How we ensure accuracy, transparency, and data integrity in every calculation.
At Hesaplamasyon, calculations are never black boxes. Every tool is engineered on verified statutory frameworks, peer-reviewed mathematical formulas, and rigorous client-side execution.
1. Official Sources & Regulatory Alignment
Our financial and tax engines integrate statutory parameters published by central authorities including the Central Bank (CBRT), Banking Regulation and Supervision Agency (BRSA), Revenue Administration (GİB), and Social Security Institution (SGK). When official tax brackets or interest cap regulations update, our formulas are immediately re-benchmarked.
2. Open Formula & Explainable Results
We believe users have the right to understand exactly how their numbers are derived. Each calculation page provides step-by-step formula breakdowns, applied deduction ratios, and comprehensive explanatory guides written by subject matter specialists.
3. 100% Client-Side Privacy (Zero Data Logging)
Your financial inputs, salary numbers, loan amounts, and health metrics are processed entirely within your device’s browser. We do not store, transmit, or monetize your sensitive computation data on remote databases.
4. Automated Verification & Continuous Testing
All calculator modules undergo strict unit testing and edge-case boundary checks (e.g. zero inputs, negative values, leap years, rounding precision). We verify results against official benchmark simulators to guarantee zero rounding discrepancies.
Methodology Standards by Category
Finance & Banking
Loan calculations utilize standard French Amortization annuity formulas. Total cost figures rigorously account for monthly compound interest, BSMV (Banking and Insurance Transactions Tax), and KKDF (Resource Utilization Support Fund).
Tax & Payroll
Income tax calculations strictly implement progressive cumulative tax brackets. Minimum wage exemptions, employee SGK rates (14%), and unemployment insurance contributions (1%) are applied according to statutory laws.
Health & Biometrics
Body Mass Index (BMI) and metabolic calculations adhere to World Health Organization (WHO) and Harris-Benedict formulas. Ideal weight and caloric targets are presented with clinical context.
Hesaplamasyon is designed as an independent planning and analytical tool. Calculations, simulation outputs, and guide contents are provided for general educational and decision-support purposes. While we strive for absolute accuracy, our tools do not constitute legally binding financial, tax, or legal advice. Users are encouraged to consult certified public accountants or financial institutions for binding commercial transactions.
