Maximum Drawdown Calculation and Recovery Calculator

What Is Maximum Drawdown? Definition and Formula

Maximum drawdown (often written max drawdown or MDD) is the biggest fall in an account from a high point to a later low point, before a new high is made. It is shown as a percentage of the high. It tells you the worst stretch of the period you looked at, which a final profit figure hides.

Formula: Maximum drawdown % = (peak value - trough value) / peak value x 100. The peak must come before the trough. If an account goes from ₹6,00,000 down to ₹4,80,000, the drawdown is ₹1,20,000 and the percentage is 20%.

Drawdown is different from a loss on one trade and from volatility. A single losing trade can be small while a run of losses builds a deep drawdown. Volatility measures how much values swing in both directions, while drawdown looks only at the fall from a high.

Maximum drawdown is the largest percentage fall from an earlier account high to a later low within the period you examine. The calculation is (peak − trough) ÷ peak × 100. This calculator checks a peak and trough you enter; it does not search your trade history for them. It also compares your current account value with that peak and works out the gain needed from the trough to recover. Choose the correct pair in time order before entering the amounts.

Find the worst decline before using the form

A trough is a low point reached after the peak being measured. Taking the highest and lowest account values from a period without checking their dates can create a decline that never happened. A low that occurred before the high cannot be the trough for that high.

The CFA Institute GIPS handbook describes maximum drawdown by comparing peak-to-trough percentage losses within a specified period. Its rules for fiduciary managers have their own reporting scope; they are not a requirement imposed on personal trading accounts.

For a manual check, read account values from oldest to newest. Keep the highest value seen so far, calculate the fall from that running high to each later value, and retain the largest percentage fall. The highest rupee loss and largest percentage loss need not identify the same episode if the account grew substantially.

Record the period and observation frequency with the result. End-of-day balances cannot establish the deepest loss experienced during an open trading day. An incomplete record gives a drawdown for that record, rather than proof of the worst decline your account ever experienced.

Calculate Drawdown from a List of Account Values

The calculator above needs one peak and one trough. If you have a list of account values, such as your closing balance after each day or week, use the running-peak method to find them:

1. Write the values in date order, oldest first.
2. Next to each value, write the highest value seen so far (the running peak).
3. For each row, work out (running peak - value) / running peak x 100. This is the drawdown on that date.
4. The largest of those percentages is the maximum drawdown. The row where it happens gives you the trough, and the running peak on that row gives you the peak.

The deepest row is period 6: the account is at ₹4,80,000 against a running peak of ₹6,00,000, which is a 20.00% drawdown. Enter ₹6,00,000 as the Peak and ₹4,80,000 as the Trough in the calculator to check. Note that period 5 is a 15.00% fall from the same peak and period 8 is back to a 5.00% fall, so the account is still below its high in the last row.

Use values taken at the same time of day and on the same basis, for example closing balances including open positions. Deposits and withdrawals must be taken out, or a large deposit will hide a loss. A spreadsheet makes this easy with a running maximum column.

The four account amounts this page accepts

• Peak Account Value: the high at the start of the decline you have identified.
• Trough Account Value: the later low belonging to that decline. It should not exceed the peak.
• Initial Capital: the starting balance used for the tool’s simple Total Return % calculation.
• Current Account Value: the present value used to measure current distance below the entered peak and recovery progress.

These are manual rupee inputs. There are no date, symbol, historical-price series, benchmark or fee fields. The form cannot tell whether you selected the worst episode or whether the peak really preceded the trough. It also cannot separate deposits and withdrawals from trading gains and losses.

Use a consistent account-value basis. For a review of equity including open positions, keep those positions in each observation. For a closed-trade review, label the result accordingly. If cash was added or removed during the period, a comparison of raw balances can confuse funding changes with performance; reconcile those movements before calling the result a trading return.

Worked account example: decline and partial recovery

Illustrative account figures: Peak Account Value ₹6,00,000, Trough Account Value ₹4,80,000, Initial Capital ₹4,00,000 and Current Account Value ₹5,40,000. Assume no deposits or withdrawals and consistent valuation of the account. These are made-up values, not market history.

The account is profitable compared with its initial capital while remaining below its peak. Those statements can both be true. Total Return % answers how far the present balance is above the starting balance; Current Drawdown % answers how far it is below the selected high.

Recovery Progress % means half of the rupee decline has been regained in this example. It does not mean that the current account needs a gain equal to half the original recovery percentage. From ₹5,40,000, the remaining ₹60,000 requires 60,000 ÷ 5,40,000 × 100 = 11.11% to reach the old high.

Why the recovery percentage is larger

The fall is measured against the larger peak; recovery starts from the smaller trough. Using a different starting amount explains the unequal percentages. CME Group’s risk lesson illustrates the same relationship between a loss and the gain required to regain it.

