Debt: borrowing money

A company borrows £100,000 from a bank to buy a new machine. The deal is plain. It will pay the bank £8,000 a year in interest, and one day pay back the £100,000. That £8,000 does not care what kind of year the company has. Record sales or a quiet slump, the bank gets £8,000. This is the whole character of debt, and once you see it, you understand half of how companies are financed.

What debt actually is

Debt is borrowed money you promise to pay back, with a fee for the use of it called interest, on a fixed schedule, whatever happens.

Notice the three hard words: fixed, schedule, whatever. The amount is set when you sign. The dates are set when you sign. And the duty to pay does not bend to your year. The bank does not become your partner. It does not share your risk. It hands over cash today and is owed a set stream of payments tomorrow, full stop.

Compare that to the owner’s slice from the start of this course. The owner is the residual claim — last in line, paid only what’s left in the glass after everyone else has drunk. Debt is the opposite kind of claim. It is a fixed claim: a set amount, paid before the owner sees a penny, and paid in full or not at all.

So the line you learned in item one now has a name at the front of it. Lenders stand ahead of owners. Interest is paid before owners keep anything.

The deal: cheap, but unforgiving

Why would a company ever take on a duty this rigid? Because it is cheap, and because all the upside stays with the owner.

It is cheap because the lender is taking less risk. They get paid first, and they get a fixed amount no matter how well things go. A safer, simpler claim costs less. So the interest a bank charges is usually lower than the return owners demand for standing at the back of the line. We’ll measure that gap properly in item seven; for now, hold the shape: borrowing money is the cheaper way to fund a company than selling ownership.

And the upside is all yours. The bank’s claim is fixed at £8,000. It does not rise when you have a wonderful year. If the machine you bought earns the company a fortune, the bank still gets £8,000 — and the owner keeps every extra pound. That is the bargain: pay a small fixed fee, keep all the gains above it.

But the bargain has a sharp edge. The claim is fixed both ways. It does not flex when you have a bad year either. A great year, you pay £8,000 and keep the rest. A bad year, you still owe £8,000 — even if it hurts, even if you have to take the money from savings to pay it. The bank’s £8,000 is the same number in a boom and a slump. That rigidity is not a flaw in the deal. It is the deal.

A worked year, good and bad

Hold the borrowing steady — £100,000 at 8%, so £8,000 of interest owed every year — and run two years through it.

The good year. The company’s operations earn £50,000 before interest (this is the operating profit — what the business makes from selling its goods, before the lender is paid). The bank’s claim comes first: pay £8,000. What’s left for the owners is £50,000 − £8,000 = £42,000. A fat leftover. The owner is delighted, and the bank is exactly as happy as it would be in any year — it got its £8,000.

The bad year. Sales sag. Operations earn just £2,000. But the bank’s claim has not moved. It is still £8,000. The company owes £8,000 and made only £2,000 from the business. It is £6,000 short. That gap doesn’t vanish because the year was hard. The company must find £6,000 from somewhere — its cash reserves, last year’s savings — to pay the bank in full. The owners get nothing this year, and they have to dip into the past to cover the shortfall.

Look at the two columns side by side. The bank received £8,000 in both years — the fixed claim did not flinch. The owners’ leftover swung from £42,000 to minus £6,000. All the variation in the year landed on the owner. None of it landed on the lender. That is what “fixed claim ahead of residual claim” means in pounds.

There is a single number where the year exactly covers the interest and no more. At £8,000 of operating profit, the company pays the bank £8,000 and the owners get £0. Above that line, every pound is the owner’s. Below it, the company is paying the bank out of money the business didn’t earn that year. That line — the point where operations just cover the fixed claim — is the edge debt makes you live near.

Where this sits in the whole

A fixed claim that must be paid whatever the year brings is not a banker’s trick. It is one of the oldest shapes in how humans share risk and reward. Someone wants safety and a steady return, and will take less for it. Someone else wants all the upside and will carry all the swing to get it. Debt is just that trade, written down with dates.

You are on both sides of it already. The mortgage on a house is this exact deal: a fixed payment owed every month, in a good year or a bad one, with the bank ahead of you and all the gain in the home’s value yours to keep. And the money sitting in your bank account does not sleep there — the bank lends it out, much of it to companies, as the fixed claims you’ve just watched. The £8,000 a firm pays its lender flows, through a long chain, toward the interest on ordinary people’s savings. You are a lender to companies without ever signing a thing. The rigidity that pins a firm to its £8,000 in a terrible year is the same rigidity that keeps a steady number landing in millions of accounts. The whole system runs on that fixed, unforgiving, deeply useful promise — and most of the people inside it never see which end they’re standing on.
