GST Calculator

Purpose-built GST calculator that supports common tax regimes and currency contexts. It computes GST payable, net price, and total amount from a base price, accommodating both inclusive and exclusive pricing models. It is suitable for accountants, bookkeepers, freelancers, and sales staff who prepare invoices or quotes. The tool handles India-like CGST/SGST and IGST splits for intra- and inter-state scenarios, plus a flat 10% GST for Australia. Conceptually, it applies standard tax formulas to derive tax components and final totals, then formats results for invoicing and reconciliation. Unique value lies in jurisdiction-aware outputs, clear breakdowns, and ready-to-export figures for compliance and reporting. Core features include input validation, two-decimal formatting, and optional tax breakdown fields that appear when applicable. Typical use cases include calculating GST on a product price, estimating invoice totals for quotes, and reconciling tax obligations during bookkeeping or tax return preparation.
