Conversion Uplift Impact Calculator

Estimate the upside from a conversion-rate uplift. Enter traffic, baseline conversion rate, expected lift, and average revenue per conversion to forecast incremental revenue, payback period, and ROI over your measurement window.

Examples

  • 60,000 visitors, 2.8% conversion rate, 18% uplift, $145 order value, $12,500 implementation cost, 6-month window ⇒ Additional conversions/month: 302. Incremental revenue/month: $43,790.00. Payback time: 0.3 months. 6-month ROI: 1,006.2%.
  • 18,000 visitors, 3.5% conversion rate, 7% uplift, $210 order value, $6,000 implementation cost, 4-month window ⇒ Additional conversions/month: 44. Incremental revenue/month: $9,240.00. Payback time: 0.6 months. 4-month ROI: 516.0%.

FAQ

What if my uplift is an absolute percentage point change?

Convert it to a relative lift by dividing the expected new rate by the current rate. For example, going from 2% to 2.4% is a 20% uplift.

How should I treat subscription products?

Multiply the average order value by customer lifetime value or the first-year revenue you attribute to a conversion to better reflect recurring revenue.

Can I include testing platform fees?

Yes. Add A/B testing or analytics tool costs into the implementation cost field so the payback and ROI include them.

Additional Information

  • Relative uplift multiplies the baseline conversion rate (e.g., 20% uplift on 3% becomes 3.6%).
  • Incremental revenue assumes every extra conversion produces the average order value you entered.
  • ROI aggregates incremental revenue across the full analysis window before subtracting implementation cost.
