Pips, Lots and Leverage Explained: Forex Maths That Matters

Ask a room of new traders what one pip of EUR/USD is worth on their open position and most will guess. That guess is the whole problem: every risk decision in forex, from stop distance to lot size to surviving a drawdown limit, reduces to knowing exactly what a pip pays and what a lot costs. The mechanics take ten minutes to learn properly and most people never do.

What a pip actually is

A pip is the standard increment of a currency quote. For most pairs it is the fourth decimal place: EUR/USD moving from 1.1000 to 1.1001 has moved one pip. For yen pairs it is the second decimal: USD/JPY moving from 150.00 to 150.01 is one pip.

Most platforms quote one digit finer than the pip. That extra digit is a pipette, one tenth of a pip, and it exists so spreads can be priced precisely. A quote of 1.10004 reads as 1.1000 and four tenths.

Lots, and what one pip pays

Forex trades in standardised sizes. A standard lot is 100,000 units of the base currency, a mini lot is 10,000 and a micro lot is 1,000. Pip value follows mechanically from the size and from which currency the pair is quoted in.

For any pair quoted in US dollars the arithmetic is fixed:

• EUR/USD · 1.00 lot pays $10.00 per pip · 0.10 lot $1.00 · 0.01 lot $0.10
• GBP/USD · 1.00 lot pays $10.00 per pip · 0.10 lot $1.00 · 0.01 lot $0.10
• AUD/USD · 1.00 lot pays $10.00 per pip · 0.10 lot $1.00 · 0.01 lot $0.10

When the dollar is the base currency, one pip per standard lot is 10 units of the quote currency, converted back at the current rate, so the value floats:

• USD/JPY at 150.00 · 1.00 lot pays about $6.67 per pip · 0.10 lot about $0.67
• USD/CHF at 0.9000 · 1.00 lot pays about $11.11 per pip · 0.10 lot about $1.11

The pattern to internalise: dollar-quoted pairs pay a round $10 per pip per standard lot, everything else needs a conversion. Assuming $10 everywhere is the single most common sizing error on yen pairs.

Leverage changes margin, not risk

Leverage decides how much of your account is reserved as margin to hold a position open. It does not decide how much you lose when your stop is hit. Those are different quantities, and confusing them is how beginners end up oversized.

A worked example. You open 1.00 lot of EUR/USD at 1.1000, a notional value of $110,000:

• At 1:100 leverage, the margin reserved is $1,100.
• At 1:50, margin is $2,200.
• At 1:25, margin is $4,400.

Now place a stop 30 pips away. In all three cases the stop-out costs 30 pips at $10 a pip, which is $300. Same trade, same risk, three different margin figures. Leverage moved the deposit, not the danger.

This is why plans with different leverage are not automatically riskier or safer on that number alone. FFUNDED plans run from 1:25 on Instant Lite and 1:33 on Instant Standard up to 1:50 on the 1-step plans and 1:100 on the 2-step plans, and the comparison that actually matters between them is drawdown room and targets, which you can line up on the compare plans page. Higher leverage only becomes higher risk when the freed-up margin tempts you into more size than your stop maths allows.

Size from the stop backwards

Correct sizing never starts with "how many lots can I open". It starts with the stop:

1. Decide risk per trade in money. On a $100,000 account risking 0.5%, that is $500.
2. Measure the stop in pips from the chart, not from a wish. Say 25 pips.
3. Divide money risk by stop distance: $500 over 25 pips is $20 per pip.
4. Convert to lots. On EUR/USD at $10 per pip per lot, $20 per pip is 2.00 lots.

Run the same numbers with a 50-pip stop and the answer halves to 1.00 lot. The stop distance sets the size; the size never sets the stop. On a drawdown-limited account this one habit is what keeps a normal losing streak from reaching the limit, and it is worth reading the fuller treatment in position sizing on a funded account alongside how drawdown rules actually work.

The mistakes this maths prevents

• Sizing to margin. "I have margin for five lots" is an observation about leverage, not a reason to trade five lots.
• Flat pip assumptions. Two lots of USD/JPY do not risk the same per pip as two lots of GBP/USD. Check the quote currency.
• Widening stops without resizing. Moving a stop from 20 to 40 pips on unchanged size silently doubles the money at risk.
• Doubling after losses. The arithmetic above only protects you if the risk percentage stays fixed when you are down.

Frequently asked questions

What is a pip worth on USD/JPY?

One pip on USD/JPY is 0.01, worth 1,000 yen per standard lot, which you convert at the current rate. At 150.00 that is about $6.67 per pip per 1.00 lot, and it shifts as the rate moves, unlike the fixed $10 of dollar-quoted pairs.

Does higher leverage mean higher risk?

Not by itself. Leverage sets how much margin a position reserves, while risk is set by position size and stop distance. Higher leverage becomes dangerous only when the extra margin headroom tempts you into sizes your stop arithmetic does not justify.

What lot size should I use on a $100,000 account?

There is no fixed answer, because correct size depends on the stop. Decide risk in money first, divide by stop distance in pips, then convert using the pair's pip value. A $500 risk with a 25-pip stop on EUR/USD gives 2.00 lots, while the same risk with a 100-pip stop gives 0.50.

What is the difference between a pip and a pipette?

A pip is the standard quote increment, the fourth decimal on most pairs and the second on yen pairs. A pipette is one tenth of that, the extra digit most platforms display, used mainly to quote spreads and fills precisely.
