Navamsa Chart (D9) Explained: How It Is Calculated, Vargottama and Why It Matters

Quick answer: The navamsa (D9) is a divisional chart in Vedic astrology made by splitting each 30-degree sign into nine equal parts of 3 degrees 20 minutes. Counting starts from Mesha for fire signs, Makara for earth signs, Tula for air signs and Karka for water signs, and continues in zodiac order. A planet's position in the navamsa is traditionally read for marriage, inner strength and the fruit of the birth chart's promise.

What the navamsa is

Your main birth chart, the rashi chart or D1, shows which of the twelve signs each planet occupied at birth. Parashari Jyotisha then refines this with divisional charts (vargas), which zoom in on a smaller slice of each sign. The navamsa, "ninth part", is by far the most widely used. Many astrologers will not finalise any judgement without looking at it, and Indian horoscope software prints it beside the D1 by default.

A useful link: one navamsa is exactly 3 degrees 20 minutes, the same span as one pada (quarter) of a nakshatra. There are 27 nakshatras times 4 padas, or 12 signs times 9 navamsas, which both make 108. So if you know the nakshatra and pada of a planet, you already know its navamsa: the four padas of Ashwini fall in the Mesha, Vrishabha, Mithuna and Karka navamsas, the padas of Bharani continue from Simha, and so on through the zodiac. See the 27 nakshatras guide for the star spans.

How navamsa signs are counted (the Parashari rule)

Each sign is cut into nine slices of 3 degrees 20 minutes. The first slice of a sign is assigned to a starting sign that depends on the sign's element, and the following slices continue in zodiac order:

An equivalent way to remember it: for a movable sign (Mesha, Karka, Tula, Makara), count from the sign itself; for a fixed sign (Vrishabha, Simha, Vrishchika, Kumbha), start from the 9th sign from it; for a dual sign (Mithuna, Kanya, Dhanu, Meena), start from the 5th sign from it. Both methods give identical results.

A third shortcut works from the planet's absolute (0 to 360 degree) longitude: divide it by 3 degrees 20 minutes, ignore the fraction, and take the remainder after dividing by 12. Remainder 0 is Mesha, 1 is Vrishabha, and so on.

Full navamsa lookup table

Find the planet's sign in the first column and its degree range across the top.

Notice the pattern: the zodiac's 108 navamsas simply run Mesha, Vrishabha, Mithuna and onward in an unbroken cycle, nine times through the twelve signs. Mesha's nine navamsas run from Mesha to Dhanu, Vrishabha's pick up at Makara, and so on.

Worked example

These are made-up positions for illustration, not a real chart.

• A planet at Simha 17 degrees 45 minutes. Simha is a fire sign, so counting starts from Mesha. 17 degrees 45 minutes falls in the slice 16 degrees 40 minutes to 20 degrees, the 6th navamsa. Counting six signs from Mesha (Mesha, Vrishabha, Mithuna, Karka, Simha, Kanya) gives Kanya navamsa. Check with the shortcut: Simha 17 degrees 45 minutes is 137.75 degrees of absolute longitude; divided by 3.333 that is 41.3, so 41; 41 divided by 12 leaves 5, which is Kanya.
• A planet at Vrishchika 2 degrees 10 minutes. Vrishchika is a water sign, so counting starts from Karka. 2 degrees 10 minutes is in the 1st slice, giving Karka navamsa.
• A planet at Kumbha 25 degrees. Kumbha is an air sign, so counting starts from Tula. 25 degrees is in the 8th slice (23 degrees 20 minutes to 26 degrees 40 minutes). Counting eight from Tula (Tula, Vrishchika, Dhanu, Makara, Kumbha, Meena, Mesha, Vrishabha) gives Vrishabha navamsa.

The navamsa lagna is found the same way from the ascendant's degree. Once every planet and the lagna have their navamsa sign, the D9 is drawn as an ordinary chart, in North or South Indian style, with houses counted from the navamsa lagna.

