Convertible Debt Basics

Updated: Dec 3, 2020

Some startup and early-stage investments feature the “hybrid” security, a combination of debt & equity


By David M. Freedman and Matthew R. Nutting

When angel investors look at the financial statements of startups, they often find little or no history of profit or even positive cash flow. Without a solid track record, there wouldn’t be enough metrics on which to base a credible valuation, and it would thus be difficult to establish a fair price for shares of straight equity (stock or LLC units).

In many cases, issuers can avoid thorny disagreements over valuation by offering hybrid securities known as convertible notes to investors.

Starting as a Loan, No Valuation Necessary Whether issued by a corporation or an LLC, convertible debt starts out as a loan to the company from the investor, in the form of a note. This note can be traded back to the issuer, or converted, later for shares of stock or LLC units. Some convertible notes give investors the option to convert to equity, while others require investors to convert. Where conversion is required, typically the conversion is triggered on the occurrence of some specific future event that involves a valuation and/or transfer, such as a later round of equity financing or an acquisition.

When properly structured, convertible notes give investors the best of both worlds — liquidation preferences if the company becomes insolvent, capital gain if the company grows and gets acquired. It also presents an important advantage for issuers, especially startups that are pre-revenue, which we will explain.

The ultimate objective for investors, when they buy into the deal, is to end up with equity instead of debt.

Let’s Do Some Math The basic mechanics of convertible debt are easy to understand, but then the variables can get complex. Let’s say you invest $1,000 in Startup City, Inc., in an equity crowdfunding deal whereby the issuer promises to pay you x percent interest every month and then repay your principal in three years. If, at any point before the maturity date (within three years), a group of angel investors or a VC fund invests in Startup City, you have an opportunity to convert your $1,000 note, plus accrued interest if any, into Startup City stock. So far, the concept is simple. The fact that an angel or VC wants to buy stock means they believe the company has strong growth potential.

But how many shares will you receive for your $1,000? Looking at it another way, what is the price per share at the time of conversion? That is the primary question to be answered in the convertible note, which — like a term sheet for straight equity — lists all the terms of the investment. This is where it gets complicated.

The reason it’s complicated is that when you invested, the valuation of the company was not discussed. The valuation was probably very difficult to calculate at that time, because the company did not have enough revenue or other metrics to use as a basis for the calculation. And that is the beauty of convertible debt for entrepreneurs: The company can attract investors without having to propose or negotiate a valuation.

The deal you made when you invested did not specify a conversion price per share, because it was impossible at that time to forecast when another round of financing would occur, how well the company would perform in the meantime, and, thus, what price per share the later investors would agree to pay—and price is ultimately based on valuation.

The price per share that you (and other early, convertible-debt investors) pay to convert is derived from the price that later, straight-equity investors pay when they buy straight equity.

Discounts and Caps Let’s say this later round of investment comes two years after you invested, Startup City has become profitable, and the new investors agree to pay $1 per share of preferred stock, valuing the company at $4 million. Would you be satisfied paying $1 per share for 1,000 shares? Heck no! Early investors took a much greater risk, investing when the company was not yet profitable, than later investors. You should be rewarded for taking a big risk and providing seed capital to the company when it wasn’t so attractive to angel investors — not be penalized by having to pay as much for stock as the angels who waited until the investment wasn’t as risky. This fairness issue is typically resolved in one of two ways: discounts and caps.


  • Discounted convertible note. One way to reward early investors is by discounting the price that they must pay to convert when later investors buy stock. The convertible note states, in its list of terms, that you can convert debt to equity, in the event of a subsequent round of equity financing, at a discount that is typically 10 to 30 percent of what the new investors agree to pay per share. In the Startup City example, if you have a convertible note with a 20 percent discount, you would have an opportunity to convert to stock at 80 cents per share.

  • Convertible note with a cap. Another way to reward early investors is to cap the hypothetical valuation, on the basis of which the stock price is calculated for early investors who convert just before the subsequent round of equity financing. In our example, if your convertible note caps the valuation at $2 million, then you would pay half the price per share as the later investors who value Startup City at $4 million. Since the company was probably worth no more than $1 million when you invested, this seems like a fair deal.

The two terms can be combined in a discounted convertible note with a cap. But these discounts and caps have to be carefully planned, because if they are too advantageous to the investor, they could backfire for the company. If the discount is too high or the cap is too low, future angel investors — and especially VC funds — would balk at investing alongside crowdfunding investors who get inordinate bargains with the exact same rights, where the difference in valuations is remarkable. Alternatively, later equity investors will want a bargain, too.

One of the keys to a successful investment in convertible debt is assessing the possibility that the issuer will, if the business is successful, attract future rounds of straight-equity financing. Without that possibility, it’s just a loan.
