Value at risk (VaR) is a measure of the risk of loss for investments.

It estimates how much a set of investments might lose (with a given probability), given normal market conditions, in a set time period such as a day.

## What is VaR and how is it calculated?

Incremental VAR is the amount of uncertainty added to, or subtracted from, a portfolio due to buying or selling of an investment. Incremental VAR is calculated by taking into consideration the portfolio’s standard deviation and rate of return, and the individual investment’s rate of return and portfolio share.

## What risk does VaR measure?

Value at risk (VaR) is a statistic that measures and quantifies the level of financial risk within a firm, portfolio or position over a specific time frame.

## What is VaR calculation?

Value at Risk (VAR) calculates the maximum loss expected (or worst case scenario) on an investment, over a given time period and given a specified degree of confidence. We looked at three methods commonly used to calculate VAR.

## What does 95% VaR mean?

It is defined as the maximum dollar amount expected to be lost over a given time horizon, at a pre-defined confidence level. For example, if the 95% one-month VAR is $1 million, there is 95% confidence that over the next month the portfolio will not lose more than $1 million.