Vargottama: same sign in D1 and D9

When a planet or the lagna falls in the same sign in both the rashi and the navamsa, it is called vargottama. From the table you can see where this happens: the first navamsa of movable signs (for example Mesha 0 to 3 degrees 20 minutes), the fifth (middle) navamsa of fixed signs (for example Vrishabha 13 degrees 20 minutes to 16 degrees 40 minutes) and the ninth (last) navamsa of dual signs (for example Mithuna 26 degrees 40 minutes to 30 degrees). Traditionally, a vargottama planet is described as steady and strong, able to give the results of its sign more fully.

Why astrologers use the D9

In the traditional view, the navamsa does three main jobs:

• Marriage and partnership: the 7th house of the navamsa, its lord and Venus (and Jupiter, in some traditions) are read alongside the 7th house of the birth chart. This is why many families request the D9 during matching, in addition to Guna Milan or porutham.
• Strength of planets: a planet that looks weak in the D1 but is well placed in the D9 (for example in its own or exaltation sign) is said to recover strength, and vice versa. Some astrologers describe the D9 as showing a planet's inner, mature expression.
• Confirmation: a promise in the birth chart is often said to bear fruit more fully if the navamsa supports it. Hence the saying that the D1 is the tree and the D9 its fruit.

None of this is mechanical. Astrologers combine the D9 with the D1, the lagna and houses, the Vimshottari dasha running at the time and transits, and different schools weigh it differently. A navamsa placement is never, on its own, a forecast about whom or when you will marry.

Other divisional charts, briefly

The higher the division, the more sensitive the chart is to birth time. Many astrologers therefore rely mainly on the D1, D9 and D10 unless the birth time has been carefully verified.

Frequently asked questions

What is the navamsa chart used for?

In Vedic astrology the navamsa (D9) is traditionally consulted for marriage and partnership, for the deeper or inner strength of each planet, and as a check on promises seen in the main birth chart. Astrologers read it together with the rashi chart, never on its own.

How big is one navamsa?

One ninth of a sign: 30 degrees divided by 9 equals 3 degrees 20 minutes. The zodiac therefore has 108 navamsas, and each navamsa is exactly the same span as one nakshatra pada (quarter).

What does vargottama mean?

A planet or lagna is vargottama when it occupies the same sign in the rashi (D1) chart and the navamsa (D9) chart. This happens in the first navamsa of the movable signs, the fifth (middle) navamsa of the fixed signs and the last navamsa of the dual signs. Traditionally it is considered a sign of strength.

Why does my navamsa change with a small change in birth time?

The ascendant moves through a whole sign in roughly two hours on average, so it crosses a 3 degree 20 minute navamsa in roughly 13 minutes on average (faster or slower depending on the sign and your latitude). A small error in birth time can shift the navamsa lagna, though the planets, which move much more slowly, are usually unaffected.

Is the D9 more important than the birth chart?

Most astrologers say no. The rashi chart (D1) is the foundation, and the navamsa refines it. A common saying is that the D1 is the tree and the D9 is the fruit, but practitioners differ in how much weight they give each.

What are D10 and the other divisional charts?

Parashari astrology describes sixteen divisional charts (shodashavarga). Common ones include the D2 Hora (wealth), D3 Drekkana (siblings), D7 Saptamsha (children), D10 Dashamsha (career and public life), D12 Dwadashamsha (parents) and D60 Shashtiamsha. Each divides a sign into a different number of parts.

Editor's note (9 October 2026)

This explainer follows the standard Parashari navamsa rule (fire signs from Mesha, earth from Makara, air from Tula, water from Karka) used by Indian almanacs and software; the lookup table was generated from that rule and cross-checked against the movable, fixed and dual formulation. Positions are sidereal, normally with the Lahiri ayanamsa. Interpretive statements describe how practitioners traditionally use the D9 and vary between schools. The worked examples use invented positions. This is general information, not a personal reading.
