What are Financial Ratios?
Financial ratios formulas for entrepreneurs are numbers that tell you the truth about your business’s financial health. They are mathematical comparisons that show how healthy your company really is over a specific period. Instead of guessing, these ratios help you see whether your business is growing, struggling, or just stagnant.
They also allow you to measure your performance against competitors in your industry. With the proper ratios, you can tell if you’re ahead, behind, or right on track. In simple terms, financial ratios help you understand your business’s strengths, weaknesses, efficiency, and overall financial position at a glance.
Why should you know Financial Ratios/Formulas?
Because I watch a lot of business shows and investor pitches, one thing has become very clear: when you sit in front of an investor asking for funding, there are a few things they immediately want to understand:
- What your business or idea is about
- Who you are as a founder or team
- What your numbers are saying
And of all three, I’ve noticed something interesting: investors will argue with you about your idea, they may even question your personality, but the moment you start talking numbers, the entire conversation changes.
In fact, the only reason an investor would walk away from a business with significant numbers is a lack of integrity on the part of the entrepreneur. But with substantial numbers, even a “not-so-brilliant” business idea can get praise and, many times, even funding.
Why? Because numbers don’t lie, they are proof that the business is alive, functioning, and has a future. Numbers show traction, potential, and sustainability, things no investor can ignore.
Let’s look at five terms that will help you stay ahead of the game in your business, and mind you, this has little or nothing to do with the size of your business. The earlier the better.
Five Key Financial Ratios or Formulas
Net Income
Net income, often called “the bottom line,” is the amount of money a business or person has left over after paying all their bills, taxes, and other obligations.
Let’s narrow it down to a business; Net income shows how much value a corporation has created for its shareholders. The company can use this money to reinvest in itself, pay off debts, or give dividends. It is reported at the bottom of the income statement.
The basic equation for a business’s net revenue is:
Net Income Formula: Total Income – Total Expenses
Example Calculation: A typical example is to state, in 2025, what our Direct costs of producing, plus operating costs, interest costs, taxes, and non-operating gains or losses were. The addition of all of these will be the total expenses. Let’s say the total expenditures were 150,000 dollars, and the business sold products and grossed 450,000 dollars. Then the net profit is:
Total Income – Total Expenses
$450 000 – $150 000 = $300 000
Debt to Equity
I have written a blog post on Financial leverage; make sure to read it. With proper financial leverage, any business can easily rise to the top. Leveraging other people’s money to achieve your dreams and business aspirations can be the key to that global business you have envisioned. However, the big question is, how do I even know if I am leveraging the right way or not?
With the debt-equity ratio, you can adequately assess the amount of money that is currently funding your business, which is a debt. A debt is considered a liability. The debt-equity ratio shows whether you are still alive or just breathing with an Oxygen tank underwater.

Current Ratio
I always say this: cash flow is the real heartbeat of any business. You can have excellent products, great branding, and even loyal customers, but if you can’t pay your short-term bills, your business will struggle to stand. That’s where the current ratio comes in.
The current ratio helps you determine whether your business can comfortably cover its short-term obligations with the assets you already have on hand. In simple terms, it compares what you own (your cash, inventory, and receivables) to what you owe in the next 12 months. When this number is above 1, it means you have enough current assets to cover your immediate bills. If it’s less than 1, it’s a sign that you may be stretching your business thin.
But here’s the interesting part: an extremely high current ratio isn’t always good either. It could mean your money is just sitting there doing nothing when it could be working for you. The current ratio helps you spot how balanced you are: whether you’re financially healthy, barely surviving, or holding too much idle cash.
Current Ratio Formula: Current Assets / Current Liabilities
Return on Equity
Return on Equity (ROE) is a key business ratio that indicates the profit a business generates relative to the amount invested by shareholders. In short, it is the profit generated from doing business with the money shareholders invest. One can easily calculate by using the formula.
To get this number, you divide a company’s net income by its average shareholders’ equity, expressed as a percentage. A higher ROE generally indicates that a company is more efficient at maximising equity to generate profits, making it more attractive to investors. A higher ROE generally suggests that a company is more efficient at using its equity to create profits, making it more desirable to investors.
ROE (%) Formula: Net Income / Shareholders’ Equity
Net Profit Margin
Net profit margin shows how much of each dollar of revenue is left after all expenses, including taxes, interest, and operating costs, have been subtracted. The net profit margin is calculated by dividing net profit by total revenue and multiplying by 100%. A higher percentage indicates that a company is better at turning revenue into real profit, highlighting its effectiveness.
Net profit margin provides a closer view of a business’s profitability by accounting for all costs, unlike gross profit margin, which considers only the cost of goods sold. A higher net profit margin can also signal better financial health, indicating that more cash is available for reinvestment or shareholder distribution. Additionally, it reflects how efficiently a company manages its expenses to generate profit from its sales.
Formula for Net Profit Margin: Net Profit / Net Sales

Final Note
Every business relies on its leader or leadership team to monitor the key numbers that drive success. Ignoring these figures and acting on impulse will restrict your results.
