Mixpanel vs Amplitude vs PostHog: Pricing Breakdown
Mixpanel, Amplitude, or PostHog? We break down real pricing models, hidden costs, and cost-at-scale to help SaaS teams pick the right analytics platform.
Introduction
Choosing the best product analytics platform often comes down to a single, unglamorous factor: what it actually costs at your scale. Mixpanel, Amplitude, and PostHog each use fundamentally different pricing architectures, and the gap between their bills can widen from a rounding error to tens of thousands of dollars per year depending on your event volume, team size, and data infrastructure. Most surface-level comparisons skim past the pricing mechanics that cause post-onboarding sticker shock, like data export fees, feature gating behind enterprise tiers, and self-hosting infrastructure overhead. This analytics platform comparison strips away the marketing pages and focuses on the real cost-of-ownership trade-offs at startup, growth, and enterprise scale.
Key Takeaway: PostHog offers the lowest entry cost and the most transparent per-event pricing, but Mixpanel delivers the most predictable scaling for mid-market SaaS teams, while Amplitude's value concentrates at the enterprise tier where its bundled features offset its premium price.
How Each Pricing Model Actually Works
The core pricing confusion in this event tracking platform comparison stems from the fact that these three platforms do not even measure "usage" the same way. Understanding the unit of measurement each vendor charges against is the first step toward projecting real costs at your specific scale.
Event-Based vs. Transparent Per-Event
Both Mixpanel and Amplitude have converged on event-based pricing in recent years, but the similarity is mostly cosmetic. Here is how each model breaks down in practice:
Mixpanel: Charges per tracked event with a free tier covering 20 million events per month, then scales in volume tiers on its Growth plan starting around $28/month for additional capacity.
Amplitude: Also uses event-based pricing with a free Starter tier, but gates critical features like funnel analysis depth, behavioral cohorts, and advanced queries behind its Growth and Enterprise tiers where pricing is custom and opaque.
PostHog: Charges transparently per event with published unit pricing (roughly $0.00031 per event beyond the 1 million free monthly events), and every feature ships with the same plan rather than being gated by tier.
Self-hosting option: PostHog self-hosted vs cloud deployments eliminate per-event fees entirely but introduce infrastructure costs that most teams underestimate at the outset.
What the Free Tiers Actually Include
Free tiers are where these platforms hook teams, but the boundaries of "free" differ dramatically. Mixpanel's free plan is genuinely generous at 20 million events, making it viable for early-stage SaaS products running lightweight tracking. Amplitude's free Starter plan tracks events but restricts access to deeper product usage analytics features, meaning teams often hit a functional wall before they hit a volume wall. PostHog gives 1 million free events for product analytics, plus separate free tiers for session replays, feature flags, and surveys, but each module prices independently once you exceed those limits. That transparent but complex independent pricing for each feature can surprise teams who assumed a single bill.
Real Cost Scenarios at Three Growth Stages
Abstract pricing models only become meaningful when applied to concrete usage scenarios. The following comparison maps each platform's cost against three recognizable SaaS profiles to reveal where the pricing models diverge most aggressively.
Startup, Growth, and Enterprise Cost Comparison
The table below models approximate monthly costs for three usage profiles: a startup tracking 5 million events per month, a growth-stage product at 50 million events, and an enterprise at 250 million events. All figures assume cloud-hosted deployments and published or commonly reported pricing as of mid-2026.
Usage Tier | Mixpanel | Amplitude | PostHog (Cloud) |
|---|---|---|---|
Startup (5M events/mo) | Free | Free (feature-limited) | ~$12/mo |
Growth (50M events/mo) | ~$450-$800/mo | ~$1,000-$2,000/mo (custom) | ~$310/mo |
Enterprise (250M events/mo) | Custom (~$2,500-$5,000/mo) | Custom (~$4,000-$8,000/mo) | ~$1,550/mo |
PostHog's per-event transparency makes it the cheapest option at every tier on raw event costs alone. Mixpanel occupies the middle ground, with its generous free tier absorbing startup usage entirely. Amplitude becomes the most expensive option at the growth stage because its Growth plan pricing is custom-negotiated, and the features most growth teams need (like advanced cohort analysis tools and behavioral grouping) live behind that paywall. At enterprise scale, Amplitude's cost premium may be justified by bundled capabilities, but teams paying $6,000+ per month should expect the same depth from warehouse-native analytics tools that cost a fraction of that.
Hidden Costs That Change the Math
Sticker price tells half the story. Mixpanel charges for data exports through its pipeline integrations, and its Group Analytics feature (essential for B2B SaaS tracking accounts rather than users) is an add-on that increases the bill by 20-40% depending on volume. Amplitude gates features like Experiment (A/B testing) and CDP into separate products, each with their own pricing. A team that thinks it is buying "Amplitude" is often buying three products.
PostHog's hidden cost is infrastructure. Self-hosting PostHog eliminates per-event fees but introduces cloud infrastructure costs averaging around $500 per month and meaningful engineering overhead for setup, maintenance, Kubernetes management, and upgrades. Teams without a dedicated DevOps resource should budget 10-15 hours per month of engineering time on top of the hosting bill, which often erases the savings PostHog promises on paper. For GDPR compliant analytics tools requirements, the self-hosted option does offer complete EU data residency control, a genuine advantage for EU-based SaaS teams that cannot use US-hosted cloud analytics.
Where Each Platform Wins on Cost-Efficiency
Pricing is not just about who is cheapest. The question is which platform delivers the most analytical value per dollar at each team's specific stage and technical maturity.
Best Fits by Team Profile
Mixpanel wins for non-technical growth and product teams at mid-market SaaS companies tracking between 20 and 100 million events monthly. Its UI is the most intuitive of the three for ad-hoc analysis, and its pricing scales more predictably than Amplitude's custom tiers. Teams that prioritize retention analytics and funnel analysis without heavy engineering support will find the cost-to-capability ratio strongest here.
Amplitude wins at the enterprise tier for organizations that need deeply integrated experimentation and CDP capabilities alongside product analytics. If the alternative is buying Mixpanel plus a separate A/B testing tool plus a separate CDP, Amplitude's consolidated cost may actually be lower. The pricing premium only makes sense when teams use the full stack.
PostHog wins for technically capable SaaS teams that want maximum transparency and are comfortable reading pricing calculators, managing event budgets across modules, or running self-hosted infrastructure. It is the only option that lets teams own their data pipeline end-to-end without vendor lock-in on exports.
The Verdict on Cost-of-Ownership
For teams tracking under 20 million events monthly, Mixpanel's free tier makes the decision simple. For growth-stage products between 20 and 100 million events, PostHog cloud offers the lowest total cost, but only if teams are disciplined about which modules they activate. For enterprise deployments above 100 million events, the decision hinges on whether the team needs Amplitude's bundled experimentation and CDP or whether they can assemble a best-of-breed stack around PostHog at lower overall cost. TrackRaptor has consistently tracked these pricing shifts across the product analytics ecosystem, and the pattern is clear: the cheapest platform is not always the cheapest decision once you factor in engineering time, feature gaps, and migration costs.
Conclusion
The Mixpanel vs Amplitude vs Posthog pricing comparison reveals that no single platform is universally cheapest. PostHog wins on raw per-event cost and transparency, Mixpanel wins on free-tier generosity and mid-market predictability, and Amplitude wins when enterprise teams can leverage its full product suite. Teams should model their specific event volumes, required features, and engineering capacity against each pricing architecture before committing. The most expensive analytics mistake is not picking the wrong price tier; it is picking the wrong pricing model for how your data volume will grow over the next 18 months.
