For startups, understanding numbers is not just “nice to have” – it is essential. Mastering financial terms like ROI, ROAS, Working Capital, Profit Margin, COGS, and EBITDA will give you a clearer view of your financial health and keep your startup company on the path to profitability. Knowing these formulas will also help you in your Pitch Deck. Let’s break down these critical financial metrics in an approachable, easy-to-understand way.
1. ROI (Return on Investment): Gauging Your Financial Success
Return on Investment (ROI) is a crucial metric for assessing how effective your investments are at generating profit. Knowing your ROI lets you see which ventures are worth your time and resources and which aren’t.
Formula for ROI:
Example: If you invested $10,000 in a marketing campaign and it brought in $15,000 in revenue, your net profit would be $5,000, making your ROI 50%. This percentage is a reliable way to measure the efficiency of your startup’s financial decisions.
2. ROAS (Return on Ad Spend): Evaluating Your Marketing Efficiency
Return on Ad Spend (ROAS) helps you understand how effectively your advertising budget translates into revenue. For startups, marketing dollars are precious, so a good ROAS ensures that each ad dollar is pulling its weight.
Formula for ROAS:
Example: If you spent $2,000 on an ad campaign and generated $8,000 in revenue, your ROAS is 4. This means you earned $4 for every dollar spent. High ROAS values are a good sign that your advertising efforts are paying off.

3. Working Capital: Fueling Daily Operations
Working Capital is the lifeblood of a startup’s daily operations. It’s the difference between what you own and what you owe in the short term. This figure ensures that you have enough funds to manage expenses like salaries, supplies, and rent without running into cash flow issues.
Formula for Working Capital:
Example: If your startup has $20,000 in current assets and $12,000 in current liabilities, your working capital would be $8,000. A positive working capital figure indicates that your startup has enough to cover its short-term expenses.
4. Profit Margin: Tracking Financial Efficiency
Profit Margin shows how much profit your startup makes from its total revenue, giving insight into your pricing and cost control. A high-profit margin means your startup is good at turning revenue into actual profit.
Formula for Profit Margin:
Example: If your startup made $50,000 in revenue and has a net profit of $15,000, the profit margin is 30%. This percentage tells investors and stakeholders that you’re efficiently converting revenue into profit.
5. COGS (Cost of Goods Sold): Knowing What it Costs to Deliver
Cost of Goods Sold (COGS) measures the direct costs incurred in producing your product or service. COGS doesn’t include indirect expenses like rent or marketing, making it ideal for determining how much it costs to deliver your product or service.
Formula for COGS:
Example: If you start with an inventory valued at $5,000, make $10,000 in purchases, and end with $4,000 in inventory, your COGS is $11,000. COGS plays a vital role in setting product prices and tracking gross profit.
6. EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization): Evaluating Core Profitability
EBITDA provides a clear view of your startup’s profitability by stripping away interest, taxes, depreciation, and amortization costs. It focuses on operational performance, making it ideal for understanding a startup’s core financial health.
Formula for EBITDA:
Example: If your startup has a net income of $25,000, with $3,000 in interest, $2,000 in taxes, $4,000 in depreciation, and $1,000 in amortization, your EBITDA would be $35,000. EBITDA is a great indicator of operating efficiency, especially for startups looking to attract investors.
7. Cash Flow: Managing the Lifeline of Your Business
Cash flow is a straightforward yet crucial metric that tracks how cash moves in and out of your business. For startups, positive cash flow ensures you’re covering expenses and investing in growth, while negative cash flow can signal potential financial challenges.
Formula for Cash Flow:
Example: If your startup receives $20,000 in revenue (inflows) and spends $15,000 (outflows) on operations, your cash flow is $5,000. Consistently positive cash flow keeps your startup financially flexible and resilient.
8. Burn Rate: Keeping Track of Financial Sustainability
Burn Rate tells you how quickly your startup is spending its cash reserves. For early-stage startups and stealth startups, knowing your burn rate can prevent unexpected financial shortfalls and help secure funding.
Formula for Burn Rate:
Example: If your startup has $100,000 in reserves and monthly expenses of $20,000, your burn rate is 5 months. Monitoring burn rate helps plan for sustainable growth and, when necessary, pivot to stay on track.
9. Break-Even Point: Setting Milestones for Profitability
The break-even point is where your startup covers all expenses and starts generating profit. Knowing your break-even point is crucial to setting realistic sales goals and planning financial sustainability.
Formula for Break-Even Point (in Units):
Example: With fixed costs of $10,000, a product price of $50, and variable costs of $30, you’d need to sell 500 units to break even. This calculation guides your strategy to cover costs and move toward profitability.
