A free app for Android, by Gayatri Softwares.

Developed by Gayatri Softwares, GST Calculator is specifically designed to assist you in everything tax-related.

It makes it easier for you to calculate equations such as GST Tax. You will automatically generate the results for different tax slabs like 5%, 12%, 18% and 28% – and that is for any particular purchase or service that you apply it for.

Even better, this free app allows you to render the results to PDF, and share it via email, whatsApp, and other free messengers.

The interface is simple and user friendly.
