Tolerance Stack-up Calculator Online

Considers complex geometric tolerances (GD&T) and variations in multiple planes or 3D space. 3. Step-by-Step Calculation Logic

Choose between Worst-Case or RSS (Statistical). Some advanced calculators allow for "Modified RSS" (including a safety factor) or Monte Carlo simulation (using random number generation to predict thousands of assembly outcomes). tolerance stack-up calculator

When you save your calculation file, note the temperature conditions (parts expand when hot) and the assumed process capabilities (Cp/Cpk). A stack-up analysis is useless if the manufacturing floor is producing parts with a centered mean, but your calculator assumed a shifted mean. tolerance stack-up calculator

To understand how a calculator processes data, let us look at a linear stack-up calculation for a simple pin-and-housing assembly.
