How it works

Chaldean letter values, Vedic Mulank and Bhagyank, compatibility from classical planetary friendships. Every step shown.

Numerology has many schools, and they don't always agree. Rather than mix them silently, we have written down exactly which rule we use for each job, and why. The same rules apply to everyone, and every report ends with a maths appendix that shows them applied to your inputs.

The calculators show your Mulank verdict free; the report adds your Bhagyank verdict, score and a shopping list. Every rule behind them is on this page, so you can also work them out by hand.

Which rule we use for what

Step 1: reducing a number

Most of numerology comes down to one move: add the digits, and keep adding until one digit is left. We record every step.

• The first total is the compound number.
• The final single digit is the root number.

Example: 42 → 4 + 2 = 6. Compound 42, root 6.

Master numbers. If a step lands on 11, 22 or 33, we show it as a note, because many numerologists give these numbers special attention. For compatibility and ranking we still use the reduced root.

Example: 29 → 2 + 9 = 11 → 1 + 1 = 2. Compound 29, master number 11 noted, root 2.

Step 2: your Mulank and Bhagyank

Mulank comes from the day you were born.

Born on the 23rd: 2 + 3 = 5. Your Mulank is 5.

Bhagyank comes from your whole date of birth, DD/MM/YYYY.

Born on 23/07/1994: 2 + 3 + 0 + 7 + 1 + 9 + 9 + 4 = 35 → 3 + 5 = 8. Your Bhagyank is 8.

Step 3: the number you are checking

Mobile number. We take the 10 digits (we remove +91, spaces and dashes) and add them all.

Example: 90000 12345 → 9 + 0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 5 = 24 → 2 + 4 = 6.

We also list the 9 digit pairs, reading left to right (positions 1-2, 2-3 and so on up to 9-10), any repeated digits, and any digits that are missing. Pairs are explained in Step 6.

Name. Each letter has a value. We add the values for your full name and for your first name, and show a letter-by-letter table. For now, names are entered in English letters (A to Z).

Chaldean values (our default). No letter has the value 9.

Pythagorean values (shown alongside, for comparison).

Example, the name RAVI:

• Chaldean: R 2 + A 1 + V 6 + I 1 = 10 → 1 + 0 = 1
• Pythagorean: R 9 + A 1 + V 4 + I 9 = 23 → 2 + 3 = 5

The two systems often give different answers. That is why we show both and tell you which one the score uses (Chaldean).

Vehicle number. We read Indian plates with or without spaces, including BH-series plates, and add the digits. We can also add the letters using Chaldean values. The result always shows exactly which digits and letters were counted.

Example: MH 12 AB 1234

• Digits only: 1 + 2 + 1 + 2 + 3 + 4 = 13 → 1 + 3 = 4
• Letters too: M 4 + H 5 + A 1 + B 2 = 12, and 12 + 13 = 25 → 2 + 5 = 7

Step 4: compatibility, from classical planetary friendships

Each number from 1 to 9 is linked with a planet:

Classical jyotish describes how each planet relates to the others. We show these relationships as favourable, neutral or challenging. The table is read across: it shows how your number (left) relates to the number being checked.

The columns list numbers after the Rahu and Ketu swap below: to look up 4, find 8; to look up 7, find 9. A number is always favourable with itself.

Rahu and Ketu

Rahu (4) and Ketu (7) are shadow planets and have no friendships of their own in the classical table. We follow a common convention: Rahu is read as Saturn (8), and Ketu as Mars (9), in both directions. Before every lookup, 4 becomes 8 and 7 becomes 9, whether it is your number or the number being checked.

What this means in practice:

• Mulank 1 and a number with root 4 → Sun and Saturn → challenging.
• Mulank 1 and a number with root 7 → Sun and Mars → favourable.
• 4 and 8 count as the same planet, and so do 7 and 9 → favourable.
• 4 and 7 → Saturn and Mars → challenging.

How the table is applied

1. Swap 4 for 8 and 7 for 9.
2. A number compared with itself counts as favourable.
3. Read the verdict from your row: how your Mulank or Bhagyank relates to the number being checked. The table is not always the same both ways. For example, Moon (2) treats Mercury (5) as favourable, but Mercury treats Moon as challenging. If your Mulank is 2 and the number is 5, the verdict is favourable. The maths appendix in your report shows both directions so you can see this for yourself. The other direction is only used to order numbers with equal scores (Step 5).

