How do you calculate project margin?

Subtract cost from sell price to get gross margin dollars, then divide by the reference revenue. With a sell price of $125 and cost of $100, gross margin is $25; over a $100 reference that is a 25% margin.

What is a good project margin for district energy work?

It varies by scope and risk. Civil-heavy pipe-laying often carries lower margins than packaged plant or controls work. The 25% in the example is a solid gross margin for equipment-led scope; long civil jobs frequently run lower.

What is the difference between margin and markup?

Markup divides margin dollars by cost; margin divides by revenue. The same $25 on $100 of cost is a 25% markup but a 20% margin on $125 of revenue. This tool uses the revenue-based reference, giving 25% against a $100 reference.

Why is there a separate reference revenue input?

It lets you express margin against a base other than the sell price, for example a funded grant value or a normalized contract figure, which is common in publicly funded district energy schemes.

Does this include overhead?

No. The required cost should be your direct delivery cost. Project margin here is a gross figure; subtract overhead and financing separately to reach net margin.

How do I use margin to compare two heat-network bids?

Percent margin normalizes for size, so a small substation upgrade and a large network extension can be ranked side by side. Pair the percent with the absolute gross margin dollars so you do not chase a high percentage on a tiny job.

District Energy & Thermal Network Equipment calculator

Project Margin Calculator

Project margin is the share of a district energy project's revenue that survives after the cost of delivering it, expressed as a percentage. Estimators, project managers and commercial leads use it to compare heat-network jobs of different sizes on a common footing and to decide which bids are worth chasing. This calculator takes the sell price or funded revenue, the required cost to deliver, and a reference revenue base, then returns both the gross margin in dollars and the margin percent. Because district energy projects span long schedules and volatile material and labor costs, watching margin against the bid number is how you catch a job slipping before it loses money.

What this calculator does

Calculate margin for a district heating, district cooling, central plant, thermal storage, or distribution network project on a consistent scope and revenue basis.
Use it when project margin in district energy and thermal network equipment needs a clean margin number for a district energy and thermal network equipment go / no-go review.
It computes gross margin dollars (sell price minus cost) and divides by a reference revenue to express margin as a percentage.

Formula used

Project gross margin dollars = project sell price or funded revenue - required project cost
Project margin = project gross margin dollars ÷ reference project revenue

Inputs explained

Project sell price or funded revenue:
Required project cost:
Reference project revenue:

How to use the result

Use it at bid time to screen opportunities and during delivery to track whether the as-built cost is eroding the margin you priced.
It is a gross-margin view: it ignores overhead, financing and the time value of money over a multi-year network build, so a healthy gross margin can still leave a thin net result.

Current U.S. benchmarks

Industrial electricity averages 8.66 cents per kWh across the U.S. (EIA, Apr 2026), up 5.5% from a year earlier. Energy-intensive steps carry this directly into unit cost.
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).
