Conversion rate optimization usually costs $800 to $10,000 a month for ongoing work, according to WebFX's CRO pricing guide, with dedicated CRO agencies often charging $5,000 to $30,000+ a month. One-off Shopify audits from freelancers and small agencies start under $1,000, and some agencies work on a performance basis where you pay only when a lift is proven.
The right budget depends on your traffic. Below are the pricing models you will see, typical ranges, what should be included, and a simple way to check whether CRO will pay for itself at your revenue.
CRO pricing models: retainer, per test, audit and performance
Most CRO providers sell one of four models. Many mix them, for example an audit first and then a retainer.
- Monthly retainer. A fixed fee for an ongoing testing program: research, test design, development, QA and reporting. This is the most common model for agencies.
- Per test or per sprint. You pay for a set number of tests or a fixed block of work. It suits stores that want to try CRO before committing.
- Audit. A one-time review of your store with a ranked list of problems and fixes. You or your developer ship the changes.
- Performance-based. The fee depends on proven results. Spiralyze, for example, says clients pay no fee until it delivers the promised lift in conversions. Hybrid deals pair a lower base fee with a bonus tied to revenue gains.
Performance deals sound low-risk, but read the terms closely. You need to agree up front on how lift is measured, over what period, and what happens when a test wins on one metric and loses on another.
Pick the model that fits your stage
If you have never run an A/B test, an audit or a short sprint is the cheapest way to see how a provider thinks. If you already have steady traffic and a backlog of ideas, a retainer keeps tests running without gaps. Performance pricing suits stores with clean analytics, because disputes usually start with tracking.
Hourly consulting also exists. Freelance CRO experts on MentorCruise list about $60 an hour at the low end, $110 as typical and $200+ for senior people, as of November 2026.
Typical CRO price ranges
Published prices vary a lot, and most agencies only quote after a call. These ranges come from vendor pages and pricing roundups we checked, as of November 2026.
| Option | Typical price | Source |
|---|---|---|
| Freelance CRO expert, hourly | $60 to $200+ per hour | MentorCruise |
| Freelance Shopify CRO audit | $999 for a manual audit | Nikhil Sharma |
| Small-agency Shopify CRO audit | $799 to $1,499 | cro.media on the Shopify Partner Directory |
| Larger audit or optimization sprint | $3,000 to $25,000 per project | Personizely |
| Freelancer or consultant retainer | $2,000 to $8,000 per month | Personizely |
| Marketing agency with CRO add-on | From $1,800 per month (WebFX) | WebFX |
| Dedicated CRO agency | $5,000 to $30,000+ per month | Personizely |
| In-house CRO team | $10,000 to $25,000+ per month | Personizely |
Testing tools are often billed on top. WebFX puts CRO tools at $10 to $500 a month, and enterprise platforms can cost far more.
What drives the price up or down
A few factors explain most of the gap between a $2,000 and a $20,000 quote.
- Test volume. Each test needs research, design, development and QA. More tests a month means more hours.
- Who builds the tests. Some providers hand you designs and leave development to your team. Others code every variant and ship the winners, which costs more but saves your developer time.
- Seniority. A solo specialist with years of ecommerce tests costs more per hour than a junior, but often needs fewer hours to find a winner.
- Store complexity. Custom themes, many markets and currencies, subscriptions or headless builds all add QA time.
- Contract length. Longer commitments sometimes come with a lower monthly rate. Month-to-month terms give you an easy exit.
When you compare quotes, divide each monthly fee by the number of tests promised. Cost per launched test is a fairer comparison than the headline retainer.
Price alone tells you little. A $3,000 freelancer who ships two clean tests a month can beat a $15,000 agency that spends three months on research decks. Our guide on how to choose a CRO agency covers the questions to ask before you sign.
What is included in a CRO engagement
A full testing retainer should cover the whole loop, not just ideas. Byteex, a Shopify CRO agency, is a typical example: its ongoing service lists a funnel audit, hypothesis work, A/B testing, copywriting, Shopify development, monthly reporting and quarterly reviews, at 2 to 4 tests a month.
Before you sign, check these items in writing:
- Research. Analytics review, heatmaps, session recordings and customer surveys.
- Test volume. How many tests launch each month, not how many are "planned".
- Design and development. Who builds the variants and who ships the winners to your live theme.
- QA. Testing on mobile and across browsers before launch.
- Tool costs. Whether the testing tool is included or billed to you.
- Reporting. Results per test, including losers, with the metric and confidence level.
- Contract terms. Minimum term, notice period and who owns the test data.
Insist on losing tests being reported. Many tests do not win, as our A/B test win rate research shows, and losers teach you what not to ship.
The same idea can win on one store and lose on another. Dave Diederen saw +3.16% revenue per visitor (+$139,029/month est.) from a checkout countdown timer, yet a different checkout countdown test lost 7.1% RPV. Kasper Dolk went the other way and removed a checkout countdown timer for +26.18% RPV, est. +€150k/month. Part of what you pay for is the testing that tells you which result applies to your store.

Is CRO worth it at my revenue?
CRO pays off when a realistic lift on your current revenue covers the fee. A quick check: divide the monthly fee by your monthly revenue. That is the revenue lift you need just to break even, before product costs.
Worked example. A store doing $100,000 a month pays a $5,000 retainer. $5,000 / $100,000 = 5%, so the program must add 5% to revenue just to cover the fee. At a 50% gross margin, the store needs about a 10% revenue lift to break even on profit. The same retainer at $1,000,000 a month needs only a 0.5% revenue lift.
That is why most agencies target larger stores. Traffic matters too: smaller stores need longer tests to reach a clear result. Use our A/B test sample size calculator to see how long a test would take on your traffic.
At scale, single wins can cover a year of fees. Oliver Kenyon of Conversionwise tested a mega menu with category descriptions and a testimonial for +$151,192/month. Milos, who does CRO for $200k to $1M a month stores, rebuilt a best-seller product page for +128% RPV (+$14,867/month).
Losses can be just as large, which is the case for testing over guessing. Milos also saw a "Buy 2 Get 1 Free" offer lose 52.38% RPV (-$104,679/month). A test caught that before it went live for every visitor. Our losing A/B tests research has more examples.

A rough guide by stage:
- Under about $50,000 a month: a one-time audit or a few hours of consulting usually makes more sense than a retainer. Ship the clear fixes and check your numbers against our Shopify conversion rate benchmarks.
- Mid-size stores: a freelancer or small agency running a few tests a month keeps the break-even lift realistic.
- Larger stores: a full agency program can be easier to justify, because a small percentage lift is a large dollar amount.

How much do CRO freelancers charge?
Freelance CRO experts on MentorCruise list about $60 an hour at the low end, around $110 as typical and $200+ for senior specialists. Freelancer retainers often run $2,000 to $8,000 a month.
Is performance-based CRO pricing a good deal?
It can be, because you pay only for proven lift. Agree in writing on the metric, the measurement period and how results are attributed before you start, since these terms decide what you end up paying.
Is CRO worth it for a small store?
Divide the monthly fee by your monthly revenue to get the lift needed to break even. For smaller stores that number is often too high for a retainer, so a one-time audit or a few hours of consulting is usually the better start.
