How the calculation works
The calculator uses three steps, all based on your inputs:
- Conversions = monthly visitors × conversion rate
- Monthly revenue = conversions × average order value
- Annual gain = (target revenue − current revenue) × 12
A worked example
A site with 45,000 monthly visitors converting at 2% earns 900 orders a month. At a $150 average order value that is $135,000. Lift the rate to 3% and it becomes 1,350 orders, or $202,500: an extra $67,500 a month and $810,000 over a year.
Before running a test, check it can detect the lift you care about with the sample size calculator.
Questions, answered
How do you calculate the ROI of an A/B test?
Multiply monthly visitors by the change in conversion rate to get extra conversions, then multiply by average order value. That gives the extra monthly revenue; multiply by 12 for a year. Compare it with what the test cost to run.
What is a good conversion rate?
It depends on industry, traffic source, and price. Many ecommerce sites sit between 1% and 4%, while B2B lead forms vary widely. Your own current rate is the most useful baseline.
Why does a small conversion lift make such a big difference?
Revenue scales linearly with conversion rate. Going from 2% to 3% is a one-point change but a 50% increase in conversions, and that increase repeats every month.
Is this a forecast?
No. It is a direct calculation from the values you enter. Real results depend on whether a lift holds, seasonality, and traffic changes.
How long would a test need to run to detect this lift?
That depends on traffic and the size of the change. Use the sample size calculator to estimate visitors and duration.
