This converter uses a linear regression formula to estimate Google star ratings from NPS scores:
Rating = (NPS + 100) ÷ 200 × 4 + 1
• NPS of -100 maps to a 1.0 star rating
• NPS of 0 maps to a 3.0 star rating
• NPS of 100 maps to a 5.0 star rating
The reverse conversion uses the inverse formula:
NPS = (Rating - 1) ÷ 4 × 200 - 100
• 1 star maps to NPS of -100
• 3 stars maps to NPS of 0
• 5 stars maps to NPS of 100
Your NPS score falls into one of four categories:
Input your NPS score (between -100 and 100) or Google rating (1-5 stars) to see the conversion instantly.

Strategic planningNPS and Google ratings measure customer satisfaction differently. NPS asks "How likely are you to recommend?" while star ratings reflect overall satisfaction. This converter helps you understand how your NPS translates to estimated review ratings for benchmarking and goal-setting purposes.
This converter provides an estimated correlation based on industry research. The formula uses linear regression to map NPS scores to star ratings. However, the actual relationship varies by industry, customer base, and review platform. Use this as a benchmarking tool rather than an exact prediction.
An NPS above 0 is good (more promoters than detractors). An NPS above 30 is considered excellent. An NPS above 50 is world-class. However, benchmarks vary by industry. Compare your NPS to your industry average rather than a universal standard.
Focus on converting detractors to passives and passives to promoters. Act on the feedback from detractors, improve key pain points, and create moments of delight for your customers. Measure NPS regularly to track progress.
