I built ReliabilityBench because reliability and maintenance calculations are often scattered across spreadsheets, software documentation, and isolated calculator pages. The goal was to create one practical workbench where engineers, maintenance teams, asset managers, and MRO professionals can calculate metrics such as MTBF, MTTR, availability, OEE, system reliability, Weibull life estimates, downtime cost, maintenance ROI, and spare-parts requirements. ReliabilityBench currently includes 29 free calculators, along with guides and formula references. Each tool explains its inputs, formula, assumptions, limitations, and how to interpret the result in a real maintenance or asset-management context. No account is required. I would especially appreciate feedback from people working with industrial equipment, maintenance planning, reliability analysis, or spare-parts inventory.
