll still likely have to pay capital gains taxes if you make money on your investments.

If you’re opening a new account, be sure to look for a brokerage that offers commission-free trades, no account minimum and no fee to open the account.

You can look for a brokerage that offers fractional shares, which let you buy portions of a single share of a company’s stock, rather than a whole share. So if you only have $20 to contribute to a stock that’s priced at $50, fractional shares can get you there.

3. Index funds and ETFs

Buying and selling individual stocks generally carries a high level of risk. You could instead invest in ETFs and index funds, which are baskets of investments that include dozens, hundreds or even thousands of stocks. These products can track various assets, like stocks, bonds, currencies and commodities, or even an entire market.

In buying a share of an index fund or ETF, you’re instantly gaining access to shares of a wide range of companies, offering easy and quick portfolio diversification, which makes them an excellent choice for beginners. However, note that while index funds and ETFs are similar in many ways, they have their differences.

Once you’ve selected an account, consider whether you want to invest all at once or over time. The $100 you have could be your first contribution, or you could break it up into smaller contributions such as $20 a month.

Spreading out your purchases over time like this is a financial strategy called dollar-cost averaging. Micro-investing apps also dollar-cost average by rounding up purchases to a debit card and investing tiny amounts into ETFs.

4. Help from robo-advisors

A robo-advisor is an automated investing service that makes portfolio recommendations after assessing your risk tolerance, investment preferences and time horizon through a questionnaire. The recommended portfolios are often composed of ETFs and range from more conservative to aggressive investment options. Once you choose a portfolio, the robo-advisor does the investing for you.

While some robo-advisors charge portfolio management fees around 0.25%, others charge no management fee at all. You'll want to look for robo-advisors with low or zero account minimums.

There's a lot to consider as you begin your investing journey, but the important part, says Hemphill, is to just “start where you’re at.”
