Compare profit margins between two products, departments, or time periods. Calculate gross, operating, and net margins with visual side-by-side analysis.
Margin analysis is most powerful when comparing two scenarios side by side: two products, two time periods, two business units, or before-and-after a pricing change. This calculator computes gross margin, markup, operating margin, and net profit for two data sets simultaneously, with visual bars and a detailed comparison table. That side-by-side view matters because a change that looks small in percentage points can create a meaningful shift in profit dollars when revenue scales are different.
The combined metrics show how the blended margin behaves when both data sets contribute to overall revenue. This is essential for product mix decisions because a high-margin product with low volume may contribute less total profit than a lower-margin high-volume product. Looking at both sets together makes it easier to see whether the business is improving on percentage margin, profit dollars, or both.
Each set shows the full margin waterfall: from revenue through cost of goods, overhead allocation, and taxes to arrive at net profit. The visual comparison makes it easier to see which set is more profitable and where the differences are coming from. It is especially helpful when the reason for the change is not obvious from a single margin figure.
Use this comparison when you want to see whether changes in price, cost, overhead, or tax assumptions are actually improving margin quality between two scenarios. It is a practical way to compare product, period, or policy changes without relying on a single isolated percentage. The side-by-side view makes it easier to tell whether a margin improvement is real enough to matter in dollars, not just in percentage terms.
Gross Margin = (Revenue − Cost) / Revenue × 100 Markup = (Revenue − Cost) / Cost × 100 Operating Margin = (Gross Profit − Overhead) / Revenue × 100 Net Profit = Operating Profit × (1 − Tax Rate)
Result: Set A: 40% margin, Set B: 41.7% margin
Set A has a 40% gross margin ($40K profit on $100K revenue). Set B has a 41.7% margin ($50K on $120K). Set B is both higher margin and higher volume — clearly the stronger product.
Single-scenario margin numbers can look healthy in isolation. The comparison becomes more useful when you line up two products, time periods, or pricing strategies and ask whether the business is actually improving on both percentage margin and total profit contribution.
A higher percentage margin does not automatically mean a better commercial outcome. Low-volume premium items can be outperformed by lower-margin products that generate more total contribution. That is why this kind of calculator is useful for product-mix discussions, not just percentage reporting.
This tool is best for quick management comparison, proposal checks, and before-and-after pricing analysis. If the result will drive a major decision, confirm the overhead allocation method and tax assumptions so the waterfall is not overstating precision.
Margin is profit as a percentage of revenue. Markup is profit as a percentage of cost, so the same deal produces two different percentages depending on which base you choose.
It uses the total revenue and total cost from both sets. Combined gross margin = (Rev1+Rev2−Cost1−Cost2)/(Rev1+Rev2), which weights the larger revenue set more heavily.
Percentage points (pp) — the absolute difference between two percentages. A move from 40% to 42% margin is +2pp, not a 2% relative increase.
Operating margin subtracts overhead costs (SG&A, rent, salaries) from gross profit. It shows profitability after the ongoing cost of running the business, so it should normally be below gross margin.
Both matter. A 60% margin product that only generates $10K profit is less valuable than a 30% margin product generating $100K, so you need both percentage and dollar context.
It depends on industry — SaaS averages 70-80% gross margin, retail 25-50%, manufacturing 20-35%. Compare against your industry benchmark instead of a generic target.
