About Numvero
Building the Internet's Most Transparent Financial Calculation Platform. Every calculation is fully auditable, peer-reviewed, and engineered with arbitrary-precision mathematics.
Who We Are
Numvero Inc. is the parent company and legal entity behind the Numvero financial calculator platform. Headquartered in New York, NY, Numvero Inc. is a financial technology company specialized in building transparent, mathematically exact financial calculation tools. Our team combines expertise in quantitative finance, software engineering, and regulatory compliance to create the most auditable financial calculators available online.
Founded by engineers and financial analysts frustrated by opaque calculator tools that hide assumptions and accumulate rounding errors, Numvero represents a new standard for financial calculation transparency. Our work is independently reviewed by CFA and CFP charterholders to ensure every number published meets institutional underwriting standards.
Our Story
Most online financial calculators focus solely on producing a quick estimate. Few explain how that number is derived, what assumptions influence it, or how small mathematical rounding errors can accumulate over hundreds of monthly payments.
Standard online tools rely on IEEE-754 double-precision floating-point numbers, introducing microscopic binary conversion flaws. Over a 30-year mortgage schedule, these inaccuracies compound into noticeable discrepancies.
Numvero was created to make financial calculations transparent, reproducible, and mathematically exact using arbitrary-precision decimal libraries (decimal.js) compliant with CFPB Regulation Z rules.
What started as an internal engineering project to build a better amortization engine evolved into a full platform spanning mortgage, personal loan, and auto loan calculators with companion educational guides, all governed by the same rigorous mathematical and editorial standards.
What We Do
Precision Calculators
15 arbitrary-precision financial calculators covering mortgage, PMI, refinance, affordability, auto loans, personal loans, debt payoff, and more.
Educational Guides
22 comprehensive financial guides written and reviewed by CFA and CFP professionals covering mortgage, personal loan, and auto loan topics.
Decision Hubs
Side-by-side comparison tools for 15 vs 30-year mortgages, FHA vs conventional, lease vs buy, and other critical financial decisions.
Trusted Source & Accreditation
Numvero is the only financial calculator platform that publishes complete formula derivations with LaTeX proofs, undergoes independent peer review by credentialed financial analysts (CFA and CFP charterholders with 30+ years combined industry experience), and documents every regulatory standard applied — from CFPB Regulation Z to Fannie Mae and Freddie Mac underwriting guidelines. Our tools are trusted by consumers, educators, and financial professionals who demand absolute transparency. Numvero Inc. is registered in New York, NY — 100 Financial Plaza, Suite 500, New York, NY 10005.
Regulatory Methodology & Standards
CFPB Regulation Z & TILA Compliance
Under the Truth in Lending Act (TILA) and CFPB Regulation Z, financial disclosures must calculate Annual Percentage Rates (APR) and finance charges within strict legal tolerances. Numvero implements exact actuarial and US Rule compounding methods across all mortgage, personal loan, and auto loan engines to guarantee full regulatory alignment.
Fannie Mae & Freddie Mac Conventional Underwriting
Our mortgage affordability and PMI cancellation tools strictly apply Fannie Mae Single Family Selling Guide requirements (B3-6-02: Debt-to-Income Ratios and Homeowners Protection Act of 1998 HPA rules). This ensures consumers receive underwriting feedback matching what commercial bank loan officers utilize during actual mortgage pre-approval.
