NPS Trend
Definition
Period-over-period change in NPS score — the trajectory signal that matters more than any single absolute score. A 5-point swing between adjacent quarters is usually more informative than a "good" or "bad" absolute label, because the methodology's noise floor is high enough that absolute comparisons across companies (or even across quarters with different sample sizes) are unreliable. The board reads this to spot deterioration early — a persistent multi-quarter decline is one of the leading indicators of pending churn. Common pitfall: comparing periods with very different sample sizes or response rates — a "decline" from 45 to 35 means very different things at n=30 vs. n=300.
Why it matters
NPS's methodology noise makes absolute scores hard to interpret across companies. The trend within a single company's own measurement cadence is more reliable — a sustained decline is a leading indicator of churn risk even when the absolute score still reads "good".
How it's calculated
nps_trend = NPS_current_period − NPS_prior_period (delta in points, not %). Sample size and response rate should be reported alongside both periods. How to interpret it
There is no citation-grade benchmark for trend magnitude; treat any single-quarter swing of ±5 points or more as worth narrative explanation, and any 2+ consecutive declines as a yellow flag for the board. Always cite sample size deltas — if response rate or n changed materially, the trend may be measurement artifact rather than real movement.

Net Promoter Score — % of survey respondents who are promoters (score 9–10) minus % detractors (0–6), passives (7–8) excluded. Per the original NPS methodology (Reichheld, Bain & Company, 2003). The score ranges from −100 to +100. The board reads NPS as one read on product-market fit and word-of-mouth potential, not as a precise customer-loyalty measurement — the methodology is well-known for being sensitive to sample bias, response rate, and survey timing. Common pitfall: comparing NPS across companies without normalizing for industry — B2B SaaS NPS distributions sit much higher than consumer-app NPS, and the absolute number means little without a peer cohort.
Free-form commentary from the CS / Sales leadership on retention trends, cohort behavior, and underlying drivers of loyalty (or its absence). Pairs with the quantitative retention KPIs (NRR, GRR, logo retention) and gives the board the "why" behind the numbers — which cohorts are strong, which are weak, what feature engagement correlates with retention, what onboarding changes are landing. Common pitfall: filler prose that restates the numbers without adding causal insight — a board reader should learn something here they could not infer from the metrics page alone.
Named at-risk accounts, root-cause analysis of why they're at risk, and the mitigation plan in flight. Pairs with the quantitative `arr_at_risk` and `percent_arr_at_risk` and gives the board the names + the playbook. Common pitfall: listing the at-risk accounts without the diagnosis or the plan — the board reader needs to see what the team is doing about it, not just what the team is worried about. Also: avoid using this surface as a generic "things are bad" venting forum — keep it account-specific and action-specific.
Active programs the CS / Product / Sales team is running to improve customer health, NPS, retention, or expansion — onboarding revamps, health-score model updates, success-plan rollouts, expansion playbooks, advocacy programs, executive-business-review cadence changes. The board reads this as the "what are we doing about it" companion to the metric pages and the at-risk narrative. Common pitfall: listing initiatives without owner, target metric movement, or checkpoint date — the board cannot follow up on vague programs.
