How to Calculate Pip Value by Pair in Forex

A pip is not always worth $10. It’s worth $10 on some pairs, in some account currencies, at some lot sizes — and on everything else it’s a number you have to work out. Traders who memorize “$10 a pip” and stop there end up sizing USD/JPY and EUR/GBP positions wrong, then wonder why their risk doesn’t match their plan. Here’s how to get the real number for any pair.

The whole thing comes down to one idea most explanations skip: pip value is settled in the quote currency first, then converted into your account currency. When those two currencies are the same, the value is fixed. When they’re different, it moves with the exchange rate. That single fork explains every “why is my pip value weird” question in prop trading.

Pip value = pip size × position size in units, measured in the quote currency, then converted to your account currency. For a standard lot (100,000 units) on a four-decimal pair, that’s 10 units of the quote currency per pip. If the quote currency matches your account currency, the value is fixed; if it doesn’t, it shifts with the live rate.

The formula is one line — the conversion is where people slip

Pip value in the quote currency = pip size × units traded. That’s the entire calculation before conversion. A pip is the standard smallest price increment for the pair, and the units are however many you’re trading (a standard lot is 100,000 units). Multiply the two and you have the value of one pip — expressed in the second currency of the pair.

That last part is the catch. EUR/USD is quoted in USD, so its pip value comes out in USD. USD/JPY is quoted in JPY, so its pip value comes out in yen, and a yen figure is useless to you until it’s turned into the currency your account is actually denominated in. The formula is trivial; the conversion step is the one people drop.

Pip size depends on the pair, and JPY pairs are the exception

For almost every pair, one pip is 0.0001 — the fourth decimal place. The major exception is any pair quoted in Japanese yen, where one pip is 0.01, the second decimal place, because yen prices carry fewer decimals. Get this wrong and your pip value is off by a factor of 100 before you even start.

Pair type	One pip	Example
Standard (4-decimal)	0.0001	EUR/USD 1.0832 → 1.0833
JPY pairs (2-decimal)	0.01	USD/JPY 150.20 → 150.21

Whether you trade the major forex pairs or crosses, the decimal rule is the same: yen on one side means 0.01, everything else means 0.0001.

Lot size scales pip value in a straight line

Pip value moves proportionally with the number of units you trade, so once you know the standard-lot value you know every other size. Cut the lot size by ten, cut the pip value by ten. For a USD-quoted pair held in a USD account, the tiers look like this:

Lot	Units	Pip value (USD-quoted pair)
Standard	100,000	$10.00
Mini	10,000	$1.00
Micro	1,000	$0.10

Trading 0.30 lots? That’s three micro-lot units of $0.10 wait — no: 0.30 of a standard lot is 30,000 units, so $3.00 a pip. Keep it simple: take the standard-lot value and multiply by your lot fraction.

The rule that decides whether pip value is fixed or moves

Pip value is fixed only when the pair’s quote currency is the same as your account currency — otherwise it shifts every time the exchange rate does. This is the angle the calculators hide behind a button, and it’s the whole reason “$10 a pip” fails. There are three cases, and you can sort any pair into one in a second.

Case 1 — Quote currency = account currency (fixed)

If you hold a USD account and trade a pair quoted in USD — EUR/USD, GBP/USD, AUD/USD — the pip value is locked at $10 per standard lot and never moves. No conversion, no live rate, nothing to recalculate. This is the only case where the number you memorized is actually true.

Case 2 — Pair has USD as the base, account is USD (shifts)

When USD is the first currency — USD/JPY, USD/CAD, USD/CHF — the pip value lands in the quote currency and has to be divided by the live rate to come back to dollars. Because that rate moves, your pip value moves with it. USD/JPY at 150 is not the same pip value as USD/JPY at 160.

Case 3 — A cross with no USD, USD account (shifts)

Crosses like EUR/GBP or EUR/JPY settle in a third currency, so you convert through that currency’s rate against the dollar — and again, the value drifts as the rate drifts. These are the pairs people most often size wrong, because the pip value can sit well above or below $10.

Pip value by pair, worked out (USD account, standard lot)

Here’s the calculation run for one standard lot on a USD account, so you can see the fixed pairs sitting flat at $10 while the others wander. The exchange rates below are illustrative — plug in the live rate when you actually size a trade.

