How we calculate.
Numbers should not be a black box. We explain the formulas, units, assumptions, and limitations that shape each result.
Read our full methodology- Defined methods: Each tool starts with a stated formula or conversion relationship suited to a general estimate.
- Input checks: Required, invalid, boundary, and unit-sensitive values are checked where the calculation needs them.
- Useful rounding: Results are formatted for their context, so displayed values may be rounded from the underlying calculation.
- Clear limits: Assumptions and omitted real-world factors explain when to verify an estimate elsewhere.
