Financial projections are a key part of any startup’s business plan, showing investors and lenders how you’ll make money and grow. They’re also a valuable planning tool, helping you anticipate cash needs and make informed decisions. Creating realistic financial projections takes research and careful thinking, but it’s worth it.

Here’s how to create financial projections for your startup.

Step 1: Create a Revenue Projection

Start by projecting your revenue. Be realistic—base it on market research, industry benchmarks, and your business model.

How to Project Revenue:

  • For product-based businesses: Estimate number of units sold × price per unit
  • For service-based businesses: Estimate number of clients × hourly rate or project fee
  • Consider growth rate: Project how revenue will grow month over month or quarter over quarter

Step 2: Create an Expense Projection

Next, project your expenses: fixed expenses, variable expenses, and one-time expenses.

Common Expenses to Include:

  • Fixed expenses: rent, salaries, insurance, software subscriptions
  • Variable expenses: COGS, materials, sales commissions, marketing
  • One-time expenses: equipment, legal fees, website development

Step 3: Create a Profit and Loss (Income Statement) Projection

Combine your revenue and expense projections to create a profit and loss projection, showing your projected profit or loss over time, usually 3-5 years.

Step 4: Create a Cash Flow Projection

Cash flow is critical for startups—create a cash flow projection showing when money comes in and goes out. This helps you anticipate cash shortages and plan for them.

Step 5: Create a Balance Sheet Projection

Create a balance sheet projection showing your assets, liabilities, and equity at a point in time.

Step 6: Use Realistic Assumptions

The key to good financial projections is realistic assumptions. Document your assumptions clearly, so investors understand how you got your numbers.

Key Assumptions to Document:

  • Growth rate
  • Customer acquisition cost
  • Average order value
  • Churn rate (for subscription businesses)
  • Operating expenses
