PostHog true cost: the 36-month total
PostHog costs $2,700 over 36 months on PAYG Session Replay (20K) at 1 account, billed annually, before 4 cost lines that sit outside the plan price.
What PostHog costs over 36 months
Every figure below is PostHog's own published rate, annualised and multiplied out over 36 months at 1 account. Where PostHog publishes no rate, the row says so instead of guessing.
1 tier is sales-led (Enterprise), so it carries no figure here.
Renewal sensitivity: three scenarios, not a forecast
Nobody knows what PostHog charges in 2029. The table below is arithmetic on a rate you choose, not a prediction: it compounds the year-one total forward at 0%, 5% and 10% so you can see how much of the 36-month figure is exposed to a renewal you have not negotiated yet.
Scenario arithmetic on PostHog's own published year-one figure. Uplift rates are illustrative inputs, not observed or predicted rates.
What sits outside the PostHog list price
4 lines, sorted by when in the contract lifecycle they land. Lines marked as derived are arithmetic on PostHog's own tier table rather than vendor prose.
Each line, what triggers it, and how to avoid it
Trial and free-tier conversion
Stated on the pricing page: Product Analytics: $0.00005/event after free tier
What triggers it. Fires when free stops being free. Worth mapping precisely, because free-tier limits are where product analytics platform tools do most of their upgrade engineering.
How to avoid it. Ask for the trial to be extended to cover a full billing cycle of real use. Vendors grant this far more often than buyers ask.
Trial and free-tier conversion
Stated on the pricing page: Session Replay: $0.005/recording after free tier
What triggers it. Triggered by the trial expiring or a free-tier limit being crossed. The $2,700 figure above starts counting from that moment, not from signature.
How to avoid it. Diarise the conversion date and the cancellation route on day one. An unmanaged trial converting to PAYG Session Replay (20K) is the cheapest mistake on this page to prevent and the most common one to make.
Trial and free-tier conversion
Stated on the pricing page: Surveys: $0.10/response after free tier
What triggers it. The clock, not a decision, triggers this one. PostHog's free entry point ends on a date, and the $75 a month for 1 account rate starts whether or not anyone has finished evaluating.
How to avoid it. Diarise the conversion date and the cancellation route on day one. An unmanaged trial converting to PAYG Session Replay (20K) is the cheapest mistake on this page to prevent and the most common one to make.
Unpublished pricing
Derived from the published tiers: 1 of 4 PostHog tiers publish no price (Enterprise). No total on this page includes them.
What triggers it. Triggered by nothing you do. This is simply a number PostHog does not publish. Every unpublished component is a hole in the $2,700 figure, which is built only from rates the vendor states.
How to avoid it. Ask for it in writing, itemised, before shortlisting. A vendor that will not put a number on a component at evaluation stage rarely gets more forthcoming after signature.
How that compares across product analytics and behavioral analytics
The median product analytics and behavioral analytics tool we track charges $21 a month at its cheapest paid tier. Re-expressed on the same basis as the figure above, 1 account for 36 months, that median works out at $756.
PostHog lands $1,944 above that figure, 257.1%, measured across 11 tracked tools. A gap either way is a question, not a verdict: cheaper often means fewer included seats or a thinner support tier, and the fee lines below are where that difference usually reappears.
What changes at enterprise scale
Everything above prices the self-serve ladder. Enterprise sits off that ladder, which means the $2,700 figure is a floor for a large deployment rather than an estimate of one.
Enterprise adds SSO, audit logs, dedicated support and custom commits but is not publicly priced.
Frequently asked questions
How much does PostHog cost over three years?
$2,700 on PAYG Session Replay (20K) at 1 account, billed annually, which is $75 a month held flat for 36 months. That figure covers the subscription only.
Does paying PostHog annually save money?
PostHog publishes the same effective rate either way on PAYG Session Replay (20K), so there is no prepay discount to capture. Keep the monthly option unless the vendor offers something for the commitment.
What does PostHog charge for outside the plan price?
4 lines: trial and free-tier conversion, trial and free-tier conversion, trial and free-tier conversion, unpublished pricing. Each one is broken down above with what triggers it and how to avoid it.
Could PostHog cost more at renewal?
Possibly, and nothing on this page predicts it. If the rate held flat the three-year total would be $2,700; at a hypothetical 10% a year it would be $2,979. Cap the uplift in the contract and the question stops mattering.
Is PostHog expensive for product analytics and behavioral analytics?
