How to calculate Requirement Leakage Index ?

Requirements Leakage Index (RLI) gives indication on effectiveness of the requirements evocation process.  Requirements Leakage index can be defined as the ratio of number of missed requirements to number of total requirements. It is always expressed in percentage figure. 
The missed requirements are those that were missed during Requirements evocation process by the Project team.Requirements Leakage Index is always calculated at Project level.
How to calculate Requirement Leakage Index:
Requirements Leakage Index = (No. of Missed Requirements)/ (Total No. of Initial Requirements) *100
No. of Initial Requirements
No. of Missed Requirements
Requirement Leakage  Index

Requirement Leakage Index = 5/100*100
                                              = 5 %
