How Does My Convertible Note Discount Stack With the Valuation Cap?

You raised your first funding through a convertible note. The terms looked straightforward. Your investors received a 20% discount and a valuation cap, and everyone agreed to move forward.

Now your Series A is approaching.

Your lawyer explains that the convertible notes will convert into equity before the new investors receive their shares. Suddenly, you’re trying to calculate how much of your company those early investments will own.

Many founders assume the discount and valuation cap work together to give investors an even better deal. They don’t.

At conversion, investors receive whichever option gives them the lower price per share. Understanding how these two provisions work can help founders estimate dilution more accurately and avoid surprises during a priced financing.

Why Convertible Notes Include Discounts and Valuation Caps

Convertible notes reward early investors for taking additional risk before a company’s valuation has been established.

Two of the most common investor protections are the discount and the valuation cap.

Although both affect the conversion price, they serve different purposes.

The discount rewards investors for investing early, while the valuation cap protects them if the company’s value increases significantly before the next financing round.

How the Discount Works

The discount allows note holders to purchase shares at a lower price than the new investors participating in the priced round.

For example, if your Series A investors pay $5.00 per share and your convertible note includes a 20% discount, the note converts at $4.00 per share.

This lower price means the early investor receives more shares for the same investment amount.

The discount is simply a reward for accepting greater risk before the company completed a priced financing.

What the Valuation Cap Does

The valuation cap protects early investors when a startup grows much faster than expected.

Instead of converting at the high valuation negotiated during the priced round, the note converts as though the company were worth no more than the agreed valuation cap.

For example, if your note has a $5 million valuation cap but your Series A is priced at a $10 million pre-money valuation, the note holder converts using the lower $5 million valuation.

Because the conversion price is lower, the investor receives more shares.

The Discount and Cap Do Not Work Together

One of the most common misconceptions is that investors receive both the discount and the valuation cap at the same time.

That is not how convertible notes typically work.

At conversion, both calculations are performed separately.

The investor simply chooses the option that produces the lower conversion price, because that results in more shares.

Founders should always calculate both outcomes before estimating post-financing ownership.

A Simple Example

Assume a founder issued:

• A $25,000 convertible note
• A $5 million valuation cap
• A 20% discount

Later, the company raises a Series A at a $10 million pre-money valuation, with new investors purchasing shares for $5.00 per share.

Using the discount, the conversion price becomes $4.00 per share.

Using the valuation cap, the conversion price becomes $2.50 per share.

Because $2.50 is the lower price, the valuation cap applies.

The $25,000 note converts into 10,000 shares, which would be worth $50,000 at the Series A price.

This example illustrates why founders should model note conversions carefully before negotiating a priced round.

Why This Matters During Fundraising

Convertible notes affect more than the early investors. Their conversion also changes the founder’s ownership percentage.

Many founders focus only on the percentage being purchased by the new Series A investors and overlook the shares created when outstanding notes convert.

Both events happen as part of the same financing.

If note conversions are not included in your capitalization model, your actual post-closing ownership may be lower than expected.

Running these calculations before signing the term sheet provides a more accurate picture of founder dilution and helps avoid surprises at closing.

Common Founder Mistakes

• Assuming the discount and valuation cap are added together: These provisions do not stack. The investor receives whichever calculation produces the lower conversion price and therefore the greater number of shares.
• Agreeing to a valuation cap without modeling different financing scenarios: A cap may have little effect in a lower-priced round but can significantly increase dilution if the next financing is completed well above the cap.
• Ignoring note conversions when reviewing the Series A ownership percentages: Founder dilution comes from both the new investment and the shares issued when outstanding notes convert.
• Failing to calculate post-financing ownership before signing the term sheet: Understanding how every outstanding note converts allows founders to negotiate with a clear picture of their future ownership.

10-Minute Convertible Note Self Check

• Do I know the discount and valuation cap for every outstanding convertible note?
• Have I calculated both the discount conversion price and the valuation cap conversion price?
• Do I know which calculation produces the lower share price?
• Have I modeled note conversions at my expected Series A valuation?
• Have I included both note conversions and new investor shares in my post-financing cap table?
• Can I explain my expected dilution to my co-founders and existing investors?

If you cannot answer yes to all of these, you are not ready to close your priced round yet.

Bottom Line

Convertible note discounts and valuation caps are designed to reward early investors, but they do not operate together. At conversion, investors receive whichever method provides the lower price per share. Founders who model both calculations before a priced financing gain a much clearer understanding of dilution, ownership, and the true impact of their outstanding convertible notes.
