Calculators and converters
Risk: Assumption mismatch
What it is
A documented, standard formula applied to the numbers you entered, at the precision the tool exposes.
What it is not
- The convention your jurisdiction, contract or institution actually uses — those differ for the same-sounding calculation.
- A forecast. A projection is arithmetic on your assumptions, and it inherits every one of them.
- Precision-independent. Where a tool exposes a rounding control, the displayed answer depends on it.
Before you rely on it
Check which convention applies to your case, and re-run with the rounding your counterparty uses.
