What Is a Pip, Lot Size and Spread? Forex Basics Explained Simply

Open any forex platform for the first time and you'll run into the same three words within minutes: pip, lot, spread. Most beginner guides define them in a single dense sentence and move on, which is exactly why so many new traders nod along without actually being able to do the math themselves. These three concepts aren't complicated — they're just rarely explained with real numbers attached, which is the only way they actually stick.

What a Pip Actually Is

A pip is the standard unit used to measure a price move in forex, and for most currency pairs it's the fourth decimal place — so if EUR/USD moves from 1.1050 to 1.1051, that's a one-pip move. Pairs that involve the Japanese yen are the exception: because yen pairs are quoted with only two decimal places, a pip there is the second decimal, not the fourth. It's a small distinction, but it trips up beginners who assume every pair works the same way. The pip itself doesn't tell you how much money moved — it only tells you how much the price moved. What that price move is worth in your account depends entirely on the next concept.

Lot Size: Where the Real Money Math Happens

A lot is simply the size of the position you're trading. A standard lot is 100,000 units of the base currency, a mini lot is 10,000, and a micro lot is 1,000. This is the number that turns a pip from an abstract price movement into an actual dollar figure. On a standard lot of most major pairs, one pip is worth roughly $10. Drop to a mini lot and that same pip is worth about $1. Drop again to a micro lot and it's about $0.10. Nothing about the market changed between those three examples — the pair moved the exact same distance each time. What changed is how much of that movement your position size allowed to reach your account balance, which is exactly why lot size, not leverage or luck, is the main lever most traders actually control.

Spread: The Cost You Pay Just to Enter

The spread is the gap between the price you can buy at (the ask) and the price you can sell at (the bid), and it exists on every single trade before the market has moved in your favour or against you at all. If EUR/USD shows a bid of 1.1050 and an ask of 1.1052, that two-pip gap is the spread — effectively the cost of entering the trade, paid to the broker rather than lost to the market. A tighter spread means a smaller head start the market needs to give you before a trade turns profitable; a wider one means the market has to move further in your favour before you're even at breakeven. This is also why spreads matter more to a scalper making dozens of trades a day than to a swing trader holding for a week — the cost is the same in pips, but it gets paid far more often.

Putting the Three Together With One Example

Say you open a 0.1 lot (mini lot) position on EUR/USD, and the spread is 1.5 pips. Before the market moves an inch in either direction, you're starting roughly $1.50 behind, because you'd need the price to move 1.5 pips in your favour just to break even. If the trade then moves 20 pips in your favour, at roughly $1 per pip on a mini lot, that's a $20 gain minus the $1.50 spread cost. None of that math is complicated once you see it laid out with numbers — it's only confusing when it's left as three separate definitions with nothing connecting them.

Why This Matters More Than It Seems

New traders often focus entirely on picking direction — will the price go up or down — and treat pips, lots and spread as background details the platform handles automatically. But your position size is what determines how much a losing trade actually costs you, and spread is a cost you pay on every single trade regardless of outcome, win or lose. Understanding these three terms isn't trivia; it's the arithmetic that sits underneath every risk decision you'll make from here on, including the position-sizing and stop-loss placement that come later.

These fundamentals are exactly where our Forex Trading Course starts — before charts, before strategy, before any talk of entries or setups — because trying to learn technical analysis without first understanding what a pip, lot and spread actually do to your account is like learning to read without knowing the alphabet. Get comfortable with the numbers first, and everything taught after them will make a lot more sense.
