Formulas

The Friendship Maintenance Effort Calculator uses the following formula:

• Effort Score = \( \left(C \times E \times S\right) \times 100 \)
• Where:
  • \( C = \min\left(\frac{\text{Weekly Contact Hours}}{10}, 1\right) \) (max 10 hours)
  • \( E = \min\left(\frac{\text{Annual Shared Events}}{12}, 1\right) \) (max 12 events)
  • \( S = \frac{\text{Support Provided (%)}}{100} \)

How to Use

1. Enter the weekly contact hours in the “Weekly Contact Hours” field.
2. Enter the number of annual shared events in the “Annual Shared Events” field.
3. Enter the percentage of support provided in the “Support Provided (%)” field.
4. Optionally, use the activity buttons to focus on maintenance activities (e.g., Calls).
5. Click “Calculate Effort Score” to see your results.
6. Scroll to the “Results” section for detailed calculations.
7. Use the share buttons to share your effort score or embed the calculator.

Examples

1. Example 1: Contact = 5, Events = 6, Support = 80%
   Effort Score = \( \left(\min\left(\frac{5}{10}, 1\right) \times \min\left(\frac{6}{12}, 1\right) \times \frac{80}{100}\right) \times 100 = (0.5 \times 0.5 \times 0.8) \times 100 = 20.0\% \)
2. Example 2: Contact = 8, Events = 10, Support = 90%
   Effort Score = \( \left(\min\left(\frac{8}{10}, 1\right) \times \min\left(\frac{10}{12}, 1\right) \times \frac{90}{100}\right) \times 100 = (0.8 \times 0.833 \times 0.9) \times 100 = 60.0\% \)
3. Example 3: Contact = 2, Events = 3, Support = 50%
   Effort Score = \( \left(\min\left(\frac{2}{10}, 1\right) \times \min\left(\frac{3}{12}, 1\right) \times \frac{50}{100}\right) \times 100 = (0.2 \times 0.25 \times 0.5) \times 100 = 2.5\% \)
