Word Value Formula
The calculator converts each letter to a number using the chosen scheme, then combines those numbers based on the selected output.
Sum = v(L1) + v(L2) + ... + v(Ln)
Product = v(L1) * v(L2) * ... * v(Ln)
DigitalRoot(N) = 1 + ((N - 1) mod 9), for N > 0
- v(L) = numeric value assigned to letter L by the chosen method
- L1…Ln = each countable letter or digit in the input
- N = the raw sum to reduce
- DigitalRoot(0) = 0
Assumptions: letters are case insensitive, accents are stripped (café becomes cafe), and non-letter characters other than digits are skipped. Digits are only counted if you set the numbers option to add them. The Pythagorean and Chaldean systems compress letters into 1 to 9 ranges, so their digital roots tend to be smaller than A1Z26 results.
Calculator modes:
- Calculate Value applies the sum, digital root, or product formula above to your text. The “Show each word separately” option runs the same formula on each word and lists the results in a table.
- Target Value reverses the process. It enumerates every 1, 2, or 3 letter combination and returns those whose sum or digital root matches your target.
- Numbers in text controls whether digits are added one by one (5 in “25” contributes 2 + 5) or as whole numbers (25 contributes 25).

Common reference totals to sanity check your output:
| Word | A1Z26 sum | Digital root | Scrabble sum |
|---|---|---|---|
| CAT | 24 | 6 | 5 |
| LOVE | 54 | 9 | 7 |
| HELLO | 52 | 7 | 8 |
| QUIZ | 60 | 6 | 22 |

Worked Examples and FAQ
Example 1: A1Z26 sum of CODE. C=3, O=15, D=4, E=5. Sum = 3 + 15 + 4 + 5 = 27. Digital root = 2 + 7 = 9.
Example 2: Pythagorean reduction of NAME. N=5, A=1, M=4, E=5. Sum = 15. Digital root = 6.
Example 3: Scrabble score of QUIZ. Q=10, U=1, I=1, Z=10. Sum = 22. This matches the raw tile score before any board bonuses.
Example 4: Target search. Set target 30, A1Z26, exact sum, length 2. Matches include DZ (4+26), EY (5+25), FX (6+24), and so on through every pair that adds to 30.
Why does my digital root differ between methods? Each method assigns different numbers to the same letter. A1Z26 sum for HELLO is 52 (root 7), while Pythagorean is 25 (root 7 as well in this case, but the raw sums differ). Compare totals using the same method.
What happens to spaces, punctuation, and accents? Spaces and punctuation are ignored. Accents are stripped before counting, so É is treated as E.
Should I add digits or whole numbers? Use “Add each digit” when you want a numerology style reduction of a date or ID. Use “Add whole numbers” when a number in the text should keep its full value, like a street address.
Why is the product so large? Product multiplies every letter value, so even short words can produce big numbers. A 6 letter word using A1Z26 can easily exceed one million.
How is Chaldean different from Pythagorean? Both compress letters into single digits, but Chaldean skips the number 9 in its letter assignments and groups letters by sound rather than alphabet position.
