About SD6Tools
Free online calculators and utilities, built with accuracy and simplicity in mind
Our Mission
SD6 Tools provides free, accurate online calculators and utilities. We believe essential tools like mortgage and retirement calculators, converters and password generators should be accessible to everyone, without accounts or paywalls.
Our Values
Privacy by design
The values you type into our calculators and converters are processed in your browser and are not sent to our servers. Some tools save your scenarios in your browser’s local storage so you can find them later. With your consent, we use Google Analytics 4 and Microsoft Clarity to measure how the site is used; see our privacy policy. Cloudflare Web Analytics also measures page views and site performance in aggregate, without cookies.
Simplicity
Clean interfaces, clear results. We focus on making tools that are intuitive and easy to use, without unnecessary complexity or distractions.
Free & Accessible
No accounts required, no premium tiers, no hidden costs. All our tools are completely free and available in multiple languages.
Accuracy & Quality
Our calculations are thoroughly tested and follow industry-standard formulas. We strive for precision you can trust for important decisions.
