Meet the Team
Daniel Agrici — Math & Finance Writer
Daniel founded NovaCalculator and leads development of the mortgage, loan, and investment calculators. He focuses on financial modeling, interest calculations, and investment analysis, checking formulas against sources such as IRS publications and Federal Reserve guidance before they go live.
Sher — Fitness & Nutrition Specialist
Sher oversees the calorie, macro, and body-composition calculators, focusing on turning published fitness and nutrition research into practical tools. Calculators in this category are checked against guidance from the American College of Sports Medicine and the Academy of Nutrition and Dietetics.
Rahul Singh — Health & Wellness Researcher
Rahul focuses on clinical health metrics, medical reference ranges, and preventive wellness tools such as BMI, blood pressure, and medication dosing. He works with the editorial team to flag outdated guidance and update calculators whenever medical standards change, referencing published clinical literature.
Sahil — Senior Editor & Finance Reviewer
As Senior Editor, Sahil coordinates the review cycle every calculator passes through before publication and focuses on personal finance, tax planning, and retirement projections. He checks calculator outputs against current tax codes and regulatory frameworks as part of that review.
Manoj Kumar — Mathematics Educator
Manoj is responsible for the pure math and conversion calculators, focusing on making algebraic, geometric, and statistical tools both correct and easy to follow. He writes the explanatory content that accompanies each calculator so users can see the underlying formula, not just the result.
Abdullah — Technical Content Specialist
Abdullah reviews the visa & immigration, date & time, and construction & engineering calculators, checking figures such as visa fees, processing timelines, and material specifications against publicly published government and industry sources. NovaCalculator's immigration and legal calculators are informational only — each one carries a disclaimer pointing users to a licensed immigration attorney or other qualified professional for advice specific to their situation.
Raz Mohammad — Tax & Salary Specialist
Raz maintains the salary, take-home pay, and tax bracket calculators, focusing on payroll, income tax, and compensation across multiple jurisdictions. He updates these tools annually to reflect legislative changes so withholding and deduction scenarios stay current.
Our Review Process
Every calculator published on NovaCalculator passes through a structured multi-step review before going live. First, the subject-matter specialist writes and validates the core formula against authoritative primary sources — government publications, peer-reviewed journals, or recognized professional standards. Second, a second team member independently verifies the calculation with manual test cases covering typical and edge-case inputs. Third, the Senior Editor reviews the accompanying explanatory text for clarity, accuracy, and appropriate disclaimers. Only calculators that pass all three stages are published. Existing calculators are re-reviewed whenever underlying guidelines, tax rates, or medical recommendations change.
Accuracy Standards
Different calculator categories are held to the standards of the relevant governing body or authoritative reference in their domain.
- › Financial calculators are verified against IRS publications and Consumer Financial Protection Bureau (CFPB) guidelines. Tax bracket figures, contribution limits, and penalty thresholds are reviewed and updated annually following each tax year's official IRS announcements, ensuring results always reflect current law rather than prior-year rates.
- › Health calculators are verified against clinical reference ranges published by the World Health Organization (WHO) and the National Institutes of Health (NIH). Our team monitors major guideline updates and applies revisions within 30 days of official publication to keep outputs aligned with current medical consensus.
- › Unit conversion calculators use base values defined by the National Institute of Standards and Technology (NIST), ensuring all conversions are traceable to SI definitions and do not accumulate floating-point drift at practical precision levels.
- › Engineering calculators are verified against published industry specifications, including relevant IEEE, ASME, and ASTM standards where applicable. Tolerances and safety factors are noted explicitly in calculator descriptions so users understand the assumptions built into each result.
