A simple step-by-step guide to calculating a Chaldean name number using letter values, compound totals, simple reduction, and the 11/22 rule.
To calculate your Chaldean name number, convert each letter in the name into its Chaldean number value, add those values together, then reduce the total. The full total is the compound number. The reduced result is the simple number. This calculator preserves 11 and 22 when they appear as the reduced number.
Start with the name you want to understand. It can be a first name, full name, business name, pen name, or brand name.
This calculator reads letters from A to Z. Spaces, punctuation, and unsupported characters are ignored for the number total, so the important part is the spelling of the letters themselves.
In the Chaldean system used by this site, each letter has a value from 1 to 8. The number 9 is meaningful in numerology, but it is not assigned to letters in the standard Chaldean chart used here.
You can check the full mapping on the Chaldean letter values chart.
The compound number is the full total before reduction. It gives extra context because two names can reduce to the same simple number while having different compound totals.
For example, a name that totals 14 and a name that totals 23 both reduce to 5, but the compound totals are different. That is why the calculator shows both numbers.
The simple number is found by adding the digits of the compound number together. If the total is 23, then 2 + 3 = 5. The simple number is 5.
If the reduced number is 11 or 22, this calculator keeps it as 11 or 22 instead of reducing it again. For example, 29 reduces to 11, and 49 reduces to 22.
Here is a simple example using the name Maya.
Add the values together: 4 + 1 + 1 + 1 = 7.
The compound number is 7. The simple number is also 7 because the total is already a single digit.
If a name totals 23, the compound number is 23. Then you reduce it: 2 + 3 = 5. The simple number is 5.
This is why both numbers matter. The compound number shows the full total, while the simple number shows the reduced tone of the name.
The easiest way to check a name is to use the Chaldean name number calculator. Enter the name, then review both the compound number and the simple number.

A Chaldean name number is the number result found by converting the letters in a name into Chaldean values, adding them together, and reading the compound and reduced numbers.
Use the name you want to check. A first name, full name, public name, business name, or pen name can each be read, but they answer slightly different questions.
This calculator focuses on mapped letters. Spaces, punctuation, and unsupported characters are ignored for the number total.
In the Chaldean chart used here, letters are assigned values from 1 to 8. The number 9 is still meaningful, but it is not used as a letter value in this chart.
No. The result is a symbolic and traditional interpretation. It should not be treated as scientific proof or a guaranteed outcome.
Use a Chaldean name number as a reflection tool. It can help you compare names and spellings, but it should not replace practical judgment, personal preference, or professional advice where that applies.
