Use your real numbers
trckable shows your conversion rate and the revenue behind each source, so you can fill this in from data, not a guess. Start free, or check a test's result with the A/B test calculator.
A small change in conversion rate is worth more than it looks, because it applies to every visitor you already pay to get. This calculator turns a rate into money so you can decide whether a change is worth the effort.
How it is calculated
Customers a month are visitors times conversion rate. The extra customers are the visitors times the difference between the target rate and today's.
- One-off sales. Extra revenue a month is the extra customers times the average order value. The year is twelve months of that.
- Subscriptions. Each month's extra customers pay a monthly fee, and some cancel every month. The calculator follows each month's new customers through the next twelve months, with the churn you enter, and adds up what they pay. That is the extra revenue in the first year, which is lower than twelve times one month's.
The chart compares the twelve-month revenue from new customers at today's rate and at the target. It counts only customers won in these twelve months, not those you already have.
Where the inputs come from
- Visitors a month: the unique visitors of the page or site in question.
- Conversion rate: customers divided by visitors, from the same period. See conversion rate.
- Order value or monthly fee: use revenue after tax, the figure you keep.
- Churn: the share of subscribers who cancel in a month.
Using the result honestly
The sentence at the top of the result assumes the new rate holds and that the extra customers are as good as the ones you have. In practice an improvement often brings in slightly less committed customers, and a rate measured over a short period can be a lucky stretch. Treat the number as an upper bound for planning, and confirm a change with a proper test before you count the money.
Questions
- Why is the subscription figure less than twelve times a month?
- Customers won in later months pay for fewer months of the year, and some cancel. The calculator counts only what is paid within the twelve months.
- Does it include customers I already have?
- No. It shows the extra revenue from the change only, so you can weigh it against the work.
- Is my data sent anywhere?
- No. The calculation runs in your browser. The share link puts the numbers in the address, so anyone with the link sees them; it contains no personal data.
