What is a Navamsa (D9) chart?

The Navamsa is the ninth of the Vedic divisional charts (vargas). Each 30-degree sign is split into nine equal parts of 3 degrees 20 minutes, and each part is assigned to a sign, so every planet gains a navamsa (D9) sign in addition to its main Rashi (D1) sign. Where the D1 describes the broad life, the D9 is the classic chart of marriage and the spouse, and is also used to judge the inner strength of each planet and matters of dharma.

The word navamsa means “ninth part” (nava = nine, amsa = part). In Hindi the chart is widely called the Navmansh Kundli; in Tamil, Navamsam or Navamsa Kattam; in Telugu, Navamsa Chakram.

How to read your Navamsa chart

Start with the Navamsa Lagna - the navamsa sign of your Ascendant - which anchors the D9 houses. Then look at each planet’s D9 sign and house in the table above, and compare it with the planet’s D1 sign. The starting sign of the nine navamsas depends on the nature of the sign: movable (cardinal) signs begin from the same sign, fixed signs from the 9th sign from it, and dual (mutable) signs from the 5th. Counting forward by the planet’s 3-degree-20-minute part gives its navamsa sign.

Two patterns are worth noting as you read: planets that are vargottama (same sign in D1 and D9), and the 7th house from the Navamsa Lagna for marriage themes. Both are surfaced automatically below the chart.

Navamsa Lagna and birth-time precision

The single most important caveat for any D9 chart is birth time. The Ascendant moves through the zodiac far faster than the planets, and it does so unevenly (oblique ascension), so the navamsa of the Lagna changes roughly every 13 to 14 minutes on average, and sometimes faster or slower depending on the rising sign and your latitude. By comparison, the main D1 Lagna changes only about every two hours.

Because of this, the tool computes how many minutes your entered birth time sits from the nearest Navamsa Lagna boundary. If that figure is small, even a few minutes of error in your recorded birth time could move your Navamsa Lagna - and the entire D9 house framework - into the adjacent sign, so it is worth verifying your time. If the figure is comfortable, small uncertainty is unlikely to change the result.

Vargottama: meaning and the honest base rate

A planet is vargottama when it sits in the same sign in both the D1 and the D9. Classical sources read this as a kind of steadiness or reinforced strength for that planet, because its expression is consistent across the two most-used charts.

It is worth being honest about how common this is. A planet returns to its own sign in the navamsa for 3 degrees 20 minutes out of every 30-degree sign, so the base rate is about 1 in 9 placements per planet. Finding a vargottama planet or two in a chart is therefore normal, not extraordinary; it is one factor among many, not a verdict.

Navamsa chart for marriage and the 7th house

The Navamsa is the classical chart of marriage and the spouse, read alongside the D1. Practitioners weigh the Navamsa Lagna, the 7th house from it, and the placement of Venus and Jupiter in the D9. This page surfaces those positions descriptively as a cultural reference; it does not predict marriage events.

For full matrimonial compatibility between two charts, the 36-point Ashtakoot Guna Milan is the standard framework - see our Kundli Matching tool, which scores both partners’ charts and flags any Bhakoot, Nadi, or Mangal Dosha at the same time.

Navamsa (D9) vs Rashi (D1): what the D9 adds

The Rashi (D1) chart, which you can generate with our Free Kundli Generator, is the primary chart of the whole life. The Navamsa refines it - a common maxim is that the D9 refines the D1, it does not override it. A planet may look strong in the D1 but be placed awkwardly in the D9, or the reverse, and the two readings are held together.

If you are still finding your Moon sign or Ascendant, the Rashi Calculator returns your Janma Rashi, Lagna Rashi, Nakshatra, and Pada from the same birth details this tool uses.

Frequently Asked Questions

What is a Navamsa (D9) chart?

The Navamsa, or D9, is the ninth divisional (varga) chart in Vedic astrology. Each 30-degree sign is divided into nine equal parts of 3 degrees 20 minutes, and each part maps to a sign, giving every planet a navamsa sign in addition to its main (D1 / Rashi) sign. The D9 is read alongside the D1, especially for marriage, the spouse, dharma, and the underlying strength of each planet.

