How do you calculate project margin?

Subtract delivered cost from revenue to get the gap, then divide by the revenue basis. With revenue of 125, cost of 100, and a basis of 100, the gap of 25 over 100 gives a 25% margin.

What is a good project margin for port equipment work?

It varies by scope: commodity fabrication may run 8-15%, while engineered retrofits and integration with schedule risk often target 20-30% to cover contingency. The 25% in the example sits in healthy engineered-project territory.

What is the difference between margin and markup?

Margin divides profit by revenue, while markup divides profit by cost. A 25% margin on 125 of revenue is the same job as a 25% markup on 100 of cost, so quoting the two interchangeably underprices the work.

Project margin vs. gross margin, are they the same?

Gross margin usually means the company-wide ratio of revenue less cost of goods over revenue. Project margin applies the same math to a single job so you can compare individual contracts, which is what estimators need.

Why divide by a separate revenue basis instead of revenue?

The basis lets you measure margin against list price, contract value, or a normalized figure. Setting the basis equal to revenue gives the standard margin; using a different basis lets you compare against a target or reference amount.

How can I improve margin on a terminal equipment project?

Tighten the estimate on marine logistics and access, price change orders promptly, add contingency for liquidated damages, and reduce rework and recoating scope that quietly erodes delivered cost.

Port, Crane & Terminal Equipment calculator

Project Margin Calculator

Project margin is the percentage of a job's revenue left after delivered cost, and it is the number that tells a crane fabricator, terminal maintenance contractor, or equipment integrator whether a project actually made money. On port and terminal work, margin is squeezed by long lead times, marine logistics, liquidated-damages risk, and change orders, so estimators and project managers track it from bid through closeout. This calculator takes the revenue received, the delivered cost, and the revenue basis you want to measure against, then returns margin as a clean percentage. It is the go-to check when comparing a completed retrofit against its bid or deciding whether the next tender is worth chasing.

What this calculator does

Estimate project margin for port, crane and terminal equipment using production-ready inputs so teams can measure the gap between available and required amounts.
Use it when project margin in port, crane and terminal equipment needs a clean margin number for a port, crane and terminal equipment go / no-go review.
It computes project margin as the gap between revenue and cost divided by a chosen revenue basis, expressed as a percentage.

Formula used

Project margin amount gap = available project margin amount - required project margin amount
Project margin = amount gap ÷ reference project margin amount

Inputs explained

Contract Price / Revenue Received:
Delivered Project Cost:
Revenue Basis for Margin:

How to use the result

Use it at bid time to test pricing and at closeout to measure realized profitability on a crane or terminal equipment project.
It is a single-point margin snapshot and does not account for cash-flow timing, retention, or the cost of capital tied up over a long marine project.

Current U.S. benchmarks

U.S. housing starts run at 1,177k per year (Census, May 2026), down 8.7% from a year earlier, the demand driver for building products.
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
