Product analytics pricing is hard to compare because the five tools most teams shortlist do not even bill the same thing. PostHog, Mixpanel and Amplitude charge by events. Heap charges by sessions. Pendo charges by monthly active users. Only the first three publish paid prices you can budget against without a sales call.
On November 4, 2026 we read each vendor’s pricing page, plan tables and help docs, ran the same event volumes through PostHog’s calculator, Mixpanel’s price table and Amplitude’s Plus estimator, and pulled buyer-reported contract values from Vendr for the quote-only plans. Every number below links to its source. If you are still choosing a tool rather than budgeting for one, start with our guide to product analytics tools.
TLDR
Short answer: Product analytics is free up to 1M to 2M events a month on PostHog, Mixpanel and Amplitude, 10,000 sessions on Heap and 500 monthly active users on Pendo. Past the free tier, 10M events a month costs $324 to $1,080 on PostHog (anonymous to identified events), $840 to $1,176 on Mixpanel Growth and $576 to $720 on Amplitude Plus, depending on billing. Heap and Pendo paid plans are quote-only, and Vendr buyers report median contracts of about $41,000 and $48,500 a year.
- Largest free tier by events: Amplitude, 2M events a month.
- Cheapest published price at 10M events: PostHog for anonymous events ($324 a month), Amplitude Plus for identified users ($576 a month billed annually).
- Annual billing: saves about 29% on Mixpanel and 20% on Amplitude Plus. PostHog has no annual plan or minimum.
- Quote-only: Heap Growth, Pro and Premier; all paid Pendo plans; Amplitude Growth and Enterprise; Mixpanel Enterprise; PostHog Enterprise.
- Median contracts on Vendr: Amplitude $64,000, PostHog $58,173, Pendo $48,500, Heap $41,220, Mixpanel $40,307 a year.

How product analytics tools charge: events, sessions and MAUs
The billing unit decides which tool is cheap for your product, so check it before you compare headline prices.
| Billing unit | Who uses it | What counts | Cheap when | Expensive when |
|---|---|---|---|---|
| Events | PostHog, Mixpanel, Amplitude | Each tracked action, such as a page view, click or signup | Users do a few high-value actions | Autocapture or chatty apps fire many events per user |
| Sessions | Heap | A visit; on web it ends after 30 minutes without a page view, on mobile after 5 minutes of inactivity | Users do a lot in each visit | Users come back many times a day |
| Monthly active users | Pendo | Unique visitors active in your app in the last 30 days | Each user is very active | You have many light or occasional users |
Sources: Heap pricing FAQ, Pendo MAU help article, Mixpanel pricing docs, read November 4, 2026.
A quick way to translate: multiply your monthly active users by the events each one sends. A product with 50,000 monthly active users sending 100 events each produces 5M events a month. On published list prices that is $153 on PostHog if the events are anonymous or $560 if they are identified, $613 on Mixpanel Growth with monthly billing ($438 yearly) and $281 on Amplitude Plus ($225 annual). The same product sits at 50,000 MAU for Pendo, which means a sales quote.
What 2M to 20M events a month costs
These are list prices for analytics events only, before session replay, feature flags or add-ons, entered into each vendor’s own calculator or read from its price table.
| Events a month | PostHog anonymous | PostHog identified | Mixpanel Growth, monthly / yearly | Amplitude Plus, monthly / annual |
|---|---|---|---|---|
| 1M | Free | Free | Free | Free |
| 2M | $50 | $248 | $259 / $185 | $0 / $0 |
| 5M | $153 | $560 | $613 / $438 | $281 / $225 |
| 10M | $324 | $1,080 | $1,176 / $840 | $720 / $576 |
| 20M | $643 | $1,927 | $2,289 / $1,635 | $1,575 / $1,260 |
Sources: PostHog pricing calculator, Mixpanel pricing, Amplitude Plus estimator, read November 4, 2026. US dollars per month.
Three patterns stand out. Amplitude Plus is the cheapest published price for identified users from 5M events up, as long as you stay under its 70M event cap. PostHog is the cheapest for anonymous traffic such as marketing pages from 5M events up (at 2M, Amplitude is still free). Mixpanel with monthly billing has the highest list price at these volumes, but it publishes every tier, so it is the easiest to budget without a call.
