Are Cash Flow and Profit the Same?

Are cash flow and profit the same?

They answer different questions. Profit asks, "Did the business earn more than it spent over this period?" Cash flow asks, "How much money came in and went out, and what is the balance now?"

Both start from the same activity, which is why they get confused. A sale is a sale whether the customer pays today or weeks later. Profit counts the sale when you earn it. Cash flow counts it when the money lands.

Here is the short version side by side.

If your books use accrual accounting, profit follows the "earned and incurred" rule in the table. If your books use cash accounting, profit and cash flow sit much closer together, but they still part ways on loan principal, owner draws and equipment. Ask whoever keeps your books which method you use. If you want the statements themselves explained, start with how to read a profit and loss statement.

Profit vs cash flow example

Here is a made-up business to show the gap. These numbers are invented for illustration only.

Example (illustrative numbers only): a small design studio in one month.

The studio looks healthy on the profit and loss statement and is still short of cash. Nothing is wrong with the work. The invoices have not been paid yet, the equipment was paid for up front, and loan principal is not an expense.

That is a common pattern in profitable businesses that run short of cash. Money is tied up in what customers owe you, what you hold in stock, and what you spent on assets. Profit shows the earning. Cash shows what you can actually spend.

Why is cash flow more important than profit?

It is not always more important, but it is more urgent. Payroll, rent, suppliers and loan payments are paid in cash, not in profit. A business can survive a quiet quarter with thin profit if it has cash. It will struggle badly without cash to pay people, however good the profit looks on paper.

At the same time, profit over several periods tells you whether the business model works. A business that burns cash for years and never makes a profit is relying on someone else's money. So the useful answer is that you watch both, for different jobs:

• Profit tells you whether the business is worth running, and whether prices cover costs.
• Cash flow tells you whether you can pay what is due next week, next month and next quarter.

What makes profit and cash flow drift apart?

Most gaps come from a short list of causes. When your numbers do not match your bank balance, check these first.

1. Customers who pay late. Unpaid invoices are counted in profit and missing from cash. This is a very common cause.
2. Bills you have not paid yet. The reverse effect: the expense is in profit, the money is still in your account. This flatters your bank balance for a while.
3. Inventory. Stock you buy sits as an asset until you sell it. Cash goes out at purchase; the cost hits profit only when the goods are sold.
4. Equipment and other assets. You pay at purchase; the cost reaches profit gradually through depreciation, which is a non-cash charge.
5. Loan principal. Repaying the principal of a loan reduces cash and does not appear as an expense. Interest does.
6. Owner draws and distributions. Money you take out is not an expense of the business, but it leaves the bank.
7. Deposits and prepayments. A customer paying you in advance brings in cash before you have earned the revenue. You paying a supplier in advance does the reverse.
8. Sales tax and payroll taxes collected. These sit in your bank account for a period but belong to someone else. Cash looks higher than it really is.

The third and fourth causes explain why a growing business so often runs short of cash. Growth means more stock, more receivables and more equipment, all of which absorb cash before they produce profit.

Where does each number come from in your books?

Three reports show the picture, and they need to agree with each other.

• The profit and loss statement gives profit. See how to read a profit and loss statement.
• The balance sheet shows the cash balance, what customers owe you and what you owe. See how to read a balance sheet.
• The cash flow statement reconciles the two by showing why cash changed. See what is a cash flow statement.

If these reports are built from books that are behind or not reconciled, the gap between profit and cash becomes hard to explain. That is where a monthly bookkeeping routine matters: bank accounts reconciled, receivables and payables kept current, so every number can be traced.

How do you track both without a finance degree?

You do not need a model. A monthly routine covers most of it.

1. Look at profit for the month and for the year to date.
2. Look at the actual cash balance, not just the profit.
3. Look at the unpaid invoices list and the unpaid bills list.
4. Compare profit with the change in cash and write down why they differ, using the list above.
5. Compare actual results with your plan. Budget vs actual is the usual way to do it.

Step 4 is the one most owners skip, and it is the one that stops surprises. If the gap grows month after month, find out which cause is driving it before you make decisions based on profit alone.

Where each view wins and loses

Profit wins when you are judging pricing, margins and whether the business model works. It smooths out timing so one late payment does not distort the month. It loses as a short-term safety measure, because it can look fine while the bank balance runs out. Related reading: what is gross margin.

Cash flow wins when you are deciding whether you can pay for something now, hire someone, or take on stock. It loses as a judge of whether the business is worth running, because one large customer payment or a loan can make a month look wonderful when the underlying earnings are poor.

A plain way to think about it: neither number is the "real" one. Treat profit as the scorecard and cash as the fuel gauge.

When this is not for you

You may not need to dig into this if you run a very simple business that is paid at the point of sale, holds no stock and buys little equipment. In that case profit and cash will sit close together and your bank balance is a decent guide. You also do not need a controller to read two statements. If you already have a bookkeeper who explains the gap each month, you may be fine.

It becomes worth getting help when the gap is large and unexplained, when you carry stock or long payment terms, or when you are planning a hire, a loan or a big purchase. English Oak's fractional controller service includes cash management and cash-flow monitoring on a monthly reporting cycle. We start at $1,500 a month for controller work (custom, one fixed monthly fee), and you can see how pricing works on the pricing page or in what we do.
