Your scenario

Team size

25 people

Average hourly cost (fully loaded)

600 SEK/h

Manual process hours per person/week

8 hours

Expected automation rate

30 %

Error rate reduction

30 %

Average cost per error

5,000 SEK

Current errors per month

10 errors

Implementation cost (one-off)

500,000 SEK

NPV settings

Discount rate (NPV)

8 %

3,120 h

~1.7 FTE equivalent

Total annual benefit

2,052,000 SEK

1,872,000 SEK productivity + 180,000 SEK quality

Payback period

2.9 months

Excellent (<12 mo, Brealey/Myers/Allen rule)

3-year ROI / NPV

1,131%

NPV 4,788,203 SEK at 8%

Cumulative cashflow (36 months)

Bars dipping below zero are still paying off the implementation cost. Crossing zero = break-even.

Quality

Productivity (time) 91 %

Quality (error reduction) 9 %

Stream leverage

What happens to Annual Benefit when each stream swings ±20%. Inputs within a stream multiply, so a swing on any of the four productivity inputs (team, hourly cost, hours, automation rate) produces the same delta. That is a property of the formula, not a bug.

Productivity stream (team × hourly × hours × automation%) 748,800 SEK

Quality stream (errors × reduction% × cost-per-error) 72,000 SEK

Core formulas

Annual hours saved = team x weekly manual hours x automation% x 52 weeks. FTE conversion uses 1,800 productive hours per year as a directional baseline (52 weeks x ~35h, net of typical leave). Country-specific OECD figures vary; Sweden lands closer to ~1,440.
Annual cost savings = hours saved x hourly cost (fully loaded).
Annual error savings = errors per month x reduction% x cost per error x 12.
Risk-adjusted benefit = total annual benefit x scenario multiplier (-25% / 0% / +15%). Following Forrester's TEI principle of risk-adjusting benefit estimates; the specific bands are our convention, not a TEI-published table (Forrester applies study-specific adjustments).
Payback period = implementation cost / annual benefit, in months. Standard form, covered in Brealey, Myers & Allen ch. 5 alongside NPV.
3-year ROI (undiscounted) = ((3 x annual benefit - cost) / cost) x 100%. Standard introductory ROI formula.
3-year NPV = sum of (annual benefit / (1 + r)^t) for t = 1, 2, 3 minus initial cost. Brealey et al., chapters 5-6.

Default-value benchmarks

Average hourly cost (fully loaded) (default 600 SEK/h, range 200-2000 SEK/h): SCB Sweden tjänsteman wage statistics; 1.5x multiplier is our convention for fully loaded cost, not an SCB-published rule.
Manual process hours per person/week (default 8 hours, range 1-20 hours): Asana, Anatomy of Work Index 2023 (~4.9h/week recoverable; ~58% of day on work-about-work).
Expected automation rate (default 30 %, range 10-60 %): McKinsey Global Institute, A future that works (2017).
Error rate reduction (default 30 %, range 10-60 %): Deloitte, Intelligent Automation 2020 survey (qualitative quality improvement; 30% midpoint is our convention).
Discount rate (NPV) (default 8 %, range 4-15 %): HBR, A Refresher on Net Present Value (2014) for the NPV concept; the 6-10% WACC band is an industry rule of thumb, not from HBR.
