Retention Money

Retention money is the percentage of each payment under a government contract that the client withholds as security against defective work, non-performance, or latent defects that may appear during the Defect Liability Period (DLP). The terms "retention money" and "Security Deposit" are used interchangeably in Indian government procurement, though some contracts draw a technical distinction between the two.

What is Retention Money in government procurement?

In most Indian government works contracts, retention money is deducted from each Running Account (RA) Bill or Interim Payment Certificate (IPC) at a prescribed rate, typically 5 to 10 percent for the first half of the contract period, reducing to a lower rate thereafter, or a flat 2.5-5 percent throughout. The accumulated retention provides a financial reserve that the government can use to:

• Rectify defects if the contractor fails to do so during the DLP.
• Recover costs from completion by another agency if the contractor abandons the contract.
• Set off any amounts owed by the contractor for liquidated damages, indemnities, or other liabilities.

In FIDIC-based contracts (used by NHAI and some World Bank-funded projects), retention is commonly split: the first half is released on completion of works (after issuance of the Taking-Over Certificate), and the second half after expiry of the Defect Notification Period. This split-release structure is more contractor-friendly than the Indian government standard contracts, which typically hold all retention until after DLP.

The maximum retention cap is important: once cumulative retention reaches the cap (often 5-10 percent of contract value), no further deductions are made. The contractor receives full payment on subsequent bills until final closure.

Some contracts allow the contractor to replace cash retention with a Retention Money Guarantee (a bank guarantee in lieu of withheld cash). This preserves the contractor's working capital, RA Bills are paid in full against the BG, but requires available bank guarantee limits.

Why it matters for bidders

Retention money is effectively interest-free working capital extended by the contractor to the government for the duration of the contract and DLP. On a Rs 50 crore contract with 5 percent retention held over a 24-month construction period and 12-month DLP, Rs 2.5 crore is tied up for three years. At a cost of capital of 12 percent per annum, this represents Rs 90 lakh in financing cost that is often not explicitly priced into BOQ overheads.

Contractors bidding on long-duration contracts (infrastructure projects with 3-5 year execution periods and 2-year DLPs) should model retention money cash flows in their project cost models and price the financing cost in their overhead margin. Projects where the government is known for slow retention release (post-DLP, waiting for audit clearance) carry additional cost risk.

The Retention Money Guarantee option, where available, substantially improves project cash flows and should be exercised when bank guarantee limits are available.

Example

A contractor wins a Rs 30 crore bridge construction contract with 5 percent retention deducted from each RA Bill until a cap of Rs 1.5 crore (5 percent of contract value) is reached. The bridge takes 30 months to complete. After physical completion and issuance of the completion certificate, the DLP of 24 months begins. At the 54th month (30 months construction + 24 months DLP), the contractor applies for retention release, confirming no outstanding defects or claims. The Rs 1.5 crore retention is released within 30 days.

Key rules / thresholds

• Typical retention rate: 2.5-5 percent of each RA Bill.
• Maximum retention cap: 5-10 percent of contract value.
• First half of retention may be released on practical completion in FIDIC-based contracts; Indian standard contracts typically release all retention after DLP.
• Retention Money Guarantee (BG in lieu of cash retention) is available in some contracts.
• The DLP during which retention is held: 12 months for buildings, 24-60 months for roads and highways, 5-7 years for bridges and major structures.
