How we approach the math
- Use common business formulas that can be verified by hand.
- Round percentages to 2 decimal places and money to 2 decimal places.
- Use plain English to explain what each result means.
Methodology
Transparent formulas, practical explanations.
These calculators are designed to keep the math visible, make assumptions easy to check, and give a result that is useful for planning rather than just filling a box.
What these tools do not do
- They do not replace accounting, tax, or financial advice.
- They do not make legal, pricing, or investment decisions for you.
- They do not predict outcomes beyond the numbers you enter.
