What Is Net Cash Flow?

Net cash flow is the total cash coming into your business minus the total cash going out in a given period—typically a week, month, or quarter. It tells you whether your cash position is growing or shrinking, and is the single most critical metric for business survival, because you can't pay bills with profit alone if the cash isn't there.

This is fundamentally different from profit. Profit measures revenue minus expenses on an accrual basis, where expenses and sales are recognized even if cash hasn't yet moved. Net cash flow measures the actual movement of money. A business can be profitable on paper yet run out of cash if it's not collecting from customers quickly enough or if it's holding excess inventory.

Formula

Net Cash Flow = Total Cash Inflows − Total Cash Outflows

Cash inflows include: customer payments, loans, owner investment, asset sales. Cash outflows include: payroll, supplier payments, loan repayments, tax payments, equipment purchases.

Example

A consulting firm received $50,000 in client payments this month, took out a $20,000 short-term loan, and paid $35,000 in salaries, $15,000 to suppliers, and $5,000 in rent. Net cash flow = ($50,000 + $20,000) − ($35,000 + $15,000 + $5,000) = $70,000 − $55,000 = +$15,000. Cash reserves grew by $15,000.

Tracking net cash flow weekly or daily helps you spot cash shortfalls before they force you to delay payments or make urgent decisions. Finmap automates this calculation and gives you a rolling view of your cash position so you can plan confidently.
