Specialty calculators
Test a plan with the decision feasibility calculator, or choose construction dimensions, finance, data, algebra, cutting layouts, air properties or machining. Scientific and graphing tools are here too.
Scientific calculator
Expressions, trigonometry, memory and numerical functions.
Open workspace →Graphing calculator
Function plots, sliders, tables and chart exports.
Open workspace →Decision feasibility calculator
Use this decision feasibility calculator for feasibility studies, go/no-go analysis, decision matrices, cost-benefit analysis and opportunity scoring with explicit uncertainty.
Open workspace →Construction calculator
Use this construction calculator for feet, inches and fractions, right-triangle dimensions and equal stair-rise layouts.
Open workspace →Financial calculator
Use this financial calculator to solve time-value-of-money unknowns and evaluate cash-flow NPV and IRR with explicit signs and payment timing.
Open workspace →Statistics calculator
Use this statistics calculator to summarize data, fit linear regression models and calculate normal or binomial probabilities with visible assumptions.
Open workspace →Algebra and matrix calculator
Use this algebra and matrix calculator to solve quadratic equations and linear systems, multiply matrices, and calculate inverses and determinants.
Open workspace →Cutting layout optimizer
Use this cutting layout optimizer to plan linear stock cuts and rectangular sheet layouts with blade width, edge trim and rotation options.
Open workspace →Psychrometric calculator
Use this psychrometric calculator to find humidity ratio, dew point, wet-bulb temperature and air enthalpy from measured conditions.
Open workspace →Machinist calculator
Use this machinist calculator to convert supplied cutting speed to RPM and calculate milling or drilling feed rates and travel time.

These workspaces are separate from the 331 business worksheets in the calculator library. Their calculations, printouts and result downloads are free. They are not currently sections in paid comparison or project reports. Inputs stay in your browser tab; nothing is saved automatically.
Each workspace shows its supported methods, worked example, input definitions and limits. We build original interfaces around established mathematics; no other calculator brand endorses BusCalc.
