Prop accounts fail on the daily loss limit far more often than on the overall one, and almost always because nobody was tracking how close they were. The daily limit resets, so it feels forgiving — but it is measured from where the day opened, and two ordinary losses can eat most of it before lunch.
This calculator holds both limits side by side and tells you which one bites first. That is the only number that matters before the next entry, because breaching either one ends the account regardless of how much room the other still has.
When to use it
- Before every trade on a funded or challenge account.
- After a loss, to see whether there is room left for the next setup.
- When deciding position size — the room left is the real risk budget.
- When comparing firms, since a 4% daily limit is a very different account from a 5% one.
Two floors, measured from different starting points. The higher one is the one that ends the account.
Daily Floor = Day Start Equity − (Account Size × Daily Limit %)
Overall Floor = Account Size − (Account Size × Overall Limit %)
Room Left = Current Equity − the higher of the two floors- Most firms measure the daily limit against the balance or equity at the day's open, not against the account size — check which, because it changes the floor after a profitable day.
- Firms using a trailing drawdown move the overall floor up as the account grows. This calculator assumes a static floor, which is the more common rule.
- Floating losses on open positions usually count. A position sitting at −$2,000 unrealised has already used that room.
A $100,000 account with a 5% daily limit and a 10% overall limit. The day opened at $100,000 and equity is now $98,000.
Working: the daily floor sits $3,000 below current equity and the overall floor $8,000 below, so the daily limit bites first. Anything risking more than $3,000 today can end the account even though the overall limit looks comfortable.
Is the daily limit measured from balance or equity?
It varies by firm. Most use the higher of balance or equity at the daily reset, which favours you after a winning day. Read the rule before assuming — it moves the floor by whatever you made yesterday.
Do floating losses count towards the limit?
At almost every firm, yes. The limit is checked against equity, which includes open positions. A trade sitting deep in the red has already used the room even though it has not closed.
What is a trailing drawdown?
The overall floor follows your highest equity upward, usually until it reaches the starting balance. It means profit does not create permanent room, and it is stricter than a static floor.
When does the daily limit reset?
Usually at 5pm New York time, which is the rollover most firms use. It is not midnight where you live, and the difference has cost plenty of accounts.
