Change order price

$3,250.00

About this tool

Change order price = direct cost × (1 + markup) — $2,500 × 1.30 = $3,250.

How to use

Enter the extra work's direct cost and your markup — price, profit, and achieved margin solve live.

How the math works

Achieved margin = profit ÷ price — a 30% markup yields a 23.1% margin, not 30%.

Change orders usually carry higher markup than base bids: mobilization, disruption, and paperwork cost real money.

Check the achieved margin against your target before sending — never price extras at cost.

Formula

CO price = cost × (1 + markup)

Common questions

▸How do you price a change order?

Change order price = direct cost x (1 + markup). Enter the extra work's cost and your markup - the tool solves price, profit, and achieved margin live so extras never get priced at cost.

▸How do you calculate markup in construction?

Markup = (price - cost) / cost, applied as price = cost x (1 + markup). A $2,500 change order at 30% markup prices at $3,250.

▸What's the difference between 30% markup and 30% margin?

30% markup on $2,500 gives a $3,250 price, but the margin is $750 / $3,250 = 23.1%. Markup is measured on cost; margin is measured on price - the tool shows both.

▸What markup should a contractor charge on change orders?

Higher than the base bid - typically 30-50%. Extras disrupt the schedule, need remobilization, and carry extra paperwork, so margin protection matters more on change orders.

▸Should change orders have higher markup than the original bid?

Yes. Mobilization, schedule disruption, and admin cost real money on extras. Check the achieved margin against your target before sending - never price extras at cost.
