How do you calculate formula margin per gallon?

Divide gross margin per gallon by selling price per gallon and multiply by 100. With $9 gross margin on a $30 gallon, that is 9 / 30 x 100 = 30% formula margin.

What is a good formula margin for coatings and resins?

Commodity architectural paints often run 25-35% gross margin, while specialty and performance resins target 40%+. In the worked example, 30% is a mid-band result sitting 5 points under a 35% target.

What does the gap to target mean?

It is target margin rate minus actual formula margin, in percentage points. A 35% target against a 30% actual gives a 5-point gap, meaning price or cost must move to close it.

Formula margin vs markup — what's the difference?

Margin is gross profit as a share of selling price; markup is gross profit as a share of cost. A $9 profit on a $30 price is 30% margin but 43% markup ($9 / $21 cost), so never quote the two interchangeably.

How much do I raise price to hit target margin?

To lift a 30% margin to 35% while holding a $21 cost, price must rise to $21 / (1 - 0.35) = about $32.31, roughly a $2.31 per gallon increase.

Does formula margin include overhead and freight?

Only if you built them into gross margin per gallon. If your $9 figure is material-only contribution, the true bottom-line margin is lower once plant burden and outbound freight are loaded.

Paint, Resin & Polymer Compounding calculator

Formula margin Calculator

Formula margin is the percentage of a compounded product's selling price that survives after raw material and direct conversion cost — the number a coatings or resin business actually lives on. Formulators, cost engineers, and commercial managers use it to decide whether a paint or polymer formula clears the profitability bar before it goes on a price list. Because pigment, resin, and additive costs swing with feedstock markets, a formula that penciled at 32% last quarter can quietly slide below target. This calculator turns dollars-per-gallon into a clean margin rate and shows exactly how many points you are above or below your goal.

What this calculator does

Calculate the gross margin percentage of a paint or resin formula from margin per gallon and selling price, and compare it against your target.
you need a clean margin percentage on a formulation to defend pricing or flag formulas that fall below target
It converts gross margin and selling price per gallon into a formula margin percentage and reports the point gap to your target margin rate.

Formula used

Formula margin rate = gross margin per gallon / selling price per gallon * 100
Gap to target = target margin rate - formula margin rate

Inputs explained

Gross margin per gallon:
Selling price per gallon:
Target margin rate:

How to use the result

Use it during formula costing, annual price-list reviews, or whenever a raw material cost change makes you re-check whether a SKU still earns its target margin.
It uses a single gross-margin figure you supply, so it is only as accurate as your cost build-up — it will not catch under-absorbed overhead, freight, or waste allowances left out of that number.

Current U.S. benchmarks

The producer price index for plastic resins and materials stands at 319.371 (BLS, May 2026), up 19.5% from a year earlier. Quotes priced off last quarter's material cost miss this move.
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.
The producer price index for industrial chemicals stands at 344.336 (BLS, May 2026), up 16.1% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 14,543 chemical manufacturing establishments employing about 911,245 workers (Census County Business Patterns, 2023).
