The return you see on the chart is not the return that ends up in your account. Two items stand between the market and your wallet: fees and taxes. The first of these is one of the few things in investing you fully control - which is why it pays to understand it before you send your first money.
Why small percentages matter so much
A fee of 2% a year sounds harmless. But fees work just like compound interest, only in reverse: every year they bite a piece out of the entire value of your investment, including the returns from previous years. What looks like a trifle turns, over twenty or thirty years, into an amount that is hard to believe. Low costs are the most reliable edge a beginning investor can acquire - they require no market forecasting, just attention when choosing.
TER: the price tag of a fund or ETF
With funds and ETFs the total annual cost hides behind the abbreviation TER (total expense ratio). It is a percentage of the value of your investment that the fund manager takes each year for their work - managing the portfolio, administration and operations. A TER of 0.2% means that out of every CZK 10,000 you pay CZK 20 a year; a TER of 2% means CZK 200.
An important detail: you never pay the TER through an invoice. It is deducted continuously and automatically from the fund's value, so you will never see it as a line item on a statement. That is exactly why it is so easy to overlook - and exactly why you should always look it up in the fund's documents before buying. As a general rule, passive index funds and ETFs tend to have a markedly lower TER than actively managed funds, because they pay nobody for picking stocks.
Transaction fees and currency conversions
The second layer of costs arises when trading. A transaction fee is the amount a broker charges for executing a buy or a sell - a fixed amount at some brokers, a percentage of the volume at others, zero at some (those then earn their money elsewhere, for instance on exchange rates). On its own it tends not to be large, but it multiplies with frequency: whoever trades every week pays many times more in fees than an investor buying once a month.
Transaction costs also include the spread - the difference between the price at which you can buy at a given moment and the price at which you can sell. For large, heavily traded stocks and ETFs it is negligible; for small, thinly traded names it can be surprisingly wide. It is not a fee on any invoice, but you pay it on every trade just as reliably.
Less conspicuous still is currency conversion. If you buy an American stock with Czech crowns, someone has to exchange the crowns for dollars - and the broker typically charges a markup on the exchange rate, often tenths of a percent of the amount. It is paid on the purchase and on the sale, and with dividends in a foreign currency easily on every payout as well. For a long-term investor it is a smaller item than the TER, but with frequent trading across currencies it can add up.
A worked example: 0.2% vs. 2% a year
Let us show the impact on a hypothetical example. To stress upfront: this is a model calculation with an invented, in no way guaranteed return - it serves only to compare the effect of costs, not as a promise of what an investment will earn.
Imagine a one-time investment of CZK 100,000 for 30 years with a hypothetical gross return of 7% a year. The only thing that differs between the two variants is the annual cost:
- Costs of 0.2% a year: a net return of 6.8% a year. After 30 years the investment is worth roughly CZK 720,000.
- Costs of 2% a year: a net return of 5% a year. After 30 years the investment is worth roughly CZK 432,000.
The difference comes to almost CZK 290,000 - nearly three times the original investment - and it did not arise from better stock picking or luckier timing. It arose solely because one variant pays 1.8 percentage points more each year. The more expensive fund would have to beat the market by that margin every single year just to keep pace with the cheaper one - and over the long run only very few managers pull that off.
Taxes: a general framework, not a manual
The second item between the market and your wallet is taxes. Here let us be careful: tax rules differ by the country where you are a tax resident, and Bulios operates in six markets with six different systems. No specific rate or deadline from one market automatically applies elsewhere - and this article is not tax advice.
The general framework, however, is similar everywhere and worth knowing. Two situations typically come up:
- Taxation of dividends - a paid dividend is taxable income in most countries. With foreign stocks, withholding tax in the company's country and international double-taxation treaties often come into play as well.
- Taxation of sales - profit from selling securities is usually subject to tax, though many countries offer exemptions once conditions are met, for instance after a certain holding period or up to a certain volume.
The practical takeaway for a beginner: before your first investment, check the rules of your own country - on the website of the local tax authority, with your broker, or with a tax advisor. Long-term holding also usually simplifies the tax question: whoever buys and holds rarely deals with the taxation of sales, while a frequent trader deals with it constantly.
What to take away
You cannot influence the market, but you can influence fees. Before buying a fund or ETF, look up its TER; go through your broker's price list for transactions and currency conversions; and trade less often rather than more. Low-cost behavior shows nothing after a month, but after twenty years it becomes one of the largest items in the entire result. How fees fit into the overall plan is shown by the rest of the basics track of the Bulios academy.
