You open your broker account and see one portfolio value. Then you open a portfolio tracker and see another. The difference may be only a few euros, or it may be large enough to make you question whether the imported data is accurate.
In many cases, both values are reasonable. They may simply be answering slightly different questions. A broker usually focuses on what the account is worth right now. A portfolio tracker may calculate value from imported transactions, market prices, currency rates and its own handling of cash, fees and income.
Two Correct Portfolio Values Can Still Be Different
A portfolio value is not always a single universal number. It is the result of several inputs that can be updated at different times and interpreted in different ways.
Ask which prices, exchange rates, cash balances and transaction rules were used to produce each number.
Why Your Portfolio Tracker and Broker May Not Match
Different Market Prices
Your broker and tracker may use different data providers or update at different intervals. One may show a live quote while the other uses the latest available delayed or closing price.
Different Exchange Rates
Foreign holdings must be converted into your portfolio currency. Even a small difference in the exchange rate can create a visible gap in a large multi-currency portfolio.
Cash Is Included Differently
A broker may include all account cash in the headline total. A tracker may include only imported cash transactions, exclude cash completely or place it in a separate section.
Fees Are Missing
Trading commissions, custody charges, conversion costs and other fees reduce real portfolio value. Missing even small recurring charges can make the historical record drift over time.
Dividends Are Not Fully Recorded
The tracker may have a gross dividend while the broker balance reflects the net amount after withholding tax. A dividend can also appear in cash before it has been imported into the tracker.
Transactions Are Still Processing
A purchase, sale, dividend or deposit may appear in one system before it is fully reflected in the other. Timing depends on the transaction type, market and import method.
Corporate Actions Were Handled Differently
Stock splits, mergers, spin-offs and symbol changes can alter share counts and cost basis. If one platform processes the event automatically and the other does not, totals may diverge sharply.
A Transaction Is Missing or Duplicated
Duplicate imports and missing trades affect holdings, cost basis, cash and performance calculations at the same time.
What Different Types of Mismatches Usually Look Like
The size and behaviour of the difference often provide a clue about its source.
| What you notice | Likely cause | What to check first |
|---|---|---|
| The value changes during the day | Quote timing or delayed market data | Compare the price and timestamp for the largest holding |
| The difference moves with currency markets | Different FX rates or conversion timing | Compare the base currency and exchange rate used |
| The gap equals the account cash balance | Cash is excluded or recorded separately | Check whether deposits, withdrawals and idle cash were imported |
| The gap appeared after a recent trade | Pending or missing transaction | Check trade date, quantity, price, fees and status |
| The share count is wrong | Missing trade or corporate action | Compare the full transaction history for that security |
| The total is close but performance is different | Cash flows, fees or return methodology | Separate deposits from investment gains |
| The difference grows slowly over time | Missing fees, dividends or recurring transactions | Audit income and account charges month by month |
How to Find the Source of the Difference
Do not start by reviewing every transaction. Begin with current holdings and work backwards.
Confirm the comparison time
Refresh both systems and check whether totals are based on current, delayed or previous closing prices.
Compare the number of shares
Start with your largest positions. If quantities match, the issue is more likely to involve prices, currencies or cash.
Compare individual market prices
Check whether both platforms use the same exchange, instrument and quote currency.
Review the portfolio currency
Confirm that both totals are displayed in the same base currency and note the exchange rate applied to foreign assets.
Reconcile cash and recent activity
Review recent deposits, withdrawals, dividends, fees, purchases and sales.
Inspect corporate actions and duplicates
Check for stock splits, symbol changes, repeated imports or transactions that were never added.
Reconcile quantities first, prices second, currencies third and cash flows last. This order eliminates most portfolio mismatches efficiently.
When Should You Be Concerned?
A small temporary difference is often normal. A persistent or unexplained mismatch deserves closer attention, especially when it affects the number of shares you own.
Two systems can show nearly identical current values while reporting different returns because return calculations depend on deposits, withdrawals, dividends, fees and timing.
How to Prevent Future Mismatches
Most long-term data problems begin as small inconsistencies that are left unresolved.
Import Regularly
Update your portfolio while trades, deposits and dividends are still easy to remember and verify.
Review Before Saving
Check imported quantities, symbols, currencies and fees before new transactions become part of your permanent history.
Reconcile Monthly
Compare holdings and cash against the broker occasionally. Small problems are easier to correct than multi-year discrepancies.
Preserve Source Documents
Keep trade confirmations and broker statements as the reference when imported data needs to be audited later.
Frequently Asked Questions
Is it normal for a portfolio tracker to show a slightly different value?
Yes. Small differences can result from quote delays, exchange rates, rounding and the treatment of cash. The important point is whether holdings and transaction history are accurate.
Which value should I trust?
Your broker statement is the primary record for assets held in that account. A tracker is most useful as a consolidated analytical record, especially across multiple brokers or currencies.
Why does the value match but the return does not?
Current value is a snapshot. Return depends on purchase prices, deposits, withdrawals, fees, dividends and timing.
Can exchange rates create a large difference?
Yes. The effect becomes more visible when a large part of the portfolio is denominated in foreign currencies.
How often should I reconcile my portfolio?
Check after major imports, corporate actions and large transactions. A regular monthly or quarterly review can prevent small inconsistencies from accumulating.
A Difference Does Not Automatically Mean an Error
Portfolio values can differ because systems use different prices, exchange rates, cash rules and update times. These variations are often harmless when share quantities and transaction records remain correct.
The most reliable method is to compare the portfolio layer by layer: holdings, prices, currencies, cash and recent transactions.
