What is Drawdown Calculator?
The Drawdown Calculator is a risk management tool used in trading and investing to measure the decline from a portfolio’s highest value to a lower value during a losing period. It shows how much capital has been lost before recovery happens and helps traders understand the real impact of losses.
Drawdown is one of the most important risk metrics because it shows downside exposure, not just profit potential. A strategy may look strong on paper, but if it suffers huge drawdowns, it can be very difficult to recover in practice.
For example, if your account drops by 20%, you need a 25% gain to get back to break-even. If it drops by 50%, you need a 100% gain just to return to your starting point. This is why protecting capital matters more than chasing large returns.
Why Drawdown Matters
Drawdown matters because losses and gains are not symmetrical. A small loss can be recovered fairly quickly, but large losses require much larger gains to fix. That makes capital preservation a core part of long-term trading success.
Traders use drawdown to compare strategies, control risk, and avoid over-leveraging. Lower drawdown usually means a more stable approach, even if the profit rate is slightly lower.
How Drawdown is Calculated
Required Gain (%) = (1 ÷ (1 − Drawdown)) − 1
Example: if your account falls from $15,000 to $12,000, the drawdown is 20%. To recover from that loss, you need a 25% gain.
Types of Drawdown
- Absolute Drawdown: Loss from the initial deposit.
- Maximum Drawdown: Largest peak-to-trough decline.
- Relative Drawdown: Percentage loss from a peak value.

Frequently Asked Questions
Because a loss reduces your capital base. After that loss, any gain is calculated on a smaller amount, so the recovery percentage must be larger.
No. A 50% loss requires a 100% gain to get back to the original value.
In most cases, yes. Lower drawdown usually means lower risk and better capital preservation.
Yes. Enter your initial balance and current balance, and the calculator will compute the percentage drawdown automatically.
It shows how risky a strategy really is and helps you understand whether the returns are worth the potential losses.
