Net Asset Value or NAV of a ULIP plan is the value of each unit of the fund on any given day. It is calculated based on the following formula: NAV = (Value of Current Assets + Market Value of Investments Held) - (Value of Current Liabilities & Provisions) / Total number of outstanding units on date. You can visit the website of the insurance provider and use the NAV to find the history of fund performance and also compare it with other funds.
