About Fynvorax

Davi Baptista — Founder & financial tools editor

Fynvorax publishes free financial calculators and in-depth guides for US-style planning: HELOC payments, mortgage refinance break-even, S-Corp tax modeling, lease buyout math, crypto capital gains estimates, and more. Every guide links to a runnable tool so you can verify numbers in your browser without creating an account.

Fynvorax is operated independently by Davi Baptista (Founder & financial tools editor). The site launched in 2026 to offer transparent, privacy-first planning tools with clear disclaimers—not personalized advice from a licensed professional.

We fund the site with Google AdSense display advertising only—no paid affiliate links on calculator pages. You choose whether to allow personalized ads in our cookie banner. We never sell your calculator inputs or require payment to use the tools.

How we create content

Calculator formulas and defaults are built and maintained by Davi Baptista—not outsourced widget embeds. Each tool documents its math on the page. Guides are drafted with AI assistance for structure and clarity, then tied to a runnable calculator, US planning concepts, and public references (IRS publications, CFPB auto-loan guidance, etc.). We do not publish mass-generated pages without a matching tool. Priority guides get worked examples and FAQ blocks; we update the “last reviewed” date when formulas or guidance change. This is educational content—we are not CPAs, attorneys, or lenders.

Content standards

• Use standard financial formulas documented on each calculator page (amortization, compound interest, break-even, etc.).
• Priority calculators include long-form US guidance (400+ words), FAQs, and HowTo schema—not thin widget pages.
• Label outputs as estimates; real lender, tax, and market outcomes vary.
• Update anchor calculators and guides when formulas or US planning assumptions change.
• Separate editorial content from advertising—ads are clearly marked third-party placements.

Editorial policy

Guides and calculator pages are for education, not personalized tax, legal, or investment advice. Calculator logic is hand-maintained; guides may use AI-assisted drafting but are always linked to a runnable tool and checked against public sources (IRS, CFPB, etc.). We use standard financial formulas, explain US planning concepts where relevant, and update pages when methods change. Advertising (Google AdSense) is separate from editorial content. Report errors via Contact—we correct verified issues promptly.

Our Mission

Free calculators for real decisions—loans, compound growth, retirement, rent vs buy, and more.

Our Methodology

Transparent formulas with daily, monthly, and yearly compounding—same math you would use in a spreadsheet.

Our Standards

Calculations run in your browser. We do not store your balances or salary on our servers.
