# Calculating the Value-at-Risk when changing the confidence level

If I have a VaR estimate at a 95% confidence interval is 10, how do I calculate the approximate level of the VaR if the confidence level was raised to 99%, assuming a one-tailed normal distribution?

If you assume that everything is normally distributed, then you just divide by normsinv(95%) and multiply by normsinv(99%).

• Thank you, I wasn't sure if there is a non-excel function or not for this but this answer gives the correct value, thanks for your help!
