Maximum Drawdown Calculator

Calculate the maximum peak-to-trough decline of an investment portfolio before a new peak is attained.

💵

Calculation Parameters

Specify your inputs below.

Calculated Result

Absolute Capital Loss $45,000.00
Maximum Drawdown (MDD) 30.00%
💡

Expert Tip

MDD is a critical risk indicator, reflecting the worst-case historical loss over a specified investment period.

How this Calculator Works

This calculator measures maximum drawdown, an indicator of downside risk. It shows the largest historical loss from a peak value to a trough over a specified timeframe, helping investors assess historical capital preservation. Fund managers use it to evaluate risk mitigation strategies.

Formula & Methodology

Maximum Drawdown = [ (Trough Value - Peak Value) / Peak Value ] * 100 - Peak Value is the highest valuation point reached by the portfolio. - Trough Value is the lowest valuation point reached after the peak.

Step-by-Step Calculation Example

Here is a step-by-step example showing how the calculations are performed:

An investment portfolio reaches a peak value of $150,000, then falls to a low point of $105,000 before recovering. 1. Calculate the absolute decline: $105,000 - $150,000 = -$45,000. 2. Divide by the peak value: -$45,000 / $150,000 = -0.30. 3. Multiply by 100 to get a percentage: -0.30 * 100 = -30%. Result: The Maximum Drawdown (MDD) of the portfolio is -30%.

FAQ

How does compounding frequency impact investment returns?
More frequent compounding (e.g. monthly or daily vs. annually) generates higher effective annual yields (APY) because interest is calculated on accumulated interest earlier in the period.
What is the difference between Sharpe Ratio and Sortino Ratio?
The Sharpe ratio divides excess return by total standard deviation (both upside and downside volatility), whereas the Sortino ratio divides excess return by downside deviation only.
Should investment calculators replace professional wealth management?
No. Investment calculators model financial mathematics under assumed growth rates. Actual market performance fluctuates, so consult a licensed financial planner (CFP) or RIA for personalized advice.
