Provided is a photoelectric digital magnetic suspension display ball for a financial bubble and a calculation method for the financial bubble. A top plate of a base of the photoelectric digital magnetic suspension display ball for the financial bubble is a circular photoelectric digital LED panel, and the display ball thereof is a magnetic suspension ball which displays characteristics of the financial bubble by applying photoelectric digital technology and magnetic suspension technology. The information of the financial bubble is displayed in the center of the photoelectric digital display panel, a cash value spectrum of the financial bubble is displayed in a multi-layer concentric circle, and audio information of the financial bubble is issued on a magnetic suspension ball by Bluetooth technology. Flying cash is real principal without interest or depreciation. However, in the modern financial cash flow environment, flying cash is calculated as the principal. When flying cash increases the calculation of the principal, the calculation of interest and depreciation is also increased. The flying cash serving as the added value of the interest and depreciation which are brought about by increasing calculation of the principal is the financial bubble. Hence, the authenticity of the financial bubble is related to the calculation of compound interest of flying cash, and the financial bubble will disappear as the calculation of compound interest of flying cash disappears.