The tool’s Recovery % Needed is calculated from the trough you entered. It does not update that starting point to the current balance. Read it alongside Current Drawdown % rather than assuming both fields describe the remaining journey from today.

If you need to compare net profit with the amount of drawdown, the recovery factor calculator addresses a different question. For a cash limit on an individual trade, the risk per trade calculator uses a different denominator again.

Recovery Gain Needed: Reference Table

The gain needed to get back to the old high is the fall divided by what is left: recovery % = drawdown % / (100 - drawdown %) x 100. The deeper the fall, the faster the required gain grows.

A 10% fall needs 11.11% to recover, but a 50% fall needs 100%, which means doubling the money. This is why limiting the size of the fall matters more than chasing a quick recovery. How long recovery takes depends on future results, which no calculator can know.

The Est. Months to Recover card uses a hidden assumption: it divides the drawdown percentage by 3 and rounds up, as if the account grew 3% a month. For the 20% example that gives 7 months. There is no input for your own return, so treat the number as a rough illustration only.

Outputs that require extra caution

Drawdown Severity, Status and Recommendation are preset labels generated from the entered figures. They do not establish a safe loss threshold for your account. A label such as Normal should not be read as permission to accept a loss or continue trading.

Est. Months to Recover is a fixed shortcut based on the entered drawdown. There is no return-assumption field, date input or future trade sequence. The number therefore cannot tell you when your account will regain its peak. Recovery depends on future results, which this form cannot know.

The displayed Calmar Ratio divides the simple Total Return % by Maximum Drawdown %. It does not annualise the return or identify a measurement period. Avoid comparing it with a published ratio based on a different return method or time window.

The implementation also swaps peak and trough if they are reversed. Zero-valued account entries revert to built-in defaults, so the form cannot accurately represent a wiped-out balance. Correct the values yourself so that the form reflects a real decline. If the current balance has fallen below the entered trough or risen above the entered peak, revisit the selected episode: the original pair may no longer describe the maximum drawdown for your updated record.

OneTradeJournal’s manual trade records and equity-curve and drawdown reports can support a review of logged results. Keep the actual losses, account funding and open-position exposure distinguishable in your notes. A prop account has separate breach rules; use the prop firm drawdown calculator only after checking the provider’s own definitions.

What Is an Acceptable Drawdown for a Trader?

There is no standard answer, and published benchmarks differ by strategy, market and the person. Acceptable depends on what you can bear, on the size of your risk per trade and on how many losses in a row your plan can produce.

A long losing run produces a drawdown that you can estimate from your risk per trade. Losing a fixed share of the account on each of N trades in a row leaves (1 - risk) raised to the power N. These made-up examples show 10 losses in a row:

Use it backwards: pick the deepest fall you could live with, then size each trade so that a long losing run stays inside it. Our position size guide and risk of ruin calculator help with that, and the drawdown glossary page has a short definition.

The Drawdown Severity label on this page is a preset text based on fixed percentage cut-offs inside the tool. It is not an official safe limit.

Static and Trailing Drawdown Limits on Prop Accounts

Some funded-account providers set a maximum loss rule. A static limit is a fixed floor under the starting balance. A trailing limit moves up as your account high rises, so the same loss gets less room as you win. Example with made-up numbers: a ₹10,00,000 account with a 10% limit has a static floor of ₹9,00,000. With a trailing limit that follows the highest balance, a rise to ₹11,00,000 moves the floor to ₹9,90,000. Each provider words and applies its rule differently, for example whether it counts open profit, so read the provider's own terms. See trailing drawdown explained and the prop firm drawdown calculator.

Drawdown and the Calmar Ratio

The Calmar ratio compares return with drawdown. The usual definition is the annualised return divided by the maximum drawdown over a set period, often three years. A made-up example: a 30% yearly return with a 15% maximum drawdown gives a Calmar ratio of 2. A higher figure means more return for each unit of worst fall.

The Calmar Ratio card in this calculator is different. It divides the simple Total Return % (current value against initial capital) by the maximum drawdown, with no annualising and no fixed period. Do not compare it with published Calmar ratios. The recovery factor calculator compares net profit with the largest drawdown in rupees.

Track Your Drawdown in a Trading Journal

A drawdown is easier to learn from when you can see which trades built it. In OneTradeJournal you log trades by hand, with stop, target, strategy, emotions, mistakes and plan deviation. The equity curve and drawdown reports then show when the account fell and which entries sat inside that stretch. It does not import broker data, and the paid AI features can be wrong. Keep deposits and withdrawals out of your trade results so that drawdown reflects trading alone.
