Managing cash flow is one of the most critical aspects of running a business in Illinois. Whether you're a small business owner in Chicago or operating statewide, knowing how money moves through your business is pivotal to your long-term success.
Our Business Cash Flow Calculator (below) helps you quickly estimate your cash inflows, outflows, and net cash position, enabling you to make smarter financial decisions.
The Three Components: How Our Cash Flow Calculator Works
Cash flow is calculated using a straightforward formula with three key components: cash inflows, cash outflows, and net cash flow.
Cash Inflows
Cash inflows represent all money coming into your business during a specific period. This includes:
- Revenue from sales
- Accounts receivable collected
- Loans or lines of credit
- Investment income
- Grants or government incentives (common in Illinois business programs)
Example: If your business earns $50,000 in monthly revenue and collects $5,000 in outstanding invoices, your total inflow is $55,000.
Cash Outflows
Cash outflows include all expenses needed to operate your business:
- Rent or lease payments (especially high in metro areas like Chicago)
- Payroll and employee benefits
- Inventory and supplies
- Utilities and insurance
- State and local taxes (Illinois has a 4.95% individual income tax and a 9.5% combined corporate tax rate for C corporations as of 2026)
Example: If your monthly expenses total $42,000, that's your total outflow.
Net Cash Flow
Net cash flow is the difference between inflows and outflows:
Formula: Net Cash Flow = Cash Inflows − Cash Outflows
Complete example:
- Cash Inflows: $55,000
- Cash Outflows: $42,000
- Net Cash Flow: $13,000
When the number is positive, it means your business is financially healthy. A negative number signals potential cash shortages that need immediate attention.
