About FinKit

Free 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:

Compound Interest Calculator — Forward & reverse modes
FIRE Planner — Financial Independence planning (coming soon)
Product Comparator — Compare investment products (coming soon)
Portfolio Optimizer — Optimal asset allocation (coming soon)
And more on the way...
