pm_calculate_conversionConversion Rate
The percentage of users who complete a step in your funnel.
When to use this
You have a multi-step user flow (signup, checkout, onboarding, demo booking) and you want to know which step is leaking. Conversion is most useful by stage, not as a single overall number. Track it weekly for products with short cycles, monthly for longer ones.
Limits
Define the desired action and eligible population first. Small samples produce uncertain rates, but there is no universal minimum count for every funnel. Segment where customer intent differs and keep the blended number for the overall view.
Inputs
- Step definitions: every distinct user action in order. "Visit homepage" is a step. "Add to cart" is a step. "Complete checkout" is the goal.
- Users entering each step: distinct users, not sessions, unless your product is genuinely session-based.
- Time window: a fixed period. Mixing a 7-day cohort with a 30-day cohort breaks the math.
The math
Conversion = (users completing step / users entering step) x 100That's per step. The overall conversion is the product of every stage rate.
Overall = stage_1 x stage_2 x ... x stage_NCompare absolute losses, relative drop-off, business impact, and the feasibility of improving each stage.
A worked example
An e-commerce funnel for 10,000 visitors over one week:
| Stage | Users | Stage rate |
|---|---|---|
| Visit | 10,000 | -- |
| View product | 4,000 | 40% |
| Add to cart | 1,200 | 30% of viewers |
| Start checkout | 360 | 30% of cart |
| Complete | 252 | 70% of checkout |
Overall: 252 / 10,000 = 2.52%.
Cart-to-checkout loses 70%, tied with view-to-cart for the largest relative drop. Visit-to-view loses the most users in absolute terms: 6,000. If cart-to-checkout improved from 30% to 45% while other rates stayed fixed, overall conversion would be 3.78%, a 50% relative gain. The same 15-point improvement at visit-to-view would produce 3.465%, a 37.5% relative gain. These are scenarios, not forecasts.
In PM Toolkit
The calculator supports conversion counts and funnel-stage analysis. Review both the overall result and the steps behind it; the largest drop alone does not establish which change will have the best return.
Common mistakes
- Tracking only overall conversion and missing changes within stages.
- Comparing with an industry figure that uses a different action, denominator, or channel mix.
- Giving recent users too little time to complete a long sales cycle.
- Treating seasonal or day-of-week variation as an effect of a product change.
Benchmarks (illustrative)
Unbounce's 2024 report reports a 6.6% all-industry median from its landing-page data. The study covers about 41,000 landing pages and 464 million pageviews. It is not a universal website-purchase, trial-to-paid, or demo-to-deal benchmark. See the industry comparison for source scope and industry figures.
