**TL;DR:** Sales velocity tells you how quickly expected revenue moves, CAC tells you what acquisition costs, and LTV tells you what a customer is worth after acquisition. Churn connects the two sides. Use the [free sales metrics calculator](/tools/sales-metrics) to model each metric with consistent inputs.

## What is the difference between sales velocity and CAC? [#what-is-the-difference-between-sales-velocity-and-cac]

Sales velocity is an operating-speed metric. It estimates expected revenue per day from opportunities, deal size, win rate, and cycle length. CAC is an efficiency metric. It divides the cost of sales and marketing by the number of new customers acquired in the same period.

One tells you how fast the funnel can create revenue. The other tells you what it costs to create a customer. A team can have healthy velocity and unhealthy CAC if it closes quickly but spends too much to generate each opportunity.

## How do you calculate sales velocity? [#how-do-you-calculate-sales-velocity]

Use **opportunities × average deal size × win rate ÷ sales-cycle length in days**. If 40 qualified opportunities average $10,000, win at 25%, and take 50 days, estimated velocity is $2,000 per day.

The model is most helpful as a trend. Compare the same segments month over month or quarter over quarter. If velocity slips, break it into inputs rather than asking the team to “sell faster.” The fix may be qualification, pricing, stakeholder access, or simply an inaccurate stage definition.

## How do you calculate customer acquisition cost? [#how-do-you-calculate-customer-acquisition-cost]

Divide sales and marketing spend by new customers acquired during the period. Decide whether to include salaries, commissions, advertising, events, tooling, and agency costs, then use that definition consistently. CAC by channel is usually more actionable than one blended company number.

Beware of mixing spend and customers from different time periods. A campaign may incur cost before its customers close. For longer sales cycles, use a cohort view or clearly label the lag so the metric is not treated as a real-time score.

## How does churn affect LTV? [#how-does-churn-affect-ltv]

Churn shortens the relationship from which lifetime value is earned. A simple LTV model uses average revenue per customer, gross margin, and an expected lifetime based on retention. The exact formula depends on whether you sell subscriptions, projects, or repeat purchases.

LTV-to-CAC is a useful directional ratio, but it can hide poor cash timing. A customer who eventually pays back a high CAC may still strain the business if the sales cycle and onboarding period are long. Track payback alongside the ratio.

## Where Pixelwand CRM fits in [#where-pixelwand-crm-fits-in]

Pixelwand keeps the activities and context behind these metrics closer to the pipeline. Calls can be made from the record, WhatsApp conversations and email can be attached to the relationship, and custom views can segment deals by source or status. That makes the [calculator outputs](/tools/sales-metrics) easier to investigate in a real [CRM workflow](/features).

## Frequently asked questions

**How are sales velocity and CAC related?**

Sales velocity describes how quickly expected revenue moves through the pipeline, while CAC describes what it costs to acquire a customer. Faster velocity can improve cash timing, but it does not automatically lower acquisition cost.

**How do I calculate LTV to CAC?**

Estimate customer lifetime value using gross profit and retention, then divide it by customer acquisition cost. Keep the period, margin, and customer segment consistent in both inputs.

**What does churn tell a sales team?**

Churn shows how much customer base or recurring revenue is lost during a period. Rising churn can make an attractive acquisition model unprofitable even when new-sales metrics look strong.