What does a Navamsa chart show, and what does it mean?

A navamsa chart shows where each of your nine planets falls in the D9 (ninth-harmonic) division, plus the Navamsa Lagna. The meaning of the navamsa chart is read in two layers: the broad significations of the D9 - marriage and the spouse, dharma, and the underlying strength of each planet - and the specific placements in your own chart, such as which planets are vargottama and what sits in the 7th house from the Navamsa Lagna. The navamsa chart's meaning is always read alongside the D1 (Rashi) chart, never on its own.

How is the navamsa sign calculated?

The starting sign of the nine navamsas depends on the nature of the sign the planet sits in: movable (cardinal) signs start their navamsa count from the same sign; fixed signs start from the 9th sign from it; dual (mutable) signs start from the 5th sign from it. Within the sign, the planet falls into one of the nine 3-degree-20-minute parts, and counting forward from that starting sign gives the navamsa sign. This calculator uses the same sidereal Lahiri ayanamsa as our Kundli engine.

What is the Navamsa Lagna and why is birth time so important here?

The Navamsa Lagna is the navamsa sign of your Ascendant (Lagna). Because the Ascendant moves through the zodiac much faster than the planets, its navamsa changes roughly every 13 to 14 minutes of birth time on average (it varies by rising sign and latitude). That is far quicker than the main D1 Lagna, which changes about every two hours. This tool computes how many minutes your entered birth time sits from the nearest Navamsa Lagna boundary, so you can judge how confident to be in your D9 house framework.

What is vargottama and is it rare?

A planet is vargottama when it occupies the same sign in both the D1 and the D9 chart. It is traditionally read as a sign of steadiness or reinforced strength for that planet. It is meaningful but not rare: a planet returns to its own sign in the navamsa for 3 degrees 20 minutes out of every 30-degree sign, so about 1 in 9 placements is vargottama by the math. The tool flags vargottama planets automatically and states this base rate so a flag is not over-read.

What does the navamsa chart say about marriage and the 7th house?

The Navamsa is classically the chart of marriage and the spouse, read together with the D1. Practitioners look at the Navamsa Lagna, the 7th house from it, and the placement of Venus and Jupiter in the D9. This calculator surfaces those positions descriptively as a cultural reference; it does not predict marriage events or outcomes, and any reading should be confirmed with a qualified astrologer.

Navamsa vs Rashi - which matters more?

They are read together, not against each other. The Rashi (D1) is the primary chart of the whole life; the Navamsa (D9) refines it, adding detail on marriage, dharma, and planetary strength. A common maxim is that the D9 refines the D1, it does not override it. A planet that looks strong in the D1 but weak in the D9, or vice versa, is read with that nuance.

How accurate is this navamsa calculator?

It uses Meeus-based VSOP87 planetary theory with the sidereal Lahiri ayanamsa and whole-sign houses, the same engine as our Kundli generator. Planetary and Lagna positions are typically within about 0.3 degrees of observatory-grade ephemerides for dates from 1900 onwards. Because the navamsa divides each sign into nine narrow 3-degree-20-minute parts, a planet sitting within roughly 0.3 degrees of a navamsa boundary can differ from another ephemeris; the tool flags rows near a boundary.

Do I need an exact birth time for the D9 chart?

Yes, more than for almost any other chart. Because the Navamsa Lagna changes about every 13 to 14 minutes, an approximate birth time can place your Navamsa Lagna and its house framework in the wrong sign. If you are unsure of your birth time, treat the result as provisional and use the minutes-to-boundary figure the tool reports as a confidence guide.

Is Navamsa the same as Navmansh, Navamsam, or Navamsa Chakram?

Yes. These are the same chart in different Indian languages. Navmansh Kundli is the common Hindi term, Navamsam or Navamsa Kattam is Tamil, and Navamsa Chakram is Telugu. All refer to the ninth divisional chart described above.
