Business Cash Flow Calculator
Why You Need This Calculator
Many business owners focus on profit but neglect cash flow. Profit is an accounting concept; cash flow is what pays your bills. A business can be profitable on paper but still run out of cash if expenses are front-loaded or customers delay payments. Our calculator reveals your true monthly cash position, helping you plan for lean times and invest in growth opportunities.

How the Calculator Works
You input:
- Monthly Revenue – total income from sales.
- Cost of Goods Sold (COGS) – direct costs of producing your product or service.
- Operating Expenses – rent, salaries, utilities, marketing, etc.
- Monthly Tax Provision – set aside for taxes.
- Cash Reserves – your current cash on hand.
- Months to Project – how far forward you want to project (default 12).
The calculator then computes:
- Gross Profit – revenue minus COGS.
- Gross Margin – gross profit as a percentage of revenue.
- Net Cash Flow – revenue minus all expenses (including taxes).
- Net Margin – net cash flow as a percentage of revenue.
- Break-Even Revenue – the revenue level needed to cover all expenses (net cash flow = 0).
- Runway – how many months your cash reserves will last if net cash flow remains negative.
- Projected Cash After N Months – your expected cash balance after the projection period.
It also displays a doughnut chart showing the breakdown of expenses and a line chart projecting your cash balance month by month.
Example: Sarah’s E-commerce Business
Sarah runs an online store. Her monthly revenue is $50,000, COGS $20,000, operating expenses $15,000, taxes $5,000, and she has $100,000 in cash reserves. She wants to project for 12 months.
- Gross Profit = $50,000 – $20,000 = $30,000
- Gross Margin = 60%
- Net Cash Flow = $50,000 – $20,000 – $15,000 – $5,000 = $10,000
- Net Margin = 20%
- Break-Even Revenue = $40,000 (she needs at least this much to break even)
- Runway = N/A (positive cash flow)
- Projected Cash After 12 Months = $100,000 + ($10,000 × 12) = $220,000
Sarah sees that her business is healthy, generating $10,000 per month in extra cash. She can plan to reinvest in inventory or marketing.
Real-World Case Study: Mike’s Restaurant
Mike owns a restaurant. His monthly revenue is $30,000, COGS $12,000, operating expenses $20,000, taxes $3,000, and he has $25,000 in cash reserves. He’s worried about cash flow.
- Gross Profit = $18,000
- Gross Margin = 60%
- Net Cash Flow = $30,000 – $12,000 – $20,000 – $3,000 = -$5,000
- Net Margin = -16.7%
- Break-Even Revenue = $35,000 (he needs $5,000 more per month to break even)
- Runway = ceil($25,000 / $5,000) = 5 months
- Projected Cash After 12 Months = $25,000 + (-$5,000 × 12) = -$35,000 (will run out of cash in 5 months)
The calculator warns Mike that his cash flow is negative and his runway is only 5 months. He needs to increase revenue or cut expenses immediately. This insight is critical for his survival.
Why Break-Even Revenue Matters
Your break-even revenue is the minimum sales you need to cover all costs. If your revenue falls below this, you’re losing money. Our calculator computes this automatically, so you can set sales targets and pricing strategies accordingly. Many business owners don’t know their break-even point – this tool reveals it instantly.
