PlainFig was built on a simple premise: personal finance tools should provide honest, exact numbers based on verifiable statutory sources—without deceptive marketing, paywalls, or lead-generation traps.
Who Builds PlainFig
PlainFig is developed and maintained by Tejinder, a software developer and independent web builder. We do not invent fictional personas or claim Wall Street pedigrees. What we offer instead is rigorous computational precision: every mathematical formula is documented, every tax bracket is matched against official IRS revenue procedures, and every benchmark cites primary regulatory data from the Federal Reserve and Consumer Financial Protection Bureau (CFPB).
Our Three Core Principles
- Primary Sources Only: We never pull figures from second-hand blogs or unverified summaries. We read the source law: IRS Revenue Procedures, Social Security Administration bulletins, and Federal Reserve releases.
- Full Formula Transparency: Every calculator on PlainFig displays the exact mathematical formula used, step-by-step worked benchmark examples, and clear disclosures of all underlying assumptions.
- Client-Side Privacy: All calculations run entirely inside your browser using vanilla JavaScript. Your income, debt, and loan figures are never sent to a server or tracked.
