Sources and method.

Our data is anonymised ChartKit product analytics, September to October 2026. Research links open the original source. Estimates show their method.

  1. 1Our dataEdits to placed charts. 149 edits to 14 slide charts, 13 to 26 September 2026. Anonymised ChartKit product analytics.
  2. 2ResearchWhy each edit is a rebuild. In Google Slides, think-cell charts arrive as images and their data is deleted. think-cell KB0224
  3. 3EstimateHours saved. 149 edits × 5 minutes assumed = 12.4 hours, worth about €950 at €77 an hour.
  4. 4ResearchHourly cost, €77. The US employer cost for management, business and financial roles, $88.63 an hour, about €77. BLS, September 2026
  5. 5EstimateBoard-pack retyping saved per person. 2 hours a month refreshing a board pack by hand (assumed, the low end of the 2 to 8 hours our value audit used) × 12 months × €77 an hour = €1,848. Applies to charts linked to a Sheets range.
  6. 6ResearchValues copied by hand. About 3 in 100 are wrong. A clinical proxy, not a finance study. JAMIA re-keying study
  7. 7ResearchAutomating deck refreshes. Teams pay a median $9,000 a year. Vendr on Rollstack
  8. 8ResearchAI drafting and email time. In a field experiment with 7,137 workers, AI drafting cut email time by 1.4 hours a week. It measured Microsoft Copilot, not ChartKit. arXiv 2504.11436
  9. 9EstimateCarry-over. Takes the study's 1.4 hours a week and assumes it carries over to drafting in Slides and Docs.
