What Is Drawdown in Trading? The Math That Makes Losses Hard to Undo
Drawdown measures how far your account has fallen from its best point. The trap is the recovery math: the deeper the hole, the more it costs to climb out — which is why controlling drawdown matters more than chasing it back.

Quick answer. Drawdown is the fall from your account's highest value (its peak) to a later low. If the account peaks at $1,000 and drops to $900, the drawdown is $100, or 10%. It measures the whole account from peak to trough, not one trade.
What is drawdown in trading?
Drawdown is the fall from your account's highest value — its peak — to a later low point. It measures the whole account from peak to trough, not the result of a single trade. One losing trade can cause drawdown, but so can a run of small losses, or a mix of small wins and larger losses that leaves you below your best balance.
If your account climbs to $1,000 and then slips to $900, you are in a $100, or 10%, drawdown. The number answers one blunt question: how far are you below your best account value right now? Because your live equity is what keeps positions open, watching that distance is a core survival habit — the reason drawdown sits at the centre of every serious risk plan.
How do you measure drawdown?
You compare the account's peak with its later value — and the peak is the highest point the account reached, not your original deposit. That distinction traps beginners: you can be above what you paid in and still be in a real drawdown.
Drawdown = peak − current value. Drawdown % = (peak − current) ÷ peak × 100.
Say you deposit $1,000, the account grows to $1,080, then falls back to $990. The drawdown is not measured from $1,000. It is measured from the $1,080 peak: $1,080 − $990 = $90, and $90 ÷ $1,080 = 8.33%. You are still $-10 below your deposit's neighbour but, more importantly, you are 8.33% below your best point — that is the figure your risk rules should react to.
Balance, equity, and drawdown — what is the difference?
Balance is the account after closed trades only. Equity is the live value including open profit or loss. Drawdown can be read from either, but a beginner should track equity drawdown, because an open loss is real risk even before it is closed.
| Term | What it means | Example |
|---|---|---|
| Balance | Value after closed trades only | No open trades: balance $1,000 |
| Equity | Value including open trades | One open trade is down $80, so equity is $920 |
| Drawdown | Fall from a peak to a lower value | Peak $1,000, equity $920 = 8% drawdown |
Watch only the balance and an open loss looks harmless because it has not been "realised". But if your peak was $1,000 and an open trade shows −$80, your equity drawdown is already $80 ÷ $1,000 = 8% — and that is the number that can trigger a margin call, not the untouched balance.
Why is a drawdown harder to recover from than it looks?
Because a loss and the gain needed to undo it are not equal once the account has shrunk. After a fall, the recovery gain is always calculated on a smaller base, so the percentage you need back is larger than the percentage you lost. The formula is fixed arithmetic: gain needed = 1 ÷ (1 − drawdown) − 1.
| Drawdown (loss from peak) | Account left from $1,000 | Gain needed to break even |
|---|---|---|
| 5% | $950 | 5.3% |
| 10% | $900 | 11.1% |
| 20% | $800 | 25% |
| 30% | $700 | 42.9% |
| 40% | $600 | 66.7% |
| 50% | $500 | 100% |
| 70% | $300 | 233.3% |
| 90% | $100 | 900% |
A 50% drawdown does not need a 50% gain to recover; it needs 100%, because you must double what is left. This table is arithmetic, not a prediction — but it is the single strongest argument for a defensive habit: avoiding a deep drawdown is far easier than trading back out of one. Shallow losses forgive; deep ones compound against you.
What is maximum drawdown?
Maximum drawdown is the largest peak-to-trough fall over a period — the worst dip before a new high was made. It answers "how bad did it get on the way?", which is a different question from "where did the account finish?".
Take an account that moves $1,000 → $1,050 → $1,020 → $1,100 → $990 → $1,030. The biggest fall runs from the $1,100 peak down to $990: $110, or $110 ÷ $1,100 = 10%. The account ended at $1,030 — up on the start — yet its maximum drawdown was still 10%. A rising ending value can hide a painful trough in the middle, and that trough is what tests your discipline.
How does your risk per trade change your drawdown?
Directly. The share of the account you stake on each trade sets how deep a losing streak can dig. The classic beginner guideline — risk a small, fixed slice per trade, often around 1% — does not stop losses; it controls how far a run of them can take you down. The arithmetic below assumes each next loss is figured on the smaller account left after the previous one.
| Risk per trade | Drawdown after 3 losses | Drawdown after 10 losses |
|---|---|---|
| 1% | 2.97% | 9.56% |
| 2% | 5.88% | 18.29% |
| 5% | 14.26% | 40.13% |
Ten losses in a row at 1% leaves a 9.56% drawdown — annoying, and recoverable with roughly an 11% gain. The same ten losses at 5% leaves a 40% drawdown, which needs about a 67% gain just to break even (read that off Figure 1). This is the bridge from this lesson to the next: how much you risk per trade and how you size the position are the two dials that set your worst-case drawdown before you ever open a chart.
