Divisional charts, or vargas, are the sixteen charts of classical Vedic astrology derived by subdividing each sign of the birth chart into smaller parts, each assigned to a life area such as marriage, career, children or wealth. The main rashi chart is the first of the sixteen and shows the broad promise; the other fifteen refine it, and the Navamsa (D9) matters most.
The set is also called the shodashavarga (षोडशवर्ग, "sixteen divisions"), D-charts or divisional horoscopes. They are layers of one horoscope, not separate horoscopes with different predictions, and a serious reading of any major life question consults the relevant varga rather than the rashi alone.
Each divisional chart magnifies one slice of the rashi chart into a reading of its own.
The rashi chart is too coarse an instrument for the range of questions a serious consultation is asked to answer. Brihat Parashara Hora Shastra, the foundational classical text on this system, sets out sixteen divisions of the zodiac precisely for that reason. Marriage, profession, children, longevity and the state of the inner life each get their own division, and the classical method is to consult the rashi first for the broad picture and then the relevant varga for depth on the specific matter at hand. A planet that looks strong in the rashi chart alone can look considerably weaker, or stronger, once its divisional placement is added to the reading, which is why an astrologer working seriously rarely stops at the twelve-house chart.
How is a divisional chart calculated?
Every varga is calculated the same way: divide a thirty-degree sign into N equal parts and assign each part its own sign by a fixed rule. A planet's divisional placement therefore depends on its exact degree within the sign, not the sign alone. Two planets in the same rashi sign but at different degrees can land in different varga signs, and this sensitivity to precise degree is what gives the divisional system its resolving power.
It is also why an accurate birth time matters more for some vargas than others. The Shashtiamsa (D60), which changes every thirty arc-minutes, demands far tighter precision than the Hora (D2), which changes every fifteen degrees. Charts on this site use the Lahiri ayanamsha and the Swiss Ephemeris (/transparency).
Why is the Navamsa (D9) the most important varga?
The Navamsa carries unusual weight because it reads both marriage and the deeper dharmic orientation of a life, the two matters the tradition treats as most consequential to how a life unfolds. It divides each sign into nine parts of 3°20′. Its influence extends beyond its own subject: a planet's Navamsa placement is one of the standard tests of that planet's overall strength, alongside its rashi placement, and the concept of vargottama, a planet occupying the same sign in both the rashi and the Navamsa, is drawn from this chart. Navamsa (D9) Chart: How It Reads Marriage and Dharma works through its construction and reading in full.
How do you construct the Navamsa? A worked example
The Navamsa count starts from a different sign depending on whether the parent sign is movable, fixed or dual. Movable signs (Aries, Cancer, Libra, Capricorn) count from the sign itself; fixed signs (Taurus, Leo, Scorpio, Aquarius) count from the ninth sign from it; dual signs (Gemini, Virgo, Sagittarius, Pisces) count from the fifth sign from it.
Take the Sun at 28° Leo. Leo is a fixed sign, so the count of nine 3°20′ divisions begins from the ninth sign counted forward from Leo, which is Aries. Twenty-eight degrees falls in the ninth of the nine divisions (the eighth division ends at 26°40′, and the ninth runs from there to 30°). Counting nine signs forward from Aries (Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius) lands on Sagittarius, ruled by Jupiter. The Sun's Navamsa here is Sagittarius, not Leo, so this Sun is not vargottama. For a fixed sign such as Leo, vargottama falls in the fifth division, from 13°20′ to 16°40′; a movable sign is vargottama in its first division and a dual sign in its last.
What does each divisional chart read?
Each division has its own classical subject, and the table above lists all of them. The Saptamsa (D7) divides each sign into seven parts and is read for children and the affairs of progeny, with Jupiter as its natural significator. The Shodasamsa (D16) divides into sixteen parts of 1°52′30″ and reads material comfort: historically vehicles, more broadly the whole texture of a household's ease.
The Trimshamsa (D30) divides each sign into unequal Parashari segments rather than equal ones and is read for adversity and health pressure, using only five sub-rulers (Mars, Saturn, Jupiter, Mercury and Venus) rather than all nine grahas. The Shashtiamsa (D60), dividing each sign into sixty parts of just thirty arc-minutes, is the most refined of the standard divisions and is read, in the older tradition, for the karmic substrate a life carries in from before birth. The classical sources themselves caution that this reading requires birth-time precision most modern records cannot supply.
The Hora (D2) is read for wealth, splitting each sign into its first and second halves and assigning each to the Sun or Moon depending on the sign's gender in the classical scheme. The Drekkana (D3) reads siblings and courage. The Dasamsa (D10), one of the most consulted vargas after the Navamsa, reads career and public standing; see Dasamsa D10 Chart: How to Read It for Career. The Dvadasamsa (D12) reads the parents, and the Vimshamsa (D20) reads spiritual practice and devotional temperament. The remaining higher divisions, Chaturvimshamsa (D24) for learning, Saptavimshamsa (D27) for constitutional strength, and Khavedamsa (D40) and Akshavedamsa (D45) for general life effects, are consulted less often in ordinary practice but keep their place in the full shodashavarga system.
