How to use Calculate Letter Sum
- 1. Paste your text. Enter a word, name or phrase into the input pane. Each letter is mapped to its position in the alphabet, so a equals 1, b equals 2, up through z equals 26.
- 2. Choose whether to sum per word. Turn on Sum each word separately to get one total per word instead of a single grand total. Leave it off when you want one combined number for the whole input.
- 3. Read the total. The output shows the letter-value sum, or a list of per-word sums if you enabled that option. Non-letter characters like spaces and punctuation are ignored in the count.
When to use Calculate Letter Sum
Calculate Letter Sum adds up the alphabet position of every letter in your text using the classic a1z26 scheme. It is the tool to reach for when you need a numeric fingerprint of a word based on its letters rather than its ASCII codes.
- Exploring gematria and numerology. You want to compare the letter sums of two names or words as part of a numerology exercise or word puzzle. Paste each one in and compare the resulting totals.
- Building a simple checksum puzzle. An escape-room or puzzle-hunt clue asks solvers to add up the a1z26 values of a phrase to reveal a number that unlocks the next step. Verify the intended answer here.
- Comparing per-word totals in a phrase. You want to see which word in a sentence carries the highest letter-sum value, useful for word games that rank entries by their numeric weight. Enable per-word sums to see each one.

About the Calculate Letter Sum tool
Calculate Letter Sum runs as plain JavaScript in your browser tab, with no server behind it. Add up letters as numbers, where a = 1, b = 2, … z = 26. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Text Tools section, 211 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with the Sum each word separately setting, and the result refreshes the moment you change it. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
