Inch Calculator

A Return on Equity (ROE) Calculator is a tool that measures how effectively a company uses shareholders’ equity to generate profit. Investors often use it to evaluate a company’s profitability and management efficiency.

ROE Formula

$$\text{ROE} = \left( \frac{\text{Net Income}}{\text{Shareholders’ Equity}} \right) \times 100$$ROE=(Shareholders’ EquityNet Income​)×100

Where:

• Net Income = Company’s profit after taxes.
• Shareholders’ Equity = Total assets minus total liabilities.

Example

Suppose a company has:

• Net Income: $500,000
• Shareholders’ Equity: $2,500,000

Calculation:$$\text{ROE} = \left( \frac{500,000}{2,500,000} \right) \times 100 = 20\%$$ROE=(2,500,000500,000​)×100=20%

The company’s ROE is 20%.

What ROE Tells You

• Higher ROE generally indicates the company is generating more profit from each dollar of shareholder investment.
• Lower ROE may suggest less efficient use of equity.
• ROE should usually be compared with:
  • Competitors in the same industry
  • The company’s historical ROE
  • Industry averages

How a ROE Calculator Helps

A ROE calculator can:

• Quickly compute ROE from financial statements.
• Compare multiple companies.
• Track profitability trends over time.
• Support stock investment decisions.

Interpreting ROE

A rough guideline (varies by industry):

• Below 10%: Often considered weak
• 10%–15%: Moderate
• 15%–20%: Strong
• Above 20%: Very strong, though sometimes boosted by high debt

For Rental Real Estate

Real estate investors sometimes use a different “return on equity” calculation:$$\text{ROE} = \left( \frac{\text{Annual Cash Flow} + \text{Principal Paydown} + \text{Appreciation}}{\text{Current Equity}} \right) \times 100$$ROE=(Current EquityAnnual Cash Flow+Principal Paydown+Appreciation​)×100

This measures how efficiently the equity tied up in a property is producing returns and can help decide whether to keep a property or reinvest elsewhere.
