How to calculate it
Subtract previous conversion rate from current conversion rate, divide the difference by the absolute starting value, and multiply by 100. A negative sign means a decrease.
- Insert the values in the formula, perform the division first, and round only the final answer.
- A positive answer indicates growth and a negative answer indicates a reduction. The percentage is measured against the starting value.
Applied example
When previous conversion rate moves from 3.5 conversions to 4.13 conversions, the percentage change is 18%.
Subtract previous conversion rate from current conversion rate, divide the difference by the absolute starting value, and multiply by 100. A negative sign means a decrease. A positive answer indicates growth and a negative answer indicates a reduction. The percentage is measured against the starting value.
Practical use
Find the percentage of visitors who complete an action.
For website conversion, use “previous conversion rate” as the reference. It must represent the full set or the starting point of the comparison.
Checks that matter
- Use users or sessions consistently and define the conversion event precisely.
- Do not treat the absolute difference as a percentage; divide it by the starting value first.
- Keep full precision during the calculation and round only the final answer to match the accuracy of the source data.
Frequently asked questions
What is the correct reference value?
For website conversion, use “previous conversion rate” as the reference. It must represent the full set or the starting point of the comparison.
Can the answer be greater than 100%?
Yes. This happens when the part exceeds the total or the final value is more than double the starting value.
How many decimal places should I use?
Keep full precision during the calculation and round only the final answer to match the accuracy of the source data.