How much drawdown is too much for a beginner?
There is no single safe number that fits every account. A more useful test is behavioural: if a drawdown makes you change the plan — increasing size to "win it back", widening a stop, or avoiding the account altogether — it is already too large, whatever the percentage. Trader-education material commonly describes a 20–30% drawdown as the zone where paralysis and revenge trading set in, one poor decision feeding the next; treat that as a widely-taught warning, not a measured law.
The practical fix most beginner sources agree on is a written circuit breaker, decided before the session: risk a small fixed percentage, and after three losses in a row close the platform for the day (at 1% risk, that run has cost about 3% — one good trade recovers it). Many add an account-level limit too: a monthly loss that ends the month. The point of a rule you cannot negotiate with is that it stops a normal drawdown from becoming an account-ending one while your judgement is impaired.
How can beginners limit drawdown?
Limit drawdown by deciding risk before entry and sizing the trade to it — never the other way around. The goal is not to avoid every loss; it is to stop one mistake from becoming an account-level problem. Work in this order:
- Fix the money you will lose if wrong — a small, fixed share of the account.
- Find the price where the idea is invalid — that is your stop level, read off the chart.
- Measure the distance from entry to that stop, in pips.
- Turn it into a position size using the value per pip for your pair and lot.
- Only then check the margin and whether the account can hold the trade.
Worked example: a $1,000 account, risk limit 1% = $10. If your stop sits 20 pips away and one mini lot is worth about $1 per pip, then 20 pips would cost $20 — twice your limit. To risk only $10 over 20 pips you need $10 ÷ 20 = $0.50 per pip, which is half a mini lot (5,000 units). Size chosen from the loss, not from ambition. If what a pip is is still new, start there; and remember that leverage magnifies drawdown by letting a small deposit carry a large position — in the EU the retail cap on major pairs is 30:1, but the size you actually choose is what sets the loss.
Drawdown mistakes that deepen the hole
| Mistake | Why it hurts | Better action |
|---|---|---|
| Measuring from the deposit, not the peak | Hides losses once the account has grown | Always measure peak → current value |
| Watching balance, ignoring equity | Open losses look less serious than they are | Track live equity drawdown |
| Adding size after losses to "win it back" | Deepens the drawdown and speeds a blow-up | Reduce size, or stop for the day |
| Widening the stop to avoid the loss | The planned small loss becomes a large one | Accept the original invalidation point |
| Thinking a 50% loss needs a 50% gain back | The recovery math is far harder | Check Figure 1 before risking more |
Every one of these is a way of letting a drawdown grow past the plan. A one-line self-check settles most of them: if the account is below its peak, is your next action shrinking the risk or enlarging it? Only one of those answers keeps the recovery math on your side.
Frequently asked questions
What is drawdown in trading, with an example?
Drawdown is the drop from your account's peak to a later low. If your account rises to $1,000 and then falls to $850, the drawdown is $150, or 15%. It is measured from the highest point the account reached, not from your original deposit, so you can be above what you paid in and still be in a drawdown.
What does a 5% drawdown mean?
A 5% drawdown means the account is 5% below its peak value. On a $10,000 account that is a $500 fall from the high point. It is a shallow, ordinary dip: recovering it needs about a 5.3% gain, because the gain is calculated on the smaller $9,500 that is left.
Why does a 50% drawdown need a 100% gain to recover?
Because the gain is figured on the smaller amount left after the loss. A 50% drawdown on $1,000 leaves $500, and getting from $500 back to $1,000 means doubling it — a 100% gain. The general rule is gain needed = 1 divided by (1 minus the drawdown) minus 1, which is why deep losses get exponentially harder to undo.
What is a good maximum drawdown for a beginner?
There is no single safe number that fits everyone. A more reliable test is behavioural: if a drawdown pushes you to increase size, widen stops, or stop checking the account, it is already too large. Keeping risk per trade small — often around 1% — keeps a losing streak shallow enough to stay recoverable and to keep you rational.
Is drawdown the same as a loss?
Not quite. A loss is usually one trade or one closed result, while drawdown is the fall from an account peak to a lower value. A single losing trade can create a drawdown, but several small losses — or open, unrealised losses that reduce your equity — can also combine into a larger one.
