Definition:
Return on Investment (ROI) measures the profitability of a project by comparing the net benefits (gains – costs) to the total costs. It tells you whether a project is worth pursuing and how much value it generates. Learn more about tracking projects here. 

How to Use It:
Enter your project cost (the total investment) and expected return (the total gain from the project). The calculator will compute your ROI as a percentage.

Example:

• Project Cost: $25,000 
• Expected Return: $40,000 
• ROI = (40,000 – 25,000) ÷ 25,000 × 100 = 60%
  👉 This means the project generates 60 cents of profit for every dollar invested.

Definition:
Inventory Turnover is a financial ratio that shows how many times a company sells and replaces its inventory during a period. A higher turnover means inventory is moving quickly, while a lower turnover may indicate overstocking or weak sales.

How to Use It:
Enter your Cost of Goods Sold (COGS) and your Average Inventory (beginning inventory + ending inventory ÷ 2). The calculator will give you the turnover ratio.

Example:

• COGS = $500,000 
• Average Inventory = $100,000 
• Inventory Turnover = 500,000 ÷ 100,000 = 5
  👉 This means the business sold and replenished its inventory 5 times during the period.

Exit Readiness Calculator – Scorecard Style
Are you ready to sell your business? This calculator helps you assess how prepared your company is for a successful exit. It looks at four key areas buyers care about: profitability, 

systems, revenue diversification, and leadership.

Definition:
Exit readiness measures how attractive and prepared your business is for a buyer or investor. It gives you a simple score to show whether you’re on track or need more preparation.

Formula:
We score each area from 1 to 5. Then:

👉 Total Score = Profitability + Systems + Diversification + Team
👉 Readiness % = (Total Score ÷ 20) × 100

Example:
If you rate your business as:

• Profitability = 4 
• Systems = 3 
• Diversification = 5 
• Team = 4
   

👉 Total Score = 4 + 3 + 5 + 4 = 16
👉 Readiness % = (16 ÷ 20) × 100 = 80%
👉 This means your business is highly exit-ready.

Project Timeline Estimator

Definition:
Helps managers quickly estimate how long a project will take based on tasks, dependencies, and team capacity. Useful for planning and resource allocation. Learn more about tracking projects here.

How it works:

• Inputs: 
  • Number of tasks or phases 
  • Estimated duration per task 
  • Number of team members assigned 
  • Dependencies (e.g., Task B starts after Task A)
     
• Outputs: 
  • Estimated project completion date

We account for the number of team members assigned. More people can finish faster (assuming work can be parallelized).

 Adjusted Duration (days) = Original Task Duration (days)​  / Number of Team Members Assigned 

• Example: 
  • Task: “Write Report” 
  • Original Duration: 6 days 
  • Team Members: 2 

Adjusted Duration = 6 ÷ 2 = 3 days

Sum the adjusted durations of all tasks (assuming tasks are sequential, not overlapping).

• Example: 
  • Task 1: 3 days 
  • Task 2: 2 days 
  • Task 3: 4 days 

Total Duration = 3 + 2 + 4 = 9 days

Percent Increase & Decrease Calculator

Definition & How to Use:

Quickly calculate how much a value has increased or decreased in percentage terms. Enter the original value and the new value, and the calculator will show the percent change. Positive values indicate an increase, negative values indicate a decrease.

Formulas:

Percent Increase: Percent Increase  (%) = (New Value − Original Value) / Original Value × 100

Percent Decrease: Percent Decrease (%) = (Original Value − New Value) / Original Value ×  100

Combined Formula (shows positive for increase, negative for decrease): 

Percent Change (%) = New Value − Original Value

Example:

• Original Value = 50 
• New Value = 75 
• Percent Change = (75−50) / 50∗100 = 50% increase

Employee Productivity Calculator

Definition:
This calculator measures the average output per employee, factoring in the number of shifts and workforce efficiency. It helps CEOs and managers evaluate productivity, identify bottlenecks, and optimize team performance.

How It Works:

1. Enter the total output produced by employees. 
2. Enter the number of employees. 
3. Enter the number of shifts worked. 
4. Enter the efficiency factor (%) to account for real-world performance.
    
5. Click Calculate to see: 
   • Base productivity per employee (without adjustments) 
   • Adjusted productivity per employee per shift, accounting for efficiency and multiple shifts
      

Formulas:

• Base Productivity per Employee: 

Base Productivity = Total Output / Number of Employees

• Adjusted Productivity per Employee per Shift: 

Adjusted Productivity = Base Productivity × (Efficiency/100) / Number of Shifts

Example:

• Total Output = 10,000 units 
• Number of Employees = 50 
• Number of Shifts = 2 
• Efficiency Factor = 90%
   

Base Productivity: 10,000 ÷ 50 = 200 units per employee
Adjusted Productivity: (200 × 0.9) ÷ 2 = 90 units per employee per shift