How do you read several vargas together?
You read the vargas together, never one in isolation. The classical method assesses a planet's strength across several vargas at once, a technique called vimshopaka bala, which weights a planet's dignity in each division and sums the result into a single strength score.
In ordinary consultation, the more common practice is narrower: for a marriage question, read the rashi seventh house alongside the Navamsa seventh house and its lord; for a career question, read the rashi tenth house alongside the Dasamsa; for a health or adversity question, bring in the Trimshamsa. Reading the vargas together rather than reaching for one in isolation is what separates a considered reading from a superficial one, and it is the habit the older commentators return to most often.
What are the common mistakes when reading divisional charts?
Three mistakes recur often enough in casual practice to name directly.
The first is treating a divisional chart as one that overrides the rashi rather than refines it. If the rashi looks difficult but the relevant varga looks strong, the temptation is to discard the rashi reading entirely. The classical method reads the two together, with the rashi giving the outer circumstance and the varga the finer texture.
The second is applying a varga outside its assigned subject, asking the Navamsa about career when the Dasamsa is the chart built for that question. Each division has a specific classical scope, and a reading that ignores it produces confident conclusions the chart was never built to support.
The third is skipping the divisional charts when birth time is uncertain. An approximate time is good enough for the rashi in most cases, since sign boundaries are thirty degrees wide, but several vargas divide those thirty degrees into far narrower slices, and a placement near a division boundary can flip to the neighbouring sign on a correction of only a few minutes. The honest response is to flag which placements sit close to a boundary and treat those as provisional until the time is confirmed.
What do the vargas add that the rashi cannot?
They show how, and how fully, the rashi's promise is lived out. A rashi tenth house that looks strong for career can be read with more confidence once the Dasamsa confirms it, or with appropriate caution once the Dasamsa reveals friction the rashi alone did not show. A rashi fifth house that looks constrained for children can be read with more nuance once the Saptamsa is brought in alongside it. None of the sixteen is a substitute for patient reading of the whole chart, and none delivers a verdict on its own.
How to find your divisional charts
You can place any planet in a divisional chart in four steps, and the Navamsa is the best first one.
Enter your birth date, time and place in the Lagna calculator to get the sign and degree of your Lagna and every planet.
Choose the varga and divide the planet's degree within its sign by the arc per part from the table above. Round up to get the division number.
Find the starting sign. For the Navamsa: movable signs count from themselves, fixed signs from the 9th sign from them, dual signs from the 5th. For the Dasamsa: odd signs count from themselves, even signs from the 9th.
Count forward from the starting sign by the division number, counting the starting sign as 1.
Doing this for sixteen charts by hand is the kind of arithmetic a calculator removes. The full reading at /kundli/new computes your Navamsa, Dasamsa and the other principal divisions alongside your rashi chart. For the order in which to read them, see How to Read a Vedic Birth Chart.
Frequently asked questions
What are divisional charts (vargas) in Vedic astrology?
Divisional charts are supplementary charts derived by subdividing each sign of the main birth chart into smaller equal (or, for the Trimshamsa, unequal) parts. Classical texts describe sixteen including the rashi, each assigned to a life area such as marriage, career or children, and each read alongside the main chart rather than in place of it.
How many divisional charts are there in Vedic astrology?
The classical shodashavarga has sixteen charts, counting the rashi chart (D1) as the first, so fifteen supplementary divisional charts sit alongside it. Software often shows only a subset, and a few later texts describe more divisions, but the sixteen are the standard Parashari set.
Which divisional chart is the most important?
The Navamsa (D9) is generally treated as the most important after the rashi chart itself, since it is read for both marriage and the deeper dharmic direction of a life, and it also serves as a general test of planetary strength. The Dasamsa (D10) for career is the next most consulted in ordinary practice.
How do you calculate a divisional chart?
Each division has its own rule for how many equal parts it splits a sign into and which sign each part is assigned to. The Navamsa splits each sign into nine parts of 3°20′, and the starting sign for the count depends on whether the parent sign is movable, fixed or dual. Each varga's construction rule is specific to that chart.
Do I need my exact birth time to read divisional charts?
Yes, more so than for the rashi chart. Divisional placements depend on a planet's precise degree within its sign, so even a small birth-time error can shift a planet into a different divisional sign. For finely divided charts like the Shashtiamsa (D60), the required precision is measured in seconds rather than minutes.
What is vargottama?
Vargottama describes a planet that occupies the same sign in both the rashi chart and the Navamsa. It falls in the first Navamsa of a movable sign, the fifth of a fixed sign and the last of a dual sign. It is read as a strengthening condition, since the outer and inner placements agree, though it does not override other afflictions a planet carries.
