A simple beginner guide to Chaldean numerology, letter values, compound numbers, simple numbers, and responsible use.
Chaldean numerology is a traditional name-number system. It gives each letter a number value, adds those values together, and reads both the full compound number and the reduced simple number. On this site, it is used as a symbolic reflection tool, not as science or a guaranteed prediction.
The method starts with the Chaldean letter chart. Each letter from A to Z 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 by this calculator.
When you enter a name, the calculator adds the letter values. That full total is the compound number. Then it reduces the total by adding the digits together until a simple number is reached. If the reduced number is 11 or 22, this calculator keeps it as a master number instead of reducing it again.
You can check the full chart on the Chaldean letter values page. That page shows which letters belong to each number and lets you test a name while viewing the chart.
For a simple example, take the name Maya. In the Chaldean chart, M is 4, A is 1, Y is 1, and A is 1. The total is 7. The compound number is 7, and the simple number is also 7 because no further reduction is needed.
For a longer name, the total may be two digits. If a name totals 23, the compound number is 23. Because 2 + 3 = 5, the simple number is 5. Both numbers matter because 23 and 5 are not read in exactly the same way.
Start with the Chaldean name number calculator. Enter a name, read the compound and simple number, then compare the result with the number meanings guide.

No. Chaldean numerology uses a specific letter-value chart. Other systems may use different letter values and different reduction rules.
No. It is a symbolic and traditional interpretation system. It should not be treated as scientific proof or professional advice.
Use the name you want to understand. A full legal name, first name, brand name, pen name, or business name can all be checked, but they answer slightly different questions.
Use Chaldean numerology as a reflection tool. Do not use it as the only reason for important personal, legal, medical, financial, or relationship decisions.
