Ever looked at your business's sales numbers and wondered where all that money actually goes? You're not alone.

Many entrepreneurs celebrate hitting revenue milestones only to discover they're still struggling to keep the lights on. The disconnect often comes down to one critical number: gross profit.

Understanding gross profit isn't just accounting jargon—it's the difference between a business that looks successful on paper and one that actually puts money in your pocket. In this guide, I'll walk you through everything you need to know about calculating and improving your gross profit, with real examples to make these concepts crystal clear.

What Is Gross Profit (And Why Should You Care)?

Gross profit is the money left over from your sales after subtracting the direct costs of making your product or delivering your service. It's your revenue minus your cost of goods sold (COGS).

Why does this matter? Because gross profit tells you:

  • If your products are priced correctly

  • How much money you have to cover operating expenses

  • Whether your business model is fundamentally sound

  • Where you stand compared to competitors

Think of gross profit as your business's "breathing room." Without healthy gross profit, you'll constantly be gasping for financial air.

The Gross Profit Formula: Simple But Powerful

The formula for calculating gross profit is refreshingly straightforward:

Gross Profit = Revenue - Cost of Goods Sold (COGS)

Let's break down each component:

Revenue

This is your total sales before any expenses are deducted. It's all the money coming into your business from selling products or services.

Cost of Goods Sold (COGS)

These are the direct costs associated with making your products or delivering your services, including:

  • Raw materials

  • Direct labor costs

  • Manufacturing supplies

  • Equipment directly used in production

  • Shipping and freight

  • Product packaging

What's NOT included in COGS:

  • Marketing and advertising costs

  • Office rent and utilities

  • Administrative salaries

  • Sales team commissions

  • Insurance and legal fees

These non-COGS expenses are important, but they're considered operating expenses, not direct costs of goods sold.

Calculating Gross Profit: Step-by-Step Examples

Let's walk through some practical examples to see gross profit calculations in action.

Example 1: A Retail Business

Sarah's Boutique sells handmade jewelry. Here's her monthly breakdown:

  • Total jewelry sales: KSh 500,000

  • Cost of silver and gems: KSh 150,000

  • Direct labor to make jewelry: KSh 100,000

  • Packaging materials: KSh 25,000

Step 1: Calculate total revenue

  • Revenue = KSh 500,000

Step 2: Calculate COGS

  • COGS = KSh 150,000 + KSh 100,000 + KSh 25,000 = KSh 275,000

Step 3: Calculate gross profit

  • Gross Profit = KSh 500,000 - KSh 275,000 = KSh 225,000

Sarah's gross profit is KSh 225,000, meaning she has this amount available to cover rent, marketing, her own salary, and other operating expenses.

Example 2: A Service Business

Daniel's Web Design Agency creates websites for small businesses. Here's his monthly breakdown:

  • Web design service revenue: KSh 800,000

  • Freelancer payments (direct labor): KSh 300,000

  • Website hosting costs passed to clients: KSh 50,000

  • Software licenses for design work: KSh 30,000

Step 1: Calculate total revenue

  • Revenue = KSh 800,000

Step 2: Calculate COGS

  • COGS = KSh 300,000 + KSh 50,000 + KSh 30,000 = KSh 380,000

Step 3: Calculate gross profit

  • Gross Profit = KSh 800,000 - KSh 380,000 = KSh 420,000

Daniel's gross profit is KSh 420,000, which he can use to pay for office space, marketing, administrative staff, and other operating expenses.

Beyond the Number: Understanding Gross Profit Margin

While the gross profit amount is important, the gross profit margin gives you a better perspective on your business's efficiency. This is expressed as a percentage:

Gross Profit Margin = (Gross Profit ÷ Revenue) × 100

Using our examples:

Sarah's Boutique: (KSh 225,000 ÷ KSh 500,000) × 100 = 45% gross profit margin

Daniel's Web Design: (KSh 420,000 ÷ KSh 800,000) × 100 = 52.5% gross profit margin

This tells us that for every shilling of sales, Sarah keeps 45 cents and Daniel keeps 52.5 cents to cover operating expenses and hopefully generate net profit.

Common Mistakes When Calculating Gross Profit

Even experienced business owners sometimes make these errors when calculating gross profit:

1. Mixing Up Operating Expenses and COGS

The mistake: Including general business expenses like office rent or administrative salaries in COGS.

Why it matters: This artificially lowers your gross profit and prevents you from seeing the true profitability of your products or services.

Example: If Sarah incorrectly included her boutique's rent (KSh 50,000) in COGS, her gross profit would appear to be KSh 175,000 instead of KSh 225,000, and her gross margin would drop from 45% to 35%.

2. Forgetting to Include All Direct Costs

The mistake: Leaving out some direct costs like shipping or packaging.

