What is a Pip, Lot, and Spread in Forex?
These three terms come up constantly in forex, and understanding them is essential before you calculate position size or read a price quote confidently.
What is a pip?
A pip ("percentage in point") is the standard unit used to measure price movement in forex. For most pairs, it's the fourth decimal place — so if EUR/USD moves from 1.1000 to 1.1010, that's a 10 pip move. For pairs involving the Japanese Yen, a pip is the second decimal place instead (e.g. USD/JPY moving from 150.00 to 150.10 is also a 10 pip move).
What is a lot?
A lot is the standardized size of a forex trade — it defines how many units of currency you're actually trading:
- Standard lot — 100,000 units of the base currency
- Mini lot — 10,000 units (0.1 standard lot)
- Micro lot — 1,000 units (0.01 standard lot)
Lot size directly determines how much money each pip movement is worth. On a standard lot of a USD-quoted pair, one pip is typically worth about $10; on a mini lot, about $1; on a micro lot, about $0.10. You can calculate this precisely for your exact trade using DeskTerminal's Trade Calculator.
What is a spread?
The spread is the small difference between the price at which you can buy (the "ask") and the price at which you can sell (the "bid") a currency pair at any given moment. This gap is effectively the broker's built-in cost of executing your trade — it's not a separate fee you pay directly, but it does mean a trade needs to move slightly in your favor just to break even.
Major pairs like EUR/USD typically have very tight spreads (often under 1-2 pips with a good broker), while exotic pairs can have spreads of 20+ pips.
Putting it together
Say you trade 1 standard lot of EUR/USD, and the spread is 1 pip. That 1 pip costs you roughly $10 the moment you open the trade — the price needs to move at least 1 pip in your favor before you're at breakeven. Understanding pips, lots, and spread together is what lets you actually calculate real trading costs and potential profit/loss before you place a trade.

Putting the Numbers Together in One Example
Say you open a 0.5 mini lot (5,000 units) position on EUR/USD at 1.1000, with a 20 pip stop-loss and a 40 pip take-profit — a 1:2 risk-reward ratio.
On this position size, each pip is worth approximately $0.50. If your stop-loss is hit, you lose 20 pips × $0.50 = $10. If your take-profit is hit instead, you gain 40 pips × $0.50 = $20. If the spread on this pair is 1 pip, that first pip of movement doesn't count toward your profit — it just gets you to breakeven — so your effective risk-reward is closer to 19:41, still a solid setup, but a useful reminder that spread quietly reduces every trade's real numbers, and should factor into how tight a stop-loss you're comfortable using.
Frequently Asked Questions
What exactly is a pip in forex?
A pip is the standard unit of price movement, usually the fourth decimal place for most pairs (or second decimal for Yen pairs) — e.g. EUR/USD moving from 1.1000 to 1.1010 is a 10 pip move.
How much money is one pip actually worth?
It depends on your position size — on a standard lot (100,000 units) of a USD-quoted pair, one pip is typically worth about $10; on a micro lot, about $0.10.
What's the difference between a lot and a pip?
A pip measures price movement; a lot measures position size (how much currency you're trading). Together they determine how much money each price movement is worth to you.
Why does the spread matter when I'm not paying a separate fee?
The spread is a built-in cost — the price needs to move in your favor by at least the spread amount before your trade reaches breakeven, so wider spreads directly reduce your net profit potential.
