One investment, three different returns

Say you put $10,000 into an S&P 500 index fund on 3 January 2023. Here is what it was worth on 16 September 2026, measured in three currencies.

Measured inPut inWorth on 16 September 2026Return
US dollars$10,000$19,807+98%
Euros€9,365€17,168+83%
Turkish lira₺187,433₺963,732+414%

Price change of an S&P 500 index fund (VOO) between its closing prices on 3 January 2023 and 16 September 2026, dividends not included. Each amount uses the exchange rate of its own day: 0.9365 and 0.8667 euros per dollar, 18.74 and 48.66 lira per dollar.

All three are true. The fund did exactly the same thing in every row. What changed is the currency. The dollar weakened against the euro, so someone counting in euros made less. The lira fell from 18.74 to 48.66 per dollar, so most of the lira gain came from the lira losing value, not from the fund. That is why people who earn in a high-inflation currency often check their results in dollars or euros too.

Investing in lira at home instead? StockFly can put your own portfolio next to an index such as the S&P 500 over the same period, measured in lira or in dollars, so you can see which did better.

How StockFly keeps the numbers right

  • More than 160 currencies

    Pick a currency and the whole portfolio switches: value, cost, gains, dividends and charts. Switch back in one click.

  • Each trade at its own day's rate

    Every buy, sell and dividend is converted at the exchange rate of the day it happened, so your cost is what you actually paid.

  • Rates you can check

    The transactions page shows the exact rate used for every trade, so any figure can be checked by hand.

  • Nothing guessed

    If a rate is missing for a day, the figure stays blank with a note. It is never estimated.

  • The market in your currency too

    Compare your return with an index such as the S&P 500, with both measured in the currency you picked.

Who it is for

  • You earn in one currency and invest in another, for example earning lira or euros and buying US funds.
  • You live with high inflation and want to see your results in dollars or euros as well.
  • You hold shares on more than one stock market, each in its own currency.

Questions, answered

Which currencies can I see my portfolio in?
More than 160 world currencies. Pick one and the whole portfolio switches to it: value, cost, gains, dividends and charts. You can switch again at any time.
Does it use today's exchange rate or the rate on the day I bought?
The rate on the day you bought. Every buy, sell and dividend is converted at the exchange rate of its own day, and only today's value uses today's rate. Converting everything at today's rate would hide the currency effect completely.
Can one portfolio hold stocks in different currencies?
Yes. Each holding keeps its own currency, for example a US fund in dollars and a Turkish stock in lira, and the totals are shown in the currency you pick.
How can I see whether dollars would have done better?
Switch your portfolio to dollars to see what it made in dollar terms. The You vs the Market report then compares your return with an index such as the S&P 500 over the same period, with both measured in the currency you picked.
Does StockFly connect to my broker or bank?
No, and it never asks for your login details. Upload a trade file or statement from your broker, or add your trades by hand.
Is the tax summary in my currency too?
Yes, on Pro. The year's realized gains and dividends are worked out lot by lot at each trade's own exchange rate, in the currency you choose or in each holding's own currency, and download as PDF or Excel.
What does it cost?
The free plan includes every currency, the trade-day exchange rates, the You vs the Market report and unlimited holdings. Pro adds more portfolios, every performance report, the planner tools, stock insights and the tax summary, for $4.99 a month or $49 a year. Every new account starts with 30 days of Pro, no credit card.
