Formula and Logic
Personal Residual Income
Residual Income = Monthly Gross Income - (Monthly Taxes + Monthly Housing Expenses + Monthly Recurring Debt Payments + Monthly Living Expenses)
Adjusted Residual Income = Residual Income - (Maximum(0, Number of Dependents - 1) * $250) (based on common VA loan adjustment guidelines)
Debt-to-Income Ratio = ((Monthly Recurring Debt + Monthly Housing Expenses) / Monthly Gross Income) * 100
Corporate Residual Income
Residual Income = Net Operating Profit After Tax (NOPAT) - (Total Equity Capital * Cost of Equity Percentage / 100)
Equity Charge = Total Equity Capital * (Cost of Equity Percentage / 100)
Return on Equity (ROE) = (NOPAT / Total Equity Capital) * 100
Practical Notes
Personal residual income is a key factor in mortgage and loan approvals, especially for VA and FHA loans. Lenders prefer residual income that covers at least 1.2x your basic living expenses.
Cost of equity for corporate calculations is typically the expected return shareholders demand, often based on the risk-free rate plus a risk premium.
Tax amounts should include federal, state, and local income taxes withheld from your paycheck for accurate personal calculations.
Recurring debt payments only include minimum required payments (e.g., credit card minimums, not full balances paid).
Corporate residual income that is positive indicates the company is generating returns above its cost of capital, creating value for shareholders.

Frequently Asked Questions
What is a good residual income for loan approval?
For personal loans, most lenders require at least $1,000 in residual income for single applicants, with an additional $250 adjustment for each dependent beyond the first. VA loans have specific regional thresholds that range from $300 to $1,200 depending on location and family size.
How is corporate residual income different from net income?
Net income is the total profit after all expenses, while residual income subtracts a charge for the equity capital used to generate that profit. This provides a better measure of whether a company is creating value above its cost of capital.
Can I include annual bonuses in monthly gross income?
Yes, but divide the annual bonus by 12 to get the monthly equivalent. For irregular income, use an average of the past 12 months to get the most accurate residual income calculation.
Additional Guidance
Review your monthly expenses annually to identify areas where you can reduce costs and increase residual income. Small cuts to discretionary spending can add up to significant improvements in borrowing capacity over time.
For corporate calculations, update your cost of equity annually to reflect changes in market interest rates and company risk profile.
If your personal residual income is below lender thresholds, prioritize paying down high-interest recurring debt first to improve your debt-to-income ratio and residual income.
