#### Formulas Used

1. Admin Hours Saved / Year Hours_Saved = Employees × Admin_Hrs_Per_Week × 52 × (Time_Savings% ÷ 100)

2. Value of Time Saved Time_Savings_Value = Hours_Saved × Avg_Billable_Rate Assumes saved hours are redirected to billable work or business development.

3. Error & Rework Savings Error_Savings = Annual_Error_Cost × (Error_Reduction% ÷ 100)

4. Revenue Uplift from Improved Win Rate Win_Rate_Multiplier = (Current_Win_Rate + Improvement) ÷ Current_Win_Rate Revenue_Uplift = Annual_Revenue × (Win_Rate_Multiplier − 1)

5. Total Annual Benefit Total_Benefit = Time_Savings_Value + Error_Savings + Revenue_Uplift

6. Year-1 Total AI Cost Annual_AI_Cost = (Monthly_Subscription × 12) + Implementation_Cost

7. Year-1 ROI ROI = ((Total_Benefit − Annual_AI_Cost) ÷ Annual_AI_Cost) × 100

8. Payback Period Payback_Months = Implementation_Cost ÷ (Total_Annual_Benefit ÷ 12)

9. 3-Year Net Benefit 3-Year_Net = (Total_Benefit × 3) − Implementation_Cost − (Monthly_Sub × 12 × 3)
