Startup Cash Flow: Your First Forecast In 20 min. [spreadsheet inside]

Tell me the truth: have you already built a cash flow forecast for your startup?

Hum… probably you’re just waiting a little bit more…because you have so many things to do…

But, I bet you are postponing it because you think it is:

a) Boring;
b) Complex;
c) Useless in the beginning;
d) All of the above.

I know many startup founders struggle to build their first cash flow forecast. But, if you’re serious about building a successful business, you can’t just ignore it.

WHY? Many reasons…

  1. Cash is king: without cash, everything ends. It won’t matter how many visitors you have or if you’re profitable or not. If your startup doesn’t have cash, it’s over. So, you need to wisely manage your cash flow since day 1.
  2. Forecasting is understanding: when you build the first cash flow forecast for your startup, you’ll start understanding basic principles of your business. What are your revenue streams? How much do you need to sell to produce a positive cash flow? How much are you able to invest? Etc…
  3. Well-informed decisions: a great cash flow forecast will make most of your key decisions clearer. Is investment “X” worth? Hiring someone for a higher salary is sustainable? How a sales commission affect my cash flow?
  4. Your investors will love it: if you’re thinking of getting money from investors, having a cash flow forecast will help you on showing them you know what you’re doing. A great founder knows what he/she will do with the money and how that will impact his/her startup’s cash flow.

In the following paragraphs, I’ll guide you through the steps of building your cash flow forecast using the spreadsheet.

Step 1: Finding The Fields

To insert your startup’s information, the first thing you need to do is to open the hidden fields.

Just click on the “+” signs that are above and in the left of the spreadsheet.

Find the fields to fill in your cash flow forecast

Form Columns “B” to “G”, is where you’ll insert the information about your startup’s cash flow.

The cells you'll fill in to generate you cash flow forecast.

Step 2: Inserting The Info

Now, it’s time to input your startup’s information in the right fields.

You’ll find 4 big categories: “Fund Raising”, “Revenue”, “Costs & Expenses” and “Investments”.

Now, it’s when the magic starts to happen. The spreadsheet will automatically generate the flow, as soon as you’ve inserted the information.

An example of a cash flow forecast with some information.


In this first category, you’ll fill in the information regarding your fundraising sources. Here you have the following fields:

  • Source (blank cells): the source of your funding. E.g.: partners, family members, friends, angel investor, seed funds, loans, etc.
  • Amount ($): the amount of money the source provided to your startup.
  • M/Y (Month/Year): the month/year you expect funds to become available for your startup.

For example, if you and your partner will invest $30,000 each, in January, 2020, then you’ll have:

"Fund Raising" fields.


Now, it’s time to forecast the revenue flow you expect to receive from your customers. Fields:

  • Product/Service Name (blank cells): for each line insert the name of a product or a service your startup will sell;
  • Type: select among three types of revenue: “SaaS”, “Sales” and “Commission” (% of volume). The model will generate the flow based on the type you’ve selected.
  • Price/%: how much you’ll charge for 1 unit of your product or, in the case of “Commission”, the percentage you’ll charge as a fee (%).
  • Volume: the volume of items you expect to sell in the first month of revenue. For “Commission” type it is the volume on which the fee will be calculated.
  • Starts In: the first month you expect receiving revenue for each product.
  • Increase (%): the monthly increase you expect your revenue will grow (if you let it blank, no increase will be considered)

For example, if you are working with a SaaS revenue model and you intend to sell a $40 subscription, expect start selling 100 subscriptions in Apr-2020, with a monthly increase of 1%. Here is what you should inform:

"Revenue" fields.


For this category, you’ll find three different sections:

% OF REVENUE: You’ll use this section for any cost that is dependable on your revenue. E.g.: taxes, sales commission, COGS, etc.

For instance, if, in your country, any revenue is taxed in 15%, you should insert:

"% of Revenue" fields on the cash flow forecast.

FLAT + ANUAL RAISE: You should include in this section any cost or expense that have a regular flow. This costs will happen whether you have revenue or not. E.g.: Salaries, rent, energy, services, subscriptions, etc.

For example, you contracted office rent for $1,500/month and expect a raise of 5% in oct-2020:

"Flat + Annual Raise" fields on the cash flow forecast.

SPORADIC/CUSTOM: In this last section, you may include any cost or expense that the flow doesn’t fit properly to the above categories. E.g.: an expense with an irregular flow.

For instance, you have a 3-month service from jan-2020 to mar-2020, with a variable amount. In this case, you’ll need to insert the amounts directly in the cash flow area:

"Sporadic/Custom" fields on the cash flow forecast.


Here, you’ll insert the investments you plan to do in the next 24 months. E.g.: marketing campaigns, new equipment, app development, etc.

For instance, if you have hired a third party to build your MVP, for $30,000, divided into 6 installments, starting in January-2020, you’ll inform:

"Investments" fields on the cash flow forecast.

Step 3: Generating Insights

Okay, as soon as you include your startup’s information, the spreadsheet will generate the flow. That’s awesome, isn’t it?

But, you know what is even more awesome? The insights you’ll gain from the flow to better drive your decisions..

These insights are presented in two different types of metrics: NET METRICS and GROSS METRICS.


The metrics you see here reflect the outcome of every item you’ve estimated in your forecast (Fund Raising, Revenue, Costs & Expenses, and Investments):

Example of Net Metrics.


These metrics don’t take into account the revenue nor the costs associated with it. In other words, if you fail generating revenue in the next two years, how bad would that be?

Example of Gross Metrics.

So, dear founder, I hope by now you have generated your first cash flow and have a better understanding about your business.
