What does the page calculator do?
Maximum Drawdown Calculator works out the max drawdown from the Peak Value and Trough Value, following standard Finance conventions — the page defaults produce a max drawdown of -25.0%.
- Inputs: Peak Value and Trough Value.
- Output: the max drawdown, plus the intermediate steps behind it.
- Method: the standard Finance formula, evaluated entirely in your browser.
Quick answer
With the default inputs (peak value of 100,000, trough value of 75,000), maximum drawdown calculator returns a max drawdown of -25.0%. Assumptions and limits are summarized below.
How does it work?
Maximum Drawdown Calculator computes the max drawdown directly from your inputs — the Peak Value and Trough Value feed the formula. Nothing is uploaded: the math runs locally in your browser and the result appears as you type.
How the Maximum Drawdown Calculator works
Maximum Drawdown Calculator answers one question well — given the values you provide, what is the result? Enter the Peak Value and Trough Value, and the result panel returns the value with the full working underneath.
How to use it
- Peak Value — one of the values the calculation builds from; the result reflects exactly what you type here.
- Trough Value — used in the first stage of the calculation, so entering it accurately matters more than any later refinement.
- The output panel in maximum drawdown calculator leads with the headline result and follows with the steps behind it, so the value can be checked rather than assumed.
- Adjust and re-run. Change one input at a time to see how sensitive the max drawdown is to it — the fastest way to understand what the calculation is doing.
The formula behind the result
The relationship between the inputs is fixed by the formula, and Maximum Drawdown Calculator makes each substitution explicit so nothing about the figure is hidden.
Worked example: with peak value of 100,000, trough value of 75,000, this maximum drawdown calculation returns Max Drawdown: -25.0%. The same run reports Gain needed to recover: +33.3% — recovery always requires a larger percentage gain than the loss itself.
The steps it follows:
- Formula: Drawdown = (Trough − Peak) ÷ Peak × 100
- (75,000 − 100,000) ÷ 100,000 = -0.2500
- × 100 = -25.0%
- Recovery gain needed = Peak ÷ Trough − 1 = +33.3%
Substitute your own values and the same steps produce your answer — that is the point of a calculator that shows its working.
Understanding the result
To interpret the result from maximum drawdown calculator, read it together with the intermediate figures — the pairing is what makes the number auditable.
Where it helps
Maximum Drawdown Calculator fits planning and checking: planning around a target figure, comparing scenarios side by side, and double-checking the max drawdown, or any moment when the figure needs to be right the first time.
Common mistakes
The most common error with Maximum Drawdown Calculator is a unit mismatch — one value entered in different units than its label assumes quietly skews the output. Check each label before typing.
Tip: Run Maximum Drawdown Calculator twice with deliberately low and high inputs; the spread tells you how sensitive the output is, which a single run never shows.
Assumptions and limitations
Maximum Drawdown Calculator assumes the units shown in each label — entering values in different units will skew the result proportionally.
Why use this calculator
Because the page doubles as documentation: Maximum Drawdown Calculator puts the formula, a worked example, and the assumptions right beside the calculator.

Frequently Asked Questions
What does the tool calculate?
Maximum Drawdown Calculator is built for maximum drawdown questions that need a defensible number: the working is always visible, the inputs accept your own values, and the figure updates as you type. Because the working is visible: Maximum Drawdown Calculator shows each operation behind the max drawdown in the steps panel, so you can verify the result instead of trusting a black box.
How is the max drawdown calculated?
The first steps are formula: drawdown = (trough − peak) ÷ peak × 100, then (75,000 − 100,000) ÷ 100,000 = -0.2500. Maximum Drawdown Calculator lists every intermediate step in the result panel, so the derivation of the figure can be checked line by line.
What do I need to use the Maximum Drawdown Calculator?
The Peak Value and Trough Value it asks for, or the page defaults if you just want to see the calculation work. Each input maps directly to the formula, and changing any one of them recalculates the max drawdown instantly.
What does the result from the tool mean?
The main number the maximum drawdown calculator returns is the max drawdown for your exact inputs, and the supporting figures and step list give it context. The model behind Maximum Drawdown Calculator covers the standard case; special cases, edge values, or jurisdiction-specific rules may need manual adjustment.
When is the page most useful?
Typical uses for Maximum Drawdown Calculator include planning around a target figure, comparing scenarios side by side, and double-checking the max drawdown — anywhere the figure needs to be defensible rather than guessed. Run Maximum Drawdown Calculator twice with deliberately low and high inputs; the spread tells you how sensitive the figure is, which a single run never shows.
