PostHog Pricing 2026: Complete Breakdown of Plans, Costs, and How Billing Works
PostHog’s pricing can feel unnecessarily complicated. Unlike analytics platforms that charge one way, PostHog operates on a multi-product, usage-based model where you pay separately for Product Analytics, Session Replay, Feature Flags, A/B Testing, and Surveys. Events, recordings, flag requests, and survey responses all count differently toward your bill. This guide cuts through the confusion and shows you exactly what PostHog will cost for your use case.
PostHog Pricing Model Overview: Usage-Based, Per-Product
PostHog ditched flat-rate pricing entirely. Everything runs on usage metrics tied to the specific product:
- Product Analytics: Charged per event (every action tracked)
- Session Replay: Charged per recording (every user session captured)
- Feature Flags: Charged per flag decision/request
- A/B Testing: Charged per experiment variant exposure
- Surveys: Charged per survey response
You only pay for what you use. If you enable Feature Flags but don’t use Session Replay, you won’t be charged for recordings. The catch: costs scale immediately with growth, and volume discounts are built into the pricing tiers, not automatically applied.
PostHog Free Tier: What’s Actually Free
PostHog’s free plan removes the biggest barrier to entry—you genuinely get a functional analytics platform without a credit card. Here’s what the Free tier includes:
- 1 million events/month for Product Analytics
- Unlimited team members (unlike Mixpanel’s 1-person limit)
- 7-day data retention (events older than 7 days are deleted)
- Basic session replay: 50 recordings/month (stored for 1 day)
- Unlimited feature flags (but charged separately if you go paid)
- Basic dashboards and reporting
- Basic API access
- No session replay retention beyond 1 day
The Free tier is genuinely useful for small teams validating products, but the 7-day event retention is a killer limitation. You can’t build historical trend analysis. Session replay is essentially a demo—50 recordings/month isn’t enough for real debugging.
Who the Free tier works for: Pre-launch startups, open-source projects, hobby apps, and teams piloting PostHog alongside existing tools.
PostHog Paid Tiers: Startup, Growth, and Scale Plans
PostHog introduced named tiers in 2025 to replace pure consumption-based pricing, though usage-based billing remains the foundation. The main difference between tiers is pricing per unit and included limits.
Startup Plan: $0–$500/month (roughly)
Starter-stage usage typically lands here. Pricing for the Startup tier includes:
- Product Analytics: $0.00050 per event (50¢ per million events)
- Session Replay: $0.0050 per recording (50¢ per 100 recordings)
- Feature Flags: $0.0000025 per flag decision ($2.50 per million requests)
- A/B Testing: $0.00001 per variant exposure (included with Feature Flags pricing)
- Surveys: $0.01 per response (1¢ per response)
- 90-day data retention for events
- Up to 3 team members (additional members $50/month each)
- Community support via Slack/Discord
Example monthly cost for Startup tier: An app with 5 million events, 200 session recordings, and 50,000 feature flag requests would cost approximately $2,500 + $100 + $0.13 = $2,600.13/month before volume discounts.
Who this tier is for: Early-stage SaaS companies with 1–10 million monthly events, growing side projects that need production-grade analytics.
Growth Plan: $500–$2,500/month (typical range)
Growth tier pricing improves unit economics as volume increases:
- Product Analytics: $0.00035 per event (35¢ per million)
- Session Replay: $0.0040 per recording (40¢ per 100)
- Feature Flags: $0.000001 per flag decision ($1.00 per million)
- Surveys: $0.005 per response
- 1-year data retention for events
- Up to 10 team members
- Slack support channel with faster response
- Priority in feature request backlog
Cost example: 50 million monthly events, 2,000 session recordings, 500,000 flag requests = $17,500 + $800 + $0.50 = $18,300/month. That’s roughly a 30% discount per event versus Startup tier pricing.
Who this tier is for: B2B SaaS companies with product-market fit, apps with 10–100 million monthly events, teams that need multiple team members and deeper support.
Scale Plan: $2,500+/month
Scale tier is for organizations running substantial analytics operations:
- Product Analytics: $0.00025 per event (25¢ per million)
- Session Replay: $0.0030 per recording (30¢ per 100)
- Feature Flags: $0.0000005 per decision ($0.50 per million)
- Unlimited team members
- 2-year event data retention
- Dedicated Slack channel with PostHog team
- Quarterly strategy calls
- Custom data retention available
Cost example: 500 million monthly events, 20,000 session recordings, 5 million flag requests = $125,000 + $6,000 + $2.50 = $131,002.50/month. Per-event pricing is now 50% cheaper than Startup tier.
Who this tier is for: Mid-market SaaS platforms, apps with 100+ million monthly active events, enterprises piloting with favorable pricing before negotiating contracts.
Enterprise Plan: Custom Pricing
PostHog doesn’t publicly list Enterprise pricing because it’s negotiated. Enterprise plans typically include:
- Custom per-event pricing (usually $0.00015–$0.0002 per event for massive volumes)
- Unlimited data retention with custom archival options
- Dedicated account manager
- SLA guarantees (99.9% uptime)
- Advanced security: SSO, SOC 2 Type II compliance, on-premise or private cloud deployments
- Custom integrations and API rate limit increases
- Priority infrastructure scaling
Enterprise deals typically kick in at $50,000+/year (~$4,000/month). Companies with 1+ billion monthly events often negotiate to $0.0001–$0.00015 per event, turning a billion-event month into $100,000–$150,000.
