What we make
Codaphic Toolkit is a collection of free utilities: numbers to words, percentages, loan EMI, tips, BMI, compound interest, and more. Each tool is designed for clear answers and readable explanations so you can learn the formula, not only the result.
Who it is for
Students, freelancers, and anyone who needs a quick, trustworthy calculation without opening a spreadsheet. The site is part of the Codaphic family of products.
How calculations work
Math runs locally in JavaScript on your device. We do not require sign-in. A lightweight anonymous visitor counter helps us understand traffic; see the Privacy Policy for details.
Accuracy
Tools are provided for education and everyday estimates. Loan, tip, and health-related calculators are not financial, legal, or medical advice. Always confirm important figures with a professional or official source.
