Address Numerology Calculator

Which characters does the address calculator count?

Digits and the letters A to Z. Digits count at face value. Letters use the Pythagorean table, which runs A to I as 1 to 9, J to R as 1 to 9 and S to Z as 1 to 8. Spaces, hyphens, slashes, commas and accented letters are dropped before adding, so “Flat 7” is read as F, L, A, T and 7, not as 7 alone. Type only the number and any unit letter, such as 7B.

Why does 42A come out as 7?

Because 4 + 2 + 1 = 7, with the letter A worth 1. The total is already a single digit, so no reduction is needed. The Property number row uses the house or flat field only. The street name never changes it.

How is the street name combined with the house number?

The street name is turned into its own number first: its letters are added and reduced, stopping at 11, 22 or 33. That reduced street number is then added to the unreduced house total and the sum is reduced again. For 12 Example Street the house total is 3, Example Street adds up to 55 and reduces to 1, so the full address number is 3 + 1 = 4.

What happens with master numbers?

The reduction stops at 11, 22 and 33 instead of continuing. A flat 29 gives 2 + 9 = 11 and is shown as 11 with its own master-number text. A total of 33 has an entry as well. If a street reduces to 11 or 22, that master value, not its single-digit form, is what gets added to the house total.

Does the calculator know about postcodes, building numbers or floors?

No. It reads only the two text boxes. A postcode, floor number or building name is counted only if you type it into one of them, and then every letter and digit in it is added. The tool does not validate that the address exists.

What are “Best suited for”, “Watch out for” and the interior tip?

They are fixed lines of text stored for each of the twelve possible numbers (1 to 9, 11, 22 and 33). Two different addresses that reduce to the same number get identical text. Nothing is assessed about the people who live there or the building itself.

Does the street change the first reading?

No. When a street is entered, two extra rows are added: the full address number and its energy label. The first six rows are always based on the house or flat field alone.

Can this tell me whether a home is a good place to live?

No. It adds characters and looks the total up in a table. It says nothing about condition, safety, neighbours, price or fit.
