What Should You Check on a Monthly Brokerage Account Statement?
A brokerage statement lands every month, and it’s tempting to file it away unread. A short, regular review of a few key sections is one of the simpler habits an investor can build.
The short answer
A monthly brokerage statement summarizes an account’s holdings, the transactions that occurred during the period, and any fees charged, and reviewing it regularly helps catch unauthorized activity, billing errors, or cost-basis mistakes before they compound over multiple statement cycles.
Holdings and balances
The holdings section lists what the account currently owns and its estimated value as of the statement date. Checking this against expectations — did a position that should be there still show up, and does the quantity match what was purchased — is the most basic level of review. Any unexplained addition or disappearance of a holding is worth investigating immediately rather than assuming it will sort itself out.
Transaction history
Every buy, sell, deposit, and withdrawal during the period should appear in the transaction section. This is the place to cross-check against any individual trade confirmations received earlier in the month, since the statement should reflect the same prices, quantities, and dates. A transaction that doesn’t match what was actually authorized is one of the clearer signs something needs attention.
Fees charged during the period
- Trading costs. Any commissions or per-trade charges tied to specific transactions.
- Account-level fees. Charges like a maintenance fee or an inactivity fee, which aren’t tied to a specific trade but to the account itself.
- Fund-level costs. These generally don’t appear as a line-item charge on the statement, since a fund’s expense ratio is deducted from the fund’s own returns rather than billed separately, but it’s worth remembering it’s a real cost sitting outside the statement’s fee section.
Comparing the fees charged against what the account agreement disclosed is a useful check, since a fee that appears without a clear match to the disclosed schedule is worth asking about directly.
Cost basis and gain/loss information
Many statements include a running cost-basis figure for each holding, along with an estimate of unrealized gain or loss. This figure matters most at tax time, since it feeds into how gains are eventually calculated when a position is sold. Verifying that the cost basis shown lines up with the actual purchase prices from trade confirmations is a good habit, particularly for positions built up gradually through multiple purchases over time.
Account activity that shouldn’t be there
- Unfamiliar trades. Any transaction that wasn’t authorized deserves immediate follow-up with the brokerage.
- Address or contact changes. A change nobody made can be an early sign of account compromise.
- Unexpected transfers. Money moving in or out that doesn’t match a known deposit or withdrawal.
A practical habit
Setting aside a few minutes each month to scan these sections, rather than only glancing at the total account value, turns the statement into an actual checkpoint instead of a formality. Over a year, this habit is what catches a billing mistake, a data-entry error, or unauthorized activity while it’s still a small, fixable issue rather than a larger dispute involving multiple statement cycles.
