When we look at how well a company is doing, financial ratios act like simple tools that help us understand its money situation. As a Year 11 student learning about ratios and proportions, I think it's interesting how math is so important in the finance world.

What Are Financial Ratios?

Financial ratios are simple math calculations taken from a company's financial statements, like the balance sheet and income statement. They help us see different parts of how a business is doing, such as how much money it makes, how well it uses its assets, and whether it can pay its bills. Here are some main types of financial ratios and what they tell us:

1. Profitability Ratios:

   • Gross Profit Margin: This ratio shows how much money a company makes after covering the cost of the items it sells. You can calculate it like this: $\text{Gross Profit Margin} = \frac{\text{Gross Profit}}{\text{Revenue}} \times 100$
   • A higher margin means the company is making more profit.

2. Liquidity Ratios:

   • Current Ratio: This tells us if a company can pay its short-term bills. Here's the formula: $\text{Current Ratio} = \frac{\text{Current Assets}}{\text{Current Liabilities}}$
   • A good number is usually above 1, which shows the company can cover its short-term debts.

3. Efficiency Ratios:

   • Inventory Turnover Ratio: This measures how well a company sells and replaces its inventory. You can find it using: $\text{Inventory Turnover} = \frac{\text{Cost of Goods Sold}}{\text{Average Inventory}}$
   • A higher ratio means the company is doing a great job managing its inventory.

4. Solvency Ratios:

   • Debt to Equity Ratio: This shows how much debt a company has compared to its own money: $\text{Debt to Equity} = \frac{\text{Total Liabilities}}{\text{Shareholders' Equity}}$
   • A lower number is better since it means less risk for investors.

Real-World Use

In the real world, these ratios give investors valuable information. By looking at these numbers, they can get a good idea of how a company is doing without having to dig through lots of financial papers. For example, if a tech startup is growing quickly but doesn't have a good gross profit margin, investors might think twice about its long-term success.

Also, ratios help compare one company to another. If one business has a current ratio of 2 and another has 1, the first company might be better at handling its short-term bills.

Conclusion

In the end, financial ratios are more than just numbers; they tell us about how well a company is running, how much money it makes, and how stable it is. As you study these ideas in Year 11 math, it’s clear that they play a big role in finance. They turn complicated financial data into simple and helpful insights for investors, which guide their choices in the market.
