Enter the details for both people. The calculator compares the astrology factors available from the information entered and returns a compatibility percentage with a written breakdown.
What the Compatibility Calculator Compares
Each placement describes a different part of how two people may respond to each other. The result reads these areas separately before bringing them into one compatibility score.
Sun Sign Compatibility
The Sun sign relates to identity and personal direction. The comparison looks at where both people naturally understand each other and where their basic styles may clash.
Moon Sign Compatibility
The Moon sign relates to emotional safety and instinctive reactions. It can show differences in how each person responds to reassurance, silence, closeness, or stress.
Rising Sign Compatibility
The Rising sign, also called the Ascendant, relates to outward behaviour and first reactions. Comparing both Rising signs can give more context to everyday interaction.
Communication Patterns
The reading looks at how the pairing may speak through disagreement, explain feelings, respond to misunderstanding, and react when conversations become tense.
Attraction and Closeness
The result describes where affection may feel natural and where differences in emotional pace may create confusion between the two people.
Conflict Patterns
The comparison points to situations where tension may appear and describes how each person may react when pressure builds.

What Your Compatibility Result Means
Overall Compatibility Score
The percentage brings the factors used by the calculator into one summary result.
Areas That Feel Natural
The reading points to parts of the pairing where reactions and expectations may fit with less friction.
Areas Where Tension May Appear
The breakdown describes situations where emotional needs or communication habits may differ.
Relationship Context
The written reading explains what sits behind the percentage so the result is not only a number.
What the Compatibility Score Does Not Mean
A compatibility percentage does not predict whether two people will stay together or separate. Relationships also depend on behaviour, communication, personal values, circumstances, and the effort both people put into the relationship. The calculator should be read as an astrology based comparison of the information entered into the tool.

Common Questions
How does the zodiac compatibility calculator work?
The calculator compares the astrology information entered for both people and brings the factors used by the scoring system into one compatibility percentage. The result also explains what may feel natural between the pair and where differences may appear.
What do Sun Moon and Rising signs mean in compatibility?
The Sun relates to identity and personal direction. The Moon relates to emotional safety and instinctive reactions. The Rising sign, also called the Ascendant, relates to outward behaviour and first responses. Each describes a different part of how two people may interact.
Is birth time required?
Birth time becomes important when a calculation depends on the Rising sign or other time sensitive chart information. If exact birth time is unknown, the calculator should only use the factors that can be read from the information available.
How accurate is an astrology compatibility calculator?
The result should be treated as an astrology based interpretation rather than a prediction of relationship success. Real relationships are also shaped by behaviour, communication, values, and circumstances outside astrology.
What does the compatibility percentage mean?
The percentage summarises the astrology factors included in the calculator. The written breakdown explains which parts of the comparison contributed to an easier or more difficult match.
How is AI used in the calculator?
The current calculator uses its built-in scoring and analysis rules rather than AI to calculate the compatibility result. The score and written explanation are generated from the information entered into the tool.
