Ecommerce conversion rate calculator — your rate against the 2026 benchmarks

Last reviewed: 28 July 2026. Every benchmark this tool compares against is quoted with its publisher, its measurement basis and the date it was read; two of the four are rolling datasets that change monthly. The full argument — samples, verbatim definitions, industry and device splits — lives in the companion guide.

Prefilled to the average Shopify store — Littledata's 2023 benchmark median of 1.4%, at their US$85 Shopify average order value. Not Mtrix data. Replace every field with your own numbers over one period.

Session-based

1.40%

orders ÷ sessions × 100

350 orders ÷ 25,000 sessions. This is the form Shopify's admin and IRP Commerce use.

At or above the median — below the top 20%

Below < 1.4%
Median+ 1.4–3.2%
Top 20% > 3.2%
Top 10% > 4.7%

Shopify stores · Littledata 2023 percentiles, not averages — and the only publisher here that reports any

Visitor-based

—

orders ÷ unique visitors × 100

Add your unique visitors to compare against Dynamic Yield's figure. Without it the comparison is between two different measurements.

Revenue: $29,750
Revenue per session: $1.19
Value of 0.1 pp of conversion rate: $2,125

Arithmetic on the numbers you typed, not a forecast and not a promise: a tenth of a point on 25,000 sessions is 25 more orders at your own average order value. Whether you can move it a tenth of a point is a different question, and no benchmark answers it.

Your rate against the four published figures

each on its own denominator

Your conversion rate compared with each published benchmark, on that benchmark's own measurement basis
Published	Publisher	Basis	Period	You	Difference
1.4%	Littledata	Sessions denominator not published	2023	1.40%	0.00 pp
1.6%	Statista, via Shopify	Visits	Q3 2025	1.40%	−0.20 pp

A difference is not a verdict. Each of these four measures something slightly different — read the basis column, then the section above on why they disagree.

Nothing you type is sent anywhere — it is all computed in your browser.

There is no single average ecommerce conversion rate to check yourself against — so this calculator computes yours both ways and compares like for like. The four most-cited published figures run from 1.4% to 2.74%, and they don't measure the same thing: three divide by sessions or visits, one by unique people. Your session-based rate is only ever placed against the session-based benchmarks, your visitor-based rate against the visitor-based one. Why the published numbers disagree — denominator, sample, period, device and industry mix — is the guide's job. This page's job is your number.

The calculator

Two fields give you the session-based rate — the number already in your Shopify admin, which computes it free. What your admin doesn't do is place it on the right basis: add unique visitors and you get the visitor-based form too, each compared only against the benchmarks that measure it the same way. Add average order value and it returns revenue and revenue per session — arithmetic on the numbers you typed, labelled as arithmetic, not a promise.

The four benchmarks it compares against

Condensed from the guide's spine table; every cell is verbatim from the shared data module, and a figure never renders without its basis and its date.

The four published ecommerce conversion rates this calculator compares against
Figure	Publisher	Basis	Period
1.4%	Littledata	Sessions (denominator not published)	2023
1.6%	Statista, via Shopify	Visits	Q3 2025
2.03%	IRP Commerce	Sessions	June 2026
2.74%	Dynamic Yield	Visitors	rolling 12mo, read 26 Jul 2026

Samples, verbatim definitions, the industry spread and the device split are in the guide — this table exists so no result on this page travels without its scope.

Which number to compare yourself to

Match the denominator. Your admin's rate is session-based, so hold it against Littledata's 1.4% (Shopify stores, 2023) or IRP's 2.03% (UK market, June 2026) — never against Dynamic Yield's 2.74%, which counts unique people and always reads higher. The calculator enforces this: its Dynamic Yield row stays empty until you supply visitors, and says so, because a number there would be wrong before it was useful.

Then prefer percentiles to averages. Littledata's 2023 dataset is the only one in the set that publishes them: median Shopify store 1.4%, best 20% above 3.2%, best 10% above 4.7%. The distance from median to top decile inside that one dataset is wider than the distance between any two published averages — so the verdict band under your result uses those percentiles, carries a permanent "Shopify stores · Littledata 2023" chip, and no other benchmark gets a band. The step before the order has the same denominator problem, and the add-to-cart rate calculator covers it.

FAQ

What is a good ecommerce conversion rate?

One that clears a percentile, not "the average": Littledata's 2023 Shopify dataset puts the median at 1.4%, the best 20% above 3.2% and the best 10% above 4.7% — the bands this calculator's verdict uses. The published averages themselves span 1.4%–2.74% on different denominators, and what you sell moves the bar more than either; the guide carries the full industry table.

How do you calculate ecommerce conversion rate?

Session-based: orders ÷ sessions × 100, with "online store sessions" and orders pulled from your admin for the same period. Visitor-based: orders ÷ unique visitors × 100. This calculator returns both and never mixes them — and whenever you write the number down, say which form it is.

What's the difference between a session-based and a visitor-based conversion rate?

The denominator: visits versus people. One shopper who visits three times and buys once is 33.33% on a session basis and 100% on a visitor basis — so the visitor form always reads higher. That one difference explains most of the gap between Littledata's 1.4% and Dynamic Yield's 2.74% before sample or period differences even start.

Why is my Shopify conversion rate lower than the average I read?

Check the average's basis before you blame the store. Your admin number is session-based; the higher figures that get quoted are usually visitor-based or drawn from enterprise panels. The closest published like-for-like is Littledata's 1.4% Shopify median — most stores sit nearer it than the headlines. Then split by device before deciding anything; the guide covers the mobile gap and what to do about it.
