These 12 KPIs were selected from the ISO 50001 KPI database to provide a balanced view of energy management performance. They combine operational metrics like Total Energy Consumption and Peak Demand Reduction with financial indicators such as Total Energy Cost Savings and Energy Saving Investment Return. This subset spans leading and lagging indicators, enabling comprehensive tracking of energy efficiency, cost control, and environmental impact within ISO 50001 frameworks.

Track Energy Performance Improvement alongside Energy Intensity Reduction to assess efficiency gains relative to production scale. A rising Energy Consumption per Unit of Production with flat or declining Energy Performance Improvement signals operational inefficiencies despite overall energy savings. Monitor Total Energy Cost Savings in parallel with Energy Cost as a Percentage of Total Operating Costs—divergence here may indicate shifting cost structures or hidden energy waste. CO2 Emissions Reduction correlates closely with improvements in Energy Performance and Total Energy Consumption, confirming environmental impact alongside financial outcomes.

Prioritize establishing the Energy Use Baseline and Energy Audit Completion Rate first to ground all subsequent KPIs in accurate, current data. Next, implement Energy Performance Improvement and Total Energy Cost Savings to measure efficiency gains and financial impact directly. These KPIs provide immediate diagnostic value and are typically accessible from existing energy management systems. The full ISO 50001 KPI set, with detailed formulas and benchmarks, is available 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 34,632 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.

Can I cancel at any time?

Yes. You can cancel your subscription at any time. After cancellation, your KPI Depot subscription will remain active until the end of the current billing period.

Do you offer a free trial?

While we don't offer a traditional free trial, we give you plenty of ways to evaluate KPI Depot before subscribing.
