Browse Investing by type

Investing has gotten meaningfully more accessible over the past decade — commission-free trading is now standard, minimums have mostly disappeared, and it's possible to build a diversified portfolio with a handful of low-cost index funds and very little ongoing effort. That accessibility is genuinely good, but it also means the differentiators between platforms have shifted to things that are less obvious at a glance.

The decision most people actually need help with isn't which stock to pick — it's structural: which account type to use (taxable, IRA, Roth IRA), which platform to hold it at, and whether to manage it yourself or hand it to a robo-advisor for a small annual fee. Getting these structural decisions right tends to matter more, over the long run, than any individual investment choice.

We also spend time here on fund fees specifically, because a seemingly tiny difference in expense ratio compounds significantly over decades — a fund charging 0.8% versus one charging 0.05% can mean a meaningfully different balance by retirement, even holding identical underlying assets.

Tax treatment is another area that quietly matters more than picking the "right" fund. Where you hold an investment — a Roth IRA versus a taxable brokerage account, for instance — can change your after-tax outcome significantly, independent of how the investment itself performs. We try to cover account selection with the same seriousness usually reserved for fund selection, since it's often the bigger lever.

What to know before you compare

  • Commission-free trading is nearly universal now — don't let that be the deciding factor between platforms.
  • Confirm a platform supports the account types you need: traditional IRA, Roth IRA, taxable brokerage, or rollover accounts.
  • A robo-advisor's fee is worth paying only if it replaces real, consistent work — rebalancing, tax-loss harvesting, staying invested.
  • Expense ratios vary by fund, not just by broker — compare the specific funds you'd actually hold, not just the platform.
  • Be honest about whether you'll actually rebalance a DIY portfolio on schedule, or whether it'll just sit unbalanced for years.

The guides below cover choosing a brokerage, deciding between robo-advisors and DIY investing, and other structural decisions worth getting right early.

Frequently asked

Should I use a robo-advisor or manage my own portfolio?

It depends on whether you'll actually maintain a DIY portfolio consistently. A robo-advisor's small fee buys automatic rebalancing and behavioral discipline — genuinely valuable if you'd otherwise let a self-managed portfolio drift or panic-sell during downturns.

How much do I need to start investing?

Most major platforms now have no minimum, and fractional shares let you invest small amounts into expensive funds or stocks. Starting consistently with a small amount tends to matter more than waiting to start with a larger one.