Pricing by vendor
PostHog pricing
| Free every month | 1M analytics events, 5K session recordings, 1M feature flag requests, 100K exceptions, 1,500 survey responses |
| Event rates | $0.00005 per anonymous event after 1M, falling to $0.000009 above 250M; identified events $0.000198 each after the first 1M |
| Add-ons | Group analytics $0.000071 per identified event; session replay $0.005 per recording after 5K |
| Platform packages | Boost $250 a month (SSO enforcement, HIPAA BAA), Scale $750 a month (SAML, priority support), Enterprise custom |
| Data history | 1 year free, 7 years on paid usage |
PostHog bills each product separately with no minimum or annual commitment, and you can set a billing limit per product so a traffic spike never overcharges you (PostHog pricing). Its product analytics page lists the full anonymous event ladder: $0.00005 from 1M to 2M events, $0.0000343 to 15M, $0.0000295 to 50M, $0.0000218 to 100M, $0.000015 to 250M and $0.000009 beyond (PostHog product analytics pricing). The catch is identification. Identified events, tied to a known person profile, cost roughly 3 to 5 times as much at our test volumes, so a logged-in SaaS app should budget on the identified column. Security and compliance sit in paid packages: SSO enforcement and a HIPAA BAA start with Boost at $250 a month, SAML with Scale at $750 a month (PostHog platform packages).
Mixpanel pricing
| Free | 1M events a month, 10K session replays, 1k experiment users, 10 active flags, 5 saved reports per user |
| Growth | From $0 with the first 1M events free; published tiers from 1.5M ($140 monthly, $100 yearly) to 20M events ($2,289 monthly, $1,635 yearly) |
| Enterprise | Custom; up to 1 trillion events, custom replay and data retention |
| Add-ons | Group Analytics and Data Pipelines on paid plans, for an extra fee |
Mixpanel is the most transparent vendor here: every Growth tier is listed with monthly and yearly prices, and yearly billing cuts about 29% at each tier (Mixpanel pricing). Growth includes 20K session replays (up to 500K) and up to 50 active feature flags. Identity events such as $identify and $merge do not count toward your bill, and Growth plans bought after February 2025 include the first 1M events free (Mixpanel pricing docs). Above 20M events a month you move to Enterprise, which is quote-only. Vendr reports a median Mixpanel contract of $40,307 a year across 226 purchases (Vendr).
Amplitude pricing
| Free | 2M events a month, 10K session replays, limited experiments, guides and surveys |
| Plus | From $0 with the first 2M events free, card required; scales to 70M events (700K MTU); 2-year data retention |
| Growth and Enterprise | Event-based, custom quotes; SSO from Growth; 20K and 50K monthly session replays |
| Vendr median | $64,000 a year, range $24,750 to $379,933 across 422 purchases |
Amplitude publishes prices only for Plus, through the Estimate bill link on its pricing page, and annual billing comes out about 20% lower than monthly in that estimator (Amplitude pricing). Every plan includes analytics, session replay, experimentation and guides at limited volumes, and seats are unlimited. Growth and Enterprise are custom quotes, and that is where most of the spend sits: Vendr’s median Amplitude contract is the highest of the five tools (Vendr). At least one widely read guide we checked still describes Amplitude as priced by monthly tracked users with a $49 Plus plan. On November 4, 2026 the pricing page bills Free and Plus by events.
Heap pricing
| Free | Up to 10K monthly sessions, core charts, 6 months of data history, SSO |
| Growth | Estimate shown after you sign up and install the snippet; 12 months of history, unlimited users and reports, CSV exports |
| Pro and Premier | Custom session pricing; account analytics on Pro, warehouse integration and unlimited projects on Premier |
| Paid add-ons | Session replay, heatmaps and error analysis (Pro and Premier), Heap Connect warehouse sync (Pro), up to 3 years of data history |
Heap, now part of Contentsquare, bills on sessions and publishes no paid prices (Heap pricing). Two details matter for budgeting. Session replay is not included on any plan; it is an add-on for Pro and Premier only. And if you exceed your plan’s monthly limit, Heap keeps collecting data but asks you to upgrade before you can view it again, so a traffic spike can lock your reports until the contract changes. Vendr reports a median Heap contract of $41,220 a year, with a range of $13,000 to $154,798 across 191 purchases (Vendr).
Pendo pricing
| Pendo Free | Up to 500 MAU; product analytics, in-app guides, Pendo-branded roadmaps and NPS surveys |
| Base | Product analytics and in-app guides; custom MAU volume, on request |
| Core | Adds session replay; on request |
| Ultimate | Adds sentiment surveys (NPS, PMF, CSAT), Orchestrate, Listen and Data Sync; on request |
Pendo prices on monthly active users plus the plan you pick, and says the cost per MAU goes down as your MAU count rises (Pendo pricing). Pendo Free stops working as a free plan once you pass 500 MAU: you cannot create new guides, NPS surveys or segments, and reports switch to trends from a daily random sample of 500 visitors until you upgrade (Pendo Free help article). On paid plans, going over the MAU limit does not interrupt service; your account rep contacts you about a contract change. Pendo pairs product analytics with in-app guides on every plan, including Free, which is why it often competes with digital adoption platforms as much as with pure analytics tools. Vendr’s median Pendo contract is $48,500 a year across 589 purchases (Vendr).
