Paid landing page test
Model whether a better headline, offer, or form layout justifies the design and media cost before you launch an A/B test.
Put a dollar figure on CRO before you run the test. Compare 0.5 to 3 percentage-point lifts on your traffic and AOV.

Conversion rate lift measures the change between your current conversion rate and a higher target rate. A move from 2% to 3% is only 1 percentage point of absolute lift, but it is a 50% relative lift. That difference matters because even small absolute gains can create large revenue changes when multiplied by meaningful traffic and average order value. The calculator uses your monthly visitors, current conversion rate, average order value, and gross margin to estimate the added conversions, revenue, gross profit, and optional ROAS impact from each scenario. As a rough 2026 benchmark, IRP Commerce reported a 2.03% average ecommerce conversion rate in June 2026, while Littledata's Shopify benchmark still put 3.2% or better in the top 20% of stores. That makes a half-point or one-point lift financially meaningful for many teams even before they reach best-in-class performance.
E-commerce store profile: monthly visitors 200,000, current conversion rate 2.1%, target conversion rate 2.8%, and average order value $65. Relative lift = ((2.8 - 2.1) / 2.1) x 100 = 33.3%. Current monthly conversions = 4,200. Target monthly conversions = 5,600. Additional conversions = 1,400. Monthly revenue lift = 1,400 x $65 = $91,000. Annual revenue lift = $91,000 x 12 = $1,092,000. A 0.7 percentage-point improvement creates a seven-figure annual upside without buying more traffic.

Estimate how much a cart or checkout fix is worth when engineering asks for revenue impact instead of a generic CRO argument.
Translate a small conversion improvement into monthly revenue, annual lift, and gross-profit upside for planning decks and budget reviews.
It depends on the business model and channel mix. IRP Commerce reported a 2.03% ecommerce average in June 2026, and Littledata's Shopify benchmark says stores above 3.2% sit in the top 20%. For lead generation pages, a healthy rate is often higher because the conversion action is lighter than a purchase.
Most testing programs do not lift conversion every week, but the winners can still matter. A sustained CRO program may produce a handful of meaningful wins each quarter, and even a 0.5 to 1.0 percentage-point gain can create a large revenue change when traffic volume is high.
Absolute lift is the raw difference: from 2% to 3% is 1 percentage point of absolute lift. Relative lift is the percentage change: from 2% to 3% is a 50% relative lift. Relative lift is useful for comparing results across tests with different baselines.
No. This calculator shows the projected impact of a confirmed conversion-rate change. Use an A/B test sample-size or significance calculator before you treat a measured lift as real business upside.
Start with your last 30 to 90 days of real analytics data. If you do not have that yet, model a conservative baseline near your channel benchmark, then rerun the calculation once you have enough traffic and completed conversions to trust your own number.
Small lifts matter fastest when traffic, order value, or gross margin are already meaningful. A half-point gain on a low-traffic page may be minor, but the same gain on a high-volume paid landing page can change monthly revenue and ROAS enough to fund more testing.
Both matter, but conversion improvements compound across all future traffic. If you buy more traffic before fixing obvious leaks in the funnel, you often pay to send more visitors into the same weak experience.
Each additional point of conversion-rate improvement is usually harder to earn than the last. Once you have already removed the obvious friction, future gains depend on tighter positioning, stronger segmentation, better offers, or more precise experiment design.
