Pips and Lots: How to Calculate Forex Profit and Loss

Pips and lots — the two ingredients of forex P&L

Forex profit and loss is simpler than it first looks. It comes down to:

P&L = pips moved × value per pip

The pip is the smallest standard price increment (the fourth decimal for most pairs, the second for yen pairs). → How to read a forex quote. The value per pip depends on your position size — the lot.

A lot is the standardized unit of trade size in forex:

Lot type	Units of base currency	Approx. pip value (USD pairs)
Standard lot	100,000	~$10 per pip
Mini lot	10,000	~$1 per pip
Micro lot	1,000	~$0.10 per pip

So on a EUR/USD trade, one standard lot moving 10 pips in your favor is roughly $100 (10 pips × $10). The same 10-pip move on a micro lot is about $1. The price move is identical — the size determines the money.

Worked example — putting it together

Suppose you buy 0.10 lots (one mini lot) of EUR/USD at 1.0850 and the price rises to 1.0870.

• Move: 1.0870 − 1.0850 = 20 pips
• Pip value at one mini lot: ~$1
• Profit: 20 × $1 = ~$20

Now the same trade at 1.0 lot (one standard lot): 20 pips × ~$10 = ~$200. And had the price instead fallen 20 pips, those same numbers become your loss. This symmetry is the heart of position sizing: bigger lots magnify both the gain and the loss of every pip.

⚠ Pip value for yen pairs is calculated differently because the pip sits at the second decimal — but the principle (pips moved × pip value) is identical.

How pips differ from futures tick value

If you’ve come from futures, pips and lots play the same role as ticks and tick value, but the units differ. Futures measure movement in ticks, each with a fixed dollar value set by the contract; forex measures movement in pips, with the value flowing from your lot size. → Ticks and tick value and CFD vs futures.

The practical upshot is the same: in both cases you need to know what one unit of movement is worth before you can size a trade or set a stop responsibly.

Position sizing from your loss limit

This is where pips and lots become a risk tool, not just arithmetic. The professional approach works backward from your loss limit:

1. Decide your per-trade loss limit — say, 1–2% of your account. → Leverage and risk management.
2. Set your stop distance in pips based on the chart.
3. Choose a lot size so that stop pips × pip value ≤ your loss limit.

For example, if your loss limit is $50 and your stop is 25 pips away, then a pip value of $2 (about 0.20 lots) risks exactly $50 — so that’s your size. The stop and the limit decide the lot, not the other way around.

Confirm your pip value before you trust it

The figures in the table above are close enough to reason with, but the exact value depends on the pair and the quote currency — so check it rather than assume it. Merini’s free web demo lets you size an order on EURUSD and then on USDJPY and compare what one pip is actually worth in each; the yen pair, with its pip at the second decimal, is the one people most often carry the wrong number into. Then run the backward calculation for real: fix a loss limit, measure your stop in pips, and let the lot size fall out of it rather than the other way round → Check your pip value live

Frequently asked questions

What’s the difference between a lot and leverage?

The lot is how big your position is; leverage is how little margin you post to control it. A bigger lot means more pip value at risk; leverage determines how much of your own capital sits behind that lot. They interact, but they’re different dials.

Can I trade smaller than a micro lot?

Some platforms offer fractional or nano sizing, but micro lots (1,000 units, ~$0.10/pip) are already small enough for most beginners to practice with manageable risk. Smaller size lowers the money at stake but doesn’t remove leverage risk.

How do I know my exact pip value?

For USD-quoted pairs the figures above are close approximations. The precise value depends on the pair and the quote currency, and most platforms display it for you. Practicing on a demo is a good way to see pip value move in real time before risking real money.
