Value Calculator
Enter Arabic text, choose a calculation system, then run the count. Each letter's value is drawn from the classical letter-number (Abjad) sequence.
How the count works
Every Arabic letter has always doubled as a number. The order isn't alphabetical — it follows an old mnemonic sequence (أبجد هوز حطي كلمن سعفص قرشت ثخذ ضظغ) that assigns 1 through 10, then the tens, then the hundreds, up to 1000 for the final letter. Nisāb reads your text letter by letter, looks up each one against the sequence you've chosen, and adds them together.
Choosing a system
- Eastern (Mashriqi): the order most commonly taught and used across the Arab East.
- Western (Maghribi): reassigns six of the later letters, a variant historically used in North Africa.
- Sequential: a modern convenience system — letters simply numbered 1–28 in dictionary order.
Compare Names
Calculate up to four names side by side using the system selected in the calculator tab.
Compatibility Check
A simple, transparent scoring method: the closer two totals are relative to their size, the higher the score. This is a numeric comparison, not a prediction.
Reverse Lookup
Enter a number to find which letter carries that exact value, plus a few two-letter combinations that add up to it.
Baby Name Selector — Ilm‑ul‑Adad (the Science of Numbers)
Combines the mother's name with the child's date, time, and place of birth into one number, reduces it to a single-digit "reduced number" (Mufrad) using the classical smaller-form (Abjad Saghir) reduction, then lists the letters that share that digit as recommended starting letters — the same mechanism used in printed Ilm‑ul‑Adad (numerology) naming charts. This covers the numerology side only; it doesn't calculate a birth chart, ascendant, or planetary rulership, which need dedicated astrological software and a verified birth location.
The Ascendant is computed from real spherical-astronomy formulas — Julian Day, Greenwich Sidereal Time, and the obliquity of the ecliptic — using the birth time, latitude, longitude, and UTC offset you provide. It uses the tropical zodiac and, unlike commercial ephemeris software, does not correct historical timezone/DST rules for you, so its accuracy depends entirely on the UTC offset you enter. Treat it as a solid approximation rather than a certified chart.

Shortlist
checking sync…Zikr (Remembrance) Counter with Letter-Value (Abjad) Tracker
Enter a phrase of remembrance, then tap to count repetitions. Nisāb tracks the phrase's letter-number value (Abjad) alongside your running tally, so you can see the cumulative weighted total as you go.
Magic Square & Taweez (Amulet) Decoder
Fill each cell with a number or a single Arabic letter (letters are converted to their letter-number value (Abjad) using the system chosen below). Nisāb totals every row, column, and diagonal and checks whether they match.

Reduced-Number Table (Mufrad / Abjad Saghir)
Each of the 28 standard Arabic letters' value reduced to a single digit (its digital root). This is what the Baby Name Selector uses to match a birth number to candidate starting letters.
About the systems shown here
These tables reflect the letter orderings documented in traditional references on letter-numerals (Abjad). Different regions and schools have used slightly different orderings, most notably the Eastern and Western variants shown above, so a value that looks "correct" in one tradition can differ from another. When in doubt, check which convention your source or teacher follows.
