Free online tools for India — GST Calculator (inclusive/exclusive, CGST/SGST/IGST) and SIP Calculator (mutual fund returns with compounding). Fast, private, no login required. Hindi & Marathi supported.

How Fibha Works

Fibha is designed around a simple principle: your data stays on your device. Every calculation — whether it is GST arithmetic or SIP projections — runs entirely inside your browser. Nothing is uploaded, nothing is stored on a remote server, and nothing requires an account. Open the tool, enter your numbers, and get an instant result you can trust.

GST Calculator

Add or remove GST for any amount. Supports all current slab rates (0%, 5%, 18%, 40%) and special rates (0.25%, 3%, 28%). Handles both intra-state (CGST + SGST) and inter-state (IGST) transactions. Updated for the post-22 Sep 2025 rate rationalisation.

The Goods and Services Tax is a destination-based, multi-stage consumption tax that replaced a patchwork of indirect levies — Central Excise, Service Tax, VAT, Entry Tax, and several cesses. Introduced on 1 July 2017, it unified India into a single common market.

A Systematic Investment Plan is an arrangement where a fixed amount is automatically debited from your bank account at a regular interval and invested into a mutual fund scheme of your choice. Over time, rupee cost averaging smooths out the volatility of equity markets.
