Free online tools that respect your privacy. No sign-up. No tracking. No nonsense.
Inisyght Tools builds free online calculators and converters that help people make better financial decisions. Every tool runs entirely in your browser — your data never touches a server.
We started with a Debt Snowball & Avalanche Calculator after realizing most free tools online require sign-up, look outdated, or only show one strategy at a time. We built the tool we wished existed: clean, fast, private, and genuinely useful.
Compare both payoff strategies side by side using your actual numbers. Enter your debts once and see total interest, payoff timeline, and monthly schedule for Snowball, Avalanche, and Minimum-Only scenarios. Built with Chart.js for visual payoff tracking.

Every free tool we found online had a catch: sign-up required, data uploaded to servers, cluttered with ads, or just plain ugly. We believe useful tools shouldn't come with strings attached.
Inisyght Tools is built on a simple philosophy: tools should be free, private, and well-designed.
Zero data leaves your browser. No accounts, no tracking, no cookies for analytics.
Every tool works immediately. Open the page and start. No email, no password, no spam.
Tools should be easy to look at and easy to use. No clutter, no confusion.
No premium tiers. No "upgrade to unlock." All features are available to everyone.
Beyond tools, we publish guides and articles to help you understand debt payoff strategies, personal finance, and how to get the most out of our tools. All content is written with one goal: helping you become debt-free faster.
