Cash Flow Analysis Steps and Key Metrics

Cash flow analysis explains why your cash position changed over a certain period, helping teams tell the difference between normal business activity and problems that need attention, like late payments or unexpected spending. This way, you can see if the business can cover its bills and keep investing without putting extra strain on cash.

A good analysis also points out which payments, investments, or funding choices need a closer look. It highlights cash movements that need action, shows which assumptions may need to be updated, and explains how different situations could change your cash levels.

In this blog, we’ll walk you through how to analyze cash flow, track key metrics, spot important differences, and improve your cash planning.

Cash flow analysis sorts cash movements into operating, investing, and financing activities. This separates cash from daily operations from cash used for investments and funding. It also matches the structure in IAS 7 Statement of Cash Flows.

Together, these categories show how cash changes over a reporting period:

Operating cash flow covers cash generated and spent through core business activities. It includes customer payments, supplier payments, payroll, taxes, and other operating expenses.

This category shows whether regular business activities bring in enough cash to cover ongoing needs. For example, a distributor might sell more but see operating cash flow drop if customers pay more slowly or inventory purchases increase.

Investing cash flow covers purchases and sales of long-term assets. It usually includes CAPEX, equipment purchases, property investments, acquisitions, and proceeds from asset sales.

Negative investing cash flow does not always mean the business is doing poorly. For example, a manufacturer might spend money on a new production line to boost capacity. Still, the company should check how this affects cash and whether operating cash flow can cover the investment.

Financing cash flow shows how the company raises and repays capital. It includes new loans, debt repayments, equity contributions, dividends, and similar transactions.

This category helps explain changes in debt and available cash. For example, a company might have positive operating cash flow but see its cash balance drop after repaying a large loan or paying dividends.

Teams should review all three categories together. Deciding how to classify some transactions may require judgment, since IFRS and US GAAP sometimes treat them differently, as shown in KPMG’s comparison of cash flow reporting requirements.

A good cash flow analysis relies on accurate data, clear categories, variance checks, and updated assumptions.

First, choose a time period that fits your decision. Weekly views are helpful for short-term cash needs, monthly views support management reports, and quarterly views reveal bigger cash trends and funding needs.

Many companies use more than one time frame. For example, a 13-week cash view tracks near-term collections and payments, while a monthly forecast shows the expected year-end balance.

The level of detail should match the time period. Weekly analysis might track each customer payment, payroll date, tax deadline, and large supplier invoice. Monthly analysis usually groups these into broader cash flow categories.

Next, gather data from the general ledger, bank accounts, accounts receivable and payable, payroll, tax schedules, CAPEX plans, and loan schedules.

In addition to invoice dates, the data should also reflect expected payment dates. For instance, a customer invoice due in 60 days should not appear as an immediate cash inflow. The same rule applies to supplier payments and debt repayments.

Teams should also make sure all sources use the same reporting period, currency, and company structure. Otherwise, there could be duplicate transactions, missing payments, or old balances. A quick data check before starting saves time later.

Then, place each cash movement into the right category: operating, investing, or financing. You can also separate regular items from one-time transactions. This prevents a major asset purchase or loan repayment from distorting the view of daily operations.

For more detail, teams can add extra categories. Operating cash flow might include customer payments, supplier payments, payroll, taxes, and other expenses. Investing cash flow can split maintenance CAPEX from growth CAPEX, and financing cash flow can separate new loans from repayments and dividends.

Next, compare actual results to the budget or most recent forecast. Look at both the total cash position and the main factors driving cash flow.

For example, customer collections may fall below plan even when sales reach the target. Inventory purchases may also exceed the forecast because production increased or procurement ordered materials earlier than planned.

The comparison should show both the amount and timing of each difference. A payment might still happen, just a week or two later than planned. That delay can create short-term pressure even if the yearly forecast stays the same.

Then, figure out what caused the biggest differences. Focus on items that clearly affect cash flow.

Common causes include:

• late customer payments
• higher inventory purchases
• early supplier payments
• unplanned CAPEX
• changes in tax payments
• new debt or debt repayments

Each difference should have someone responsible and a next step. For example, the sales team might follow up on overdue invoices, while procurement might delay non-essential purchases.

Finally, update the cash forecast with the latest information. Adjust expected collection dates, supplier payments, payroll, taxes, CAPEX, and financing as needed.

The updated forecast should show both confirmed changes and reasonable estimates. For example, if a major customer pays late, move the expected cash inflow to the new date. If a CAPEX project starts later, shift those payments too.

This step turns the analysis into a planning tool. The team can see how changes now might affect cash in the coming weeks or months. They can then try actions like delaying purchases, changing payment schedules, or using credit lines.

The right metrics help teams measure cash generation, working capital efficiency, and how reliable forecasts are. They also make it easier to spot changes that need a closer look.

Free cash flow shows how much cash is left after the company pays for capital expenses.

For example, a manufacturing company may generate €12 million in operating cash flow and spend €7 million on equipment. Its free cash flow equals €5 million.

Free cash flow helps show if the business can repay debt, pay dividends, or invest more without needing extra financing.

Operating cash flow margin shows how much operating cash the company makes from each euro of revenue.

If a distributor reports €100 million in revenue and €8 million in operating cash flow, its operating cash flow margin equals 8%.

Teams should compare the margin over several periods. If revenue goes up but the margin drops, receivables, inventory, or operating costs might be using more cash.

The cash conversion cycle measures how long cash is tied up in receivables and inventory before the company collects it from customers.

A longer cycle can mean slower collections, too much inventory, or shorter supplier payment terms. A shorter cycle usually helps liquidity because the company collects cash faster or keeps less stock.

Cash flow variance shows the gap between expected and actual cash flow.

If these differences keep happening, it may mean the forecast uses unrealistic collection dates, old purchasing plans, or incomplete CAPEX assumptions.

Teams can track how accurate forecasts are by looking at how large and how often these differences occur. They should also check which categories and assumptions caused them.

A good cash flow analysis does more than explain past changes. It should show what changed, why it happened, and what actions to take next.

The table below connects common analysis issues with the decisions they should support.

Each important difference should have a clear explanation, someone responsible, and a next step. This turns cash flow analysis from just reporting into a useful tool for payment planning, working capital control, investment decisions, and short-term funding.