When Enterprise becomes necessary: 500+ million monthly events, regulatory compliance requirements (healthcare, finance), need for on-premise deployment, SLA requirements.
How PostHog Billing Actually Works: Combining Products and Volume Discounts
PostHog doesn’t charge each product separately on different line items—it combines usage across products into a single bill. Here’s the critical detail: volume discounts apply to each product category independently, not your overall spend.
Example: If you generate 100 million events (Startup tier pricing = $50,000) but only 50,000 session recordings (Startup tier = $250), you don’t suddenly qualify for Growth tier on both products. The 100 million events qualifies for Growth-tier discounts (~$35,000), but the 50,000 recordings stays at Startup pricing.
This matters because teams often assume a single product’s volume gets them to the next tier across the board. It doesn’t.
Overages: PostHog doesn’t have hard caps. If you exceed your plan’s expected usage, you’re automatically charged at the per-unit rate for that tier. There’s no surprise invoice spike—you’re charged the same rate as your committed tier.
Product-Specific Pricing Deep Dive
Product Analytics Pricing
The most common charge. PostHog counts every event—page views, clicks, custom events, everything. At scale, this dominates your bill.
Typical event volumes:
- Mobile app with 10,000 daily active users: ~3–5 million events/month (10–15 events per session)
- SaaS platform with 1,000 daily active users: ~1–3 million events/month (higher per-user intensity)
- High-traffic website with 1 million monthly visitors: 5–20 million events/month (depends on tracking density)
- Enterprise web app with 100,000 daily users: 100+ million events/month
PostHog also offers event sampling to reduce costs: automatically capture 1 in N events, reducing your billable volume. A 50% sample rate cuts your analytics bill in half but trades granularity for cost.
Session Replay Pricing
Session Replay charges per recording, not per minute watched. A 2-minute recording and a 30-minute recording cost the same. At Startup tier ($0.0050 per recording), 10,000 monthly recordings = $50.
PostHog’s session replay includes:
- Full DOM capture (all HTML/CSS changes recorded)
- Network activity logging (API calls, response times)
- Console logs and browser errors
- Privacy masking (credit card numbers, passwords automatically redacted)
The gotcha: PostHog captures recordings by default on all users. If you have 100,000 monthly users, that’s potentially 100,000 recordings at $0.005 each = $500/month on the free tier. Many teams enable session replay without realizing the cost implications.
Solution: Enable session replay on a sample rate (10% of users = 10,000 recordings at $50/month) or only for users matching specific criteria.
Feature Flags Pricing
Feature Flags charge per “flag decision”—every time your app checks whether a flag is enabled. At Startup tier ($0.0000025 per decision), 1 million daily flag checks = $75/month. This is cheap and often negligible unless you’re making hundreds of millions of flag requests daily.
A/B Testing Pricing
A/B Testing rides on Feature Flags pricing. Each variant exposure counts as a flag decision. Running 5 A/B tests simultaneously checking flags 10 million times daily = 50 million flag requests = $125/month at Startup tier.
Surveys Pricing
Surveys charge per response ($0.01 at Startup tier). A survey shown to 10,000 users with 20% response rate = 2,000 responses = $20/month. Surveys are typically the cheapest product category.
Cost Examples: Real-World Scenarios
Small Startup: 100,000 Monthly Events
- Product Analytics: 100,000 events × $0.00050 = $50
- Session Replay: 500 recordings × $0.005 = $2.50
- Feature Flags: 1 million requests × $0.0000025 = $2.50
- Monthly total: ~$55
- Verdict: Free tier is more cost-effective unless data retention is critical
Growing SaaS: 5 Million Monthly Events
- Product Analytics: 5,000,000 × $0.00050 = $2,500
- Session Replay: 10,000 recordings × $0.005 = $50
- Feature Flags: 50 million requests × $0.0000025 = $125
- A/B Testing: Included with flags
- Monthly total: ~$2,675 (Startup tier)
- Verdict: Startup tier is the sweet spot; consider event sampling to reduce costs
Enterprise: 500 Million Monthly Events
- Product Analytics: 500,000,000 × $0.00025 (Scale tier) = $125,000
- Session Replay: 50,000 recordings × $0.003 = $150
- Feature Flags: 2 billion requests × $0.0000005 = $1,000
- A/B Testing & Surveys: Included/negligible
- Monthly total: ~$126,150 (Scale tier)
- Verdict: Enterprise negotiation likely saves 15–25%, landing at ~$100,000–$107,000/month
Hidden Costs and Considerations
Team Members Beyond Included Seats
Startup tier includes 3 team members; Growth includes 10; Scale is unlimited. Each additional team member on Startup = $50/month. A team of 8 people on Startup tier = $250/month in overages.
Data Retention Costs
PostHog’s free tier offers 7-day retention; Startup tier is 90 days; Growth is 1 year; Scale is 2 years. Longer retention isn’t a separate line item—it’s tier-bound. You can’t buy 5-year retention on Startup tier; you’d need to move to Enterprise.
Integrations and Webhooks
No additional charge for integrations (Segment, mParticle, Rudderstack), but webhook volume counts toward your event quota if you’re pushing data back to PostH
