Find L1 and compare rates
🎯 My rate: how much is X% below or above?
EMD (bid security) and performance security
Common rules (GFR, central govt): EMD 2–5% for goods; performance security 3–5% for goods and services, 3–10% for works. Always follow the % written in your tender notice (NIT).
GST and TDS on a government bill
Works contracts: GST 18% (from 22 Sep 2025 the 12% rate was removed). Government deducts GST-TDS 2% when the contract value (without GST) is more than ₹2.5 lakh, and income-tax TDS u/s 194C: 1% (individual/HUF), 2% (others). Check with your CA.

Questions
How is L1 found?
Type each bidder's amount. The tool puts them from lowest to highest – the lowest is L1. It also shows how much each one is above or below the estimated cost and the L1 rate.
How much EMD do I pay?
EMD (bid security) is written in the tender notice, usually 2% of the estimated cost. Registered MSEs and startups often get exemption and give a Bid Security Declaration instead.
How much will I get in my bank from a government bill?
Bill + GST, minus GST-TDS 2% (when the contract is above ₹2.5 lakh) and income-tax TDS 1% or 2%. The TDS amounts show in your GST and income tax records and can be adjusted.
