What is the difference between markup and margin?

The base they are measured against. Markup is a percentage of cost: add 11.1% to a $10.8M cost and you get a $12.0M price, a $1.2M addition. Margin is that same $1.2M expressed as a percentage of the price, which is 10%. The dollars are identical; only the denominator changes. The confusion is expensive because the two numbers are always different and always in the same direction, markup is the larger figure, so a contractor who marks work up 10% and believes they are making a 10% margin is actually making only about 9%. Pricing is done in markup because you build a price up from cost; profitability is measured in margin because you judge it against the revenue earned.

What is a fee on a cost-plus or GMP contract?

On a cost-plus or guaranteed-maximum-price contract the fee is the contractor’s profit, stated separately from the reimbursed cost of the work. Instead of a single lump-sum price with the profit hidden inside, the owner agrees to pay the actual cost of the work plus a defined fee, which may be a fixed dollar amount or a percentage. On a GMP the fee sits on top of the cost up to the guaranteed maximum, and savings below the maximum are often shared. Because the owner reimburses cost directly, the contract has to define carefully what is a reimbursable cost, what is general conditions, and what must come out of the fee, which is exactly where the direct-versus-indirect line becomes a dollars question.

What erodes margin during a project?

Any dollar of cost that lands above the budget the price was built on. The price is fixed at the contract value; profit is simply whatever is left after the job is actually built. On our example the $12.0M price was set over a $10.8M cost budget, a planned $1.2M margin. If the work is forecast to finish at $11.1M instead, through an overrun, a delay running up indirect cost, or a change the owner will not pay for, the margin compresses to $0.9M, from 10% to 7.5%, without the price moving at all. This is why watching the forecast cost at completion against the contract value, not just actual cost against budget, is the real-time read on whether the margin is holding.

Margin, Fee& Markup

The same profit, read three ways. Confuse markup for margin and you quietly overstate what the job makes.

Definition

Markup is the percentage a contractor adds to cost to reach the price. Margin is the resulting profit expressed as a share of that price. They describe the same dollars from opposite ends, so an 11% markup on cost is only a 10% margin on price. Fee is the agreed profit on a cost-plus or guaranteed-maximum-price contract, where cost and profit are stated separately.

From cost to price, and what eats it

The price is built by adding $1.2M of markup to the $10.8M cost, an 11.1% markup that is a 10% margin on the $12.0M price. Let the cost drift to an $11.1M forecast and the price cannot follow: the margin is what gives.

Markup, margin, fee

Three words for how profit is added, measured, and agreed. They are easy to use interchangeably and expensive to confuse.

Term	What it is	On our example
Markup	Profit as a percentage of cost	$1.2M ÷ $10.8M = 11.1%
Margin	Profit as a percentage of price	$1.2M ÷ $12.0M = 10%
Fee	Agreed profit on a cost-plus / GMP job	Stated separately from reimbursed cost

The cost the markup is built on splits into direct and indirect; the forecast that erodes margin is the estimate at completion.

How POD makes margin visible

POD holds the client contract value as the revenue of record, the original contract plus the approved client change orders, and it reads the committed and actual costs beneath it and forecasts the final cost through earned value. Because those two sides, price and projected cost, already live in POD, the margin between them is visible from figures it already holds, and it moves as costs land and change orders are approved rather than waiting for a close. POD does not set your fee, mark the work up for you, or guarantee the margin; it surfaces the gap from the numbers you give it so an erosion shows up while there is still room to respond.

Frequently asked questions

Margin holds only if the forecast does

The price is fixed the day the contract is signed. Whether the margin survives is decided by the cost still to come.
