Cash flow

Clear, simple guide to cash flow: what it is, why it matters, how to read a cash flow statement, common types, key metrics, and practical tips to improve cash flow for businesses and individuals.

What is cash flow

Cash flow is the movement of money into and out of a business or a personal account. It shows actual cash that you can spend, not profits on paper. When more cash comes in than goes out, you have positive cash flow. When more goes out than comes in, you have negative cash flow.

Think of cash flow like water in a bucket. Income fills the bucket. Expenses drain it. If the drain is bigger than the faucet, the bucket will empty.

Why cash flow matters

Profit and cash are not the same. A company can report profits but still run out of cash. That happens when sales are recorded but customers have not paid yet. Cash flow is what pays bills, payroll, rent, and suppliers. Without steady cash flow, a business can fail even if it looks profitable.

For individuals, cash flow affects the ability to pay bills, save, and invest.

Three main types of cash flow

Understanding each type helps you read the cash flow statement.

  • Cash flow from operating activities

    • Money from selling goods or services.
    • Includes cash paid to suppliers, wages, taxes.
    • It shows the cash generated by the core business.

  • Cash flow from investing activities

    • Cash spent or received from buying or selling long-term assets.
    • Examples: buying equipment, selling a building, investments in other companies.

  • Cash flow from financing activities

    • Cash from borrowing, repaying loans, issuing stock, or paying dividends.
    • It shows how the business funds itself.

The sum of these three gives the net change in cash for a period.

The cash flow statement in plain terms

The cash flow statement is a financial report that lists the three types above. It starts with the cash at the beginning of the period and ends with cash at the end. Main steps:

  1. Start with net income if using indirect method.
  2. Add noncash expenses like depreciation.
  3. Adjust for changes in working capital like inventory or payables.
  4. Add cash from investing and financing.
  5. Get net change in cash.

The direct method lists actual cash receipts and payments. The indirect method adjusts net income. Both give the same final cash amount.

Key cash flow metrics

  • Net cash flow: total cash in minus cash out over a time period.
  • Operating cash flow (OCF): cash from core operations.
  • Free cash flow (FCF): operating cash flow minus capital expenditures. It shows cash available after keeping the business running.
  • Cash flow margin: operating cash flow divided by sales. It shows how well sales turn into cash.
  • Cash conversion cycle: days inventory sits, plus days sales outstanding, minus days payable outstanding. Shorter is better.

How to improve cash flow

Small changes can make a big difference.

  • Speed up collections

    • Invoice promptly.
    • Offer a small discount for early payment.
    • Use electronic payments and reminders.

  • Manage inventory

    • Keep less stock.
    • Use just-in-time or reorder points.

  • Control expenses

    • Cut or delay nonessential spending.
    • Negotiate better terms with suppliers.

  • Stretch payables carefully

    • Pay on the last day of terms without hurting relationships.
    • Negotiate longer payment terms.

  • Use financing wisely

    • Short-term lines of credit can bridge gaps.
    • Avoid using long-term funds for short-term needs.

Common mistakes

  • Confusing profit with cash. Sales recorded do not mean cash received.
  • Letting customers slip on payments without follow up.
  • Holding too much inventory.
  • Ignoring seasonal swings. Some months need cash reserves.
  • Relying solely on loans instead of fixing the underlying cash issues.

Simple example

A small shop sells $10,000 of goods in a month. But customers pay only $7,000 that month. The shop also pays $6,000 in rent, wages, and supplies. Net income might still be positive on paper. Cash flow is $7,000 in minus $6,000 out equals $1,000. If accounts receivable rise, next month cash could drop even if sales stay high.

Quick checklist for business owners

  • Do you have a cash flow forecast for the next 90 days?
  • Are invoices issued the same day an order ships?
  • Do you know your days sales outstanding?
  • Can you cut nonessential spending quickly if needed?
  • Do you have a line of credit for emergencies?
