A simple comparison of Chaldean and Pythagorean numerology, including letter chart differences, calculation style, and a worked example.
Chaldean and Pythagorean numerology are different name-number systems. The biggest difference is the letter chart. This site uses the Chaldean chart, where letters are assigned values from 1 to 8 and 9 is not assigned to letters. Pythagorean numerology uses a different 1 to 9 letter pattern.
| Topic | Chaldean numerology on this site | Pythagorean numerology |
| --- | --- | --- |
| Letter values | Uses a 1 to 8 chart | Uses a 1 to 9 chart |
| Number 9 in the chart | Not assigned to letters | Assigned in the letter cycle |
| Main use here | Name, word, and brand calculations | Not used by this calculator |
| Result style | Compound total plus reduced number | Usually reduced number focused |
| 11 and 22 | Preserved when they appear as reduced numbers | Rules vary by source |
The letter chart controls the whole result. If two systems assign different values to the same letters, the final number can change.
That is why you should not mix charts in one calculation. If you start with the Chaldean chart, keep using the Chaldean chart for the whole name.
You can check the exact values used by this site on the Chaldean letter values page.
Take the name Maya.
In the Chaldean chart used here:
The total is 7, so the compound number is 7 and the simple number is 7.
In another system, the letter values may be different. That would produce a different result. The difference is not a bug. It means the systems are using different rules.
Use one system consistently. If you are using this website, use the Chaldean method described in the methodology page.
The useful question is not which system is universally correct. The useful question is whether you understand the method being used and apply it consistently.
If you want a Chaldean result, use the Chaldean name number calculator. It applies the same letter map, reduction method, and 11/22 rule each time.
If you want to inspect why a result appears, compare the name against the Chaldean chart and read the calculation methodology.
This site does not claim one system is scientifically better. They are different symbolic systems with different letter maps.
It may be using a different chart, a different reduction rule, or a different way of handling spaces and punctuation.
No. This site is focused on Chaldean numerology.
You can compare them as symbolic interpretations, but do not mix their letter values inside one calculation.
Use numerology as a reflection tool. Do not treat any system as scientific proof, professional advice, or a guaranteed outcome.
