About AllYouTools
AllYouTools is a free collection of online calculators and converters built with one simple goal: to give everyone fast, accurate answers to everyday questions without sign-ups, downloads, or hidden costs. Whether you are estimating a loan EMI, planning a monthly SIP investment, checking your BMI, or counting words in an essay, our tools are designed to get you the result you need in seconds.
Our Mission
Financial and everyday calculations should not require spreadsheets, complicated apps, or expertise in formulas. We believe useful tools should be simple, transparent, and accessible on any device. Every calculator on AllYouTools explains the formula it uses, shows worked examples, and answers the most common questions people have about the topic — so you not only get a number, you understand where it came from.
What Makes AllYouTools Different
- 100% free, forever. Every tool is free to use with no accounts, subscriptions, or usage limits.
- Privacy first. All calculations run directly in your browser. The numbers you enter — loan amounts, dates of birth, body measurements, or text — are never sent to or stored on our servers.
- Educational content. Each tool page includes a plain-language explanation of the underlying formula, practical examples, and a detailed FAQ section.
- Mobile-friendly and fast. The site is built to load quickly and work smoothly on phones, tablets, and desktops.
Our Tools
AllYouTools currently offers ten tools across three categories: finance calculators (EMI, SIP, compound interest, and GST), everyday utilities (age, BMI, percentage, and unit conversion), and text tools (word counter and password generator). We review our formulas regularly and continue to add new tools based on what visitors ask for.
Accuracy and Responsibility
We take accuracy seriously and test each calculator against standard formulas and known reference values. That said, our tools are intended for general information and educational purposes. Results — especially financial ones — should be treated as estimates, and important decisions should always be confirmed with a qualified professional. You can read more in our disclaimer.
