Cohort Retention & RFM Funnel Analyzer

· Last updated：2026-08-28

Paste an order or event CSV and get the growth stack in one page: a cohort retention triangle with a heatmap, RFM quintile scoring mapped to the ten standard lifecycle segments, and a strict-order funnel.

Details

What this tool helps you do

A semantic layer over your transaction log, not another generic chart. Cohorts are formed by each customer's first-order month (or ISO week), and retention is the share of the cohort that orders again in each later period — rendered as the classic triangle heatmap with per-cell user counts, size-weighted average retention per period index, and best/worst cohort callouts. RFM follows the standard method: rank every customer on Recency (days since last order), Frequency (order count) and Monetary (total spend), cut each dimension into quintile scores 1–5, and map the three-digit code to the ten lifecycle segments — Champions, Loyal Customers, Potential Loyalists, New Customers, Promising, Needs Attention, At Risk, Can't Lose Them, Hibernating, Lost — each with share of base, average spend, and a recommended play. The funnel counts users who reached each step in strict chronological order (a user only counts for a step if they completed the previous step earlier in time). Everything runs on a header-flexible CSV (user/customer, date/timestamp, amount/revenue, event/action), so an ecommerce export, a Stripe CSV or a product-event dump all work without reformatting.

Overview

The Cohort Retention & RFM Funnel Analyzer transforms raw transaction logs and event CSVs into an actionable growth intelligence dashboard. It automatically computes monthly or weekly retention triangle heatmaps, classifies customers across ten standard RFM quintile segments, and measures strict-order step conversions.

When to use

  • Evaluating repeat purchase rates and long-term customer churn over weekly or monthly cohorts.
  • Segmenting an ecommerce customer base into RFM tiers (Champions, At Risk, Lost) to tailor lifecycle marketing campaigns.
  • Tracking strict-order conversion drop-offs from product event logs or checkout flow exports.

How it works

  1. 1Paste an order or event CSV containing flexible column headers such as user/customer, date/timestamp, amount/revenue, and event/action.
  2. 2Select the cohort aggregation granularity (month or ISO week), configure the number of periods to display, and optionally define an analysis cutoff date.
  3. 3Provide comma-separated funnel step names if analyzing sequential conversion milestones from an event column.
  4. 4Generate the report to inspect retention triangles with cell counts, size-weighted retention averages, RFM lifecycle segment distributions, and strict-order funnel drop-offs.

Use cases

  • E-commerce stores analyzing repeat-order curves across acquisition months to measure seasonal cohort retention.
  • CRM marketers identifying high-value customers needing re-engagement, such as At Risk and Can't Lose Them segments.
  • Product teams measuring strict chronological drop-off across onboarding or multi-step checkout funnels.

Who it's for

Best for

  • Convert content in the browser.
  • Workflows where 队列周期 matters, such as 月 or 周（ISO）.
  • The “Four monthly cohorts with RFM segmentation” workflow, done in one pass.

Not ideal for

  • Fully automated batch jobs — this page is built for interactive use; use the API endpoint for scripts.
  • Content in other formats — this tool expects content.

Edge cases & common failures

  • Very large files

    Large files take longer and can hit browser memory limits — try a smaller sample first.

  • Skipping the output check

    Compare the first rows or pages of the output with the input before using it in production.

  • Files from unusual exporters

    Some files use format variants that do not convert cleanly — if the output looks wrong, re-save the file from the app that created it and try again.

Examples

1. Monthly Repeat Purchase & RFM Breakdown

Ecommerce Growth Manager

Background

An online store exports transaction records from Shopify to evaluate customer retention and high-value customer health across Q1.

Problem

Manual pivot tables fail to cleanly show cohort decay over time or automate 3-dimension RFM segment assignments.

How to use

Paste the raw order log into the CSV textarea, choose monthly cohorts, set the period count to 3, and run the analysis.

cohortPeriod: month, periodsCount: 3, analysisDate: 2026-04-06

Outcome

Displays a retention heatmap showing 55.6% average Month-1 retention and segments customers into Champions and Can't Lose Them buckets with actionable plays.

2. Strict-Order Signup-to-Purchase Funnel

Product Analyst

Background

A product team needs to evaluate drop-offs in their conversion funnel from raw tracking events.

Problem

Aggregate event counts overstate conversion because users who bypass mandatory setup steps are incorrectly tallied.

How to use

Paste the event log containing user_id, date, amount, and event columns, then enter the funnel steps in chronological sequence.

FAQ

What CSV column headers are recognized?

The analyzer recognizes standard variations for user IDs (user_id, customer, user), timestamps (date, timestamp), amounts (amount, revenue, spend), and event names (event, action).

How are customer cohorts defined?

Cohorts are grouped by the timestamp of each customer's first recorded order or transaction, grouped by month or ISO week.

How does the strict-order funnel calculate conversion?

A user is only counted for a given step if they completed all preceding steps chronologically earlier in the dataset.

What segments are generated by the RFM model?

Customers are ranked by Recency, Frequency, and Monetary quintiles (1–5) and mapped into 10 standard lifecycle segments, including Champions, Loyal Customers, At Risk, and Lost.

What happens if I leave the analysis date blank?

When omitted, the tool automatically defaults to the latest date found in the provided CSV dataset.
