What does the GST Calculator calculate?

The GST Calculator estimates tax, taxable amount, or take-home pay depending on the inputs shown on the page.

Is the GST Calculator based on the old regime, the new regime, or both?

Where relevant, the calculator compares the old and new regime assumptions so you can see how deductions and slab choices affect the outcome.

Which inputs affect the tax estimate the most?

Income, deductions, exemptions, age, and regime choice usually matter the most. For salary-oriented pages, bonuses and deductions also change the final number.

Can I rely on the GST Calculator for filing?

No. It is a planning estimate only. Always verify final payroll, lender, or filing numbers against your actual documents and applicable rules.
