Starting a new business comes with mixed emotions; it can be both daunting and exciting at the same time. You are finally doing something you believe in, with the potential of making an impact, and maybe making some money at it. However, while doing something you believe in is exciting, running a startup also comes with daunting tasks; one of them being financial modelling. You need to create this model to have a financial forecast for your startup’s future performance.
To get started, you first need to create financial model assumptions that drive the projections of your cash flow, revenue, and earnings. These determine how viable the rest of your financial model is. Below, we explore how to choose assumptions for your financial model.
Let’s pick a business to make this easier. Say you’re starting a pastry shop called Dee’s Nook. It’s the cutest pastry shop on one of the busiest streets in your city. You would sell the most heavenly baked goods; the smell would waft into the streets and remind people of their grandma’s baked goods. The UK Bakery market is a £3.6 billion industry. So why not jump in?
Superb idea. However, before you go on, you need to make quite a few assumptions about your business to build a financial model. They include revenue and expense assumptions mainly. We explain them below:
1. Revenue Assumptions
A great way to fill the assumption tab is to start by filling in what you believe to be the most accurate representations of the revenue you hope to receive. This will help you make feasible financial forecasts.
- How many baked goods do you project you’ll sell per day every year?
- What’s the average price of the baked goods you’ll sell?
2. Expense Assumptions
These are assumptions you make about the cost of your business. They include direct and indirect .
For Dee’s Nook, you would have to answer questions like the following:
- What is the cost of the ingredients you need? For example, how much does it cost to buy flour, sugar, butter, etc.?
- How many baked goods will the ingredients yield?
- How much do you cost time and labor?
- What’s the average rent you would pay?
- How much more would you pay for utilities such as electricity and heating?
- Don’t forget tax! How much would you need to pay for tax?
- Would you be paying for any baking equipment upfront?
- What other costs are you paying to be able to run my business smoothly? For example, are you providing perks such as free WiFi? How much would you be spending on that?
3. Other Assumptions
You can input other assumptions that do not fall under the above. For example, for Dee’s Nook, you can identify some of the relevant assumptions by answering the following questions:
- How many working days are there in a year?
- Will you be catering events as well as selling baked goods to retail customers?
- Are there peak periods in the year for selling baked goods? Will seasonal variance affect sales?
Choosing Assumptions for Non-Existing Businesses
Now, it might be easier to create assumptions for a bakery or some other ‘brick-and-mortar’ business that already exists somewhere. Then, you can pop into a few bakeries, buy a donut (or a dozen), and just sit and watch how the business works.
However, if your startup idea is a business that does not precisely exist yet, you would need to do a bit more research into businesses that offer similar services or products. This is called benchmarking. You can also use your historical data if you are already selling the product/service before creating your financial model.
Another great way to go about this is to make range assumptions instead of point assumptions. So, instead of saying Revolutionary Product A will cost £200 and you will make ten sales every day, your assumptions can say Revolutionary Product A will cost £200 – £250, and you will make 5 – 10 sales daily.
