Website Conversion Calculator

Work out what proportion of your visitors convert — then see what reaching a realistic target rate would actually be worth in extra enquiries.

Your numbers Any period
Sessions or users per month. Be consistent between periods.
Enquiries, bookings or purchases per month.
Optional. What you think the site could realistically reach.

Method: Conversion rate = Conversions ÷ Visitors × 100. Extra conversions at target = Visitors × (target % − current %) ÷ 100.

How this calculator works

Enter monthly visitors and conversions to get your current rate. Add a target rate and the calculator shows how many extra conversions a month that would produce from the traffic you already have.

The formula

Conversion rate = Conversions ÷ Visitors × 100. Extra conversions at target = Visitors × (target % − current %) ÷ 100.

Worked example

12,000 visitors and 180 enquiries is a 1.5% conversion rate. Reaching 2.5% on the same traffic would produce 300 enquiries — 120 more a month without buying a single extra visit.

How to read your result

The uplift figure is arithmetic on your own numbers, not a prediction. It exists to show the size of the prize: for most sites, improving conversion is considerably cheaper than buying proportionally more traffic.

Questions

Whatever you actually want — enquiries, bookings, purchases or calls. Counting newsletter sign-ups alongside sales will flatter the rate and tell you nothing useful.

Look at your own best-performing pages rather than a published average. If one landing page converts at 4%, that is evidence of what your traffic and offer can do.

Usually because the extra traffic is less qualified. Segment by channel before concluding the site got worse.
