About AI How To Invest

Free financial calculators and tools, built by people who believe financial literacy should be accessible to everyone.

Our Mission

AI How To Invest was founded with a simple belief: everyone deserves access to accurate, easy-to-use financial tools without paywalls, hidden fees, or mandatory signups. Financial literacy is the foundation of sound decision-making, yet too many people lack access to the right tools.

We build free, browser-based financial calculators that help people understand mortgages, taxes, retirement planning, insurance, investments, and more. Every tool on our site is designed to be intuitive enough for beginners while providing the depth that experienced users need.

What We Do

We maintain a growing collection of 175+ free online tools across several categories:

Financial Calculators — Mortgage, compound interest, loan amortization, retirement projections, tax brackets, paycheck estimators, and more.
Tax Tools — Federal and state tax calculators updated for the latest tax law changes, including 2026 OBBBA provisions.
Insurance Estimators — Car insurance, life insurance, health insurance, and Medicare cost estimators to help you compare coverage options.
Legal Document Generators — Dispute letters, cease and desist notices, privacy policies, and other legal templates.
Career and Education Tools — Resume builders, cover letter generators, salary comparisons, and GPA calculators.
Developer APIs — Free APIs for currency exchange, IBAN validation, and business day calculations.

Our Values

🔒

Privacy First

Calculator data stays in your browser. We never sell personal information.

✅

Always Free

Every calculator on our site is free to use, with no signup required.

📈

Accuracy Matters

We use official IRS data, Federal Reserve rates, and government sources to ensure accuracy.

👥

Transparency

We clearly label affiliate links and never let partnerships influence our tools or content.

Editorial Standards

We are committed to providing accurate, unbiased, and up-to-date financial information:

Data Sources: Tax rates come from IRS publications, interest rates from Federal Reserve data, and insurance estimates from industry surveys. We cite our sources within each tool.
Regular Updates: Our calculators are updated whenever tax laws change, new legislation passes, or rates shift significantly. Each tool displays its last update date.
No Bias: Our calculators produce results based purely on the math. Affiliate partnerships never influence calculator outputs or recommendations.
Peer Review: We cross-reference our calculator results against established tools (IRS withholding calculator, government benefit estimators) to verify accuracy.

How We Make Money

We believe in full transparency about how we fund this site:

Display Advertising: We show ads through Google AdSense. These ads help fund the development and hosting of our free tools.
Affiliate Links: Some pages contain links to financial products and services. When you click these links and make a purchase or sign up, we may earn a commission at no extra cost to you. These links are always clearly disclosed.
Premium Reports: We offer optional paid PDF reports with personalized financial summaries for users who want a printable analysis.

Importantly, our revenue model never affects our calculator results. The numbers our tools produce are based on mathematical formulas and official data, regardless of any business relationship.
