How pip value is calculated for USD/CHF
USD/CHF is quoted in CHF, so one pip on a standard lot is worth 0.0001 × 100,000 = 10 CHF. To turn that into US dollars, divide by the USD/CHF rate itself: at 0.8900 that is $11.24. The USD pip value therefore moves with the price: it falls when USD/CHF rises and rises when it falls.
Worked example
Holding 1 standard lot of USD/CHF: Assumes USD/CHF at 0.8900, an example rate.
0.0001 × 100,000 ÷ 0.8900 = $11.24
One pip is worth $11.24. A 30-pip move is worth $337.08 on one lot, $33.71 on a mini lot and $3.37 on a micro lot.
These are the calculator's default inputs above, so its result matches.
