What Is Net Profit and How to Know If Your Business Is Actually Making Money in Nigeria

What Is Net Profit and How to Know If Your Business Is Actually Making Money in Nigeria

Introduction

Here is a question that makes many Nigerian business owners uncomfortable: is your business actually making money?

Not turnover. Not gross profit. Not the number in your bank account after your last big sale. Real, bottom-line, after-everything profit.

The honest answer for many merchants is: I am not sure. And that uncertainty is not laziness it is a direct result of not having a clear, reliable way to calculate net profit regularly.

Net profit is the final number. It is what remains after every cost your business incurs has been deducted the products you sold, the delivery fees, the staff salaries, the rent, the advertising, the data subscriptions, and everything else. It is the truest measure of whether your business is financially healthy or quietly bleeding money.

This article explains what net profit is, how to calculate it step by step, what healthy net margins look like for different Nigerian business types, and how Zerrar gives you this number automatically so you never have to guess again.

What Is Net Profit?

Net profit is the amount of money your business keeps after all costs both the cost of goods sold and all operating expenses have been deducted from your total revenue.

It is called net profit because it is the profit figure after everything has been netted out. Nothing else comes off after this. What remains is what your business truly earned.

Formula: Net Profit = Turnover − Cost of Goods Sold − Operating Expenses

Or expressed another way: Net Profit = Gross Profit − Operating Expenses

This is the bottom line on your Profit and Loss statement. Every other financial figure turnover, gross profit, margins exists to help you understand and improve this number.

Why Is Net Profit the Most Important Number in Your Business?

It tells you the truth. Turnover tells you how much passed through your business. Gross profit tells you how much you kept after paying suppliers. Net profit tells you how much you actually made. It is the only number that accounts for everything.

It determines whether your business is sustainable. A business that consistently generates net profit is sustainable. A business that consistently generates a net loss is consuming its owner's money and savings and will eventually fail unless something changes.

It is what you actually take home. Whether you pay yourself a salary or take owner withdrawals, net profit is the pool from which that money ultimately comes. No net profit means no sustainable income from the business.

It determines your tax liability. Company Income Tax in Nigeria is calculated on your profit not your turnover. Knowing your net profit means knowing exactly what your tax exposure is.

It is the number banks and investors care about most. Any lender or investor evaluating your business will focus on net profit. It is the ultimate measure of financial performance.

Net Profit vs Gross Profit: Understanding the Difference

Many Nigerian business owners confuse gross profit and net profit or use them interchangeably. They are not the same.

Gross profit is what remains after deducting only the cost of goods sold from your turnover. It does not account for rent, salaries, advertising, delivery, or any other running costs.

Net profit is what remains after deducting both the cost of goods sold and all operating expenses. It is the complete picture.

The gap between gross profit and net profit is your total operating expenses. A wide gap means your overheads are high. A narrow gap means you are running an efficient operation.

A business with high gross profit but low or negative net profit has an overhead problem. A business with low gross profit will struggle to generate meaningful net profit no matter how lean it runs.

Both margins need to be healthy for your business to thrive.

How to Calculate Net Profit: Step-by-Step

Step 1: Calculate your turnover for the period. Add up all sales revenue received during the period cash, card, transfer, and online payments.

Step 2: Calculate your Cost of Goods Sold (COGS). Add up the direct cost of all products you sold during the period, including supplier costs, import duties, and freight costs to receive the goods.

Step 3: Calculate your Gross Profit. Subtract COGS from turnover.

Step 4: List and total all operating expenses. Include every cost of running your business that is not COGS delivery to customers, packaging, advertising, staff salaries, rent, utilities, data, bank charges, platform fees, and everything else.

Step 5: Subtract total operating expenses from gross profit. The result is your net profit.

Step 6: Calculate your net profit margin. Divide net profit by turnover and multiply by 100.

Worked Example Adaeze's Complete January P&L

Continuing with Adaeze's fashion business from across this series:

Amount

TURNOVER

₦226,000

Cost of Goods Sold

−₦108,000

GROSS PROFIT

₦118,000

Delivery fees

−₦15,000

Packaging materials

−₦5,000

Instagram advertising

−₦10,000

Platform commission

−₦11,300

Data and phone

−₦3,000

Miscellaneous

−₦2,000

Total Operating Expenses

−₦46,300

NET PROFIT

₦71,700

Net Profit Margin: ₦71,700 ÷ ₦226,000 × 100 = 31.7%

For every ₦100 Adaeze earns from sales, she keeps approximately ₦32 as real profit. The remaining ₦68 covered the cost of her products and the cost of running her business.

At this margin, Adaeze's business is performing well above average for a Nigerian fashion merchant.

What Is a Healthy Net Profit Margin in Nigeria?

Net margins vary by business type, but here are realistic benchmarks for Nigerian product-based merchants:

Business Type

Typical Net Margin

Fashion and clothing

20 – 35%

Hair and wigs

18 – 30%

Beauty and cosmetics

25 – 40%

Food and meal prep

10 – 20%

Home décor

20 – 30%

Jewellery

25 – 40%

If your net margin is consistently below these ranges, one or more of the following is true:

• Your selling prices are too low
• Your supplier costs are too high
• Your operating expenses are too high relative to your revenue
• You are not recording all your revenue correctly
• You are not recording all your costs correctly

Each of these is a fixable problem but only once you can see it clearly.

What Is Net Profit Margin?

