The short answer
What is Chaldean numerology?
Chaldean numerology is a system that turns the letters of your name into numbers from 1 to 8, then adds them up. You get two results: the full total, called the compound number (like 23), and the single digit it reduces to, called the root (like 5). Many practitioners read the compound first for its extra nuance. Try it with your current name, birth name, or nickname.

Calculate your Chaldean name number
Type one version of a name. We skip spaces and punctuation, read accented letters as their plain versions, and show every letter’s value. (The common Chaldean chart has no letter worth 9.)
The letter chart
The Chaldean numerology chart
Each letter has a value from 1 to 8. Nine doesn’t appear as a letter value in the common modern chart, so a 9 can only show up when you add the letters together.
You can calculate any version of your name: your current name, birth name, nickname, or a creative name. Many practitioners start with the name you use most, since it’s the one you hear every day; others begin with the birth name or compare both. Whichever you pick, note which name you used so you can compare later.
| Value | Letters |
|---|---|
| 1 | A I J Q Y |
| 2 | B K R |
| 3 | C G L S |
| 4 | D M T |
| 5 | E H N X |
| 6 | U V W |
| 7 | O Z |

Two Western name systems
Chaldean versus Pythagorean numerology
Pythagorean numerology runs through the alphabet in order, A = 1 to I = 9, then starts over at J. The Chaldean chart groups letters by a different, older association and leaves 9 out.
If the two systems give you different numbers, neither one is wrong. They count differently, so note which you used.
| Feature | Chaldean | Pythagorean |
|---|---|---|
| Letter values | Grouped 1–8 chart | Alphabet cycles 1–9 |
| Full total (compound) | Often read first | May be shown; the single digit usually leads |
| Which name | Usually the name you use most | Birth and current names are often compared |
| What gets read | Compound, then root | Root first, compound sometimes |
Why the full total matters
Why the compound number comes before the root
The compound number is your total before it’s reduced to one digit. To see what it adds, compare two made-up names using the chart above. Maya Reed adds up to 23 and Evan Ross to 32. Both reduce to 5, but Cheiro’s Book of Numbers gives 23 and 32 their own entries in chapter XIII.
Cheiro calls 23 “the Royal Star of the Lion” and reads it as a fortunate number with help from influential people. He reads 32 favorably too, with an emphasis on working with others while keeping your own judgment. Those are Cheiro’s predictions. We borrowed his themes for the questions below and left the promises out.
| Name and arithmetic | Root | Cheiro’s reading and a question to ask |
|---|---|---|
| Maya Reed: M4+A1+Y1+A1+R2+E5+E5+D4=23 | 2+3=5 | 23 in Cheiro: help from others. Ask: which mentor, introduction, or support could I welcome as I choose a new direction? |
| Evan Ross: E5+V6+A1+N5+R2+O7+S3+S3=32 | 3+2=5 | 32 in Cheiro: working with others while keeping your own judgment. Ask: where can I collaborate without handing someone else my decision? |
A name is lived, not solved
Turn your number into a question
Notice how it feels to hear your legal name, a nickname, a family name, or a creative name. Who says it? What history does it carry? Which role or relationship comes alive? The number can sit alongside that story. It doesn’t replace it.
Changing the spelling changes the math. Make legal or professional name decisions for real-world reasons.
- Choose one version of your name and note why it matters.
- Calculate it and look at every letter value.
- Read the compound and the root as prompts.
- Compare them with your real life.
- Keep what opens a good question and let the rest go.

Questions people ask
Where did Chaldean numerology come from?
It’s named after ancient Chaldea in Mesopotamia, though its real history is long and disputed. The chart most people use today traces back to Cheiro’s 1926 Book of Numbers, and no one can show it came down unchanged from ancient Chaldea.
Is Chaldean numerology accurate?
It’s a spiritual tradition rather than a science, so “accurate” really means “does this reading ring true?” Many people try both Chaldean and Pythagorean numerology and keep the one that feels more like them.
Can Chaldean numerology calculate non-Latin names?
This calculator uses Latin letters. Transliterating a name means making spelling choices that can change the result, so someone who knows the original language and naming tradition is your best guide.
Will changing the spelling of my name change my life?
It changes the number. There’s no evidence that spelling alone changes your destiny, but a name that feels more like you can still matter.
