Lead velocity rate is the percentage growth in qualified leads from one month to the next: this month's qualified leads minus last month's, divided by last month's. It is a leading indicator of revenue, since qualified leads convert on a roughly predictable lag of one to two sales cycles. It is only as honest as the definition of qualified; counting unreachable records as leads inflates the rate and the forecast built on it.
LVR is computed on a consistent lead definition, usually sales qualified or sales accepted. A team that changes its MQL threshold mid-year breaks the series. The target is steady positive growth; a 10% monthly LVR compounds to roughly 3x in a year.
The distortion to watch is data quality. If a new bought list adds 2,000 "leads" of which a third are unreachable, LVR jumps for a month and revenue does not follow. Counting only verified, reachable leads in the numerator keeps the indicator predictive.
A team reports 300 qualified leads in August and 345 in September, a 15% LVR. Verification shows 30 of September's were unreachable records from a new source. On reachable leads the figure is 315, a 5% LVR, which matches the revenue that arrives in November.
