Venture Debt vs Equity: When Should a Startup Borrow?

Venture debt is the right choice when a startup has just raised equity and needs more runway to hit a milestone that will raise its next valuation. It dilutes far less than equity, because the lender takes warrants instead of shares, but it must be repaid on a fixed schedule and comes with covenants. Equity is the safer choice when repayment depends on hope.

This guide is general information, not financial or legal advice. Loan terms vary widely by lender and by company, and your counsel and finance lead should model any term sheet against your actual plan.

What Is Venture Debt?

Venture debt is a term loan made to a venture-backed startup, underwritten mainly on the strength of its equity investors rather than its cash flow or collateral. A bank lends against assets and earnings. A venture lender lends against the likelihood that your investors will fund the next round.

That is why venture debt is almost always drawn after an equity round, not instead of one. The lender reads a fresh round as proof that sophisticated investors priced the company and backed it with cash. Mercury's venture debt term sheet guide puts typical loan size at 20–50% of the previous venture round, so a $5 million Series A supports roughly $1–2.5 million of debt.

Venture debt has three moving parts:

How Does Venture Debt Compare to Equity?

Equity costs ownership and never has to be repaid; venture debt costs cash flow and must be repaid on schedule whether or not the plan works. That one difference drives every other trade-off.

A warrant, as the SEC's Investor.gov glossary explains, gives its holder the right to buy shares at a set price before an expiration date. For a lender, that is the upside kicker. For a founder, it is the only dilution venture debt creates.

What Are Typical Venture Debt Terms in 2026?

Most venture term loans have an interest-only period of about a year, a total term of three to five years, a variable rate tied to prime, and warrant coverage that rises as covenants get lighter. Mercury's guide gives these ranges:

Those are one lender's published ranges, not market standards. Treat them as a starting point for negotiation.

Variable rates move with the market. The prime rate is published in the Federal Reserve's H.15 selected interest rates release, and some lenders price off the Secured Overnight Financing Rate, which the New York Fed publishes daily. If your model assumes today's rate for four years, also run it with the rate two points higher.

Expect fees beyond interest. Many term sheets include an upfront fee, a final payment due at maturity and a prepayment fee if you repay early. Ask the lender to express every fee in dollars on your actual loan, not just as a percentage.

What Does Venture Debt Actually Cost?

The true cost of venture debt is total interest plus fees plus the value of the warrants — and it should be compared with the dilution of raising the same cash as equity. Here is an illustrative scenario, not a real loan or quote.

A company raises a $12 million Series A at a $30 million post-money valuation. It then takes a $3 million loan at a 12% variable rate, with 12 months interest-only and 36 months of amortization, plus warrant coverage of 10% of the loan.

Raising the same $3 million as equity at the same $30 million post-money would cost about 10% of the company. So in this example, debt costs roughly a tenth of the dilution — in exchange for about $900,000 in interest and a fixed monthly obligation that peaks above $100,000.

That trade is excellent if the extra runway gets the company to a milestone that doubles its valuation. It is dangerous if revenue slips and the company spends its last six months paying down a loan instead of building.

When Should a Startup Take Venture Debt?

Take venture debt when it is cheap insurance on a plan that already works: right after an equity round, with predictable revenue or burn, and with a specific milestone the extra months will buy. The test is whether you could repay it if the next round never came.

What Covenants and Clauses Should Founders Watch?

The interest rate matters less than the clauses that let a lender declare a default and accelerate the loan. A covenant is a promise in the loan agreement; breaking one can make the whole balance due.

Read these clauses first:

Deposit requirements became a live issue in March 2023. Silicon Valley Bank, a major venture lender that required many borrowers to bank with it, failed on March 10, 2023. The Federal Reserve's review of its supervision of SVB documents how concentrated and uninsured its deposits were. The lesson for borrowers: negotiate the right to keep operating cash with more than one institution.

What Are the Alternatives to Venture Debt?

If neither a priced round nor a term loan fits, founders usually choose between an extension of the last round, a convertible instrument, or revenue-linked financing.

For priced equity, most U.S. venture rounds start from the NVCA model legal documents, which define the preferred stock terms that debt sits ahead of.

How Do You Decide Between Debt and Equity?

Run four checks in order; if any one fails, raise equity instead.

If all four pass, venture debt is often the cheapest capital available in ownership terms. If any fails, the dilution of equity is the price of not having a creditor ahead of your shareholders.

Frequently Asked Questions

Is venture debt cheaper than equity?

In ownership, usually yes: lenders take warrants worth a small fraction of the company, while equity costs the full percentage sold. In cash, no: venture debt carries interest, fees and fixed repayments. It is cheaper only if the company can comfortably make the payments and the extra runway raises its next valuation.

How much venture debt can a startup raise?

Most venture loans are sized relative to the last equity round. Mercury, which offers venture debt, puts typical loan size at 20–50% of the previous venture round. The final amount depends on the lender, your investors, your revenue and your burn rate.

When is the best time to take venture debt?

The best time is shortly after closing an equity round, when your runway is long and your investors have just priced the company. Lenders offer better terms then, and you have time to use the loan as planned. Borrowing when cash is nearly gone weakens your negotiating position and raises default risk.

What happens if a startup cannot repay venture debt?

If a startup misses payments or breaks a covenant, the lender can declare a default and demand the full balance. Because most venture loans are secured by company assets, the lender is repaid before shareholders in a wind-down or sale. In practice, lenders often negotiate a restructuring, but on their terms.

Do venture lenders take board seats?

Venture lenders typically do not take board seats or voting control. Their influence comes from covenants, default rights and security over company assets. That leverage can matter more than a board vote when cash runs short.
