A broker charges €0 commission. Does that make day trading free? No. Even without explicit order fees, spreads, currency conversion and execution prices can cost money. A losing trade may be the largest financial impact of all.
Look beyond the platform’s headline price. This article calculates costs per completed trade, compares three trading patterns and explains the price gain needed to break even. All amounts are illustrative assumptions, not current fees of a particular broker.
Which costs do you pay when day trading?
A completed trade means both opening and closing a position. Total costs can include:
| Costs | What does it mean? | When does it apply? |
|---|---|---|
| Order commission | Fixed fee or percentage for buying and selling | Depends on the broker and market |
| Spread | Difference between bid and ask prices | When buying and selling immediately |
| Currency conversion | Cost of converting, for example, euros into dollars | When trading in another currency |
| Slippage | Difference between intended and actual execution prices | Especially in fast or thin markets |
| Market and platform fees | Possible exchange, data feed or subscription charges | Depends on the provider and plan |
| Financing charges | Cost of a borrowed position | Especially with margin or certain derivatives |
The AFM advises investors to consider all investment-service charges, including transaction costs. Providers must disclose relevant costs, but you also need to understand their impact at your trading frequency. AFM on investment costs and AFM on cost transparency.
1. Commission: count both directions
If an order costs €1.50, buying and later selling cost €3.00 together. Ten completed trades cost €30 even with no price gain or loss. Also check minimum charges, exchange-specific fees and real-time data costs.
2. Spread: the quiet cost of entry and exit
Suppose a share has a €49.98 bid and €50.02 ask. Buying 100 at the ask and immediately selling at the bid loses €4 without a market movement: 100 × €0.04. This creates a trading hurdle. Less liquid products or extended hours may have wider spreads. Investor.gov on spreads and extended-hours trading.
When doing your own calculation: actual purchase and sale prices already contain the spread. Do not deduct it a second time as a separate charge.
3. Currency costs: often important for US shares
A European investor using euros to trade dollar-priced shares may pay conversion fees. Frequency depends on the broker: some hold a dollar balance; others convert on each transaction. Check conversion rates and foreign-currency holding terms. EUR/USD movements also affect returns, but currency risk is not automatically a broker charge.
4. Slippage: the displayed price is not a promise
A market order may execute at a different price from the one you saw. Fast news, low liquidity or large orders can affect results. A limit order controls your maximum buying or minimum selling price but may remain unfilled. Execution quality therefore matters. Investor.gov on order execution.
5. Leverage and financing
Margin, CFDs and other leveraged products can create extra charges and larger losses. Financing is especially relevant for positions held longer, with product-specific terms. Leverage magnifies price movements relative to your capital. European CFD providers must apply relevant leverage limits and risk warnings, but that does not make CFDs suitable for every beginner.

What does one day trade cost? A worked example
You buy €2,000 of shares and close later the same day. Assume:
- €1.00 commission to buy and €1.00 to sell: €2.00.
- An effective spread of 0.10% of the trade value: €2.00.
- €1.00 worse execution on closing: €1.00.
- No currency conversion or other charges.
The estimated total trading hurdle is €5.00. The market must move roughly 0.25% in your favour to recover it: €5 ÷ €2,000 × 100. Only beyond that can there be a net trading gain under these assumptions.
A 0.50% rise represents €10 on €2,000. Subtract the estimated €5 in charges and execution disadvantage to leave €5 before any taxes. A 0.50% fall combines a €10 market loss with about €5 of trading friction: approximately €15 lost.
The spread here is an estimate relative to a reference price. For actual trades, use actual entry and exit prices and add only charges not already included.
Three scenarios: trading less can make a big difference
These examples show only trading costs, excluding market gains or losses, tax and subscriptions. Each month contains 20 days on which you actually trade.
| Scenario | Completed trades per day | Estimated cost per trade | Cost after 20 trading days | Gross profit needed to cover costs alone |
|---|---|---|---|---|
| Low activity | 1 | €3 | €60 | €60 |
| Active | 5 | €4 | €400 | €400 |
| Very active | 15 | €5 | €1,500 | €1,500 |
These are not account forecasts. They show the effect of frequency: five trades at €4 each per day cost €400 a month. A strategy making €300 gross that month would produce a €100 net loss under these assumptions, before tax and other fixed costs.
What does day trading with €500 or €1,000 cost?
Fixed fees weigh more heavily on small accounts. A €2 completed-trade charge on a €500 position requires a 0.40% gain merely to recover that €2, before spread, slippage and possible conversion fees.
On a €1,000 position, the same €2 is 0.20%. A bigger position is not automatically more attractive: it also increases potential cash losses. Increasing exposure to reduce relative fees does not fix a strategy without a demonstrated advantage.
How do you calculate your actual result after costs?
For a purchased position, use this formula:
Net trading result = sale proceeds − purchase amount − explicit buying and selling charges − any other costs.
Use actual amounts and currency rates on your statement. Execution prices usually already include spread and slippage; do not deduct these twice. Compare the net result with the time spent and risks taken.
For each trade, record date, product, position size, actual entry and exit prices, commissions, conversion fees, result and reason. After a sufficiently long series, calculate at least:
- total explicit costs;
- average cost per completed trade;
- net result after costs;
- largest daily loss and largest loss per trade;
- results compared with your predetermined rules.
Are zero-commission brokers free?
No. Zero commission only means one specific charge may be zero. Spread, currency conversion, execution quality and product charges still matter. Compare brokers for the product and market you will use, considering a full completed trade instead of a headline price.
The cheapest broker on paper is not automatically the best fit. Check authorisation, order types, execution, products and all charges. Read our broker comparison for European investors, Trading 212 review and Plus500 review. Always compare the specific product and account type.
The largest risk is not on the fee page
Trading losses are not broker fees, but can be day trading’s greatest financial consequence. A 2% loss on €2,000 is €40 before costs. Five such losses can significantly damage a small account. A stop-loss sets intended risk but does not guarantee the execution price.
Do not generalise product-specific statistics to all day trading. ESMA’s historical CFD research found that 74% to 89% of retail CFD accounts lost money. This concerns the accounts studied, not every share trader. It underlines the need to assess leverage carefully. Source: ESMA.
Frequently asked questions about costs
How much does day trading cost per month?
There is no fixed monthly amount. Multiply average completed-trade cost by your actual number of trades and add fixed fees separately. Five trades a day at €4 for 20 days cost an illustrative €400, excluding trading losses.
Do you pay to buy and sell?
Usually, if the broker charges per order. A completed trade has two orders. Even if both are commission-free, spread and other costs can remain.
Which costs more: commission or spread?
It depends on product, liquidity and broker. Fixed commission can weigh heavily on small liquid-share orders, while wide spreads may dominate less liquid products. Compare costs at your usual order size.
Are losses tax-deductible?
Tax rules vary by country, product and circumstances. No single reliable rule applies across Europe. Consult your local tax authority or a qualified adviser.
Can you day trade profitably with zero commission?
Possibly, but €0 commission proves nothing. The approach must remain profitable across a series after spread, execution, other charges and losses. A few winning trades are not evidence of that.
Conclusion: calculate the hurdle before placing an order
The true price combines explicit charges, trading friction and the risk of market losses. Calculate the gain needed to break even for each strategy. Check net results against real statements and treat leverage cautiously. For long-term wealth, also compare diversified low-cost investing.
