Astrology enthusiasts often look for tools that can help them understand the deeper spiritual and karmic connections between two people. One such important point in synastry is the Vertex. Known as the “fated point” in astrology, the Vertex is believed to signify encounters and relationships that feel destined.
Vertex Synastry Calculator
What is the Vertex in Astrology?
The Vertex is not a planet but a calculated point in an astrological chart, usually located in the 5th, 6th, 7th, or 8th house. Astrologers often describe it as the “point of fate” or “point of destiny.” When another person’s planet touches your Vertex, the connection often feels significant, fated, or karmic in nature.
For example:
- Someone’s Sun on your Vertex may bring illumination and personal growth.
- Someone’s Venus on your Vertex could signify a destined romance.
- Someone’s Saturn on your Vertex may bring lessons, responsibility, or karmic ties.
This is where the Vertex Synastry Calculator becomes a valuable tool – it allows you to instantly measure whether two points are making meaningful aspects.

How to Use the Vertex Synastry Calculator
Using this tool is simple and does not require advanced astrology software. Follow these steps:
- Find the Vertex of Person 1
- Use a free natal chart calculator to find the exact degree of the Vertex (e.g., 134.5°).
- Find the Planet or Point of Person 2
- Identify the degree of the planet or point you want to test against Person 1’s Vertex (e.g., Person 2’s Venus at 136°).
- Enter the Values
- In the calculator, input Person 1’s Vertex, Person 2’s planet degree, and orb allowance (default is 3°).
- Click “Calculate”
- The calculator instantly shows the angular difference and whether there is a meaningful aspect.
- Interpret the Result
- If it shows “Conjunction,” it means Person 2’s planet is within the allowed orb of Person 1’s Vertex.
- The result may also show Sextile (60°), Square (90°), Trine (120°), or Opposition (180°) depending on alignment.
Example of Vertex Synastry Calculation
Let’s say:
- Person 1 has a Vertex at 145°
- Person 2 has Venus at 147°
- Orb set to 3°
Step 1: Enter Vertex = 145, Venus = 147, Orb = 3.
Step 2: The difference is 2°.
Step 3: Since the difference is less than 3°, the result shows:
👉 Angular Difference: 2°
👉 Synastry Result: Conjunction
This suggests a strong karmic and potentially romantic connection between the two.
