India's free GST calculator, built for the people who use GST every day
GSTFlix is a free, no-signup GST calculator and compliance toolkit built for Indian businesses, chartered accountants, freelancers, and e-commerce sellers who need fast, accurate GST numbers without wading through paid software.
Why we built GSTFlix
Most free GST calculators online are lead magnets — a single input box designed to funnel you toward a paid accounting subscription. We thought Indian taxpayers deserved better: a genuinely complete toolkit covering standard GST, reverse GST, multi-item invoices, Input Tax Credit estimation, composition scheme rates, penalty calculation, invoice generation, and HSN/SAC lookup — all in one place, all free, with no account required.
What makes GSTFlix different
Twelve calculation modes
From a simple standard GST split to breakeven pricing and EMI-with-GST, GSTFlix covers scenarios other calculators skip entirely.
Nothing leaves your device
Every calculation, saved invoice, and history entry lives in your browser's local storage. We never see your numbers, and there is no server-side database.
Updated for GST 2.0
Following the 56th GST Council meeting, GSTFlix reflects the simplified 0%, 5%, 18%, 40% slab structure effective September 2025.
Built for real workflows
Invoice generation, HSN/SAC lookup, GSTIN validation, and filing deadline countdowns sit alongside the calculators so you rarely need to leave the page.
Who uses GSTFlix
GSTFlix is used daily by chartered accountants checking quick figures between client calls, small business owners pricing products, freelancers invoicing international clients, e-commerce sellers reconciling TCS deductions, and finance students learning how CGST, SGST, and IGST actually work.

A note on accuracy
GST rates, thresholds, and rules change periodically through GST Council meetings and CBIC notifications. We update GSTFlix's rate tables promptly after each change, but GSTFlix is a calculation aid, not a substitute for professional advice — always confirm figures relevant to a filing or legal decision with a qualified Chartered Accountant or the official GST portal. See our full disclaimer for details.
