What is profit buffer?
A profit buffer is the minimum gain you must build on a funded account before you can request a withdrawal. It acts as a cushion for the firm and delays the first payout.
It is a quiet constraint, absent from sales pages, and it often pushes the first payment back by several weeks.
The principle
Before allowing a withdrawal, several firms require the account to have accumulated a realised gain of a certain size — sometimes expressed as a percentage of capital, sometimes as an absolute figure.
That amount stays on the account after the withdrawal: you only take out what exceeds the buffer. It works, in effect, as a security deposit built from your own profits.
Why firms impose it
The stated logic is a safety cushion. An account that has just been funded and immediately pays out its first gains starts again with an intact drawdown margin but no reserve. The buffer guarantees that part of the profit stays available to absorb a losing run.
It also has a less avowable economic effect: it defers the cash outflow and raises the odds that a risk incident occurs before the first payment.
How it compounds
The buffer stacks on two constraints that are usually already there: the minimum waiting period before a first withdrawal, and the minimum amount per request.
A trader who has to build a buffer, wait fourteen days and reach a withdrawal floor can end up receiving a first payment a month after being funded — even though the account was profitable in its first week.
The question to ask
Before buying, ask explicitly: how much must I have earned before I can request my first withdrawal, and does that amount stay locked afterwards?
The answer is almost never on the website, and it determines your real cash position far more reliably than the profit split percentage does.

- Drawdown Drawdown is the maximum loss allowed on a prop firm account before it is closed. It is expressed as a percentage or a fixed amount, and calculated under three models — static, end-of-day trailing or intraday trailing — with very different consequences.
- Funded account A funded account is the trading account a prop firm allocates once the evaluation is passed. The trader operates under continuing risk rules and keeps a share of the profits, without ever holding the nominal capital.
- Payout A payout is the actual transfer of a funded trader's gains. It follows a cycle specific to each firm, after a minimum period since the account was opened, and often above a floor amount.
- Profit split The profit split is the share of gains paid back to the trader on a funded account. It generally sits between 80 and 90 %, and can reach 100 % at some firms through a scaling plan or a promotional offer.
