Value at Risk (VaR) Calculator
Calculate Parametric Value at Risk (VaR), Conditional VaR (Expected Shortfall), and portfolio tail risk at 90%, 95%, and 99% confidence.
What is the Value at Risk (VaR) Calculator?
Value at Risk (VaR) quantifies the maximum potential monetary loss an asset portfolio could suffer across a specific holding timeframe at a defined statistical confidence. It models historical price distributions, asset volatilities, and cross-asset correlation matrices using parametric, historical simulation, or Monte Carlo computational techniques. This provides risk managers and financial institutions with standard regulatory metrics to maintain statutory capital reserves and limit catastrophic portfolio loss exposures.
Value at Risk (VaR) is the institutional risk management benchmark that answers the fundamental question: 'What is the maximum dollar amount I can expect to lose on my portfolio over a specific time horizon at a given statistical confidence level?'

How to Use the Value at Risk (VaR) Calculator
Follow these 3 simple steps for instant, accurate calculations.
1. Enter Portfolio Value ($)
Input the total monetary value of your investment portfolio or trading position (e.g., $1,000,000).
2. Set Confidence Level & Time Horizon
Choose your statistical confidence level (e.g., 95% Z=1.645 or 99% Z=2.326) and holding period in days.
3. Specify Volatility & Expected Return
Input annualized standard deviation (volatility) and expected return to compute the maximum expected dollar loss.

Parametric Value at Risk (VaR) Formula
Calculates the maximum expected dollar loss by multiplying portfolio value by the normal distribution Z-score, scaled volatility, minus expected return.
Core Value at Risk (VaR) Calculator Inputs & Terminology
The maximum dollar or percentage loss not expected to be exceeded over a given time horizon at a defined confidence level.
The statistical probability that the portfolio loss will not exceed the calculated VaR (typically 95% or 99%).
The time horizon over which potential portfolio losses are evaluated (e.g. 1-day, 10-day, or 30-day).
The average expected loss in the extreme tail scenarios where the loss exceeds the VaR threshold.
