Guides: Money, Tax, Health & Everyday Tools
Practical, step-by-step guides that explain the rules behind everyday money and health decisions in India, with real worked examples. Each guide links to a free MavexTech calculator or tool, so you can run your own numbers in seconds.
Our guides are written for FY 2025-26 rules and checked against official sources such as the Income Tax Department, EPFO, PFRDA and the GST portal. Every example is calculated, not guessed, and each guide notes where rates change so you know what to double-check.