What buyers pay for quote-only plans
When a plan has no list price, contract benchmarks are the closest public evidence. Vendr publishes anonymized purchase data for all five vendors.
| Tool | Median a year | Reported range | Purchases in sample |
|---|---|---|---|
| Amplitude | $64,000 | $24,750 to $379,933 | 422 |
| PostHog | $58,173 | $20,000 to $70,000 | Not shown |
| Pendo | $48,500 | $18,600 to $151,741 | 589 |
| Heap | $41,220 | $13,000 to $154,798 | 191 |
| Mixpanel | $40,307 | $13,250 to $120,102 | 226 |
Read these as benchmarks for negotiated deals, not as list prices. They reflect purchases Vendr has tracked, so they say little about what a small team on a self-serve plan pays. Note too that Vendr’s pages describe Mixpanel and Heap as priced on monthly tracked users, while both vendors’ own pricing pages bill on events and sessions respectively.
Free plans compared
| PostHog | Mixpanel | Amplitude | Heap | Pendo | |
|---|---|---|---|---|---|
| Free allowance | 1M events | 1M events | 2M events | 10K sessions | 500 MAU |
| Session replay | 5K recordings | 10K replays | 10K replays | Not on free | Not on free |
| Data history | 1 year | 2 years | 1 year | 6 months | Not stated |
| What happens at the limit | Usage stops; no surprise charges | Data kept, querying paused until you upgrade to Growth | Not stated on the pricing page | Data kept, reports locked until upgrade | Sampled reports; no new guides, NPS or segments |

Costs that change the bill
- Identified vs anonymous events. On PostHog, 10M identified events cost $1,080 a month against $324 anonymous (PostHog).
- Session replay. PostHog charges $0.005 per recording after 5K. Mixpanel and Amplitude include set quotas by plan. Heap sells replay only as a Pro or Premier add-on, and Pendo includes it from Core.
- Account-level analytics. PostHog group analytics adds $0.000071 per identified event; Mixpanel Group Analytics is a paid add-on on Growth and Enterprise (Mixpanel docs); Heap includes account analytics from Pro.
- Security and compliance. SSO and a HIPAA BAA cost $250 a month on PostHog Boost; on Mixpanel, HIPAA tools are Enterprise only; on Amplitude, SSO starts at Growth.
- Data history. Heap free keeps 6 months and Growth 12; longer history is an add-on. Amplitude Plus keeps 2 years; PostHog paid usage keeps 7.
- Overages. Mixpanel Growth bills events above your plan at an a la carte rate on the next invoice ($0.00028 per event on the 1M plan) and does not offer a billing limit (Mixpanel docs). Heap locks reports until you upgrade, Pendo Free restricts guide creation, and PostHog stops usage at your billing limit. Ask every vendor what happens in a spike month before you sign.
Startup programs

Which pricing model fits your team
- Early-stage, under 2M events a month: stay free on Amplitude (2M events) or on PostHog or Mixpanel (1M events), and apply for a startup program if you qualify.
- Lots of logged-out traffic: PostHog’s anonymous event rate is the lowest published price from 5M events a month up.
- Logged-in SaaS at 5M to 20M events: Amplitude Plus has the lowest list price, especially billed annually; Mixpanel costs more but has the clearest tier table.
- You want no tracking plan and capture everything: Heap’s session pricing can suit products where users do a lot per visit, but get a written estimate and ask about the overage lock.
- Analytics plus in-app guides for a B2B app: Pendo bundles both on every plan; budget for a quote above 500 MAU.

How we priced these tools
On November 4, 2026 we read the pricing pages, plan tables and FAQs of PostHog, Mixpanel, Amplitude, Heap and Pendo, plus Mixpanel’s pricing docs and Pendo’s help articles on Pendo Free and MAU counting. We entered 2M, 5M, 10M and 20M events into PostHog’s calculator (anonymous and identified separately) and Amplitude’s Plus estimator (monthly and annual), and read Mixpanel’s published Growth table. We captured each pricing page the same day. Contract medians and ranges come from Vendr’s public marketplace pages. We did not request sales quotes, so prices exclude discounts, taxes and negotiated terms, and computed figures (such as the 29% and 20% annual savings) are derived from published price pairs.
