Estimate Business Cash Inflows, Outflows, and Ending Cash
Enter cash received and cash paid during the same weekly, monthly, quarterly, or annual period. All fields and results begin blank.
Cash Flow Inputs
Use figures from one consistent planning period.

Total inflows: Sales + financing + other incoming cash
Net cash flow: Total inflows − total outflows
Ending cash: Beginning cash + net cash flow
What Your Business Cash Flow Results Mean
Your results show how much cash entered the business, how much left, whether the period produced positive or negative cash flow, and how much cash may remain at the end.
Total Cash Inflows
Cash received during the period
This includes customer payments, cash sales, loans, owner contributions, and other money that actually entered the business during the selected period.
Total Cash Outflows
Cash paid during the period
This includes inventory, supplies, payroll, contractor payments, operating expenses, taxes, debt payments, and other amounts actually paid.
Net Cash Flow
Difference between incoming and outgoing cash
Positive net cash flow means more cash entered than left. Negative net cash flow means the business used more cash than it generated during the period.
Projected Ending Cash
Estimated cash remaining at period end
Ending cash combines the beginning balance with the period’s net cash flow. It indicates whether the business may finish with available cash or a projected shortage.
Inflow-to-Outflow Ratio
Cash received compared with cash paid
A ratio above 1.00 means inflows exceeded outflows. A ratio below 1.00 means outflows exceeded inflows during the selected period.
Cash Flow Status
Quick interpretation of the result
The status summarizes whether cash flow is positive, balanced, negative while cash remains, or expected to result in a shortage.
Positive Cash Flow Does Not Always Mean High Profit
Borrowed money and owner contributions increase cash but do not represent operating profit. Review cash flow together with profit margin, debt, and recurring operating performance.
Timing Can Change the Result
A customer payment arriving one day later or a large supplier bill being paid earlier can materially change the period’s ending cash. Use actual payment dates whenever possible.
Three Business Cash Flow Scenarios
These examples show how the same business can experience positive cash flow, temporary negative cash flow, or a projected cash shortage depending on payment timing and spending.
Positive Monthly Cash Flow
A service business collects customer payments faster than it pays payroll, operating costs, and taxes.
Inventory Purchase Creates Negative Flow
A retailer buys seasonal inventory before the related customer sales are collected.
Projected Cash Shortfall
A new business experiences slower collections while payroll, rent, loan payments, and other costs remain due.
A single negative period does not always signal a failing business. Seasonal inventory purchases, tax payments, annual insurance premiums, equipment purchases, and delayed customer collections can temporarily reduce cash. The key is whether the business has enough liquidity to cover the gap.
What This Calculator Helps You Plan
Test changes in collections, expenses, financing, inventory, payroll, and payment timing to see how each assumption affects net cash flow and projected ending cash.
Earlier vs. Later Collections
See how receiving customer payments sooner or later changes available cash during the planning period.
Try changing: Sales and customer payments.Normal vs. Heavy Inventory Buying
Compare a routine purchasing month with a period that includes seasonal or expansion-related inventory spending.
Try changing: Inventory and supplies.Current vs. Expanded Payroll
Estimate how hiring employees, adding contractor hours, or increasing owner compensation affects liquidity.
Try changing: Payroll and contractor payments.Self-Funded vs. Financed Growth
Compare available cash when growth is supported by current operations, owner funding, or borrowed money.
Try changing: Loan or owner contributions.Routine vs. High-Expense Periods
Test months that include annual insurance, tax payments, equipment costs, repairs, or other irregular expenses.
Try changing: Operating and other payments.Low vs. Strong Cash Reserves
Compare how much beginning cash is needed to absorb a temporary negative-flow period without creating a shortage.
Try changing: Beginning cash balance.Compare Timing, Not Just Totals
The same annual revenue and expenses can produce very different cash-flow results depending on when customers pay and when bills are due.

Business Cash Flow Calculator FAQs
These answers explain cash inflows, cash outflows, net cash flow, ending cash, liquidity, payment timing, and how to use the calculator when reviewing business cash needs.
What is business cash flow?
Business cash flow is the movement of money into and out of the business. Positive cash flow means more cash entered than left during the period, while negative cash flow means the business used more cash than it received.
What should I include as a cash inflow?
Include money actually received during the period, such as cash sales, customer payments, loans, owner contributions, refunds, grants, and other incoming funds.
What should I include as a cash outflow?
Include amounts actually paid, including inventory, supplies, payroll, contractor payments, rent, software, utilities, taxes, loan payments, equipment purchases, and other operating costs.
What is the difference between cash flow and profit?
Profit compares revenue and expenses under accounting rules. Cash flow measures when money is actually received and paid. A profitable business can still experience a cash shortage if customer payments arrive late.
What does a negative cash flow result mean?
Negative cash flow means cash outflows exceeded inflows during the selected period. It may be temporary, but repeated negative periods can reduce reserves and eventually create a funding shortfall.
Is borrowing considered positive cash flow?
Borrowed money increases available cash and appears as a cash inflow, but it is not operating profit. Future principal and interest payments will create cash outflows.
How much ending cash should a business keep?
The appropriate reserve depends on fixed expenses, payment timing, seasonality, credit access, supplier terms, and risk. Many owners aim to maintain enough cash to cover several weeks or months of essential costs.
How often should I review business cash flow?
Review cash flow at least monthly, and more frequently when collections are irregular, reserves are limited, expenses are changing, or the business is growing quickly.
Planning Checkpoint
Do not wait for the bank balance to become critically low before reviewing cash flow. Compare expected collections, required payments, reserves, financing access, and upcoming irregular expenses early enough to make practical adjustments.
