A simple explanation of why the Chaldean letter chart uses values 1 to 8, why 9 is not assigned to letters, and how 9 can still appear in name results.
Chaldean numerology does not assign the number 9 to letters in the standard letter chart used by this calculator. Letters are mapped from 1 to 8. The number 9 is still meaningful, and it can still appear as a compound or reduced result, but it is not used as a letter value in the chart.
The Chaldean chart gives each letter a number value. For example, A has a value of 1, B has a value of 2, and C has a value of 3 in the chart used by this site.
You can see the full map on the Chaldean letter values chart. That page shows every letter group from 1 to 8.
In this Chaldean-style letter chart, 9 is traditionally treated differently from the other values. It is not placed under a letter group.
That does not mean 9 is bad. It also does not mean a name should avoid 9. It simply means the letter-to-number map does not use 9 as a direct letter value.
Even though no letter has a value of 9, a name can still produce 9 after adding the letter values.
For example, if a name totals 18, the compound number is 18. Then 1 + 8 = 9, so the simple number is 9.
The result can also be a single-digit 9 if the letter values add to 9 directly. The chart does not assign 9 to a letter, but the calculation can still reach 9 through addition.
Imagine a name where the letter values add to 27.
That result is still valid in this calculator. The rule only says that no individual letter starts with the value 9.
If you are checking a name, use the Chaldean name number calculator and read the result it gives you. You do not need to manually place any letter under 9.

No. The chart does not assign 9 to letters, but 9 can still appear as a name total or reduced number.
Yes. A name can reduce to 9 even though no single letter has the value 9.
No. This site does not treat 9 as something to fear or avoid. It should be read symbolically and responsibly.
No. Pythagorean numerology uses a different letter-value chart. This site uses the Chaldean chart shown on the letter values page.
Use this rule as part of the calculation method. Do not treat the absence of 9 in the letter chart as a warning, promise, or prediction.
