How FigureNorth builds calculators
Defined logic, tested inputs, and visible context
Each calculator is built around explicit formulas or defined calculation logic. Tool pages show assumptions, explanations, worked examples, or formulas where they help users understand a result.
Formula and logic
Inputs are connected to a defined calculation, with assumptions shown where relevant.
Development checks
Calculation logic is reviewed during development, with common inputs and boundary conditions checked where relevant.
Regional context
U.S. and Canadian logic is separated only in tools where that difference affects the result.
Calculations and estimates
Defined calculations can be exact for the values entered; planning estimates depend on their assumptions.
Always review the inputs, units, assumptions, and notes shown on the individual tool before using its result.
Useful for planning, with clear limits
FigureNorth tools are for informational and planning use. Results may not capture every personal, local, or professional requirement. Verify important financial, medical, legal, or project decisions with an appropriate qualified professional.
