About the tools
Figures you can follow line by line
Check the Figures gives business owners fast, unmediated access to core financial math. Every calculator shows its inputs and its result side by side, so the numbers stay in view.
Free
To use every calculator, with no subscription or ad clutter
Inputs sit on the left, results on the right, and each formula is written out so you can check the arithmetic yourself.
Our conviction
Financial figures should be visible, legible, and verifiable.
Built to provide straightforward numerical clarity without subscription models or ad clutter. Every result should trace back to inputs you can see and change.
Technical standards
Standard formulas, stated rounding
Formulas follow standard corporate finance accounting and operational economics conventions. Each variable is defined beside its input, so the method is visible before you trust the result.
Computation safeguards
Each calculator validates inputs before it runs, and flags values that fall outside a sensible range. Results update as you change a figure.
Rounding and variables
Results display at a stated precision, and every variable carries a plain definition. The same inputs always produce the same figure, on every page of the site.
