What is a good NPS score?

NPS ranges from -100 to +100. Generally: below 0 is critical, 0 to 30 needs improvement, 30 to 50 is good, 50 to 70 is excellent, and above 70 is world-class. However, benchmarks vary significantly by industry. 2026 averages: SaaS 30-50, Ecommerce 40-60, Financial Services 20-40, Healthcare 25-45, Telecom 10-30.

How is NPS calculated?

Survey customers with a single question: "How likely are you to recommend us to a friend or colleague?" on a 0-10 scale. Scores of 9-10 are promoters, 7-8 are passives, and 0-6 are detractors. NPS = % Promoters minus % Detractors. Passives are not counted in the calculation but represent an opportunity.

How does NPS correlate with churn?

Research consistently shows that detractors churn at 6x to 8x the rate of promoters. Industry data suggests promoters have approximately 5% annual churn, passives 15%, and detractors 40%. Converting detractors to passives has a larger revenue impact than converting passives to promoters.

How often should I measure NPS?

Most companies measure NPS quarterly for relationship NPS (overall satisfaction) and after key touchpoints for transactional NPS (specific experience). Continuous measurement with rolling averages is becoming standard for companies with large customer bases.

What This Calculator Does

This Net Promoter Score (NPS) impact calculator models the financial impact of your NPS score on customer retention, referral revenue, and customer lifetime value. It takes your NPS survey results (promoter, passive, and detractor percentages), applies research-based churn and referral rate models, and projects the annual revenue impact across your customer base. The tool includes 2026 industry NPS benchmarks for comparison.

The Formula

NPS = % Promoters - % Detractors | Weighted Churn = (Promoter% x 5%) + (Passive% x 15%) + (Detractor% x 40%) | Referral Revenue = Customers x Referral Rate x Referral Value

NPS is calculated by subtracting the percentage of detractors (score 0-6) from the percentage of promoters (score 9-10). The financial model correlates NPS segments with retention behavior: promoters churn at approximately 5% annually, passives at 15%, and detractors at 40% (based on 2026 customer success research). Referral revenue is modeled from the weighted average referrals per customer (promoters generate 2.5 referrals/year, passives 0.5, detractors near zero) multiplied by a 15% referral conversion rate and the average first-year value of a referred customer.

Common Mistakes to Avoid

Treating NPS as an absolute metric without context. An NPS of 30 is excellent in telecommunications but below average in ecommerce. Always compare against your industry benchmark.
Not surveying a representative sample. NPS results are only valid if the survey reaches a broad, unbiased sample of your customer base. Response rates below 20% may be skewed toward extremes.
Assuming a direct causal relationship between NPS and revenue. NPS is a correlation indicator, not a guarantee. Many factors affect churn and referrals beyond satisfaction scores.
Measuring NPS without acting on the feedback. The value of NPS comes from closing the loop with detractors and understanding what drives promoter loyalty, not just tracking the number.
