What is a Capital Stack?
The Capital Stack represents the hierarchy of financing sources used to fund a company, real estate project, or investment venture. It outlines the order of claims on assets and cash flows, from the safest (senior debt) to the riskiest (common equity).
Definition
The Capital Stack is the structured layers of capital (debt and equity) that define who gets paid first and who bears the most risk in an investment.
Key Takeaways
- Defines priority of payments and claims in a business or project.
- Lower layers (debt) have lower risk and lower return; upper layers (equity) have higher risk and higher return.
- Guides investor expectations, risk allocation, and financing strategy.
Understanding the Capital Stack
The capital stack helps investors understand how capital is structured and how returns are distributed. Each layer has different rights, risks, and expected returns.
The typical capital stack includes:
- Senior Debt
- Lowest risk, first to be repaid.
- Secured by assets, lowest interest rates.
- Mezzanine Debt
- Higher risk than senior debt, may include equity warrants.
- Higher interest rates.
- Preferred Equity
- Priority over common equity in receiving dividends or distributions.
- Often has fixed or contractual returns.
- Common Equity
- Highest risk, lowest priority in repayment.
- Highest potential return if the investment succeeds.
The capital stack influences negotiations, investor protections, and exit strategies.
Formula (If Applicable)
There is no single formula for the capital stack, but return calculations differ across layers:
- Debt: Fixed interest payments
- Preferred Equity: Contractual distributions
- Common Equity: Residual profits (Return = (Exit Value − Investment) / Investment)
Real-World Example
A real estate development project may use:
- $50M Senior Debt
- $10M Mezzanine Debt
- $15M Preferred Equity
- $25M Common Equity
If the project performs well, senior debt is repaid first, followed by mezzanine investors, then preferred equity holders. Common equity owners receive remaining profits.
Importance in Business or Economics
Understanding the capital stack is essential for:
- Assessing investment risk

Capital stacks also help align incentives among lenders, investors, and operators.
Types or Variations
