Chaldean Numerology: Letter Chart, Compound Numbers and History

Chaldean numerology values letters from 1 to 8 by their sound and pays attention to compound numbers. Here is the chart, a worked example, and what is known about where it comes from.

Quick answer: what is Chaldean numerology?

Chaldean numerology gives each letter a value from 1 to 8 based on its sound rather than its place in the alphabet; 9 is not given to any letter. You add the letters of the name you use every day, read the unreduced "compound" total (such as 39) and then reduce it to a single digit.

No letter has the value 9. In the tradition, 9 is treated as special and is left out of the letter table, although a total can still reduce to 9.

Chaldean calculation

  • M(4) + A(1) + R(2) + I(1) + A(1) = 9
  • L(3) + O(7) + P(8) + E(5) + Z(7) = 30
  • Compound total: 39 → 3 + 9 = 12 → 1 + 2 = 3

Compound 39, single number 3

The same name gives 8 in the Pythagorean system. That difference is normal; see Pythagorean vs Chaldean.

Compound numbers

Chaldean readings give weight to the two-digit total before it is reduced. Cheiro’s 1926 book lists meanings for compound numbers from 10 to 52, and many modern practitioners follow his list. The single digit is read as the core meaning and the compound as extra detail.

Chaldean numerology traditionally uses the name you are known by now, not necessarily your birth name, which is why it is popular for name changes and business names.

Is Chaldean numerology really from ancient Babylon?

The Chaldeans were a people of southern Babylonia, famous in the ancient world for astronomy and astrology. The numerology named after them, though, has no known Babylonian source: Babylonian texts did not use the Latin alphabet, and historians have not found the letter table in any ancient record.

The system as it is used today became popular in the 1920s through the palmist Cheiro (William John Warner). See our methodology page for sources.

Frequently asked questions

Why is there no 9 in Chaldean numerology?

Tradition holds that 9 is a sacred or complete number, so it is not assigned to any letter. A name’s total can still reduce to 9.

Should I use my birth name or my current name?

Chaldean practitioners usually use the name you go by now, because they focus on how a name sounds when it is used.

Does Chaldean numerology use master numbers?

Usually not. It relies on compound numbers instead. AngelSign’s Chaldean calculator reduces all the way to a single digit and shows the compound number alongside it.
