Calculated Part of Fortune
—Part of Fortune Formula:
The calculation for the Part of Fortune (PoF) is dependent on whether the native was born during the day or the night. This distinction determines which sign’s distance from the other is added to the Ascendant (ASC).
Day Chart (Diurnal):
$$ \text{PoF} = \text{ASC} + \text{Moon} – \text{Sun} $$
Night Chart (Nocturnal):
$$ \text{PoF} = \text{ASC} + \text{Sun} – \text{Moon} $$
Note: All results are taken modulo 360 degrees to place them within the zodiac circle.
Variables:
- Ascendant (ASC): The zodiac degree rising on the eastern horizon at the moment of birth. It represents personality and physical appearance.
- Sun Degree: The exact degree of the Sun’s placement in the natal chart. It represents ego, will, and life force.
- Moon Degree: The exact degree of the Moon’s placement in the natal chart. It represents emotions, habits, and instinct.
- Chart Type (Day/Night): Determined by whether the Sun is above (Day) or below (Night) the horizon at birth.

What is the Part of Fortune?
The Part of Fortune (sometimes called the Lot of Fortune) is calculated based on the relationship between the three main “lights” or points in a natal chart: the Sun (which signifies purpose), the Moon (which signifies emotion and need), and the Ascendant (which signifies the body and environment). The PoF symbolizes the area of life where the native can find natural harmony, material gain, prosperity, and personal fulfillment when integrating these three core energies.
In Hellenistic and Medieval astrology, the Part of Fortune was considered a primary indicator of wealth and worldly success. It is essentially an energetic point of synthesis. For instance, if the Sun is the “light” of action and the Moon is the “light” of emotion, the Part of Fortune shows where these two lights meet the horizon (the Ascendant), defining the native’s inherent capacity to be successful in the physical world.
How to Calculate Part of Fortune (Example):
- Identify the degrees: Assume a Night Chart with ASC at 220° (20° Scorpio), Sun at 85° (25° Gemini), and Moon at 30° (0° Taurus).
- Determine the Chart Type: It is a Night Chart (Sun below the horizon), so we use the Night Chart formula: $\text{PoF} = \text{ASC} + \text{Sun} – \text{Moon}$.
- Substitute values: $\text{PoF} = 220^\circ + 85^\circ – 30^\circ$.
- Calculate the sum: $220 + 85 – 30 = 275^\circ$.
- Final Result: $275^\circ$. Since $275^\circ$ is between $0^\circ$ and $360^\circ$, no modulo operation is needed. The Part of Fortune is at 5° Capricorn ($275 – 270$).
Frequently Asked Questions (FAQ):
What does the sign of the Part of Fortune mean?
The sign and house where the Part of Fortune falls indicates the manner and area of life through which you can most easily achieve happiness and material success. For example, PoF in Aries suggests self-starting action leads to prosperity, while PoF in the 2nd House suggests success through personal resources and values.
Does the Part of Fortune change for Day and Night Charts?
Yes, the formula is reversed. For a Day Chart ($\text{Sun}>\text{ASC}$), the formula is $\text{ASC} + \text{Moon} – \text{Sun}$. For a Night Chart ($\text{Sun}<\text{ASC}$), the formula is $\text{ASC} + \text{Sun} - \text{Moon}$. This reversal is critical for accurate traditional calculations.
Is the Part of Fortune a planet?
No, it is not a physical body (planet). It is a calculated, sensitive point in the chart, often referred to as a “lot” or “Arabic part,” which carries significant interpretive weight.
What is the maximum degree value I can enter?
You should enter a value between 0.00 and 359.99 degrees, representing the exact placement within the 360-degree zodiac wheel.
