In Pythagorean Numerology, each letter in your name is given a single digit number, based on the chart below.

Your Personality number is derived from the consonants of your full name at birth.

Pythagorean Numerology Numbers Alphabet Letters Chart
To calculate your Personality number, assign each consonant of your name a number from the chart.

Do this separately for your First Name, Middle Name (if you have one), and Last Name (Surname). For each of your names add the numbers up separately, reducing them down to a single digit value. When you have the numbers for each of your names, add these up and again reduce to a single digit to come up with your Personality Number.

Note: If at any time in your calculations you encounter a master number (11,22, or 33) do not reduce it any further.

  1. Sarah

    My son has been inspired to change his name to take on my (birth) last name, and change his middle name to honour his deceased grandfather. His name is currently Grayson Lewis Bell and he is changing it to Grayson Terence Mann. How will this change affect his destiny number? Will he still retain his original destiny number, but may it perhaps expand to also include the properties of the new destiny number? The name change by the way is divinely inspired. Thank you.

  2. Darlene

    If I was adopted and had a different name do I use my birth name or adopted name? And if adopted name, maiden name or married name?

    • se7en

      Hi Darlene,
      This is somewhat of a grey issue. Most agreement is that you should still use your birth name, unless you were adopted at a very early age.

  3. Aubree

    Hello there, I calculated all my numbers and all but my hearts desire, and expression number seemed accurate...
    I got 8 for expression/destiny, 11 for life path, 3 for hearts desire/soul urge, and 5 for my personality number. I was confused on my 'day' number...I was born March 15th, - I wasn't sure if it would be a 6?
    My name is Aubree Elizabeth Nielsen Wallery. I would greatly appreciate any input! Thank you so much in advance!

    • se7en

      Hi Aubree, you need to provide your full date of birth as well for me to help you with your Life path number. However, i would recommend that instead of posting all your personal information on a public forum, please go to the following page and fill in your information there instead for a free numerology reading. It will give you a much more in-depth analysis of your entire numerological chart -

  4. Jadyn

    My name is
    Jadyn-le Hoang Browne
    Every time I calculate my name numbers I get 11 but the website gets 22 am I just doing it wrong??

    • se7en

      Hi Jadyn, both your expression and your heart's desire numbers are 22. For your personality number ...
      first name = J + D + N + L = 1 + 4 + 5 + 3 = 13 = 4
      middle name = H + N + G = 8 + 5 + 7 = 20 = 2
      last name = B + R + W + N = 2 + 9 + 5 + 5 = 21 = 3

      Your Personality Number = 4 + 2 + 3 = 9