Pair	Quote currency	Pip value / standard lot	Fixed or shifts?
EUR/USD	USD	$10.00	Fixed
GBP/USD	USD	$10.00	Fixed
AUD/USD	USD	$10.00	Fixed
USD/JPY	JPY	≈ $6.67 (at 150.00)	Shifts with USD/JPY
USD/CAD	CAD	≈ $7.35 (at 1.3600)	Shifts with USD/CAD
EUR/GBP	GBP	≈ $12.70 (at GBP/USD 1.2700)	Shifts with GBP/USD
EUR/JPY	JPY	≈ $6.67 (at USD/JPY 150.00)	Shifts with USD/JPY

Two of those are worth seeing in full. USD/JPY: one pip on a standard lot is 0.01 × 100,000 = 1,000 yen; divide by the rate, 1,000 ÷ 150 = $6.67. EUR/GBP: one pip is 0.0001 × 100,000 = 10 GBP; multiply by GBP/USD, 10 × 1.27 = $12.70. Same formula both times — the only difference is which rate you convert through.

If your account isn’t in USD, even EUR/USD moves

“Fixed” is relative to your account currency, not the dollar — so a non-USD account changes which pairs are stable. Take a EUR-denominated account trading EUR/USD. The pip value is still $10 in the quote currency, but you have to convert that back to euros: $10 ÷ EUR/USD. At a rate of 1.0800 that’s €9.26 a pip, and it drifts as EUR/USD moves. The pair that was rock-solid for a USD trader is now a moving target for a EUR trader.

The rule doesn’t change, only the reference point does. Find the quote currency, compare it to your account currency, and if they differ, convert through the live rate. Same three cases, just measured from where your balance actually sits.

From pip value to position size

Pip value is the input you need before you can size a position correctly, because risk is just stop distance multiplied by pip value multiplied by lots. The position-size formula is: lots = dollars you’re willing to risk ÷ (stop in pips × pip value per lot). Get the pip value wrong and every position you size inherits that error.

Worked on a $100,000 account capping single-trade risk at 1% ($1,000) with a 20-pip stop: on EUR/USD at $10 a pip, that’s $1,000 ÷ (20 × $10) = 5.0 standard lots. On USD/JPY at roughly $6.67 a pip, the same $1,000 and same 20-pip stop allows $1,000 ÷ (20 × $6.67) = ≈ 7.5 standard lots. Same risk, same stop, very different lot size — purely because the pip values differ. Size USD/JPY as if it were $10 a pip and you’d quietly be risking a third less than you intended.

If you’d rather not run this by hand on every trade, a lot size calculator bakes the pip-value step in, and it’s worth understanding how pip value interacts with leverage before you scale size up. The math here is the same whether you’re on a personal account or working to get a funded account.

Why this matters for your drawdown limit

On an evaluation account, a mis-sized position doesn’t just cost money — it eats into a hard drawdown limit you can’t breach. PropLynq’s Two-Step challenge on a $100,000 account runs a 5% daily drawdown ($5,000) and a 10% maximum ($10,000), so every position’s real risk has to sit comfortably inside that $5,000 daily floor. PropLynq structures the limit as a fixed dollar amount, which is exactly why the pip-value step matters: if your sizing assumes $10 a pip on a pair that’s really $12.70, your true risk against that daily limit is 27% higher than your plan says.

This is also why pair selection and account type interact. A trader who understands how the limit resets — see trailing drawdown versus a static one — and who sizes from the correct pip value keeps real risk and planned risk in agreement. That alignment is most of what passing an evaluation actually requires.

Three mistakes that give you the wrong pip value

Almost every pip-value error traces back to one of three shortcuts. Each one is easy to catch once you know to look for it.

• Assuming $10 a pip on every pair. It’s only true for USD-quoted pairs in a USD account. On USD/JPY, crosses, or any non-USD account, it’s wrong — sometimes badly.
• Forgetting JPY pairs use two decimals. A pip on USD/JPY is 0.01, not 0.0001. Use the wrong pip size and your value is off by a factor of 100.
• Skipping the account-currency conversion. The raw pip value is in the quote currency. If that’s not your account currency, you must convert it through the live rate, or your risk numbers are fiction.

The short version

Find the quote currency, multiply pip size by units to get the pip value in that currency, then convert it to your account currency at the live rate. If quote and account currency match, you’re done and the number is fixed; if they don’t, the value shifts and you recompute when it matters. That’s the entire skill — and it’s the difference between a position sized to your plan and one sized to a number you assumed. It’s the same discipline any serious prop firm expects before you risk a funded balance.

PropLynq’s $100,000 Two-Step challenge uses a 5% daily and 10% maximum drawdown — size from the correct pip value and that limit stays a guardrail, not a trapdoor.
