Getting gross profit vs net profit wrong doesn’t just cloud your reporting—it breaks your story, and can derail fundraising.
Confusing them muddies your story, weakens your metrics, and blurs how the business makes money. Investors and teams read different signals from each number. If you don’t separate them, you can’t price right, align spend to strategy, or prove operating leverage. Get them right and you make better decisions, build trust fast, and scale with confidence.
In this post, you’ll get clear definitions and formulas. We’ll show common mistakes and how to set up these metrics in Runway. Then we’ll walk through scenario planning and headcount examples so you can start forecasting better today.

Why clarifying the difference matters
Mixing up gross profit and net profit can impact every decision you make. It’s not just another P&L line.
Let’s talk forecasting. Gross profit margins show how efficiently you deliver products or services. Net profit tells you if your business model truly works, once you count every cost. Swap them or calculate them wrong, and your growth projections fall apart.
Smart expense management starts here. Cut COGS, and it could look like you’re improving profits, but it might actually point to bigger margin problems. Accurate profit numbers guide your headcount plans and hiring, too. Teams need to know what costs tie right to your product and which affect the bigger business picture.
Defining gross profit and net profit
Gross profit measures your core business performance. It’s what’s left after you pay the direct costs to make or deliver what you sell.
Net profit goes deeper. It captures your true bottom line after every cost, including operating expenses, interest, taxes, and one-off charges.
Here are the standard formulas:
- Gross profit = revenue – cost of goods sold (COGS)
- Net profit = gross profit – operating expenses – interest – taxes
Gross profit: formula and key components
The core formula’s simple: revenue minus COGS gives you gross profit. But getting COGS right takes some care.
For product companies, COGS covers raw materials, direct labor, and overhead tied to producing goods. Service businesses need “cost of services”: direct labor, project-specific materials, and the software you use to deliver your service.
Things get interesting with hybrid models. If you sell IoT devices and subscriptions, you’ll count manufacturing, select labor, and supporting software or server costs in COGS.
Misclassifying expenses creates real issues. Maybe you treat sales commissions as COGS (when they’re operating), mix up shipping, or even lump admin rent with production costs. That throws off your results.
Net profit: formula and factors to consider
Start with gross profit. Subtract operating expenses, interest, taxes, and any non-operating items. That’s net profit.
Operating expenses mean all selling, general, and administrative costs — marketing, leadership salaries, the works. Interest tracks debt payments. Tax calculations vary by where and how you’re structured.
Don’t forget non-operating items. They can shift net profit in a big way: asset sales, investment income, restructuring charges, or currency changes all count. Big non-operating gains boost profitability ratios — heavy losses pull down even strong-performing businesses.
Common pitfalls and misinterpretations
Confusing COGS and operating costs is a top mistake. The problem gets worse if you allocate overhead wrong — say, by including general admin as COGS, or not splitting shared costs.
Inventory errors also hit COGS. If you overstate ending inventory, COGS looks lower. That inflates gross and net profit. Understating inventory flips the picture.
Timing matters, too. When you recognize sales on your P&L may differ from when you log matching COGS. That mismatches gross and net profit.
Sometimes finance teams chase better net profit but ignore dropping gross margin. That gives a short-term boost but weakens the fundamentals. Gross margin troubles show up down the road, especially in hiring or resource planning.
Calculating gross profit and net profit in Runway
Runway takes the manual work out of these metrics. Connect your accounting system and let it pull in revenue and expenses. The platform auto-categorizes using your chart of accounts, but you can adjust as needed.
Start by defining your COGS categories. Runway lets you build cost centers and clear allocation rules. Separate direct costs from operating expenses, every time. For service businesses, you’ll want to create cost-of-services lines for direct labor and project costs.
Collaborate to avoid classification mistakes. Team members can review and comment before numbers hit your reports. Runway’s collaborative forecasting keeps teams synced, catching errors sooner.
Scenario planning is where it really clicks. Quickly model different cost setups and see effects on both profit lines. Runway lets you test pricing, cost cuts, or new investments with no risk to your core model.
How Runway Handles Gross Profit vs Net Profit
Runway helps you set these up cleanly, and keeps them visible across forecasts, reports, and decisions.
Here’s how:
- Connect your accounting system to pull in revenue and expenses.
- Define COGS and cost-of-services categories.
- Create operating-expense line items with clear allocation rules.
- Invite your team to review classifications in real time.
- Run scenario analyses to compare gross and net profit impacts.
Gross profit vs net profit FAQ
How do currency fluctuations affect my gross and net profit reporting?
Currency shifts change revenue, COGS, and expenses when you deal in foreign currencies. Exchange rates hit both profit lines.
If you sell in dollars but buy in euros, a stronger euro squeezes gross margins. Net profit faces extra changes from foreign exchange gains or losses, which you track as non-operating items.
Stay ahead with natural hedging, forward contracts, or currency options. Model different exchange rates to see exposure and adjust your strategy.
Should I include non-operational gains and losses in my net profit calculation?
Yes. Count them for a full net profit view, but always track them separately. Non-operating items change net income and investor perception, but don’t show day-to-day business strength.
Build clear lines for these in your models. Show both GAAP net profit and an adjusted number without one-time items for more clarity. If charges keep recurring, reclassify them — sometimes "non-recurring" is actually routine.
How can I use gross and net profit analytics to drive cross-functional collaboration?
Share profit metrics in a clear, easy-to-understand way. Sales teams care how pricing affects gross margins. Marketing wants to see how acquisition costs shift net profit. Ops teams need to know how better efficiency lifts the bottom line.
Build dashboards showing real-time profit impacts by department. When marketing boosts spend, show net profit changes and longer-term revenue upside. When ops improves, highlight gross margin wins.
Cross-team meetings work best when you link profit data to real actions — like smarter hiring or investment decisions. Finance leads by turning data into strategy, not just reporting.
