Our Calculation Methodology
Every calculator on OmniMetrics Hub is built upon transparent, published mathematical formulas, executed entirely client-side, and verified against standard financial accounting conventions.
Methodological Pillars
100% Client-Side
Calculations occur locally in your browser’s JavaScript engine. Zero financial figures or user inputs are transmitted to external servers.
Deterministic Math
Every formula produces repeatable, verified outputs consistent with GAAP conventions, standard loan amortization schedules, and merchant fee schedules.
Zero Data Harvesting
We do not track, store, or sell user calculations. Your financial model, profit figures, and personal rates remain strictly confidential.
Computational Precision & Rounding Conventions
To maintain accuracy across currency conversions and multi-step equations (such as compound interest and loan amortization), internal calculation pipelines retain full 64-bit floating-point precision throughout intermediate operations.
Final user-facing values are rounded strictly at display-time to 2 decimal places (or integer units where applicable) following standard half-up arithmetic rounding rules.
Standard Numerical Verification Checklist
- Intermediate variables are never truncated before compound calculations complete.
- Division-by-zero safeguards and input bounds validation prevent non-finite display states.
- Tiered fee calculations (such as Stripe / PayPal merchant pricing) apply fixed and variable fee components independently.
Formula Transparency & Peer Review
We publish complete formula breakdowns and educational step-by-step guides for every single calculator in our Knowledge Base. If you notice any discrepancy or wish to propose an updated merchant rate schedule, contact our quantitative engineering team.
