Starting your business can be exciting, but to run it successfully you need good financial planning. A Financial Model for Your Startup serves a bigger purpose than a spreadsheet, as it guides the economic direction of your company. With a budget, you can predict your income, guess your spending, plan how much cash you’ll have and know if you’re making a profit.

These are the main components that a solid Financial Model for Your Startup should have:

• COGS refers to the cost of the products sold by a company.

It describes the costs that go straight into delivering your product or service.

• Operating Expenses (OPEX) is the third main category of company costs.

Such expenses comprise salaries, marketing, legal costs, rent and administrative fees.

• Capital Expenditure or CapEx.

Trading for things that will benefit the company in the months or years to come such as software, machines or infrastructure.

• The success or failure of a business is carefully monitored through its P&L Statement 

This shows the balance of revenues against all expenses to get net profit.

• Financial Balance Sheet

Reports the assets, liabilities and equity of your company as of a certain date.

• Statement of Cash Flows

Monitors cash flow in and out of your business month by month.

4.1 Define Your Assumptions

• Customer Acquisition Cost (CAC)
• Lifetime Value (LTV)
• Conversion rates
• Pricing models
• Monthly Churn Rate

These assumptions power every calculation in your Financial Model for Your Startup.

4.2 Project Revenue

Define your revenue drivers:

• Units sold per month
• Monthly recurring revenue (MRR)
• Year-over-year (YoY) growth rates

Create monthly projections for each revenue stream.

4.3 Identify Costs and Expenses

Categorize your spending:

• Fixed Costs: Salaries, office rent, insurance

Ensure you match these with revenue timings for accurate cash flow forecasts.

4.5 Develop the Cash Flow Statement

Use real-world timing of cash movement:

• Tax obligations

Ensure you forecast monthly for at least 18-24 months.

Thinking about different situations

Envision what the situation could be like in three ways.

• Most likely: The expected results
• The best case scenario shows steady and widespread growth throughout the world.
• In the worst situation, growth maps take more time and are more costly to set up and maintain.

Sensitivity analysis.

See if changes to the system make a big difference in the model.

• CAC variations
• More people are leaving the company.
• Delayed revenue

It makes your startup’s Financial Model more reliable.

7. Errors to Beware of

Some of the economic models used today make unrealistic assumptions.

Unless you can show that there is demand for your product, don’t promise huge monthly growth.

Being Unaware of How Weather Changes

Remember that sales can be higher during particular seasons and drops when trends are low.

Overestimating your Profit

Expenses that aren’t obvious such as subscriptions, insurance and taxes, continue to increase.

There is no version control present in the system.

You should keep every model you create to notice how your approach improved over time.

Aim to avoid doing these things so your Financial Model for Your Startup comes across as valid.

8. Apply the fundraising model when making decisions and strategies.

Having a great financial model is crucial for presenting your idea in the pitch deck. It helps:

• Show how the operation can be expanded and still make a profit
• Prove you are aware of the needs of your customers.
• Support the way you have valued the company.
• Setup how you will spend the funds you have invested

Your Financial Model should be properly laid out and you should consider including dashboards where required.

9. Upgrading and Keeping the Model Current

A financial model shifts and develops with time.

Monthly updates 

Check the results against what was expected to make the information more accurate.

KPI Tracking

Watch the following metrics:

• Burn rate
• CAC means Customer Acquisition Cost and LTV is Lifetime Value.
• Revenue growth

Look at the whole chain from beginning to end

Get advice from advisors or CFOs to enhance your Financial Model for Your Startup.
