Hi Product Hunt! 👋 I built this Advanced Percentage Calculator to make percentage calculations faster, easier, and more accurate for everyone. Most online calculators only solve one type of percentage problem. I wanted to create an all-in-one solution that handles percentage increase, percentage decrease, marks percentage, academic grades (CGPA/SGPA), discounts, profit & loss, tax calculations, and many more—all in one place. The tool is completely free, works on all devices, requires no sign-up, and delivers instant results. This is part of Global Tools Box, where I'm continuously building free online tools for students, professionals, and everyday users. More powerful tools and updates are coming soon. I'd love your feedback and suggestions. Thanks for checking it out and supporting the launch!

Handy little toolkit, the loan calculator gave me an amortization breakdown in seconds without signing up or hitting a paywall.

 Thank you so much, Hacer! I really appreciate the feedback. Keeping it free and accessible without annoying sign-ups or paywalls was my top priority. Glad the amortization breakdown helped! Stay tuned for more tools.

The loan calculator is straightforward and the results came back instantly, which is exactly what I wanted. Nice to have a few useful utilities like this all in one place without needing to sign up.

 Thanks for checking it out, Edanur! I'm glad you found the results quick and straightforward. Providing a clean, all-in-one space for useful utility tools is exactly what I'm aiming for. Thanks for the support!
