Formula of Wealth

As we're in process to build wealth tonight, we should put some thought on what does wealth really means to us? How is it calculated? I put in some thought and want to share this simple formula of wealth which make sense to me.

Wealth= ((Money + Time) * Return) - (Inflation + Tax)

This formula apply both investing and starting a business. As you can see, one must put in either time or money, not necessarily both, as our initial contribution to build our wealth. Without either of these two components, wealth can hardly be built. The money is the amount you willing to set aside to invest or start a business. The time is the amount of time you willing to spend to do things that could help you closer to your financial goal, ex, reading my blog (529pm) :D ! The return could be postive or negative. Different vehicle offer different return, we just have to train ourselves to select the best one match our objective and yield the highest postive return. Inflation is a factor which we can't do much to control. It varies from countries to countires, in U.S, we're sitting around 4% a year. TAX is another big enemy which will erode our wealth. We must always think how to legally and ethically reduce the tax effect from the build wealth formula. There you have it, does it makes sense to you?
