What Is a Pip Calculator

A pip calculator, in five lines

A pip calculator is a small tool that says what one pip is worth in your account's money, where a pip is the fourth decimal place of the price. The pair, the lot size and the account currency go in, where a lot is 100,000 units of the currency; the money one pip moves the trade by comes out, and any move is that number times the pips. The plain case is the euro in a dollar account: one pip at one lot is 10 dollars, always. The euro rose 16.9 pips between 10:00 and 18:00 on Tuesday 25 August 2026, which is 1.69 dollars at 0.01 lot, 16.90 at 0.10 and 169 at 1.00.

A slide rule

Picture a slide rule. The fixed upper scale is pips; the sliding lower scale is dollars, and it is slid once to the lot size, here 0.10 lot where a pip is one dollar, so the two scales line up one to one. After that every pip distance has its dollar figure straight under it, read through the cursor. A pip calculator is that rule: the size is set once, and any move on the chart reads off as money without a fresh sum each time.
