These 12 Customer Feedback KPIs were selected to provide a comprehensive view of customer experience performance, balancing leading indicators like Customer Effort Score (CES) with lagging outcomes such as Customer Retention Rate and Customer Churn Rate. The set spans operational metrics (First Contact Resolution, Customer Complaints) and sentiment measures (Net Promoter Score, Positive Feedback Rate), ensuring coverage across feedback collection, resolution, and loyalty impact.

Track Net Promoter Score alongside Customer Retention Rate to detect loyalty shifts; a declining NPS with stable retention suggests emerging dissatisfaction not yet causing churn. Monitor Customer Effort Score in tandem with First Contact Resolution—high CES with low FCR signals friction in issue resolution processes. Compare Feedback Response Rate against Customer Feedback Loop Completion Rate to identify gaps in closing the feedback cycle, which can undermine trust and future engagement.

Prioritize Net Promoter Score and Customer Retention Rate first, as these KPIs are widely tracked and offer immediate insight into overall customer loyalty and business impact. Follow with Customer Effort Score to diagnose friction points in service interactions. This sequence leverages available data while layering diagnostic depth. The full Customer Feedback KPI set, including advanced operational and sentiment metrics, is accessible in the KPI Depot database.

FAQs about KPI Depot


What does unlimited web access mean?

Our complete KPI and benchmark database is viewable online. Unlimited web access means you can browse as much of our online KPI and benchmark database as you'd like, with no limitations or restrictions (e.g. certain number of views per month). You are only restricted on the quantity of CSV downloads (see questions below).

What's the difference between the Basic and Pro plans?

Both plans include unlimited web access to the full KPI database and benchmark database, interactive Strategy Maps for every KPI group, and 2,000+ OKR examples.

The Basic plan includes 5 CSV downloads per month and is designed for individual research use.

The Pro plan includes 20 CSV downloads per month and unlocks the full deliverable workflow: save your customized Strategy Maps and export them as Balanced Scorecard CSV templates, complete with KPI names, formulas, monthly tracking columns, and links to benchmark data. Open the export in Excel and start tracking immediately.

Can I try the interactive Strategy Map before subscribing?

Yes. Every KPI group includes an interactive Strategy Map that anyone can open, no subscription required. You can add, remove, and rearrange KPIs across the 4 Balanced Scorecard perspectives (Financial, Customer, Internal Process, and Learning & Growth) to build a map tailored to your organization.

Saving your customized map and exporting it as a Balanced Scorecard CSV template are Pro plan features. To help you turn that CSV into a polished, ready-to-track scorecard, we also offer 5 free Balanced Scorecard Excel templates that pair with your export.

Can I download KPI group data as a CSV?

Yes. You can download a complete KPI group (which includes all inclusive KPIs and respective attribute data) as a CSV file. To gain a better sense of the KPI data included, you can download a sample CSV file here.

Can I download benchmark data as a CSV?

Yes. On individual KPI pages, you can download all available benchmarks for that KPI as a CSV file. To gain a better sense of the benchmark data included, you can download a sample CSV file here.

Each CSV download, whether for a KPI group or for benchmarks, consumes 1 of your monthly CSV download credits.

What if I need more CSV downloads in a month?

You can purchase additional download credits at any time: $8 each on the Basic plan, $5 each on the Pro plan. Credits never interrupt your workflow, so you'll never be locked out of a download you need mid-project.

How does KPI Depot pricing compare to other benchmark data sources?

Benchmark data is traditionally expensive. Subscription research and advisory services typically run $2,400 to $70,000+ per year, and a single benchmarking assessment can cost $5,000 at nonmember rates. Compiling benchmarks yourself from public sources takes weeks of analyst time per project.

KPI Depot includes unlimited web access to all 35,625 source-attributed benchmarks on every plan, starting at $499 per year. Each benchmark documents its source, company size, time period, industry, geography, and sample size, so your targets hold up under scrutiny.
