The invention provides a forecasting method of the total resistance of an actual ship. The forecasting method of the total resistance of the actual ship is based on that if the Froude number and the shape factor 1+k of a mother ship are equal to that of an actual ship to be measured, and the geometry of the mother ship and the geometry of the actual ship to be measured are like, the relationship between the actual ship to be measured and the mother ship meets the condition that a ratio of total resistance coefficients, calculated through CFD, of two actual ships is equal to a ratio of total resistance coefficients, obtained through ship model tests, of the two actual ships, so the total resistance coefficient of the actual ship can be calculated. The forecasting method of total resistance of an actual ship combines the reliability of a ship model test and the economical efficiency of CFD technology.
