Debt Financing
How Debt Financing Works
A company borrows a set amount from a lender (bank, bond investors, or private credit fund) and agrees to repay it according to a defined schedule. The agreement specifies the interest rate (fixed or floating), maturity date, repayment structure (amortizing or bullet), and covenants the borrower must maintain.
Interest payments are tax-deductible, which makes debt cheaper on an after-tax basis compared to equity financing. This tax benefit is one of the main reasons companies use debt in their capital structure.
Types of Debt Financing
| Type | Description | Typical Users |
|---|---|---|
| Term Loan | Lump-sum loan repaid on a fixed amortization schedule | Companies of all sizes for capex, acquisitions, refinancing |
| Revolving Credit Facility | Flexible credit line — draw, repay, and re-borrow up to a limit | Corporates for working capital and liquidity |
| Bonds | Debt securities sold to investors in public or private markets | Large corporates and governments |
| Bridge Loan | Short-term financing to “bridge” until permanent funding is secured | M&A deals, real estate transactions |
| Mezzanine Debt | Hybrid debt that sits between senior debt and equity, often with warrants | LBOs, growth-stage companies |
| Subordinated Debt | Junior to senior lenders — higher risk, higher yield | Leveraged transactions |
| Commercial Paper | Short-term unsecured promissory notes (< 270 days) | Investment-grade corporates for short-term needs |
Debt Financing vs. Equity Financing
| Feature | Debt Financing | Equity Financing |
|---|---|---|
| Ownership | No ownership given up | Investors gain ownership stake |
| Repayment | Must repay principal + interest | No repayment obligation |
| Tax Benefit | Interest is tax-deductible | Dividends are not tax-deductible |
| Cost | Lower (senior in capital structure, tax shield) | Higher (equity risk premium) |
| Risk to Company | Default risk if payments are missed | No default risk |
| Control | Retained by existing owners | Shared with new shareholders |
| Availability | Requires cash flow and/or collateral | Available even to pre-revenue startups |
Advantages of Debt Financing
No dilution. The company keeps 100 % of its ownership. If the business triples in value, the lender still only gets their interest — all the upside belongs to the owners.
Tax shield. Interest payments reduce taxable income. At a 25 % tax rate, a 6 % interest rate effectively costs only 4.5 % after taxes.
Predictable cost. Fixed-rate debt locks in the cost of capital. The company knows exactly what it owes regardless of future performance.
Lower cost of capital. Debt is cheaper than equity because lenders take less risk — they’re paid before shareholders in a liquidation and have contractual claim on payments.
Disadvantages of Debt Financing
Fixed obligations. Interest and principal payments are due regardless of whether the business is profitable. Missing a payment can trigger default.
Covenants and restrictions. Covenants may limit the company’s ability to take on more debt, pay dividends, make acquisitions, or sell assets.
Bankruptcy risk. Too much leverage amplifies downside risk. If cash flows decline, the company may not be able to service its debt, leading to restructuring or liquidation.
The Tax Shield in Practice
A company paying 5 % interest with a 25 % tax rate has an effective after-tax cost of 3.75 %. This is why the WACC formula uses the after-tax cost of debt — the tax shield makes debt significantly cheaper than its headline rate.
Debt Financing on Financial Statements
Borrowed amounts appear as liabilities on the balance sheet — current portion in current liabilities, the rest in long-term debt. Interest expense reduces operating profit on the income statement. Borrowings and repayments flow through the financing section of the cash flow statement.
Key Takeaways
- Debt financing means borrowing money that must be repaid with interest — no ownership is given up.
- The tax deductibility of interest makes debt cheaper than equity on an after-tax basis.
- Common forms include term loans, revolving credit facilities, bonds, and mezzanine debt.
- The main risks are fixed payment obligations, covenant restrictions, and bankruptcy if leverage gets too high.
- Use the interest coverage ratio and debt-to-equity ratio to assess whether a company’s debt load is sustainable.
Frequently Asked Questions
What is debt financing in simple terms?
Debt financing means borrowing money that you promise to pay back over time with interest. The lender doesn’t become an owner — they just get their money back plus a return.
Why do companies prefer debt over equity?
Debt is cheaper because interest is tax-deductible and lenders accept lower returns (they take less risk). Plus, the company keeps 100 % ownership — there’s no dilution.
What happens if a company can’t repay its debt?
Missing debt payments triggers a default. The lender can demand immediate repayment, seize collateral, or force the company into restructuring or bankruptcy proceedings.
Is debt financing risky?
It adds financial risk because payments are mandatory regardless of business performance. Moderate debt enhances returns through leverage, but too much debt can push a company toward insolvency during a downturn.
What is the difference between secured and unsecured debt?
Secured debt is backed by specific collateral (property, equipment, receivables) that the lender can seize if the borrower defaults. Unsecured debt has no collateral — lenders rely solely on the borrower’s creditworthiness, so they charge a higher interest rate to compensate for the added risk.
