Volta — NPS Trends

Situation

Are customers promoters or neutrals? And which drivers move NPS.

Task

I needed to see where customers sit between promoter and neutral, and my job was to find which drivers actually move the score.

Actions

  • Monthly NPS across 18 survey months.
  • NPS by driver and promoter mix.

Result

  • NPS hovers near zero: peak +12.9 (2024-10), bottom −1.8 (2024-09).
  • app_quality +30.3 and product +29.4 are the strongest drivers; fees −59.4 is the main source of dissatisfaction.
  • onboarding −23.6 is consistent with the KYC bottleneck from Project 1.

Recommendations

  • Address the perception of fees (transparency, tariffs) — the biggest negative.
  • Clean up onboarding (tie-in with the KYC fix).
  • Lean on app quality as a strength in messaging.

NPS by month

Monthly NPS across 18 survey months (2024-07 … 2025-12). NPS hovers around zero — customers are mostly neutral rather than promoters.

-1.5 3.5 8.5 13.5 NPS 2024-07 — NPS: 0.5 2024-08 — NPS: 9.4 2024-09 — NPS: -1.8 2024-10 — NPS: 12.9 2024-11 — NPS: 10.3 2024-12 — NPS: 9.4 2025-01 — NPS: 6.9 2025-02 — NPS: 7.5 2025-03 — NPS: -0.9 2025-04 — NPS: -1.1 2025-05 — NPS: 5.5 2025-06 — NPS: 5.1 2025-07 — NPS: 0.3 2025-08 — NPS: 6.3 2025-09 — NPS: 8.3 2025-10 — NPS: 2.8 2025-11 — NPS: 6.7 2025-12 — NPS: 6.3 2024-07 2024-10 2025-01 2025-04 2025-07 2025-10 Month NPS
Key takeaways
  • NPS peaks at +12.9 in 2024-10 and bottoms at −1.8 in 2024-09 — a ~15-point range.
  • Average NPS over 18 months hovers near zero (≈ +5.2) — customers are neutral rather than promoters; this is room to grow.

NPS by driver

NPS by survey driver. App quality and product pull up; fees and onboarding pull down.

-60 -50 -40 -30 -20 -10 0 10 20 30 40 app_quality — NPS: 30.3 30.3 product — NPS: 29.4 29.4 trust — NPS: 12.5 12.5 support — NPS: 9.2 9.2 onboarding — NPS: -23.6 -23.6 fees — NPS: -59.4 -59.4 app_quality product trust support onboarding fees Driver NPS
Key takeaways
  • App quality (+30.3) and product (+29.4) are the strongest drivers; fees (−59.4) is the main source of dissatisfaction.
  • Onboarding (−23.6) drags NPS down — consistent with the KYC bottleneck from Project 1.
