Mars in the 8th House: 5 Ways it Can Affect You

Mars in the 8th House

When Mars is in your 8th House, financial growth happens through action and ambition. You are very passionate about the things you do. You have a lot of energy and you have to find ways to let it out. You are afraid of letting people close to you.

To understand what it means when a planet lands in a house on your natal chart, you need to look at the meaning of the house, meaning of the planet, and how they interact:

  • The 8th House represents fears, the things in our life we have no control over, shared assets, investments, loans, debt. It also represents our sexuality, the person we are in our private life, who we are in secret.
  • Mars is the planet of action, force, energy and sexuality.
  • When Mars is in the 8th House, you are protective of yourself. You are likely to go through big changes throughout your life. You can be very private with your plans and actions. Financially, you are likely to experience financial growth, but avoid taking big risks.

Note that this is just one facet of your natal chart. Other elements of your natal chart can overpower or contradict with the below points. To get an accurate interpretation, get a holistic reading of your full natal chart from an astrologer.

Also note that astrology does not intend to be deterministic and acknowledges the power of factors like freewill, genetics, and life experiences in influencing your personality, making the below information broad brushes only that may or may not suit your personal situation.

What Does it Mean when Mars is in the 8th House?

8th House Meaning

The 8th house tells us about our finances – especially ones we share with other people. It represents shared assets with a partner and inheritance.

 It represents our investments – what we put our money into, how we deal with money. It can show loans and debt, it can show financial struggles or gains.

We learn a lot about our intimate relationships. How we deal with intimacy, how easily we allow other people in our life and close to ourselves. It shows the hidden or secretive side of us.

The 8th House is also connected to the things we keep private in our life, the things we have a hard time talking about in front of others people. It shows the things we view as taboo or danger.

The house is connected to regeneration – the personal transformation we go through in our life.

The Meaning of Mars

Mars is one of the most important planets in a person’s Natal Chart. It is one of the personal planets and it represents an important part of a person’s life – how they take action, how they express their energy and anger.

Mars is the planet of force and destruction. It shows us how we react when we face unpleasant circumstances. It tells us how willing we are to fight our problems and overcome them. It signifies how we express our energy and where we put it into.

Mars can signify sexuality and passion. It can point to the way we express our passion, how protective and careful we are with the things we love.

Mars is the planet of violence, of lies and aggression. When it is too prominent in a person’s chart it can show a dominant character, a strong personality and a tendency for violence. It can show how competitive we are with others, how willing we are to complete the things we start. Mars can bring chaos and frustration.

Mars in the 8th house can show a person who is very financially ambitious. Earning money may come through risk and action, but they have to avoid being too reckless and impulsive. They prioritize their privacy and are fearful of betrayals. Transformation happens when they gain courage and take action.

5 Things Mars in the 8thHouse Signifies

1. You are vengeful

When Mars the planet of aggression and violence is in the 8th house of hidden and secretive matters it shows that you are likely to be very private about your plans when someone has done you wrong.

You are vengeful and you have difficulty forgetting betrayals or anything bad other people have done to you.

You seek revenge and you may have a hard time moving on unless the other person experiences the same difficulty as you did. Sometimes your revenge may take years and it can become an obsession of yours. In order to deal with that, you must learn to move on and let karma do its job.

2. You make bold financial moves

You are unafraid to take risk when dealing with money. At times this can show a lot of risky financial moves that can possibly lead to unpleasant outcomes.

Trusting other people with money is unlikely.

Money and financial abundance may enter your life once you learn to take risk, but also be conscious of that risk. Do good research on your plans and avoid allowing others to make financial decisions for you.

3. You are magnetic

Mars in the 8th house of sexuality can show a very magnetic and passionate nature. You have strong sexual energy and you have no problem attracting others.

 You are mysterious and people are intrigued by you.

You are not easy to get and you may enjoy playing mind games – you enjoy difficulty, you don’t allow people to get close to you that easily.  This can make other people frustrated and even more attracted to you or it can make them give up easily on your relationship.

4. You enjoy risk

Mars in the 8th house can show a love for danger and action. You are passionate about activities that push your limits, take you out of your comfort zone and allow you to experience new things.

You are drawn to danger and you may often participate in activities that other people wouldn’t.

You can be attracted to dangerous sports, do risky activities, go out with people who are unfamiliar but intrigue you. You are likely to have many near death experiences and there can be a lot of scary moments in your life. Learn to find better balance between danger and adventure.

5. Transformation comes with action

When Mars the planet of action is in your 8th house of transformation it shows that the big changes in your life come when you take action, when you make bold moves and take risks.

You have to let go of the things that hold you back and embrace the new that await you.

Despite your love for danger, you can have a hard time getting out of your comfort zone, so try to be patient when making changes.


With Mars in the 8th House of your natal chart, you keep your energy private and you are protective of yourself. You make plans and take action in secret. You have difficulty trusting other people and find it hard to allow people close to you. Financially, you are ambitious and driven to make money in various ways. Remember that you need to look at the rest of your natal chart to make a better prediciton of your natural personality traits. Other elements on your natal chart may override some of these points (and I’ve tried to note that a few times in this article).
