About FinKit

Smart financial tools, built for everyone.

Why FinKit Exists

Most financial calculators online are cluttered with ads, require signups, or try to sell you something. FinKit is different — every calculation happens right in your browser. No data is ever sent anywhere. No accounts. No tracking. Just tools that work.

How It Works

All calculators run entirely in your browser using JavaScript. Your numbers never leave your device. We don't use cookies, we don't collect analytics, and we don't store any of your financial data.

Our Tools

FinKit offers a growing collection of financial calculators and planners:

Financial Education & Content

Beyond calculators, FinKit publishes in-depth articles and guides on personal finance, investing, and financial planning. Each article pairs with our tools so you can apply what you learn immediately. From compound interest deep dives to FIRE strategy breakdowns — our content helps you understand the "why" behind the numbers.
