USDCHF lot size calculator
A standard USDCHF lot is 100,000 units, quoted to 5 decimals, and one pip of 0.0001 moves 10 CHF 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 USDCHF different
Majors are the most liquid pairs on the market, with the tightest spreads and the most predictable pip values. When the pair quotes in your account currency the pip value is fixed; when it does not, it drifts with the exchange rate and the calculator converts it for you.

USDCHF pip value by lot size
Values in CHF, the currency USDCHF is quoted in. A pip here is 0.0001.
| Lot size | Units | Value of 1 pip |
|---|---|---|
| Standard (1.00) | 100,000 | 10 CHF |
| Mini (0.10) | 10,000 | 1 CHF |
| Micro (0.01) | 1,000 | 0.1 CHF |
A worked example
- Risk in money: a 10 000 CHF account risking 1% puts 100 CHF on the line.
- Stop distance in price: 20 pips × 0.0001 = 0.002.
- Loss per lot: 0.002 × 100,000 = 200 CHF.
- Lot size: 100 ÷ 200 = 0.5, rounded down to 0.5.
The example assumes an account in CHF. If yours is in another currency, every figure above gets multiplied by the rate from CHF to your currency, which the calculator applies automatically.

| Risk | 10 pips | 20 pips | 40 pips | 80 pips |
|---|---|---|---|---|
| 0.5 % | 0.5 | 0.25 | 0.12 | 0.06 |
| 1 % | 1 | 0.5 | 0.25 | 0.12 |
| 2 % | 2 | 1 | 0.5 | 0.25 |

Frequently asked questions
How much is one pip worth on USDCHF?
On a standard lot of 100,000 units, one pip of 0.0001 is worth 10 CHF. A mini lot is a tenth of that and a micro lot a hundredth. If your account is not in CHF, multiply by the current rate from CHF to your account currency.
What lot size should I use on USDCHF?
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 USDCHF lot size?
Almost always because the contract or the pip definition differs. Open your platform's contract specification for USDCHF, compare the contract size against 100,000 and the tick against 0.0001, and correct them under "broker settings" above. The second cause is the conversion rate when your account currency is not CHF; you can override that too.
I have a dollar account — does that change the USDCHF calculation?
Yes. USDCHF settles in CHF, so the loss per lot has to be converted from CHF 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.
