How the Affinity Score Is Calculated
The calculator uses a weighted formula that combines three main components:
1. Name Similarity Score (40% weight)
The tool compares both names character by character. Each matching letter increases the score.
2. Age Compatibility Factor (30% weight)
Age difference affects compatibility. Smaller differences result in higher scores.
3. Shared Interests Score (30% weight)
User-provided interest similarity plays a major role in final results.
Affinity Formula Explained
The final affinity score is calculated using this formula:Affinity=(NameScore×0.4)+(AgeFactor×0.3)+(InterestScore×0.3)
Where:
- NameScore = Similar letters between both names
- AgeFactor = 100 – (Age difference × 5)
- InterestScore = User input (0–100)
Final Output:
- Rounded to nearest whole number
- Displayed as percentage (%)
Compatibility Levels Explained
The result is categorized into four levels:
| Affinity Score | Compatibility Level | Meaning |
|---|---|---|
| 80 – 100% | Excellent Match | Very strong connection |
| 60 – 79% | Good Match | Strong compatibility |
| 40 – 59% | Average Match | Moderate connection |
| 0 – 39% | Low Match | Weak compatibility |
This helps users quickly understand their result without needing complex interpretation.
Example Calculation
Let’s take an example:
- Name 1: Ali
- Name 2: Aisha
- Age 1: 25
- Age 2: 23
- Shared Interests: 80
Step-by-step breakdown:
Name Score:
Matching letters give a score of around 20%
Age Factor:
Age difference = 2
Age Factor = 100 – (2 × 5) = 90%
Interest Score:
80%
Final Calculation:
Affinity=(20×0.4)+(90×0.3)+(80×0.3)
= 8 + 27 + 24
= 59% Affinity Score
Result:
- Affinity Score: 59%
- Compatibility Level: Average Match
Factors That Influence Compatibility
1. Name Similarity
Shared or similar letters increase the match score slightly.
2. Age Difference
Smaller age gaps generally improve compatibility results.
3. Shared Interests
This is the most important real-world factor in the calculation.
4. Balance of Inputs
Even if one factor is strong, weak values in others can reduce the final score.
