As an ACCA finalist who's analyzed thousands of businesses, I've seen too many ecommerce owners focus solely on revenue while ignoring the financial health indicators that predict long-term success or failure.

These five ratios will give you the same financial insights that professional analysts use to evaluate businesses. Master them, and you'll make better decisions about pricing, inventory, growth investments, and cash flow management.

Why Financial Ratios Matter

Revenue tells you what happened. Ratios tell you why it happened and what to expect next. They're the difference between growing blindly and growing strategically.

1
Gross Profit Margin

Formula
(Revenue - Cost of Goods Sold) ÷ Revenue × 100%

What it measures: How efficiently you price your products relative to their direct costs

Healthy Range
40-60% for most ecommerce
Warning Sign
Below 30% consistently

Why it matters: A healthy gross margin ensures you have enough left over to cover marketing, operations, and growth investments. In competitive ecommerce markets, tracking this ratio helps you stay profitable even with discounts.

2
Net Profit Margin

Formula
Net Profit ÷ Revenue × 100%

What it measures: What percentage of revenue becomes actual profit after all expenses

Healthy Range
10-20% for sustainable growth
Growth Stage
5-10% while scaling

Why it matters: Revenue growth means nothing if expenses grow faster. This ratio ensures your growth is sustainable and profitable, not just driven by top-line sales that burn cash.

3
Current Ratio

Formula
Current Assets ÷ Current Liabilities

What it measures: Your ability to pay short-term obligations like supplier invoices and upcoming bills

Healthy Range
1.5 - 2.0 for ecommerce
Warning Sign
Below 1.0 consistently

Why it matters: A ratio of 1.5-2.0 means you have $1.50-$2.00 in short-term assets for every $1.00 of short-term debt. This cushion protects you from cash flow problems during seasonal dips or unexpected expenses.

4
Inventory Turnover

Formula
Cost of Goods Sold ÷ Average Inventory

What it measures: How quickly you sell and replenish your stock

Healthy Range
4-12 times per year
Days in Inventory
30-90 days typically

Why it matters: High turnover means efficient selling without tying up cash in dead stock. Low turnover suggests overstocking, poor product selection, or pricing issues. This ratio directly impacts cash flow and profitability.

5
Return on Assets (ROA)

Formula
Net Income ÷ Total Assets × 100%

What it measures: How effectively you use your business assets to generate profit

Healthy Range
15-25% for ecommerce
Excellent
Above 25%

Why it matters: Every dollar invested in inventory, marketing tools, or infrastructure should generate returns. ROA helps you evaluate whether investments in new assets will improve profitability or just tie up capital.
