Excel Speed Loop

Excel Speed Loop

The Excel Speed Loop is the method that helped me reduce the time to update my workbooks from 2 weeks per month to 2 days per month.

I was an accountant in industry, sitting in my cube updating tons of Excel workbooks. I was stressed out and cranky because I had more work than time. I worked late nights and weekends and often felt anxious at work and home. I developed an informal system and a variety of Excel skills that helped me get my work done faster. I have formalized the method (aka framework, approach, system, process, cycle), and call it the Excel Speed Loop.

The Speed Loop is what I used to get my schedule under control, feel relaxed at work, and have a better work/life balance. What used to take 2 weeks per month was now getting done in 2 days, and I had more time than work.

I teach this method free, and I hope it can help you as well. Here is a quick overview.

Investor Mindset

I use an investor metaphor to teach the Speed Loop. An investor makes a financial investment, hopes the asset appreciates in value, and expects to realize a gain upon sale. That is, the investor seeks to get more back than what was invested.

Here, we are investing time (precious resource), appreciating the assets (improving our workbooks), and expecting to realize a gain (saving more time than invested).

This investor mindset helps keep us focused on the task at hand: improving our recurring-use Excel workbooks to save time and get our work done faster each period.

Invest Time

Our goal here is to locate our recurring-use workbooks and prepare them for the Speed Loop.

  • Identify – recurring project workbooks (these can provide future efficiency dividends)
  • Insert – lead sheets (a set of standard worksheets)

Appreciate Assets

Our goal here is to incrementally improve the workbooks over several cycles

  • Automate – manual update tasks based on current Excel skills
  • Anticipate – errors and prevent and/or detect them
  • Accumulate – additional Excel skills needed to automate more tasks next period

Realize Gain

Our goal here is to leverage our time savings and reinvest our efficiency dividends

  • Rebuild – the set of workbooks as a whole, from scratch
  • Reinvest – locate the next set of recurring project workbooks, and go around again

Free Webinar + Implementation Guide + Excel Template

If you’d like to dig into the details, I actually teach the Speed Loop free in a pre-recorded webinar.

The webinar is a better format for teaching because I can talk about the steps in detail and share my screen to demonstrate.

Plus, I actually take a sample workbook and go through several automation steps: centralizing input cells, converting ordinary ranges to tables, converting static values to formulas, converting formula-reports to PivotTables, and converting manual copy/paste with Power Query.

It is super fun, and the details really make the Speed Loop more concrete and easy to understand.



The complimentary 1-hour webinar provides step-by-step “how to” instructions with Excel demonstrations. The handouts include the Speed Loop Implementation Guide (PDF) as well as the Excel Lead Sheets Template (xlsx workbook) which you can swipe and adapt to your situation.
