In finance and investment analysis, not all profits are created equal. Traditional income measures like net income or EBITDA often miss a key insight: How much value is truly being created after accounting for the cost of capital? This is where residual income becomes a powerful tool.
Our Residual Income Calculator helps you determine how much income remains after deducting the opportunity cost of capital. Whether you’re analyzing a business, evaluating investment decisions, or tracking your own personal wealth-building, this calculator gives you a precise financial picture.

📘 What is Residual Income?
Residual income is the net income a business or individual has left after subtracting the required rate of return (cost of capital) on assets or investments. It helps answer the question: “Am I truly making more than the minimum expected return?”
In corporate finance, residual income is a measure of economic profit — unlike accounting profit, it reflects whether a company is actually generating value for shareholders beyond capital costs.
In personal finance, residual income can also refer to the amount of money left after all personal debts and expenses are paid — often used by lenders when evaluating loan applications.
🧮 Residual Income Formula (Plain Text)
In a corporate or investment setting, residual income is calculated using this formula:
javaCopyEditResidual Income = Net Operating Income - (Average Operating Assets × Minimum Required Rate of Return) Where:
- Net Operating Income (NOI) = Income before interest and taxes
- Average Operating Assets = Assets used to generate income
- Minimum Required Rate of Return = Also called the cost of capital or hurdle rate
For personal finance use:

🧾 Example Calculation
Example 1: Business/Investor Use
Let’s say:
- Net Operating Income = $120,000
- Average Operating Assets = $800,000
- Minimum Required Rate of Return = 10%
nginxCopyEditResidual Income = 120,000 - (800,000 × 0.10) = 120,000 - 80,000 = $40,000 Conclusion: The business created $40,000 in economic profit over and above its cost of capital.
Example 2: Personal Finance Use
Let’s say:
- Monthly Income = $6,000
- Monthly Expenses (bills, debts, loans) = $4,200
nginxCopyEditResidual Income = 6,000 - 4,200 = $1,800 Conclusion: You have $1,800 in monthly residual income for saving or discretionary spending.
