For a college student investing $50 per month, Fidelity Investments and Robinhood are the best choices because they feature $0 account minimums, $0 trading commissions, and fractional shares that ensure your entire monthly contribution goes directly into the market rather than being eaten up by monthly subscription fees.
Traditional micro-investing apps like Acorns or Stash charge flat monthly subscription fees (such as $3 to $12 a month). If you only invest $50 a month, a $3 monthly fee amounts to a massive 6% drag on your investment capital right off the bat.
Fidelity Investments: Best for long-term growth and education. It allows fractional share trading (Fidelity Stocks by the Slice) starting at $1, meaning your $50/month can buy pieces of major ETFs or blue-chip stocks. It has zero account minimums and zero trading commissions, plus robust research tools if you want to learn.
Robinhood: Best for a streamlined mobile experience. It popularized commission-free trading, supports fractional shares starting at $1, and has an exceptionally clean interface for beginners.
Charles Schwab: Great alternative option. Through Schwab Stock Slices, you can buy fractional shares of S&P 500 companies with as little as $5, backed by top-tier customer service and zero commission fees.
Instead of trying to pick individual stocks—which carries high risk with a small capital base—look into buying a low-cost, broad-market index fund or an Exchange-Traded Fund (ETF) like an S&P 500 index fund (e.g., FXAIX or VOO). Setting up an automatic recurring transfer of $50 each month helps build a disciplined investing habit without extra friction.
If you'd like, let me know:
Do you prefer a hands-off approach (automated index investing) or want to pick your own stocks/ETFs?
Are you also interested in opening a tax-advantaged retirement account like a Roth IRA?
For a college student starting with $50 per month, I’d generally recommend Fidelity or Schwab for low-cost investing, rather than paying a monthly subscription for a micro-investing app. You can start small, invest in diversified funds, and avoid letting fees eat into your early returns.
The key is finding a platform with no account fees, no required minimum balance, and investments you can actually buy with $50. A $3 monthly fee, for example, would consume 6% of your entire monthly contribution before your investments have a chance to grow.
Best investing apps for $50/month
1. Fidelity (Best overall)
Cost: $0 account fee · $0 online U.S. stock and ETF commissions
Fidelity lets you buy fractional shares of eligible stocks and ETFs starting at $1, set up recurring investments, and choose your own diversified funds. Great for learning long-term investing without paying for an app subscription.
A solid alternative if you want a traditional brokerage with research tools and educational resources. Its Stock Slices feature lets you buy fractional shares of eligible S&P 500 companies with as little as $5.
Cost: $0 commission on eligible stock and ETF trades
An easy-to-use mobile option with fractional shares starting at $1 and automatic recurring investments. It can be convenient, though its trading-focused interface may tempt beginners to trade individual stocks too frequently.
Best suited to people who want a managed portfolio and spare-change investing with minimal involvement. But at $50 a month, the subscription is expensive relative to your contributions.

How I would start with $50 per month
1. Open a Fidelity account
Choose a regular brokerage account if you want flexibility to access the money before retirement, or consider a Roth IRA if you have eligible earned income and are investing for retirement.
2. Start with a diversified, low-cost index fund
Consider a broad U.S. stock-market index ETF rather than trying to guess which individual company will perform best. Compare expense ratios and make sure the fund is eligible for fractional purchases.
3. Automate your $50 contribution
Schedule it monthly, keep adding consistently, and avoid investing money you will need for tuition, rent, or other near-term expenses.
Stock-market investments can lose value, especially over short periods. If you lack emergency savings or have expensive credit-card debt, address those priorities before committing money to the market.
