Lead velocity rate (LVR) is the month-over-month percentage growth in your qualified leads — a leading indicator of future revenue.
LVR (%) = ((qualified leads this month − qualified leads last month) ÷ qualified leads last month) × 100
You finished last month with 400 qualified leads and this month with 460.
((460 − 400) ÷ 400) × 100 = (60 ÷ 400) × 100 = 15% lead velocity rate
Lead velocity rate measures how fast your pipeline of qualified leads is growing month over month. It takes the number of qualified leads this month against last month and expresses the change as a percentage. Popularised by Jason Lemkin of SaaStr, LVR is prized as a real-time, forward-looking metric: leads today become revenue tomorrow, so the rate at which leads grow predicts the rate at which revenue will grow.
Its value is that it leads rather than lags. Revenue, MRR, and bookings tell you what already happened; LVR tells you what is coming, because the qualified leads building up now will close over the following weeks and months. A steadily rising LVR is one of the earliest signals that future revenue growth is healthy, while a stalling LVR warns of a revenue slowdown long before it shows up in the MRR chart.
The metric is only as good as the word "qualified". Counting every raw sign-up or unvetted contact inflates LVR with leads that will never convert, so the discipline is to apply a consistent qualification bar — typically marketing- or sales-qualified leads — every month. Used that way, LVR pairs naturally with conversion rates and sales-cycle length to forecast pipeline into revenue.
Lead velocity rate is one of the few genuinely leading growth indicators — it moves before revenue, so a rising LVR gives early confidence that future MRR growth is on track while a stalling one flags a slowdown months ahead of the revenue chart. That early signal makes it invaluable for forecasting and for catching pipeline problems while there is still time to fix them, provided the lead-qualification bar stays consistent.
High-growth SaaS often target an LVR meaningfully above their revenue growth rate — Jason Lemkin/SaaStr suggest aiming for sustained strong monthly lead growth that stays meaningfully ahead of revenue growth — so that pipeline keeps pace with revenue ambitions; the figure is judged on consistency and trend rather than an absolute level (source: SaaStr / Jason Lemkin).
Because qualified leads convert into customers over the following weeks and months, the rate at which leads grow today predicts the rate at which revenue grows tomorrow. Revenue and MRR are lagging measures, so a rising LVR signals future growth before it appears in those figures.
A lead that has met a consistent qualification bar — typically a marketing- or sales-qualified lead — rather than every raw sign-up. Counting unvetted contacts inflates LVR with leads that will never convert, so applying the same definition every month is essential.
LVR pairs with your lead-to-customer conversion rate and sales-cycle length to project pipeline into revenue. A steady LVR feeds directly into growth forecasts, giving an earlier and often more reliable read than extrapolating past revenue alone.
