The article is devoted to different formulas, describing the equation of pile load capacity. The most part of current building projects, ranging from country houses to high-rise building, utilizes various types of pile foundations. Today exists a broad practice of designing piles and calculating pile load capacity, such as pyramidal, fundex, caisson piles etc. This brings the immense actualityto the universal methods of estimating these loads and verifying results. This approach should be based on a deep understanding of physical and mechanical principals of the process. Basing on the analysis of scientific literature and the common practice of pile load capacity equation, we introduce a universal formula to estimate pile load capacity for all types of piles. The resumptive formula may be widely used in different building projects and as an effective tool while developing engineering computer applications.
