How our tools work
We don't hide the math. Every calculator shows its assumptions, sources, and limitations.
Transparent assumptions
Every default value is based on real data. You can see and adjust all assumptions.
Range-based estimates
We show ranges (low/typical/high) because single-point estimates are misleading.
No data collection
Calculations run in your browser. We don't store your inputs or require login.
