Finance tools — FAQ
- How accurate are the finance calculators?
- They use the same standard formulas banks and accountants apply. Because tax rules differ by country, you set the rates so the output matches your jurisdiction.
- Are the finance tools free to use?
- Yes. Every AIPULY tool is free, with no sign-up, no usage caps and no watermarks on anything you export.
- Do you store the values I enter?
- No. Calculations run in your browser, so the numbers and text you type never leave your device.
- Can I use the results commercially?
- Yes. Results, exports and generated files are yours to use in client work and internal reporting without attribution.
