What Is Gematria?
Gematria gives every letter a number and adds them up. The total depends on two things: the exact spelling and the table you use.

Gematria assigns values to letters and adds them for a written word. Gematria is used in Jewish textual interpretation with Hebrew letter values. Greek letter-sum calculation is called isopsephy; Hebrew and Greek letters also served as numerals. Modern English tables are conventions. A Latin table labeled Jewish is distinct from the historical Hebrew script and does not translate English into Hebrew. This calculator provides reproducible totals and comparisons, while leaving interpretation to you and your tradition.

Gematria in Biblical Study
The Jewish Encyclopedia documents gematria in Jewish textual interpretation. The USCCB notes on Revelation 13:18 discuss a name calculated from numerical letter values. When studying a passage, record the edition, original spelling, letter table and source commentary. Use the Hebrew Gematria Calculator or Greek Gematria Calculator for native text. Interpretation remains with you and your tradition; this calculator does not translate biblical text.
Reproduce a source example
Nedarim 32a:17 discusses an interpretation involving Eliezer and the number 318. To reproduce the letter total here, use the Hebrew spelling אליעזר with Hebrew Standard.
Hebrew Standard (Mispar Hechrachi) · אליעזר
Total: 318
Recalculate אליעזר — Hebrew Standard (Mispar Hechrachi)The source displays the pointed spelling אֱלִיעֶזֶר. This calculator ignores those vowel points when adding the base letters, so that spelling also gives 318. The arithmetic can be checked separately from the interpretation discussed in the text.
Hebrew Standard (Mispar Hechrachi) · אֱלִיעֶזֶר
Total: 318
Recalculate אֱלִיעֶזֶר — Hebrew Standard (Mispar Hechrachi)Changing the input or table changes the question. Neither of these comparisons is the Hebrew Standard calculation above.
Hebrew Ordinal (Mispar Siduri) · אליעזר
Total: 66
Recalculate אליעזר — Hebrew Ordinal (Mispar Siduri)To record a reproducible result, keep four things together: the source reference, exact spelling, method name and letter breakdown. A match in a limited word list does not establish the interpretation of a text.
Source passage: Nedarim 32a:17 on Sefaria (paragraph 17).

Keep a complete result record
Text: listen
Script: Latin A–Z · Method: English Ordinal
Counted letters: listen
Breakdown: 12 + 9 + 19 + 20 + 5 + 14 = 79
Total: 79. Recalculate listen in English Ordinal
Text: silent
Script: Latin A–Z · Method: English Ordinal
Counted letters: silent
Breakdown: 19 + 9 + 12 + 5 + 14 + 20 = 79
Total: 79. Recalculate silent in English Ordinal
“79 means listen” is not a complete record: silent also totals 79 in English Ordinal. A number alone cannot uniquely identify a word or automatically establish its meaning. Keep text, script, method, breakdown and total together so someone else can repeat the calculation.
These words share a total in the selected table. The spelling and letter values are shown so you can examine the result in your own context.
Gematria is used in several traditions of textual study and numerical interpretation, each with its own sources, methods, and conventions. Gematria.tools provides letter values, reproducible totals, and comparisons for the spelling and method you select. We welcome Jewish textual study, Christian biblical study, numerology, and other forms of exploration, while leaving interpretation to you and the tradition or context you bring to your work. We do not offer religious rulings or personalized predictions. When recording or sharing a result, include the original text, the selected method, and any relevant source or context.
How to Use Gematria
Spelling decides the total
Capital letters do not change it. Spaces, digits and punctuation add nothing.
Translation is not automatic
An English spelling of a Hebrew name is not Hebrew. Type the script you want to study.
Name your table
Share the spelling and table so another person can check your number.
Check it by hand
Open the letter breakdown and add the values yourself. Each total can be repeated.

Choose the script and method
Hebrew Mispar Hechrachi uses units, tens and hundreds; final forms keep their ordinary values. The Mispar Gadol option here assigns 500–900 to the five final forms. Hebrew Ordinal (Mispar Siduri) uses positions 1–22, with final forms retaining their ordinary positions. Greek isopsephy accepts final sigma and historical numeral signs. Use native letters for these methods. English transliterations are different inputs and are not converted automatically.
English Ordinal and Simple English both use A–Z positions. Reverse Ordinal counts backward. Full Reduction reduces each letter’s assignment before addition; Reverse Full Reduction applies this to reversed assignments. The final sum is not reduced again. English Sumerian is a modern calculator label for English Ordinal multiplied by six; it does not transliterate Sumerian text. The Jewish Latin mapping has its own values. Compare visible assignments when websites use different names for their tables.
Calculate and check
Type a word, name or phrase, select a result row, and inspect the letter breakdown. Count every repeated letter. Names use the same rule as ordinary words. Case does not affect a result. Spaces, punctuation and digits do not count. Latin tables skip accented letters outside A–Z; Greek combining marks and Hebrew vowel points are ignored for calculation and preserved in the original text while supported base letters count. Each table evaluates only its own script in mixed text.
To count a number’s written form, type its words. To find words with a specific total, use Decoder. Record the exact spelling and table name with a result. Shared calculator links restore that spelling. Check the individual letters when another tool gives a different sum: spelling, final forms and character handling can explain the disagreement.
Matching sums and privacy
Under a fixed letter table, anagrams share a total because the same letter values are added. Other entries can also share totals, including across several tables. Record the exact spelling, methods, and sources when studying these matches; interpretation remains with you and your tradition.
Concordance searches a limited independent list of licensed words, names and original phrases, with a frequency-ranked Hebrew list and original Greek entries. Hebrew results follow source frequency; English results sort by SCOWL commonness tier, shorter entries, then alphabetically. An empty list does not prove that a total is unique. Free results show five entries. Pro adds full matching lists, intersections, cloud history and favorites, custom tables and batch CSV; standard calculations remain free.
Letter totals are calculated in your browser. Anonymous recent words remain on this device. Concordance sends the chosen totals and current text to exclude it from matches. Signed-in Pro accounts can store private notebook entries in the cloud. Avoid private text in shared URLs.
