We know that net worth means the total value of all your assets minus all your liabilities. You need to calculate it at least once a year. You may use an online calculator or you can go to a financial planner to find out your net worth of yours. It is better if you calculate it yourself rather than using a financial advisor because he/she may not be aware of your assets and liabilities. So, it is very important that you know about your how worth?. If you are planning to become a doctor then you need to calculate the expenses that you need to bear along with the salary. If you are planning to become an entrepreneur then you should also calculate the cost of starting a business. So, you need to know what kind of money you have to earn and you also need to know how much you need to earn to live a happy life.
