In India, name numerology is everywhere. Parents check baby names, shop owners choose business names, and buyers pick a "lucky" vehicle or flat number. Most of these calculations use the Chaldean system. This guide explains exactly how it works: the letter chart, how compound and root numbers are calculated, how it differs from the other popular system, and how to read the results from our free Chaldean Name Numerology Calculator.

Numerology is a traditional belief system, not a science, and we explain what the evidence says near the end. If you are curious about the method behind the numbers, read on.

Using the calculator in 10 seconds

  1. Open the Numerology Calculator.
  2. Type a name, business name or vehicle number. Results update as you type.
  3. Read the compound number (the total) and the single root number (the total reduced to one digit), plus the letter-by-letter breakdown.

Everything is calculated in your browser, and nothing you type is sent to our server.

1. What is name numerology?

Name numerology gives every letter a number, adds up the numbers in a name, and interprets the result. Supporters believe a name's number reflects the personality or "vibration" associated with it. The two systems used most today are the Chaldean system, the most common in India, and the Pythagorean system, more common in Western books and apps.

Despite the ancient-sounding names, both systems as we know them were largely shaped in the early 20th century. The Chaldean method was popularised by the palmist and astrologer known as Cheiro (William John Warner), who named it after the Chaldeans of ancient Babylon. The modern Pythagorean method was popularised by Mrs L. Dow Balliett and later writers. Historians find no evidence that Pythagoras himself used this kind of letter-number system.

2. The Chaldean letter chart

In the Chaldean system, letters are grouped by their sound rather than their order in the alphabet, and only the numbers 1 to 8 are used. The number 9 is considered sacred and is not given to any letter, although 9 can still appear as a total.

Number Letters
1A, I, J, Q, Y
2B, K, R
3C, G, L, S
4D, M, T
5E, H, N, X
6U, V, W
7O, Z
8F, P

This is the chart our calculator uses. Upper and lower case are treated the same, and spaces, dots and other symbols are ignored.

3. Chaldean vs Pythagorean numerology

The Pythagorean system is simpler: it numbers the alphabet in order from 1 to 9 and then starts again (A=1 … I=9, J=1 … R=9, S=1 … Z=8).

Because the charts differ, the same name usually gives different numbers in the two systems. For example, "PRIYA SHARMA" adds up to 29 (root 2) in the Chaldean system, but to 57 (root 3) in the Pythagorean system. That is the most common reason two numerology websites give you different answers.

4. How the calculation works

Take the example name PRIYA SHARMA:

  1. Convert each letter using the Chaldean chart:
    P=8, R=2, I=1, Y=1, A=1, S=3, H=5, A=1, R=2, M=4, A=1
  2. Add them all up: 8 + 2 + 1 + 1 + 1 + 3 + 5 + 1 + 2 + 4 + 1 = 29. This is the compound number.
  3. Reduce to a single digit by adding the digits until one digit remains: 2 + 9 = 11, then 1 + 1 = 2. This is the root number.

Our calculator does exactly this and shows each step, for example "P=8 + R=2 + I=1 …", so you can check the result.

5. Compound numbers and root numbers

Some practitioners pay more attention to the root number, others to the compound number. Our calculator shows both.

6. Business names and vehicle numbers

Many people want the number of a business name, a vehicle registration or a house number, and these often contain digits. Some calculators simply ignore digits. Ours adds each digit at its face value, from 0 to 9, so mixed letters and numbers are fully counted.

Business name example: "SUNRISE BAKERY"
S=3, U=6, N=5, R=2, I=1, S=3, E=5, B=2, A=1, K=2, E=5, R=2, Y=1. The compound number is 38 (3 + 8 = 11, 1 + 1 = 2), so the root number is 2.

Vehicle number example: "KA01AB1234"
K=2, A=1, 0, 1, A=1, B=2, 1, 2, 3, 4. The compound number is 17 (1 + 7), so the root number is 8.

Practitioners differ on whether to count the state code or the dashes and spaces in a registration number. Dashes and spaces are ignored by our calculator; type only the parts you want to count.

7. Traditional meanings of root numbers

In Indian numerology, each root number is associated with a planet, and with personality traits drawn from popular numerology books. They are listed here for interest, as tradition holds them, not as predictions.

Root Planet Traits commonly associated
1SunLeadership, independence, ambition
2MoonSensitivity, cooperation, imagination
3JupiterCreativity, expression, optimism
4RahuDiscipline, practicality, unconventional thinking
5MercuryCommunication, adaptability, love of change
6VenusHarmony, family, beauty and comfort
7KetuIntrospection, spirituality, analysis
8SaturnHard work, patience, responsibility
9MarsEnergy, courage, compassion

Western writers following Cheiro often link 4 with Uranus and 7 with Neptune instead of Rahu and Ketu.

8. A balanced view

Numerology is a traditional belief system, not a science. Controlled tests of numerology predictions have not found them to be more accurate than chance, and different systems give different numbers for the same name, which is hard to reconcile with either being "correct". Many people enjoy numerology as a cultural tradition or for curiosity, and that is how we suggest using it:

Frequently asked questions

Why is the number 9 not in the Chaldean chart?

In the Chaldean tradition, 9 is treated as a sacred number, so no letter is given the value 9. A total can still add up to 9, and digits typed as 9 are counted.

Should I use my full name or the name I'm called?

Practitioners differ. Many Chaldean numerologists use the name you are most commonly known by, since that is the one used every day. You can try both in the calculator and compare.

Why does another numerology website give a different number?

It may use the Pythagorean chart, ignore digits, or treat initials differently. Our calculator uses the Chaldean chart above and counts digits at face value.

Is my name stored anywhere when I use the calculator?

No. The calculation runs entirely in your browser, and nothing you type is sent to our server. See our privacy policy.

Worked examples were calculated with the same method as our calculator. Historical notes and the summary of evidence are drawn from published histories of numerology and skeptical reviews of its claims. This article is for general interest only.
