7 Financial Ratios Every Small Business Owner Should Know

7 Financial Ratios Every Small Business Owner Should Know

Financial statements are overwhelming. Hundreds of numbers, but which ones actually matter? These 7 ratios cut through the noise and tell you exactly how your business is performing.

Why Ratios Matter

Raw numbers are meaningless without context. "$50,000 profit" sounds great until you learn it required $5 million in sales. Ratios provide that context.

They also enable:

Ratio 1: Gross Profit Margin

**Formula:** (Revenue - COGS) ÷ Revenue × 100

**What it tells you:** How much you keep from each sale after direct costs.

Example:

Benchmarks:

**If it's declining:** Your costs are rising faster than prices, or you're discounting too much.

Ratio 2: Net Profit Margin

**Formula:** Net Income ÷ Revenue × 100

**What it tells you:** What percentage of revenue becomes actual profit after ALL expenses.

Example:

Benchmarks:

**If it's low:** Either gross margins are thin OR operating expenses are too high. Check both.

Ratio 3: Current Ratio

**Formula:** Current Assets ÷ Current Liabilities

**What it tells you:** Can you pay bills due within the next year?

Example:

Benchmarks:

Ratio 4: Quick Ratio (Acid Test)

**Formula:** (Current Assets - Inventory) ÷ Current Liabilities

**What it tells you:** Same as current ratio, but excludes inventory (which might not sell quickly).

Example:

**Benchmark:** Above 1.0 is ideal. If your quick ratio is much lower than your current ratio, you're inventory-heavy.

Ratio 5: Inventory Turnover

**Formula:** COGS ÷ Average Inventory

**What it tells you:** How many times you sell through inventory per year.

Example:

What's good?

**Low turnover means:** Cash tied up in slow-moving products. Time to discount or stop ordering.

Ratio 6: Accounts Receivable Turnover

**Formula:** Net Credit Sales ÷ Average Accounts Receivable

**Days Sales Outstanding (DSO):** 365 ÷ AR Turnover

**What it tells you:** How quickly customers pay.

Example:

**Benchmark:** Should be close to your payment terms. If you offer Net 30 but DSO is 45, you have a collections problem.

Ratio 7: Debt-to-Equity Ratio

**Formula:** Total Liabilities ÷ Owner's Equity

**What it tells you:** How much of your business is funded by debt vs. owner investment.

Example:

Benchmarks:

**Why it matters:** Banks look at this when you apply for loans. High debt limits future borrowing ability.
