Formula Used
This calculator uses a weighted scoring model. It does not claim to predict a relationship. It creates a symbolic compatibility estimate for reflection.
Total Score =
Cross Aspect Score × Focus Weight + Element Score × Focus Weight + House Score × Focus Weight + Modality Score × Focus Weight + Planet Blend Score × Focus Weight + Timing Score × Focus Weight
- Cross Aspect Score: compares Person A Mars to Person B Venus, and Person A Venus to Person B Mars.
- Element Harmony: compares Fire, Earth, Air, and Water compatibility between cross placements.
- House Activation: scores the relationship themes shown by the selected houses.
- Modality Rhythm: compares Cardinal, Fixed, and Mutable styles.
- Planet Blend: reviews Mars to Mars and Venus to Venus links.
- Timing Confidence: adjusts confidence using birth time accuracy and retrograde selections.

Mars and Venus Compatibility Guide
What Mars and Venus Mean
Mars and Venus show two simple relationship themes. Mars describes action, desire, chase, courage, and direct style. Venus describes affection, pleasure, values, charm, and receiving love. When these two planets connect well between two charts, attraction can feel easy. When they clash, the bond can still be exciting, but it may need patience.
Why the Score Has Layers
This calculator turns those symbolic links into a structured score. It compares signs, elements, modalities, houses, degrees, and major aspects. It also lets you adjust the orb, relationship focus, and retrograde status. The result is not a rule about love. It is a reflection tool. Use it to notice patterns, questions, and possible growth areas.
Elements and Modalities
Element matching is the first layer. Fire often sparks air. Earth often supports water. Same elements feel familiar. Mixed elements may need translation. Modality matching is another layer. Cardinal signs initiate. Fixed signs stabilize. Mutable signs adapt. A couple with different modes can balance each other, if both respect the rhythm.
Aspects and Houses
Aspects add more detail. A conjunction can create strong pull. A trine can feel smooth and natural. A sextile can show friendly chemistry. A square can add friction and heat. An opposition can create fascination through contrast. Houses show where attraction lands in daily life. Fifth house links may feel playful. Seventh house links may feel committed. Eighth house links can feel intense. Eleventh house links often start as friendship.
Reading the Result
No score should replace communication. A lower score does not mean failure. It can show where clearer expectations are needed. A higher score does not guarantee trust, kindness, or maturity. Real compatibility grows through choices, timing, shared effort, and honest care.
Best Practice
For best results, enter exact degrees when available. If you only know the sign, use the default midpoint. Compare several scenarios. Read the notes, not only the number. The strongest value comes from using the score as a conversation starter. Ask what feels true. Ignore what does not fit. Let the calculator support awareness, not control your decisions. A good reading also accepts nuance. People change, and relationships change. Use the house notes to name situations, then use the aspect notes to understand the emotional tone behind them more clearly.
FAQs

2. Is the result a final relationship prediction?
No. The score is symbolic and educational. Real relationships depend on trust, timing, communication, maturity, values, and daily choices.
3. Do I need exact birth times?
Exact times improve house accuracy. Sign and degree comparison can still work without exact times. Use the birth accuracy option honestly.
4. What does Mars represent?
Mars represents desire, pursuit, courage, action, conflict style, and physical energy. In compatibility, it shows how someone moves toward attraction.
5. What does Venus represent?
Venus represents affection, pleasure, beauty, values, romance, and receiving love. In compatibility, it shows what feels attractive and sweet.
6. Which aspects are best for attraction?
Conjunctions, trines, and sextiles often feel easier. Oppositions can feel magnetic. Squares can create heat, but they need patience.
7. Why does the orb matter?
The orb controls how close an aspect must be. A smaller orb is stricter. A wider orb allows softer or less exact links.
