VWO Pricing (2026): What Growth, Pro & Enterprise Actually Cost

Last updated: August 13, 2026 · Originally published: May 12, 2025

VWO is partially transparent about pricing. It publishes a Growth plan from $314/month and a Pro plan from $972/month (both billed annually) plus a free Starter tier, but Growth, Pro, and Enterprise all route through a demo and custom quote, and the MTU allocation behind each price varies by deal. Third-party purchase data puts the median VWO contract at $16,660/year, which tells you most buyers do not pay the list price.

Pricing at a glance (2026)

Plan	Reported price	Who it targets	What you get
Starter	Free	Small sites validating testing	Basic A/B and split URL testing, limited variations and metrics, capped data retention
Growth	$314/month billed annually	Small teams running a real program	Unlimited experiments, unlimited variations and metrics, enhanced targeting, VWO Insights (heatmaps, recordings, surveys)
Pro	$972/month billed annually	Mid-market, multi-module	Multivariate testing, advanced targeting, AI features, deeper analytics
Enterprise	Custom, reported from ~$1,265/month billed annually	Large orgs, 500K+ MTUs	All modules, full API access, SSO, dedicated CSM, 24x7 support
Median actual contract	$16,660/year	,	Across 93 verified purchases (CostBench)

A caveat worth reading. Sources disagree on how many MTUs each tier includes, some report Growth's $314 covering 10,000 MTUs, others 50,000. That is not sloppy reporting so much as a symptom of quote-based pricing: the MTU allocation is part of the negotiation. Treat VWO's pricing page as the only authoritative source and confirm your MTU allowance in writing.

Want pricing you can read without a demo? Try Stellar free — Sandbox $0 for 5,000 MTU; Plus $29/mo (annual) for 25k MTU; Pro $99/mo (annual) for 50k MTU then $2 per extra 1k; Scale $399/mo (annual) for 250k MTU then $1.50 per extra 1k — all published on the site.

How VWO's MTU model works

VWO prices on Monthly Tracked Users, unique visitors who enter one of your experiments in a calendar month. Two consequences follow, and both catch buyers out:

1. Cost scales with tested traffic, not test count. Running 20 experiments on a low-traffic pricing page can cost less than one experiment on your homepage. This is good news if you test deliberately and bad news if you want sitewide personalization.
2. Traffic spikes become billing events. Exceeding your MTU quota means buying more MTUs, and VWO does not publish overage rates. Independent trackers suggest planning for 120–130% of expected MTU volume to avoid a mid-year tier upgrade.

If your traffic is seasonal, ecommerce peaks, campaign bursts, PR spikes, model your worst month, not your average one.

Estimate your VWO cost in three steps

1. Count testable traffic. Monthly unique visitors to the pages you actually plan to test. Not sitewide sessions, not pageviews.
2. Pick the tier by capability, then check the MTU fit. Growth if you need unlimited experiments and Insights; Pro if you need multivariate testing or advanced targeting. Then confirm the MTU allowance at that price.
3. Add headroom and services. Budget 20–30% MTU headroom, plus onboarding time. VWO is more self-serve than Optimizely, so implementation costs are typically lower, but not zero.

Does VWO deliver value for the price?

For sites with moderate traffic and high-value conversions, yes, a 2% lift on a $500 average order value pays for a Growth plan quickly. The maths turn against VWO in two situations:

• High traffic, low conversion value. MTU pricing charges you for the visitors you test, regardless of whether those visitors are worth much. Content and media sites feel this most.
• Speed-sensitive sites. VWO's script loads from VWO's servers, and client-side testing tags can delay rendering. If Core Web Vitals are a ranking or revenue concern, weigh script weight alongside licence cost. See lightweight A/B testing for the performance-first framing.

VWO vs Optimizely vs Stellar

Dimension	VWO	Optimizely	Stellar
Published entry price	$314/mo (Growth, annual)	None, quote only	$0 up to 5k MTU (Sandbox)
Free tier	Yes (Starter, capped)	Rollouts only, not web testing	Yes, for A/B testing
Reported entry cost	~$3,800/yr	~$36,000/yr	$0, or $99/mo Pro
Median contract	$16,660/yr	~$78,000/yr	,
Billing	Annual for paid tiers	Annual / multi-year	Monthly or annual
Pricing model	MTU tiers	MTU tiers	MTU-based, $2/mo per extra 1k
Sales call to buy	Demo required for paid tiers	Always	No
Script	External, heavier tag	Enterprise tag	5.4KB async

VWO sits in the middle: cheaper and more transparent than Optimizely, more expensive and more sales-gated than tools that publish everything. Whether that is the right trade depends on whether you need VWO Insights and Personalize alongside testing, or just want to run experiments.

Trialling VWO

VWO offers a 30-day free trial of paid features alongside the permanent free Starter tier, plus demos and consultations. Two things worth doing during a trial:

• Measure the performance hit. Run Lighthouse or Core Web Vitals before and during, with a test live. This is the number you cannot get from a sales call.
• Watch MTU burn. Check how fast your quota depletes with a realistic experiment running. This is how you find out whether the tier you were quoted is the tier you need.

FAQ

How much does VWO cost per month?

Growth is reported at $314/month and Pro at $972/month, both billed annually. Enterprise is custom-quoted, with third-party trackers reporting entry around $1,265/month billed annually. A free Starter tier also exists. Because Growth, Pro, and Enterprise all route through a demo, treat published figures as starting points.

Does VWO have a free plan?

Yes, a free Starter tier for basic A/B testing, with limits on variations, metrics, and data retention. It is a genuine free tier rather than a time-limited trial, but the caps suit validation rather than an ongoing program. VWO also offers a 30-day trial of paid features.

What is an MTU and why does it matter?

A Monthly Tracked User is a unique visitor who enters one of your experiments in a calendar month. VWO prices on MTUs, so cost scales with how much traffic you test rather than how many tests you run. The risk is a traffic spike pushing you into a higher tier mid-contract. Overage rates are not published, so plan for 120–130% of expected volume.

What does the median company actually pay for VWO?

CostBench reports a median contract of $16,660/year across 93 verified purchases, well above the $314/month Growth list price. That gap reflects how many buyers end up on Pro or Enterprise once MTU volume and modules are counted.

Is VWO or Optimizely cheaper?

VWO, substantially, at the entry level. VWO publishes a $314/month Growth price and has a free tier; Optimizely publishes nothing and reportedly starts around $36,000/year. At enterprise scale with multiple modules they converge, but for client-side A/B testing alone VWO is the cheaper incumbent.

Why is VWO's script a concern for site speed?

VWO loads its testing script from its own servers, and heavier client-side tags can delay rendering and hurt Core Web Vitals, particularly with synchronous anti-flicker snippets. If speed is a hard requirement, compare script weight directly. Stellar ships a 5.4KB async snippet for this reason.

Sources and methodology

VWO publishes some list prices but routes every paid tier through a demo, so the figures here combine VWO's own published numbers with third-party purchase data. Dollar amounts other than the published Growth and Pro prices are reported estimates, not official quotes.

Sources consulted (August 2026):

1. VWO Pricing, official plan structure; the authoritative source for your quote
2. CostBench, VWO Pricing 2026, verified purchase data and median contract value
3. Vendr, VWO Marketplace, MTU model and module-based tier structure
4. Plerdy, Optimizely vs VWO, cautions against outdated "$199/month" figures still circulating

For procurement, treat VWO's written quote as the source of truth and get the MTU allowance and overage rate in the contract.
