What Is PnL in Trading?
PnL means Profit and Loss (also written P&L or P/L) — the running total of what a trade, a day, or a whole account has gained or lost. A positive PnL means you're in profit; a negative PnL means you're down. It is the single number every trader, and every prop firm, watches most closely.

Realized vs unrealized PnL
There are two halves to your PnL, and confusing them is what blows up funded accounts:
- ▸ Realized PnL — profit or loss locked in from positions you've already closed. It's real cash sitting in your balance and can't change.
- ▸ Unrealized PnL (a.k.a. floating or open PnL) — profit or loss on positions still open. It moves tick by tick with the market and isn't final until you close.
Your total PnL = realized + unrealized. Prop firms usually measure drawdown against this combined figure, so a big floating loss can breach your limit even before you've closed the trade.
How to calculate PnL
The core formula depends on your trade direction:
Worked example. You buy 1 standard FX lot at 1.1000 and close at 1.1050 — a 50-pip gain. At roughly $10 per pip, that's +$500 gross. After, say, $7 in commission your net realized PnL is +$493. Many platforms also show PnL as a percentage of your balance, which is the figure prop firm drawdown and profit-target rules actually use.
Why PnL decides everything at a prop firm
At a proprietary trading firm, nearly every rule is measured against PnL — which is why understanding it is the difference between getting paid and getting breached:
- ▸ Profit target is just a required PnL (e.g. +8% of the account).
- ▸ Daily & max drawdown limits track how far your combined PnL can fall before the account fails.
- ▸ The consistency rule caps how much of your total PnL can come from one day.
- ▸ Your payout is a percentage (the profit split) of your realized PnL.
In short: trade for steady, realized PnL and watch your floating PnL against the drawdown line in real time. For the full rulebook, see prop firm rules explained and drawdown types explained.
PnL FAQ
What does PnL mean?▾
PnL stands for Profit and Loss. It's the net amount a position or account has made or lost over a period — total gains minus total losses. A positive PnL means you're up; a negative PnL means you're down. Traders track it per trade, per day, and as a running account total.
What is the difference between realized and unrealized PnL?▾
Realized PnL is locked in from positions you've already closed — it's actual cash in your balance. Unrealized (or 'floating') PnL is the paper profit or loss on positions still open; it moves with the market and isn't final until you close the trade. Your total PnL is realized plus unrealized.
How do you calculate PnL?▾
For a long trade: PnL = (exit price − entry price) × position size. For a short: PnL = (entry price − exit price) × position size. Subtract commissions and swap/financing fees for net PnL. Example: buy 1 lot at 1.1000 and sell at 1.1050 = +50 pips; at $10/pip that's +$500 gross PnL.
Why does PnL matter at a prop firm?▾
Almost every prop firm rule is measured against PnL. Your daily and maximum drawdown limits track your floating and closed PnL, the profit target is a PnL threshold, and the consistency rule caps how much of your total PnL can come from one day. Your payout is a percentage of your realized PnL. If you don't watch PnL in real time, you can breach a rule before you notice.
What is a good daily PnL?▾
There's no universal number — it depends on account size and risk. A common professional benchmark is a steady 0.25–1% of account equity per day, compounding into a few percent per month. Chasing an outsized single-day PnL is exactly what trips the consistency rule and the daily-drawdown limit at funded firms, so consistency beats one big green day.
What does P&L stand for?▾
P&L stands for Profit and Loss — it's the same thing as PnL, just written with an ampersand. You'll see it as PnL, P&L or P/L across trading platforms and accounting; they all mean the net of your gains minus your losses over a period.
What is a P&L statement?▾
A P&L statement (profit-and-loss statement) is a summary of income minus expenses over a period — in business it's one of the three core financial statements. In trading, your 'P&L' is the running profit or loss on your positions and account, which your broker or prop firm reports per trade, per day and as a total.
What is unrealized PnL in crypto?▾
Unrealized PnL (also called floating PnL) is the profit or loss on an open position that you haven't closed yet — it moves with the live price and only becomes real once you close. In crypto it's especially visible because markets trade 24/7, so your unrealized PnL keeps changing overnight and on weekends. It's identical in concept across crypto, forex and stocks.
