Method, assumptions and sources

Formulas

Sales needed = target ÷ average deal size, rounded up
Each previous stage = next stage ÷ conversion rate
Cost per sale = leads × cost per lead ÷ sales; reps = meetings ÷ capacity per rep

Assumptions and limits

  • Educational simulation. Rates are constant and there is no time lag: in long sales cycles, today’s leads become sales in later months.
  • Conversion rates vary by industry, channel and deal size. Use your own funnel’s numbers whenever possible.

Frequently asked questions

What is a sales funnel?

The path from first contact to purchase: visitor, lead, qualified lead, meeting, proposal and sale. Each stage converts only part of the previous one, so the conversion rates tell you how many contacts you need at the top to reach a sales target.

Where do I get the conversion rates?

From your CRM or sales spreadsheet: count how many contacts moved from one stage to the next over the last 3 to 6 months. Use consistent stage definitions. If you do not track them yet, start with the final stages (proposal and sale), which are the easiest to count.

How do I read the default example?

To sell $60,000 with a $1,500 deal size, you need 40 sales a month. At the example rates, that takes 134 proposals, 223 meetings, 556 qualified leads, 1,588 leads and 63,493 visitors. Today’s 60,000 visitors deliver about 38 sales (95% of the target): 88 leads short, and 6 reps are needed.

Which stage should I improve first?

The chart shows the extra sales from raising each stage by 2 percentage points with today’s traffic. Stages with low conversion usually gain the most per point. Also weigh the cost of each fix: improving lead qualification is often cheaper than redesigning a website.

What is a good conversion rate?

It varies widely by industry, channel and deal size. Websites often convert 1% to 5% of visitors into leads, and B2B close rates on proposals are often in the 20% to 40% range. Compare your funnel with its own history rather than with generic benchmarks.

How does the calculator handle long sales cycles?

It assumes all stages happen in the same month. If deals take 60 to 90 days, today’s leads close later: plan lead generation ahead and measure conversion by lead cohort (leads from the same month), not by the month of the sale.

Why does the cost per sale matter?

Because lead and sales costs must fit within your margin. If the cost per sale takes a large share of the deal size, growing the funnel may grow losses. Combine this page with the CAC and LTV calculator to see whether each customer pays back.

Sales funnel: how to calculate how many leads you need

A sales target only becomes a plan when it turns into numbers for each stage of the funnel: how many visitors, leads, qualified leads, meetings and proposals the team needs every month. The calculation works backwards, from the target to the top of the funnel.

From the target to the top

  1. Sales needed = monthly target ÷ average deal size, rounded up.
  2. Proposals = sales ÷ proposal-to-sale rate.
  3. Meetings = proposals ÷ meeting-to-proposal rate.
  4. Qualified leads = meetings ÷ qualified-to-meeting rate.
  5. Leads and visitors follow the same logic.

Example

A $60,000 target with a $1,500 deal size needs 40 sales. With a 30% close rate, that is 134 proposals; with 60% of meetings turning into proposals, 223 meetings; and so on up to the top.

Where to improve

Every stage multiplies the others. Improving a low-conversion stage usually brings more sales per point gained than improving one that already converts well. Before buying more traffic, check whether the leads you already have are being followed up and qualified properly.

Sales cycle

In B2B sales, a lead can take weeks or months to close. Plan the top of the funnel ahead of the target month, and track conversion by cohort (leads from the same month) to get reliable rates.
