GER40 lot size calculator
A standard GER40 lot is 1 contract, quoted to 2 decimals, and one point of 1 moves 1 EUR per lot. Feed the calculator your account size, the percentage you are willing to lose and the distance to your stop, and it returns the size that puts exactly that much at risk — rounded down to your broker's lot step so the real risk never comes out above the target.
What makes GER40 different
The DAX quotes in euros, so a dollar account has to convert every result at the EURUSD rate — a step that silently shifts the size by several percent when the euro moves. It is also one of the most volatile major indices per point, and it reacts to the European open rather than the American one, so stops sized from US-session behaviour tend to be too tight.

Values in EUR, the currency GER40 is quoted in. A point here is 1.
| Lot size | Units | Value of 1 point |
|---|---|---|
| Standard (1.00) | 1 | 1 EUR |
| Mini (0.10) | 0.1 | 0.1 EUR |
| Micro (0.01) | 0.01 | 0.01 EUR |
A worked example
- Risk in money: a 10 000 EUR account risking 1% puts 100 EUR on the line.
- Stop distance in price: 100 points × 1 = 100.
- Loss per lot: 100 × 1 = 100 EUR.
- Lot size: 100 ÷ 100 = 1, rounded down to 1.
The example assumes an account in EUR. If yours is in another currency, every figure above gets multiplied by the rate from EUR to your currency, which the calculator applies automatically.

| 0.5 % | 1 | 0.5 | 0.25 | 0.12 |
| 1 % | 2 | 1 | 0.5 | 0.25 |

Frequently asked questions
How much is one point worth on GER40?
On a standard lot of 1 contract, one point of 1 is worth 1 EUR. A mini lot is a tenth of that and a micro lot a hundredth. If your account is not in EUR, multiply by the current rate from EUR to your account currency.
What lot size should I use on GER40?
There is no single right size: it depends on how much you are willing to lose and where your stop sits. Decide the loss first — most traders cap it at 1% to 2% of the account per trade — then divide that amount by the loss per lot at your stop distance. The calculator above does exactly that and rounds down to your broker's step.
Why does my broker show a different GER40 lot size?
Almost always because the contract or the point definition differs. Open your platform's contract specification for GER40, compare the contract size against 1 and the tick against 1, and correct them under "broker settings" above. The second cause is the conversion rate when your account currency is not EUR; you can override that too.
What contract size does GER40 use?
This page assumes 1 EUR per point per lot, which is the most common setup, but it is not universal — $5, $10 and $25 contracts all exist. Check yours once in the contract specification and save it as a template; getting this wrong scales every size you calculate by the same factor.
I have a dollar account — does that change the GER40 calculation?
Yes. GER40 settles in EUR, so the loss per lot has to be converted from EUR into dollars at the current rate. The calculator does it automatically and tells you which rate it used, and you can type your broker's own rate if you want the figure to match your platform to the cent.
