How the Calculator Works
Step 1: Enter your current cash position
Start with your Starting Balance — the amount of cash currently available in your business bank accounts.
Step 2: Estimate money coming in and going out
Add your expected Cash Inflows (sales, client payments, investments) and Cash Outflows (rent, payroll, operating costs) for the selected period.
Step 3: Choose a time frame and review your runway
Select Monthly or Quarterly to see how long your cash will last. The chart updates instantly, showing whether your balance is growing, stable, or declining over time.
Use this projection to identify cash gaps early — before they turn into funding or payroll problems.
Key Terms Explained
Starting Balance
The total cash your business has available today, including checking and savings accounts.
Cash Inflows
All money expected to enter your business during the period. This can include:
- Customer payments
- Accounts receivable collections
- Investment capital or loans
Accounts Receivable (AR)
Money owed to your business for goods or services already delivered but not yet paid for. In cash flow planning, AR only counts once you expect to actually receive the payment.
Cash Outflows
All expenses required to run your business, such as:
- Rent or mortgage
- Payroll and contractor payments
- Cost of Goods Sold (COGS)
- Software, marketing, and utilities
Operating Expenses
Recurring costs necessary to keep your business running, excluding one-time purchases or capital expenditures.
Cash Runway
The amount of time your business can continue operating before running out of cash, based on current inflows and outflows.
What Is a Cash Flow Projection?
A cash flow projection is a forward-looking estimate of how much cash your business will have over a specific period of time, based on expected inflows and outflows.
Unlike accounting reports that look backward, a cash flow projection answers a critical operational question:
“Will I have enough cash to keep the business running?”
Cash Flow Projection vs. Profit & Loss (P&L)
Many business owners assume that profitability equals financial health. In reality, businesses don’t fail because they aren’t profitable — they fail because they run out of cash.
Here’s the key difference:
- Profit & Loss (P&L)
Measures profitability on paper. It includes revenue earned and expenses incurred, even if no cash has actually changed hands yet. - Cash Flow Projection
Tracks real money moving in and out of your bank account, showing whether you can cover payroll, rent, and operating costs when they’re due.
For example, a business can show strong profits while still facing a cash crisis if customers pay late, inventory ties up cash, or expenses hit before revenue arrives.
Cash flow projections exist to prevent those surprises.
Why Every Small Business Needs a Cash Flow Projection
Cash flow is the lifeblood of your business. Without visibility into future cash positions, even growing companies can unknowingly drift toward insolvency.
Understanding Burn Rate
Your burn rate is how quickly your business is spending cash over time.
- A positive burn rate means you’re consuming cash faster than you’re generating it.
- A negative burn rate means your business is generating excess cash.
Tracking burn rate helps you answer questions like:
- How long can we operate at current spending levels?
- When will we need to raise capital or cut costs?
- How much runway do we have if revenue dips?
Without a projection, burn rate is invisible until it’s too late.
Avoiding Insolvency Before It Happens
Most cash crises don’t happen overnight. They build gradually through:
- Slow-paying customers
- Over-hiring
- Rising operating expenses
- Seasonal revenue drops
A cash flow projection surfaces these risks early, giving you time to:
- Adjust pricing or payment terms
- Reduce discretionary spending
- Delay hiring
- Secure financing proactively
In short, projections turn financial stress into manageable decisions.
The Cash Flow Projection Formula
At its core, cash flow forecasting follows a simple and transparent formula:
Ending Cash=Beginning Cash+Projected Inflows−Projected Outflows
Here’s how it works in practice:
- Beginning Cash
The cash currently available in your accounts. - Projected Inflows
Expected cash receipts, such as customer payments, investments, or loan proceeds. - Projected Outflows
Planned expenses, including payroll, rent, inventory, taxes, and operating costs.
Each period builds on the last. The ending cash balance becomes the beginning cash for the next period, creating a rolling forecast that reflects real business momentum.
This calculator automates that process and visualizes your cash runway — so you can spot problems early and plan with confidence.
Why This Matters
Cash flow projections aren’t just a financial exercise. They are a decision-making tool.
Businesses that monitor cash regularly:
- Make smarter hiring decisions
- Avoid emergency financing
- Negotiate better terms with vendors
- Sleep better knowing where they stand financially
If profit tells you whether your business works, cash flow tells you whether it survives.
