Funnel conversion rate is the share of people entering the funnel who reach the final stage: customers ÷ visitors × 100. With 10,000 visitors and 50 customers it is 0.5%. Each step also has its own rate, such as leads ÷ visitors, and the lowest one shows where the funnel leaks most.

About this tool

Marketers, growth leads and founders track funnels in four counts: visitors, leads, qualified leads and paying customers. A single overall figure hides where people are lost, so this calculator divides each stage by the one before it, gives the overall rate from top to bottom, counts how many people dropped at every step and names the weakest step. A bar chart shows how much of the original traffic is still left at each stage, and the table lists counts, step rates and drop-offs side by side. Use counts from the same period and the same cohort: mixing this month's leads with last month's visitors gives rates that look precise but describe no real group of people. The tool assumes a strict sequence, so a later stage can never be larger than the one before it.

How to use it

  1. Enter visitors

    Type the number of people who entered the top of the funnel in your chosen period.

  2. Add leads and qualified leads

    Enter how many signed up, then how many of those sales accepted or moved to a demo.

  3. Add customers

    Enter how many qualified leads paid. Results and the chart update as you type.

  4. Read the weakest step

    Compare the three step rates and the drop-off column in the table to see where to work first.

Examples

200,000 visitors, 10,000 sales

Visitors
200000
Leads
50000
Qualified leads
20000
Customers
10000

Result Overall funnel conversion rate: 5%
Visitor to lead: 25%
Lead to qualified: 40%
Qualified to customer: 50%
Weakest step: Visitors → leads (25%)
Visitors per customer: 20

  1. Visitors → leads: 50000 ÷ 200000 × 100 = 25%
  2. Leads → qualified leads: 20000 ÷ 50000 × 100 = 40%
  3. Qualified leads → customers: 10000 ÷ 20000 × 100 = 50%
  4. Overall: 10000 ÷ 200000 × 100 = 5%

A shop where a quarter of visitors sign up, 40% of those qualify and half of the qualified buy ends at 5% overall.

10,000 visitors to 50 customers

Visitors
10000
Leads
500
Qualified leads
200
Customers
50

Result Overall funnel conversion rate: 0.5%
Visitor to lead: 5%
Lead to qualified: 40%
Qualified to customer: 25%
Weakest step: Visitors → leads (5%)
Visitors per customer: 200

  1. Visitors → leads: 500 ÷ 10000 × 100 = 5%
  2. Leads → qualified leads: 200 ÷ 500 × 100 = 40%
  3. Qualified leads → customers: 50 ÷ 200 × 100 = 25%
  4. Overall: 50 ÷ 10000 × 100 = 0.5%

Only 5% of visitors become leads, so the top step is where this funnel leaks most.

How it is calculated

step rate = stage(n) ÷ stage(n−1) × 100; overall rate = customers ÷ visitors × 100

stage(n)
count of people at a stage
stage(n−1)
count at the stage directly before it
overall rate
share of visitors who became customers

Each step rate is a simple ratio of two neighbouring stages. The overall rate equals the product of the three step rates: 5% × 40% × 25% = 0.5%. Because of that, doubling any one step doubles the overall result, which is why the lowest step is flagged. Dropped counts are the difference between neighbouring stages, and visitors per customer is the inverse of the overall rate.

When not to use it

  • Skip it for funnels where people can enter at a middle stage, such as sales-sourced leads.
  • Do not use it to compare channels with very different traffic volumes without checking sample size.
  • It is not a forecast of future conversions; it describes one past period.

Common mistakes

  • Counting sessions at the top and unique people at the bottom of the funnel.
  • Mixing cohorts from different months, so a stage looks larger than it should.
  • Judging a step rate from a handful of conversions, where one sale swings it by many points.
  • Comparing your overall rate with an industry figure that defines the stages differently.

Frequently asked questions

What is a good funnel conversion rate?

It depends on price and sales cycle. Low-cost ecommerce often sees 1–4% of visitors buy, while B2B funnels with a sales team often end below 1% of visitors. Compare against your own history and against benchmarks that define stages the same way.

Why is the overall rate so much lower than each step?

The overall rate multiplies the step rates together. Three steps of 50% each give only 12.5% overall, so even healthy steps compound into a small final figure.

Which step should I improve first?

Usually the one with the lowest step rate, shown as the weakest step, since a relative lift there moves the overall rate by the same factor as any other step but often has the most room. Also weigh how many people drop there and how costly a fix is.

Why does the tool reject more leads than visitors?

The calculation assumes each stage is a subset of the one before. If leads exceed visitors, your counts come from different periods, different tracking or a source that skips the top stage. Fix the data so the stages describe the same group.

Should I count sessions or users at the top?

Use unique users when your later stages count people, which they almost always do. Sessions inflate the top of the funnel and make the visitor-to-lead rate look worse than it is.

What does visitors per customer tell me?

It is the inverse of the overall rate: how many visitors you need to win one customer. At 0.5% that is 200 visitors, which helps when you estimate how much traffic a revenue target needs.
