How do you calculate project gross margin?

Subtract total project cost from total project revenue to get the dollar margin, then divide by the reference amount and multiply by 100. With $185,000 revenue and $148,000 cost the dollar margin is $37,000, which is 20% of the $185,000 reference.

What is a good gross margin on a hospital equipment project?

It varies by product and channel, but built-to-spec clinical furniture and equipment projects commonly target 20-35% gross margin. The 20% in the worked example is a workable but lean result that leaves little room for cost overrun.

What is the reference amount for and why isn't it always revenue?

The reference amount is the base you divide by to get the percentage. Using revenue ($185,000) gives a conventional margin-on-sales figure; some teams use cost instead to express markup. Keep it consistent so quotes compare cleanly.

Gross margin vs. markup — what's the difference?

Gross margin divides the $37,000 profit by revenue ($185,000) for 20%. Markup would divide the same $37,000 by cost ($148,000) for about 25%. Same dollars, different denominator — confusing them is a frequent quoting error.

Why does dollar margin matter when I already have a percent?

A high percentage on a tiny job can earn fewer real dollars than a lean percentage on a large one. The $37,000 dollar margin tells you the actual profit the project contributes regardless of the rate.

How do I protect this margin on a long-lead medical contract?

Make sure the cost input is fully loaded — freight, installation, compliance and rework — and build escalation clauses for material moves. A 20% margin can vanish if even a few percent of unbudgeted cost slips into the job.

Hospital Equipment & Clinical Furniture calculator

Project Margin Calculator

The Project Margin calculator turns a hospital-equipment contract's revenue and fully-loaded cost into both a dollar margin and a percentage margin against a reference amount. Whether you are bidding a fleet of patient-room casework, a build-to-spec stretcher order, or a clinical furniture fit-out for a new hospital wing, this is the number estimators and program managers defend in the quote review. It separates the absolute profit dollars from the margin rate so finance and sales can both read the deal. On long-lead medical projects with material and compliance costs that move, a clear margin figure is what keeps a job from quietly going underwater.

What this calculator does

Calculate the gross margin percentage on a hospital equipment project or multi-unit contract by comparing total project revenue to total estimated project cost.
Use it when reviewing the margin on a large hospital equipment project such as a full-facility bed package, a multi-year service contract, or a GPO contract after final cost estimation.
It computes the dollar margin (revenue minus cost) and the gross margin percentage of that dollar margin against a chosen reference amount.

Formula used

Project dollar margin = total project revenue - total estimated project cost
Project margin = dollar margin ÷ reference amount × 100

Inputs explained

Total project revenue or contract value:
Total estimated project cost:
Reference amount for project margin calculation:

How to use the result

Use it when quoting, reviewing, or closing out a fixed-scope hospital equipment or clinical furniture project.
Margin quality depends entirely on cost completeness — if installation, compliance documentation, freight or rework are missing from the cost input, the percentage overstates real profit.

Current U.S. benchmarks

The producer price index for lumber and wood products stands at 280.994 (BLS, May 2026), up 4.2% from a year earlier. Quotes priced off last quarter's material cost miss this move.
U.S. manufacturing runs at 75.6% of capacity with new factory orders at $657B per month (Federal Reserve and Census, May 2026).
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).
The U.S. has 14,378 furniture and related products establishments employing about 355,594 workers (Census County Business Patterns, 2023).
