Conversion Rate Lift Calculator
Turn a conversion-rate improvement into revenue.
How the conversion rate lift calculator works
A conversion-rate improvement sounds abstract until it is priced. A move from 2.0% to 2.4% is a 20% relative lift, and on real traffic it is a specific number of extra orders and dollars every month.
Enter your traffic, your baseline and target rates, and your average order value. The calculator separates the absolute lift (in percentage points) from the relative lift (against your baseline), then prices both.
This is the number that justifies conversion work. A test that lifts conversion by half a point can pay for a quarter of optimisation in a single month.
The formula
How this is calculated
The absolute lift is the difference in percentage points; the relative lift expresses it against your baseline. Extra orders are visitors times the absolute lift, and extra revenue multiplies that by AOV.
Worked example
A 0.4-point lift on 40,000 visitors at $65 AOV adds about $10,400 a month.
Frequently asked questions
What is the difference between absolute and relative lift?
Absolute lift is the change in percentage points (2.0% to 2.4% is 0.4 points). Relative lift expresses that against the baseline (0.4 / 2.0 is a 20% relative lift). Tools and reports usually quote relative lift.
How large a lift is realistic from one change?
Single high-impact changes often produce low-single-digit to low-double-digit relative lifts. Large lifts usually come from fixing a specific, severe friction point rather than broad tweaks.