Why it matters: This inflates your gross profit and gives you a false sense of product profitability.

Example: If Daniel forgot to include the software license costs (KSh 30,000) in his COGS, his gross profit would appear to be KSh 450,000 instead of KSh 420,000, and his margin would seem to be 56.25% instead of 52.5%.

3. Using Inconsistent Time Periods

The mistake: Comparing revenue from one period with COGS from another.

Why it matters: This creates misleading gross profit calculations that don't reflect your business's actual performance.

Example: Calculating January's gross profit using January's sales but December's inventory purchases would create a distorted picture.

Interpreting Your Gross Profit: What Does It Tell You?

Your gross profit and margin aren't just numbers—they're powerful indicators of your business's health:

High Gross Profit Margin

If your gross margin is high compared to industry standards, it suggests:

  • Your products or services are priced effectively

  • You're managing direct costs efficiently

  • You have a strong value proposition that allows premium pricing

Low Gross Profit Margin

If your gross margin is low, it could indicate:

  • Your prices may be too low

  • Your direct costs are too high

  • You might be in a highly competitive market with price pressure

  • Your product mix might favor lower-margin items

Industry Benchmarks: How Do You Compare?

Different industries have vastly different typical gross margins. Here's a quick reference:

  • Retail (general): 25-45%

  • Restaurants: 60-70%

  • Manufacturing: 20-35%

  • Software/Digital Products: 70-85%

  • Professional Services: 50-70%

  • Construction: 15-30%

Remember, these are averages. The best comparison is against direct competitors in your specific niche.

5 Proven Strategies to Improve Your Gross Profit

If you've calculated your gross profit and aren't happy with the results, here are five actionable ways to improve it:

1. Optimize Your Pricing Strategy

Could you increase prices without significantly impacting sales volume? Many businesses undercharge for their products or services. Consider:

  • Testing small price increases on select products

  • Creating premium versions with higher margins

  • Implementing value-based pricing instead of cost-plus pricing

2. Reduce Direct Costs

Look for ways to lower your COGS without sacrificing quality:

  • Negotiate better terms with suppliers

  • Buy materials in bulk for discounts

  • Improve production efficiency to reduce labor costs

  • Minimize waste in the production process

3. Change Your Product Mix

Not all products are created equal when it comes to profitability:

  • Identify your highest-margin products and promote them more aggressively

  • Consider discontinuing extremely low-margin products

  • Develop new offerings with inherently higher margins

4. Review Your Payment Processing Costs

Payment processing fees directly impact your gross profit, especially for e-commerce and digital businesses:

  • Shop around for better payment processing rates

  • Consider platforms like IntaSend that offer competitive rates for African businesses

  • Analyze which payment methods cost you the most and adjust accordingly

5. Streamline Your Fulfillment Process

For physical products, optimizing how you get products to customers can significantly impact gross profit:

  • Evaluate shipping carriers and negotiate better rates

  • Consider alternative packaging that costs less but maintains product protection

  • Analyze your inventory management to reduce storage costs

Tracking Gross Profit Over Time: The Key to Growth

Calculating gross profit isn't a one-time exercise—it should be monitored regularly:

  • Monthly tracking: Spot seasonal trends and immediate issues

  • Quarterly analysis: Identify broader patterns and the impact of strategic changes

  • Annual review: Compare year-over-year performance and set new targets

Many accounting software packages calculate gross profit automatically, making this process much simpler than it was historically.

Beyond Gross Profit: The Complete Financial Picture

While gross profit is crucial, it's just one part of your business's financial health. To get a complete picture, you should also understand:

  • Operating profit: What remains after deducting operating expenses from gross profit

  • Net profit: The final bottom line after all expenses, including taxes and interest

  • Cash flow: How money actually moves in and out of your business, which can differ from profit calculations

Simplifying Financial Management with Digital Tools

Modern businesses don't need to calculate these metrics manually. Tools like QuickBooks, Xero, or Wave automatically generate gross profit reports. Additionally, payment platforms like IntaSend provide detailed transaction reports that make it easier to track revenue accurately—a critical component of gross profit calculations.

For African businesses in particular, integrating payment systems that offer comprehensive reporting can streamline the process of calculating and monitoring gross profit. This is especially valuable for businesses operating across borders or handling multiple currencies.

Conclusion: Gross Profit as Your Business Compass

Understanding and regularly calculating your gross profit gives you a reliable compass for business decisions. It helps you answer critical questions like:

  • Should we raise or lower our prices?

  • Which products should we focus on promoting?

  • Can we afford to hire more staff?

  • Is our business model fundamentally sound?

By mastering this essential financial metric, you transform from a business owner who hopes for the best to one who steers with confidence and clarity.
