These numbers are not a promise of savings. They show what even small improvements in meeting quality can be worth over time. The more employees and meetings you have, the bigger the effect.
Salary basis: Statistics Norway table 11418, average monthly salary for full-time employees by industry. Hourly cost = monthly salary × 12 ÷ 1,695 effective working hours, plus 40 % for employer's social security contributions, holiday pay and pension. Meeting load is set per industry: 17–20 % for knowledge-intensive sectors such as IT, finance and the public sector, and 9–10 % for more operational sectors such as healthcare, construction, manufacturing and retail. No Norwegian statistics break meeting time down by industry, so these are estimates based on international studies (Bain/HBR, Microsoft Work Trend Index). On top of that we add 20 % for preparation before and refocusing after meetings – a deliberately conservative estimate, roughly 10 minutes per meeting hour. The improvement estimates are deliberately cautious: shorter meetings are set at 8 % and fewer meetings at 12 % of total meeting cost. Better decisions and follow-up recover part of the estimated waste – 25 % when few meetings could be better, rising gradually towards 45 % as the share approaches 60 % or more, because the potential is largest where the problem is largest.
