Discounted Cash Flow Calculator (DCF)

Last updated: Nov 03, 2020

This discounted cash flow calculator (or DCF calculator for short) provides you with a simple method of company valuation. With just a few clicks, you will be able to estimate how much a startup is worth and whether it makes sense to invest in it.

If you're not sure how to calculate the discounted cash flow or what it is, make sure to scroll down for a detailed explanation, including the DCF formula.

If your early-stage startup doesn't bring any profit yet, check out our break even calculator instead!

What is DCF?

The discounted cash flow (DCF) is a method of company valuation, usually used for late-stage startups. It is mostly applied by investors to check whether their investment will bring substantial profit.

The principle of the discounted cash flow is very similar to the Net Present Value (NPV). The calculation consists of a few steps:

  • First of all, you have to project cash flows for the next couple of years. It is usually done by estimating the growth rate of the company - for example, you assume that each year will bring a 15% increase in the company value.

  • In the second step, the cash flow estimates are discounted using an annual discount rate. This calculation reflects the change in the value of your money. Consider this example: $100 today is not an equivalent of $100 in three years from now - after all, you could put it in a savings account, where its value would steadily increase. The discount rate is usually assumed to be equal to WACC (Weighted Average Cost of Capital).

  • In the next step, you need to estimate the terminal value of your company. Usually, you won't assume that your startup grows at a steady rate for infinity. Instead, you have to assume a lower growth rate, called the terminal growth rate, to show that growth is slowing down. Basing on that number, you will estimate the increase in your company's value from the end of the growth phase to the end of the startup's existence.

  • Finally, the result (called the total intrinsic value) has to be compared with the amount of money you want to invest. If the intrinsic value is higher, it means that the returns from the investment exceed the costs. If, on the other hand, the intrinsic value is lower, the investment will (most likely) never pay off.

Discounted cash flow formula

Now that you understand the principle of DCF valuation, it's high time to introduce the DCF formula!

The total intrinsic value consists of two parts:

intrinsic value = growth value + terminal value

The growth value describes how your company's value will increase during the growth stage. You can calculate it with the following equation:

growth value = EPS * A * (1 - Aⁿ) / (1 - A)


  • EPS are the earnings per share,
  • A is a coefficient equal to A = (1 + g) / (1 + r),
  • g is the growth rate,
  • r is the discount rate (equal to WACC), and
  • n is the number of years when your startup is growing at a growth rate g.

The other part of the intrinsic value, called the terminal value, can be found with the following formula:

terminal value = EPS * Aⁿ * B * (1 - Bⁱ) / (1 - B)


  • EPS are the earnings per share,
  • A is a coefficient equal to A = (1 + g) / (1 + r),
  • g is the growth rate,
  • r is the discount rate (equal to WACC),
  • n is the number of years when your startup is growing at the growth rate g,
  • B is a coefficient equal to B = (1 + t) / (1 + r),
  • t is the terminal growth rate, and
  • i is the number of years in terminal growth.

How to calculate the discounted cash flow: an example

Uff, that was a lot of formulas! Let's look at an example to understand the principles governing the DCF valuation.

You are an investor and want to buy shares in a startup, paying $300 per share. During the last 12 months, the startup's earnings per share were at a level of $50. Will your investment pay off?

  1. The first thing you do is ask the startup about their projected growth. The CEO is confident that they will be able to achieve stable growth of 8% annually for the next five years.

  2. The next step is the evaluation of the terminal growth. After some research, you assume that a terminal growth rate of 3% over the following five years seems realistic.

  3. Last but not least, you check the average values of WACC and decide to choose 11% as the discount rate.

  4. Once you know all of these values, all you need to do is plug them into the discounted cash flow formulas:

A = (1 + g) / (1 + r) = (1 + 0.08) / (1 + 0.11) = 0.973

B = (1 + t) / (1 + r) = (1 + 0.03) / (1 + 0.11) = 0.928

growth value = EPS * A * (1 - Aⁿ) / (1 - A) = $50 * 0.973 * (1 - 0.973⁵) / (1 - 0.973) = $230.45

terminal value = EPS * Aⁿ * B * (1 - Bⁱ) / (1 - B) = $50 * 0.973⁵ * 0.928 * (1 - 0.928⁵) / (1 - 0.928) = $175.15

  1. Finally, sum up the growth value and terminal value:

intrinsic value = growth value + terminal value = $230.45 + $175.15 = $405.60

The intrinsic value, equal to $405.60, is higher than the amount you wanted to invest ($300). Theoretically, it means that the investment will pay off in the end. If you look more closely, though, you will notice that the growth value is lower than $300! It means that after five years, the investment will still not bring a profit. If you don't mind such a long-term investment, then it's not a problem. If you do - well, maybe other options will bring profit much faster...
