QR Scan Funnel Calculator

Turn stage conversion rates into stage counts and an overall conversion rate, so you can see exactly where a QR campaign loses people. Everything recomputes from the rates you enter.

1. Enter stage rates

Formulas: scans = exposures × scan rate; landings = scans × landing rate; conversions = landings × conversion rate; overall conversion = conversions ÷ exposures × 100.

Find the Leak Before You Spend More

A campaign with weak results is rarely weak everywhere. Usually one stage leaks most of the audience — the code is not seen, the page does not load, or the offer does not convert. Measuring the funnel stage by stage tells you which fix pays: more visibility, a faster page, or a better offer. Spending more on exposure when the landing page drops 60% of scanners just buys more drop-offs.

A practical order of fixes

Fix load failures first (they waste every other improvement), then the scan rate (placement and call to action), then conversion (offer and page). Recompute after each fix with your measured rates to confirm the gain.

Frequently Asked Questions

What are the funnel stages?

Exposures (people who could see the code) → scans → successful landing-page loads → conversions (the action you want: purchase, signup, download). Each stage loses some people; the calculator shows exactly where.

Why separate landing success from conversion?

Because a scan that never loads the page is a technical failure, not a persuasion failure. Slow pages, dead links, and app-install walls lose scanners before your offer is even seen — fix the page before rewriting the offer.

What is a good overall conversion rate?

There is no universal benchmark — it depends on the offer, the audience, and the friction of the action. Compare against your own past campaigns and against the same funnel with one stage improved, not against an invented industry average.

How do I use this to improve a campaign?

Enter your measured rates, then raise one stage at a time and watch the overall conversion move. The stage with the biggest drop-off is usually the cheapest place to gain conversions.
