How to use this calculator
- Type a Greek word, such as λόγος, and its isopsephy value appears at once.
- Tap any method to feature it, with each letter's value shown below.
- Type in English instead and it switches to the standard English ciphers.
Accents and breathing marks are ignored, so you can type λόγος or λογος and get the same total.
What is Greek gematria?
Greek gematria, known by its own name isopsephy, is the practice of adding up the number values of Greek letters. The Greek alphabet was used for counting long before separate numerals, so alpha is 1, beta is 2, on up to omega at 800. Add the letters of a word and you get its number.
The best-known example is Ἰησοῦς, the Greek for Jesus, which comes to 888. Early Christian writers read that number as a deliberate counterweight to the 666 of Revelation. For the wider story across languages, see our guide to gematria.
Understanding the calculations
The large number is the total for the highlighted method. Under it, every letter shows the value that method gives it, and those values add up to the total. For example, in Isopsephy the word λόγος works out as λ 30 + ο 70 + γ 3 + ο 70 + ς 200 = 373. If you type more than one word, the line below shows what each word comes to on its own.
Each method assigns numbers to letters in its own way, so the same word lands on a different total in each one. Switch λόγος to Ordinal and it becomes 62 instead. Tap any method in the grid to feature it. None of them is the one right answer; you use whichever your tradition or method calls for. To read where these methods come from and which are old or modern, see the guide to the gematria ciphers.
Tap the large total to open its number properties: whether the number is prime, what it factors into, which sequences it belongs to, and how it reads in binary, hexadecimal and other bases. The same panel sits on the Numbers page, where you can look up any number on its own.
If your text includes digits, like a year or an age, the Numbers buttons set how they are counted. Take the number 2024:
- Smart keeps a short number whole (so 11 stays 11) but splits a long one into single digits, so 2024 becomes 2 + 0 + 2 + 4 = 8.
- Full always uses the whole number, so 2024 stays 2024.
- Reduced adds up the digits, so 2024 becomes 8.
- Off leaves numbers out of the total, the same as not typing them.

Frequently asked questions
What is Greek gematria?
Greek gematria is the practice of giving each Greek letter a number and adding them up for a word. Its traditional name is isopsephy, which means "equal in number."
What is isopsephy?
Isopsephy is the Greek word for gematria. It comes from isos (equal) and psephos (pebble, once used for counting), and it describes finding the number value of a Greek word.
How do you calculate Greek gematria?
Give each letter its standard value, then add those values across the whole word. Alpha is 1, iota is 10, rho is 100, on up to omega at 800.
What is the number 888 in Greek gematria?
888 is the value of Ἰησοῦς, the Greek spelling of Jesus. Early Christians pointed to it as a counterpart to the 666 of the Book of Revelation.
What happens when I tap the total?
Tapping the large number opens its properties, such as whether it is prime, how it factors, and how it reads in other bases. So 888, the value of Ἰησοῦς, opens its full breakdown. You can also look up any number on the Numbers page.