Step 5: scoring and ranking a comparison

Each number gets one verdict against your Mulank and one against your Bhagyank. Both count equally. We add up the points:

So each number scores between 0 and 6. This is the fit score in your report. A challenging verdict costs one point more than a neutral one, so favourable + challenging (3 points) ranks below neutral + neutral (4 points).

The highest score ranks first. When scores are equal, two more rules order them, in this order:

1. The reverse check. We read the same table the other way: how the number's planet relates to your Mulank and Bhagyank planets, with the same points. The higher reverse score ranks first. This never moves a number past one with a different score.
2. The Lo Shu fill. We count how many of the numbers missing from your Lo Shu grid (Step 7) appear among the number's digits. More ranks first: the number adds numbers your grid is missing. For a mobile number every digit counts; for a vehicle number, the digits that were counted for its total. Names don't use this rule.

If two numbers are still equal after both, they share a rank (for example 1, 1, 3). When first place is shared, you get joint top picks: by these rules they suit you equally well, so you can choose between them on price, convenience or anything else that matters to you. We don't break a tie with a rule that has no meaning in numerology. Inside a shared rank, numbers are listed by lower compound number so the order is always the same.

These weights are version 2.2.0 of our scoring data. If they ever change, the version number changes too, and your report's appendix always shows the version it used.

With one number, the report shows its full fit: both verdicts, the score out of 6 and the reasons. With 2 or more, it also ranks them.

Worked example. Date of birth 23/07/1994, so Mulank 5 (Mercury) and Bhagyank 8 (Saturn). The Lo Shu grid is missing 5, 6 and 8 (Step 7). Seven mobile numbers to compare:

How the order comes about:

• The first two both score 6. The reverse check separates them: Venus treats Mercury and Saturn as favourable (3 + 3 = 6), while Mercury treats Mercury as favourable and Saturn as neutral (3 + 2 = 5).
• The next three all score 5 and have the same reverse score. 96500 12300 contains 5 and 6, two of the numbers missing from the grid, so it ranks third. The other two contain none, so they share rank 4. 22 is also noted as a master number.
• 90000 12342 (neutral + neutral, 4 points) ranks above 90000 13339 (favourable + challenging, 3 points).

Step 6: digit pairs, for information only

Many people search for the meaning of pairs like 36 or 42 inside a mobile number. We list all 9 pairs in your number and give the meaning numerologists commonly discuss, labelled clearly: commonly discussed meaning; interpretations vary between numerologists.

Pairs have no effect on any score or ranking. There is no classical source for them, and different numerologists read them differently, so we keep them as information.

Step 7: the Lo Shu grid

The Lo Shu grid is a 3 × 3 square. We use the standard layout:

Each digit of your date of birth goes into its square. Zeros are skipped. Some numerologists also add the Mulank, Bhagyank or Kua number to the grid; we use only the digits of your date of birth.

Example, 23/07/1994. The digits are 2, 3, 0, 7, 1, 9, 9, 4:

• Missing numbers: 5, 6, 8
• Repeated numbers: 9 (twice)

We also show the rows and columns, often called planes. The rows are commonly named the mental (4-9-2), emotional (3-5-7) and practical (8-1-6) planes; names vary between books.

The Kua number: not used yet

We don't calculate the Kua number at the moment, because formulas differ between schools. If we add it later, we plan to use this common formula:

1. Add the digits of your birth year and reduce to one digit. Example: 1994 → 1 + 9 + 9 + 4 = 23 → 2 + 3 = 5.
2. For men: 11 minus that digit (11 − 5 = 6). For women: 4 plus that digit (4 + 5 = 9). Reduce again if the answer has two digits.
3. A result of 5 becomes 2 for men and 8 for women.

Some schools count people born before about 4 February as belonging to the previous year.

Where the calculation happens

• Free checks run in your browser. Your date of birth and numbers are not sent to us. Only anonymous usage events are counted (for example, "a mobile check was made"), never the numbers themselves.
• Comparison preview: totals, roots and Mulank verdicts are worked out in your browser.
• Paid comparison: the ranking is worked out on our server and your inputs are discarded straight after. Your report is saved in a private link on your device. If you lose it, you can recover it with the same inputs and your payment ID.

Versions

Our letter tables, friendship table and scoring weights are stored as versioned data. Every report's appendix lists the versions it used, so a report can always be checked against the rules that made it.
