The short version: The Remarkable’s 2026 planning range for a CRO retainer is $4,000 to $15,000 a month. A full single-funnel program plans at $6,000 to $10,000. Multi-funnel work can reach $10,000 to $15,000. Per-experiment work ranges from $1,500 to $5,000. Performance deals take a share of measured lift. These are internal estimates, not market averages.
The headline number first: a full single-funnel program plans at $6,000 to $10,000 a month. A multi-funnel program can reach $10,000 to $15,000. The rest separates three billing models from the engagement formats that set the final scope.
Disclosure: we run a growth agency with a conversion optimization practice, so we price this work. The models are specific so you can compare any quote, including ours, on equal terms.
How Much Does a CRO Agency Cost in 2026?
The Remarkable’s 2026 planning range for a CRO retainer is $4,000 to $15,000 a month. A focused single-funnel scope sits near $4,000 to $6,000. A full single-funnel program plans at $6,000 to $10,000. Multi-funnel work with research, design, and development can reach $10,000 to $15,000.
Per-experiment work ranges from $1,500 to $5,000 in our scope reviews. Our one-time audit range is $2,000 to $7,500. These figures come from proposals and scope reviews, not a published market-wide survey. Compare quotes by included research, design, development, and test volume.
Three core pricing models determine how the agency gets paid. Retainers fund ongoing work. Per-experiment pricing pays for each test. Performance pricing pays a share of measured lift.
| Core pricing model | Typical cost | What it rewards |
|---|---|---|
| Monthly retainer | $4,000 to $15,000/mo | Steady research and testing |
| Per-experiment | $1,500 to $5,000/test | Tests shipped |
| Performance-based | % of incremental lift | Measured wins |
Engagement format determines what the fee covers. An audit is a one-time diagnosis, not a fourth pricing model. Single-funnel and multi-funnel retainers use the same billing model. They require different amounts of research, design, and development.
| Engagement format | Planning range | Scope |
|---|---|---|
| Focused single funnel | $4,000 to $6,000/mo | One funnel, narrower support |
| Full single-funnel program | $6,000 to $10,000/mo | Research, design, and development |
| Multi-funnel program | $10,000 to $15,000/mo | Several funnels, full support |
| One-time audit | $2,000 to $7,500 | Diagnosis before ongoing work |
Retainers suit ongoing CRO programs because research and testing continue. A measured gain can add value each month while traffic and economics hold. It does not automatically compound without further growth or improvements.
What Does Each CRO Pricing Model Reward?
Each model creates a different incentive. A retainer funds steady research and testing. Per-experiment pricing rewards test volume. Performance pricing rewards measured wins but can create disputes about lift. Choose the incentive you want the team to follow.
The retainer is the cleanest alignment for most companies. It funds research, which is where good hypotheses come from, regardless of whether any single test wins. That stability is the point, because plenty of tests are supposed to lose.
- Retainer: pays for a program. Best when you want sustained learning, not a one-off bump.
- Per-experiment: pays per test shipped. Fine for low volume, but can reward quantity over rigor.
- Performance-based: pays on lift. Aligned in theory, messy in practice, covered below.
Is Performance-Based CRO Pricing Worth It?
Performance pricing can work, but measurement makes it difficult. The agency earns more when a test wins. Proving incremental lift still needs a valid control and enough time. Without both, the percentage rests on a weak estimate.
Attribution disputes follow. Was the lift from the test, a seasonal swing, or a separate campaign that ran the same week? When real money rides on the answer, both sides argue, and the relationship sours. The HBR account of the surprising power of online experiments describes one Microsoft test that lifted Bing revenue 12%. That clear a read needs disciplined experiment infrastructure, which most companies do not have.
Performance-based pricing can work with mature analytics, a holdout discipline, and a partner you already trust. For everyone else, a retainer that funds research and testing regardless of any single outcome is the safer buy.

Three factors set the price: funnel count, research depth, and variant ownership. More funnels, deeper research, and agency-side development push toward the top. Removing work lowers the quote, but it also changes the program.
The research line is where cheap quotes hide their cut. Research takes hours, so a low retainer often skips it and goes straight to testing untested ideas. You pay for motion, not learning.
Development is the other quiet driver. An agency that designs and builds its own variants ships on its own schedule. One that hands you tickets is cheaper because the cost moved to your engineers. The test still has to get built; the bill just lands in a different budget.
- Funnel count: one funnel is cheap; several multiplies the research and design load.
- Research depth: interviews, recordings, and surveys cost hours and lift the price honestly.
- In-house dev: building variants in-house costs more but protects velocity.
- Traffic and complexity: higher volume and intricate funnels need more senior time.
What Should You Budget for CRO?
Our full single-funnel planning range is $6,000 to $10,000 a month with research, design, and development included. Multi-funnel programs can reach $10,000 to $15,000. Per-experiment pricing can fit low or irregular volume. For a quote far below $4,000, ask whether research or development sits outside the scope.
Price the program against a measured opportunity, not a vague plateau. A $300,000 monthly funnel can justify testing when evidence shows a material conversion gap. The cost of waiting may exceed the retainer, but only when traffic, margin, and testable upside support that conclusion.
