The “Discount Rate” in a Simple Agreement for Future Equity (SAFE) or similar investment instrument is a key term that benefits the investor. It represents a percentage reduction in the price per share that the investor will pay when their SAFE converts into equity upon certain triggering events, typically a future equity financing round or a qualifying transaction.

Let's break down how the Discount Rate works in the context of the statement you provided:

1. Future Equity Financing Round or Qualifying Transaction:

  1. The Discount Rate applies when specific triggering events occur. These triggering events typically include a future equity financing round, such as a Series A financing round, or a qualifying transaction, which could include an acquisition or IPO (Initial Public Offering).

2. Price Per Share Reduction:

  1. The Discount Rate represents a percentage reduction in the price per share of the company's equity securities that the investor will pay compared to the price paid by other investors in the same financing round or transaction.
  2. For example, if the company's equity securities are offered to new investors in the next financing round at a price of $1 per share, and the Discount Rate is 20%, the investor with the SAFE will purchase shares at a price of $0.80 per share.

3. Benefit to the Investor:

  1. The Discount Rate benefits the investor by providing them with a financial advantage when converting their SAFE into equity. It allows early investors to obtain shares at a lower cost than later investors in the same round, which can potentially result in a larger ownership stake for the same investment amount.

4. Illustrative Example:

  1. Suppose an investor invests $100,000 in a startup using a SAFE with a 20% Discount Rate.
  2. The company later conducts a Series A financing round, where new investors purchase shares at $1 per share.
  3. The investor with the SAFE will convert their investment into equity at a discounted price of $0.80 per share (20% less than $1 per share).

In summary, the Discount Rate in a SAFE is a mechanism that rewards early investors by allowing them to acquire equity shares in the startup at a lower cost per share compared to later investors in the same financing round or qualifying transaction. It encourages early-stage investment and provides a potential financial benefit to those who take on the risk of investing in a startup during its early stages.


To calculate the percentage of a company that an investor will receive when they invest $100,000 in a startup with a valuation cap of $5 million and a discount of 20%, you need to consider both the investment amount, the valuation cap, and the discount.

1. Calculate the discount amount:

Discount Amount = Investment Amount x Discount Rate

In this case, the investment amount is $100,000, and the discount rate is 20% (0.20):

Discount Amount = $100,000 x 0.20 = $20,000

2. Determine the effective valuation for the investor:

The effective valuation for the investor is calculated by subtracting the discount amount from the valuation cap:

Effective Valuation = Valuation Cap - Discount Amount

Effective Valuation = $5,000,000 - $20,000 = $4,980,000

3. Calculate the investor's ownership percentage:

Investor Ownership Percentage = Investment Amount / Effective Valuation

Investor Ownership Percentage = $100,000 / $4,980,000

Investor Ownership Percentage approx 0.02008

To express this as a percentage, multiply by 100:

Investor Ownership Percentage approx 2.008%

So, when the investor invests $100,000 in the startup with a valuation cap of $5 million and a 20% discount, they will receive approximately 2.008% ownership in the company.
