Video Completion Rate (VCR) is a metric used in digital advertising to measure the percentage of viewers who watch a video ad to its completion. It provides insights into the effectiveness of a video ad campaign by indicating how engaging the content is and how successful it is at retaining viewers until the end.

The formula to calculate Video Completion Rate (VCR) is:

VCR = (Number of Completed Views / Number of Video Starts) * 100

The result typically takes the form of a percentage. For instance, if a video ad starts playing 1,000 times and 700 viewers watch it until the end, the VCR would be 70%.