Net profit margin is your net profit expressed as a percentage of your turnover. It tells you what proportion of every naira earned from sales your business keeps as real profit after all costs.

Formula: Net Profit Margin (%) = (Net Profit ÷ Turnover) × 100

Net profit margin is one of the most useful comparative tools available to a business owner. It lets you:

• Compare your profitability this month against last month
• Compare your business against industry benchmarks
• See the impact of a price increase or cost reduction on your bottom line
• Identify whether growth in turnover is translating into growth in real profit

A business growing its turnover but shrinking its net margin is working harder for less. That is a warning sign worth catching early.

The Difference Between Net Profit and Cash in Your Account

This is one of the most important distinctions in business finance and one of the most commonly misunderstood by Nigerian merchants.

Your bank account balance is not your net profit.

Money sitting in your account may include:

• VAT collected on behalf of FIRS that you have not yet remitted
• Customer deposits for orders not yet fulfilled
• Money from loans or personal injections into the business
• Sales revenue from stock not yet restocked

At the same time, your net profit calculation may not yet reflect:

• Invoices sent but not yet paid
• Stock purchased but not yet sold
• Upcoming expenses already committed to

This is why profitable businesses can still have cash flow problems and why cash flow is tracked separately from profit. Net profit measures financial performance. Cash flow measures liquidity.

Can a Business Have High Turnover But Low Net Profit?

Absolutely and it is more common than most people realise.

Consider two businesses:

Business A:

• Turnover: ₦2,000,000
• COGS: ₦1,400,000
• Operating Expenses: ₦500,000
• Net Profit: ₦100,000
• Net Margin: 5%

Business B:

• Turnover: ₦800,000
• COGS: ₦320,000
• Operating Expenses: ₦160,000
• Net Profit: ₦320,000
• Net Margin: 40%

Business A is turning over 2.5 times more than Business B but making less than a third of the profit. Business B is far more financially healthy despite its smaller size.

High turnover with low net margin means you are very busy but not necessarily prosperous. The goal is not the biggest turnover it is the healthiest net margin.

Common Mistakes to Avoid

Confusing bank balance with profit Your account balance at any moment is not your net profit. It includes money that is not yours VAT owed to FIRS, customer deposits, loan proceeds and excludes upcoming expenses already committed.

Not accounting for all expenses Many Nigerian merchants mentally track their big expenses rent, salaries but forget to record smaller recurring costs. Over a year, unrecorded expenses of ₦5,000 to ₦10,000 per month represent ₦60,000 to ₦120,000 of invisible cost that inflates your apparent profit.

Celebrating gross profit as if it were net profit Gross profit is not what you made. It is what you made before running the business. Net profit is what you actually made. Always know the difference.

Not calculating net profit regularly Waiting until year-end to calculate your net profit means you discover problems too late to fix them. Monthly net profit calculation is the minimum for a well-managed business.

Including personal withdrawals as expenses Money you take out of the business for personal use is not a business expense. It is an owner's withdrawal. Recording it as an expense artificially reduces your net profit and gives a false picture of business performance.

How to Improve Your Net Profit

There are only three levers available to improve net profit:

1. Increase turnover More sales at the same margins produce more gross profit and therefore more net profit provided operating expenses do not increase proportionally.

2. Improve gross margin Better supplier prices or higher selling prices increase gross profit without necessarily increasing operating expenses directly improving net profit.

3. Reduce operating expenses Lower overheads mean more of your gross profit flows through to net profit. Review every expense category monthly and look for reduction opportunities.

The most powerful improvements usually combine all three modest gains in each lever compounding into a significantly healthier net margin.

Frequently Asked Questions

What is the difference between net profit and net income? They mean the same thing. Net profit and net income both refer to the amount remaining after all costs and expenses have been deducted from revenue.

Is net profit the same as cash flow? No. Net profit is an accounting measure of financial performance. Cash flow is the actual movement of cash in and out of your business. A business can be profitable but cash flow negative for example if customers owe you money or if cash is tied up in unsold stock.

What if my net profit is negative? A negative net profit means you made a loss your total costs exceeded your total revenue. Occasional losses during growth phases are normal, but persistent losses require immediate investigation into pricing, costs, or both.

How is net profit taxed in Nigeria? Company Income Tax (CIT) in Nigeria is applied to your taxable profit which is broadly your net profit after certain adjustments. Businesses with annual turnover below ₦50 million pay 0% CIT. Those between ₦50 million and ₦100 million pay 20%. Those above ₦100 million pay 30%.

Should I calculate net profit monthly or annually? Both. Monthly net profit calculation keeps you informed and allows early course correction. Annual net profit is required for tax filings and formal financial reporting.

My net profit looks good but I have no money in my account. Why? This is a cash flow issue, not a profit issue. Your profit may be real, but the cash may be tied up in unpaid invoices, unsold stock, or upcoming expenses. Cash flow management is a separate discipline from profit tracking.

Does Zerrar calculate my net profit automatically? Yes provided you record your cost prices on products and log your operating expenses in the platform. Zerrar combines your sales data, COGS, and expense records to show your net profit in real time.

Conclusion

Net profit is the number that tells the whole truth about your business. Not turnover, not gross profit, not your bank balance net profit. It is the final, complete measure of whether your business is financially healthy after everything has been accounted for.

Nigerian merchants who track their net profit monthly make better pricing decisions, catch cost problems early, manage their taxes correctly, and build businesses that actually sustain them. Those who do not are always guessing and guessing is expensive.
