# What Is Margin (Debt)?

> In debt finance, margin is the spread above a reference rate—such as SOFR—that a borrower pays on a loan, expressed in basis points as the lender's pricing for credit risk.

**Margin (debt)** is the interest spread a borrower pays above a benchmark reference rate on a floating-rate loan, typically quoted in basis points.

### How it works

Most corporate and venture debt uses floating rates: **All-in rate ≈ Base rate + Margin**. The base rate might be SOFR (successor to LIBOR) or a prime rate. Margin compensates the lender for credit risk, illiquidity, and structure complexity.

Example: SOFR at 4.5% plus a 650 bps (6.5%) margin yields roughly 11% cash interest before fees. Loan agreements often include a **floor** on the base rate so margin does not collapse when rates fall.

Venture debt margins vary with stage, revenue quality, and warrant coverage. Buyout senior debt may price at lower margins with stronger collateral; mezzanine layers charge higher margins or PIK components.

Margin differs from **profit margin** in operating metrics—context matters in finance conversations.

### Why it matters

- **Founders:** A low margin with heavy warrants and tight covenants may cost more over time than a higher margin with flexibility. Model total cost of capital.
- **Investors:** Rising base rates pass through to borrowers unless hedged; margin is the negotiable piece reflecting company-specific risk.

### Common mistake

Quoting only margin in term sheets without the current base rate and floor. Investors and boards want all-in interest and PIK components for comparison.

## FAQ

### What is margin in debt in simple terms?

It is the extra interest on top of the benchmark rate. If SOFR is 5% and your margin is 7%, you pay about 12% all-in on a floating-rate loan—subject to floors and fees.

### Why does margin matter?

Margin reflects lender risk pricing. Higher margins mean tighter covenants or weaker credit. Founders comparing term sheets should look at margin, fees, warrants, and covenants together—not headline rate alone.
