GST math, in one tap.

Add GST to a base price, or work backwards from an inclusive price to see the tax inside it — across all four slabs, with the CGST/SGST split shown.

How GST is calculated

Adding GST: tax = base price × rate ÷ 100. Removing it from an inclusive price: base = price × 100 ÷ (100 + rate). Within a state the tax splits equally into CGST and SGST; across states it's charged as a single IGST at the same rate.

The main slabs are 5% (essentials), 12% and 18% (most goods and services — loan processing fees fall here), and 28% (luxury items). Financial services, including a lender's processing fee and prepayment charges, attract 18% GST.

GST and your loan

Loan EMIs themselves carry no GST — interest is exempt. But the fees around a loan do: processing fees, foreclosure charges, bounce charges and documentation fees all attract 18%. A "2% processing fee" on a ₹5 Lakh loan is really ₹10,000 + ₹1,800 GST = ₹11,800.

When you compare loan offers on Samridhya, check each lender's fee schedule with GST included — two offers with the same rate can differ by thousands in fees.

Common questions.

How do I remove GST from a price?+

Divide the inclusive price by (100 + rate) and multiply by 100. For example, ₹11,800 at 18% GST → ₹11,800 × 100 ÷ 118 = ₹10,000 base.

Is there GST on loan EMIs?+

No — interest on loans is exempt from GST. But processing fees, foreclosure and bounce charges attract 18% GST.

What are the GST slabs in India?+

5%, 12%, 18% and 28%, plus exempt and zero-rated categories. Most services, including financial-service fees, fall in the 18% slab.

What is the difference between CGST, SGST and IGST?+

Within a state, GST splits equally into central (CGST) and state (SGST) halves. Interstate supplies are charged as a single integrated tax (IGST) at the same total rate.
