Chaldean Numerology Calculator

Chaldean letter system (values 1–8)

In Chaldean tradition, calculating the common or most frequently used name (rather than birth certificate name) is often emphasized.

Letters are valued 1 to 8; no letter is given 9.

Official Chaldean Letter-Value Table (1–8)

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

* The number 9 does not appear in the table. Chaldean tradition treats 9 as special, so no letter is given that value.

Chaldean result

Compound 66 / Root 3

The Communicator • 3 is the number of self-expression. It stands for creativity, communication and optimism. People with a strong 3 are usually sociable, talkative and drawn to writing, art, performing or anything that lets them share ideas.

Letter-by-letter working:A(1) + R(2) + T(4) + H(5) + U(6) + R(2) + P(8) + E(5) + N(5) + D(4) + E(5) + L(3) + T(4) + O(7) + N(5) = 66 → 6 + 6 = 12 → 1 + 2 = 3 = 3

How Chaldean Numerology Differs From Pythagorean

1. Sound vs. alphabetical order: Pythagorean numerology assigns numbers sequentially (A=1, B=2, C=3... I=9). Chaldean numerology groups letters by sound, so letters that sound alike share a value. The table is credited to ancient Babylon by tradition but is documented only from the early 20th century.

2. The Absence of Number 9: Pythagorean uses 9 for I and R. Chaldean gives no letter the value 9, although a total can still reduce to 9.

3. Everyday Name Emphasis: While Pythagorean focuses on the birth certificate name, Chaldean emphasizes the name you are known by daily.

When to use this calculator

Use this calculator when you want a name reading with the Chaldean system, which many practitioners use for names and business titles. It gives a compound number (such as 39) and a single digit, and shows the working.

How it is calculated

  1. Convert each letter with the Chaldean table (values 1 to 8; the number 9 is not assigned to a letter).
  2. Add the values to get the compound number.
  3. Reduce the compound number step by step to a single digit.
  4. Read both the compound and the single digit.

Worked example

Input: Maria Lopez

Working: M4 + A1 + R2 + I1 + A1 + L3 + O7 + P8 + E5 + Z7 = 39. Then 3 + 9 = 12, and 1 + 2 = 3.

Result: Compound 39, single digit 3

Common mistakes

  • Using the Pythagorean table and expecting a Chaldean result.
  • Looking for a letter worth 9: the Chaldean table has none.
  • Ignoring the compound number; Chaldean readings treat it as meaningful on its own.

Frequently asked questions

Which system should I use for a name?
