How to Calculate Your Kua Number: A Complete Guide for 2026

by Hailee Mercer on Mar 05, 2026

Quick answer: To calculate your Kua number, add the last two digits of your birth year and reduce them to a single digit. Men then subtract that digit from 10 (or from 9 if born in 2000 or later); women add 5 to it (or 6 if born in 2000 or later) and reduce again to a single digit. If the result is 5, men use 2 and women use 8, because there is no Kua number 5. One important detail: Feng Shui follows the lunar calendar, so if you were born in January or early February before the Lunar New Year, use the previous year. Your final number—1, 3, 4, or 9 for the East Group; 2, 6, 7, or 8 for the West Group—reveals your four most auspicious directions for sleeping, working, and arranging furniture at home.

In the world of Feng Shui, your personal Kua number (also known as the Gua number) is the key to unlocking a harmonious living environment. Whether you are redesigning your bedroom or optimizing your home office, understanding your Kua number allows you to align your furniture with your most auspicious directions. At wehomz, we believe that a well-designed home is not just about aesthetics—it is about creating a space that supports your energy and well-being.

What is a Kua Number?

Your Kua number is a unique digit based on your birth year and gender. It is derived from the Eight Mansions (Ba Zhai) school of Feng Shui. This number categorizes individuals into two groups: the East Group and the West Group. Each group has four favorable directions and four unfavorable ones. By knowing your number, you can position your bed, desk, and sofa to attract wealth, health, and success.

"The Kua number is essentially your personal energy blueprint. It tells you how you interact with the magnetic fields of the Earth." — Feng Shui Research Center [1]

Feng shui carries real weight in housing decisions: in a national survey by Better Homes and Gardens Real Estate and the Asian Real Estate Association of America, 86% of Chinese-American respondents said feng shui will play a role in their future home buying choices.

How to Calculate Your Kua Number: Step-by-Step

Calculating your Kua number is a simple mathematical process. However, the formula differs slightly for males and females, and there is a specific adjustment for those born after the year 2000.

Step 1: Determine Your Lunar Birth Year

Feng Shui follows the Lunar calendar. If you were born in January or early February (before the Lunar New Year), you should use the previous year for your calculation. For example, if you were born on January 15, 1990, your birth year for this calculation is 1989.

Step 2: The Calculation Formula

For Males:

1.Add the last two digits of your birth year. If the result is a double digit, add them again until you get a single digit.

2.Subtract that single digit from 10 (if born before 2000) or from 9 (if born in or after 2000).

For Females:

1.Add the last two digits of your birth year and reduce to a single digit.

2.Add 5 to that digit (if born before 2000) or add 6 (if born in or after 2000).

3.If the result is a double digit, add them together to get a single digit.

Important Note: The Number 5

In the Kua system, there is no Kua number 5.

•If a male calculates a 5, his Kua number becomes 2.

•If a female calculates a 5, her Kua number becomes 8.

Applying Your Kua Number to Your Home Decor

Once you have identified your personal kua number and your birth element, you can start making strategic changes to your home. Here is how to use this knowledge with wehomz furniture:

1. The Bedroom: Better Sleep and Relationships

Your bed should ideally face one of your four lucky directions. For instance, if your Kua number is 1, facing North while sleeping can enhance your personal growth.

•Tip: Use a solid headboard from our [wehomz Bedroom Collection] to provide stability and support.

•Avoid: Placing your bed directly in line with the door, known as the "coffin position."

2. The Home Office: Productivity and Wealth

Position your desk so that you face your "Sheng Chi" (Success) direction while working. This is particularly important for entrepreneurs and remote workers.

3. Living Room: Harmonious Gathering

Arrange your seating to encourage positive energy flow. Use the Bagua map to determine which colors and materials best suit each corner of your living room.

"If you're sitting up in bed with your back against the headboard, you would want to be able to see the door without being directly in line with it."

— Anjie Cho, feng shui consultant, architect, and author of *Holistic Spaces*

With 75% of U.S. workers who hold remote-capable jobs now working from home at least some of the time (Pew Research Center, 2025), your desk orientation matters more than ever. (Source: Pew Research Center (survey conducted Oct 7–13, 2024, published Jan 2025))

Getting your sleeping direction right is not a trivial pursuit—according to CDC data compiled by USAFacts, 36.1% of American adults report getting less than the recommended amount of sleep. (Source: USAFacts (CDC Chronic Disease Indicators data))

Understanding Your Birth Element

Your Kua number is closely tied to your birth element (Water, Wood, Fire, Earth, or Metal). Incorporating these elements into your decor can further balance your home's energy.

•Water (Kua 1): Use blue tones, mirrors, and fluid shapes.

•Wood (Kua 3, 4): Incorporate plants and wooden furniture.

Frequently Asked Questions

What is my Kua number if I get 5 in the calculation?

There is no Kua number 5 in the Eight Mansions system. If your calculation results in 5, use Kua 2 if you are male and Kua 8 if you are female. Both substitute numbers belong to the West Group, so your favorable directions become Southwest, Northwest, West, and Northeast.

Does my Kua number ever change?

No. Your Kua number is fixed for life because it is based on your birth year and gender. What can change is how you apply it—as you move homes or rearrange rooms, you re-orient your bed, desk, and seating to keep facing your four favorable directions.

What is the difference between the East Group and the West Group?

Kua numbers 1, 3, 4, and 9 form the East Group, whose lucky directions are East, Southeast, North, and South. Kua numbers 2, 6, 7, and 8 form the West Group, favoring West, Northwest, Southwest, and Northeast. Each group's favorable directions are the other group's unfavorable ones.

Which birth year do I use if I was born in January?

Use the previous calendar year. Feng Shui follows the lunar calendar, and the Feng Shui new year typically begins in early February. For example, if you were born on January 15, 1990, calculate your Kua number with 1989 instead of 1990.

What if my partner and I have different Kua groups?

This is common. A practical compromise is to orient the bed to favor the main breadwinner's Sheng Chi direction, or to choose a direction that is at least neutral for both partners. Each person can still individually face their own lucky direction at their desk or reading chair.

The same BHGRE/AREAA survey found buyers who value feng shui are willing to pay an average of 16% more for a home that complies with its principles—evidence that an aligned home is seen as a genuine asset. (Source: Better Homes and Gardens Real Estate / AREAA national survey)
