How to Calculate Markup for Tender Bids

Markup covers profit, contingency, risk allowances, and general overheads. Setting the right markup is critical to winning work while staying profitable.

Two Ways to Express Markup

Markup can be expressed in two ways:

1. Markup on Cost (On-Cost)

Formula: Bid Price (before GST) = Cost × (1 + Markup%)

Example: If your total cost is ₹1,00,000 and you add 15% markup on cost:

• Subtotal = 1,00,000 × (1 + 0.15) = ₹1,15,000

Use when you want profit as a percentage of your cost.

2. Markup on Bid Price (Off-Top)

Formula: Bid Price (before GST) = Cost ÷ (1 − Markup%)

Example: If your cost is ₹1,00,000 and you want 15% profit as a share of the bid price (off-top):

• Subtotal = 1,00,000 ÷ (1 − 0.15) = ₹1,17,647

Use when the contract specifies profit or margin as a percentage of the bid value. Common in some BOQ formats.

Use our Bid Price Calculator to compute both—switch between “On cost” and “Off-top” in the calculator.

16 Factors Affecting Mark-Up

Research on Indian construction contractors identifies these factors that influence markup decisions:

Factor	What to consider
Competition	Number of competitors and intensity of rivalry
Project size & cost	Larger projects often allow different margin structures
Project type	Buildings vs infrastructure vs services
Duration	Longer projects may need higher contingency
Location	Remote or difficult locations increase risk and cost
Season	Work done in monsoon or extreme heat affects productivity
Hazard & difficulty	Complexity, site conditions, technical challenges
Owner/consultant reputation	Payment history, dispute record, design quality
Time for bid preparation	Less time means higher risk and often higher markup
Labour availability & productivity	Local labour rates and output norms
Material availability & costs	Supply chain reliability, price volatility
Subcontracting	% of work subcontracted and sub-bids received
Insurance & fringe benefits	Policy costs, statutory benefits
Supervisory talent	Availability of experienced staff
Construction method	Most economical way to execute the work
Uncertainty & historic profit	Accuracy of estimate, past margins
Economic conditions	Current and forecasted demand, inflation
Risk attitude	Your appetite for risk vs guaranteed work

Indian Bidding & Estimation Practices

Surveys of Indian contractors reveal:

How contractors estimate cost

• 82% use first-principle estimation (material + labour + plant from bottom up)
• 18% refer to a standard schedule of rates (SOR)

Use of statistical/mathematical tools

• 55% use such tools for cost estimation and judging chances of winning a bid

Dealing with uncertainties

• 68% apply a correction factor to their estimate
• 18% adjust the markup instead

Mark-up distribution

• 43% distribute markup evenly across all items
• 5% front-load markup (higher margins in early items)
• 33% distribute unevenly across different items
• 19% do not follow a fixed policy

Labour and plant cost estimation

• Labour costs: mainly from prevailing rates near the site and productivity norms published by research bodies; rule of thumb and past experience also used
• Plant costs: 58% use depreciating cost; 42% use fixed hire charges

Typical markup range

Markup typically varies between 1% and 20% of total cost, depending on sector, competition, and risk. Civil and construction often sit in the 12–20% range; IT and consultancy may go 15–25%.

How to Choose Your Markup

1. Start with your sector norm—see our sector pages for typical ranges.
2. Review the 16 factors—adjust up for higher risk, competition, or uncertainty.
3. Decide on-cost vs off-top—match the tender format and how profit is expressed.
4. Test different scenarios—use the Bid Price Calculator with GST and TDS to see net receivable.
