GST Exclusive to Inclusive Price Converter

When you prepare to sell goods or services in India, GST must be added to your base price to determine what customers pay. This is the most frequently used calculation for sellers, service providers, and invoice-generating teams. Starting with the cost-to-business (exclusive price), you add GST at the applicable rate to get the final invoice amount the customer must pay. For e-commerce platforms, retail shops, consultants, manufacturers, and B2B service providers, this calculator is essential daily software. GST compliance rules mandate that invoices clearly show the exclusive price, GST amount (broken down), and the inclusive total separately. Incorrect calculation can lead to customer disputes, failed tax audits, and penalties from GST authorities. The calculator ensures accuracy across the 0%, 5%, 12%, 18%, and 28% rate slabs, and even handles mixed-rate invoices where different items have different GST rates.
