Data Sources & Methodology
FreeCurrencyTool.com is committed to transparency, accuracy, and responsible financial education. This page explains the data inputs, calculation logic, update frequency, and limitations behind the calculators available on this website.
Calculation Methodology
All calculators on FreeCurrencyTool.com use deterministic mathematical formulas commonly accepted in finance, economics, and accounting. Calculations are performed client-side in the user’s browser using predefined formulas rather than automated decision-making systems or predictive models.
- Loan and mortgage calculators use standard amortization formulas
- Interest and investment tools apply compound interest equations
- Debt and credit estimators rely on user-supplied inputs only
- Currency conversions apply real-time or near-real-time exchange rates
Data Sources
External data inputs are limited and used only where necessary. Sources may include:
- Publicly available financial reference data
- Widely recognized exchange rate providers
- Manually maintained reference values updated periodically
No personally identifiable information is collected or stored as part of calculator usage.
Update Frequency
Calculation logic is reviewed and updated periodically to reflect current financial standards. Currency exchange data is refreshed automatically where applicable, while fixed calculators operate using static formulas.
Limitations & Assumptions
Calculator results are estimates only. Actual financial outcomes may vary based on lender terms, fees, taxes, regional regulations, market conditions, and other external factors.
Users are encouraged to consult qualified financial professionals before making financial decisions.
