Renewal Forecasting
The Renewal Forecasting engine computes a probability of renewal for every upcoming renewal in your portfolio, then aggregates those probabilities into org-level GRR and NRR projections. Each probability is decomposed into explicit risk factors and positive signals so teams can see exactly why a renewal is confident or at risk.Renewal Forecasting builds on data from the Scoring Engine (health scores, risk scores) and the Signals taxonomy (critical signal detection). It does not replace those systems — it consumes their outputs to produce forward-looking retention projections.
How It Works
Probability Model
Each renewal receives a probability score between 0.01 and 0.99 computed from multiple input signals including:- Health Score — Current account health level
- Risk Score — Renewal risk assessment
- Engagement Score — Activity and usage patterns
- Disposition — Current renewal lifecycle state
- Days to Renewal — Proximity to renewal date and urgency
- Active Playbooks — Whether intervention plays are in progress
- Critical Signals — Recent critical signals on the account
- NPS Score — Customer satisfaction level
- Contract Tenure — Length of customer relationship
- Deal Size — ARR-based scrutiny adjustment
Exact model weights, base probability, adjustment formulas, and clamp values are available in the PILLAR Implementation Guide provided to active customers.
Confidence Tiers
Each renewal is classified into a confidence tier based on its computed probability:| Tier | Meaning |
|---|---|
| high | Renewal is highly likely |
| medium | Some risk factors present |
| at_risk | Significant risk — intervention recommended |
Org-Level Projections
The engine aggregates per-renewal probabilities into portfolio-level metrics:| Metric | Description |
|---|---|
| Projected GRR | ARR-weighted average of renewal probabilities |
| Projected NRR | GRR adjusted for expansion rate |
| Weighted Renewal ARR | Probability-weighted sum across all renewals |
| High Confidence ARR | ARR from high-confidence renewals |
| At-Risk ARR | ARR from at-risk renewals |
Data Model
PILLAR stores org-level forecast snapshots for trend tracking and per-renewal probability computations with full risk/signal decomposition. Each forecast is versioned and keyed by organization and period.Detailed data model schemas are available in the PILLAR Implementation Guide provided to active customers.
Period Formats
The forecast engine accepts multiple period formats:| Format | Example | Range |
|---|---|---|
| Quarter | 2026-Q2 | Apr 1 - Jun 30 |
| Half | 2026-H2 | Jul 1 - Dec 31 |
| Year | 2026 | Jan 1 - Dec 31 |
