Is all debt bad?

No. Debt is a tool with a price, and the price is the interest rate. Borrowing at four percent for something that lasts thirty years is a different act from borrowing at twenty-four percent for something consumed last weekend. Judge the rate and what the money bought, not the word itself.

Two questions, not one

Treating debt as a single moral category is what keeps people stuck — either paralysed with guilt about a sensible mortgage, or relaxed about a credit card that is quietly eating them.

Two questions sort almost every case:

What is the rate? This is the price of the money, and it is not a small detail — it is the whole thing. At 3% a year, borrowing is close to free in real terms. At 24%, the debt roughly doubles every three years if left alone. These are not variations on a theme; they are different financial instruments that happen to share a name.

What did the money buy? Something that will still exist and still have value when the debt is repaid, or something that was gone before the first statement arrived?

The four combinations

Low rate, lasting thing. A mortgage on somewhere you will live for a decade. Debt doing its actual job: letting you have something now that you could not otherwise have for twenty years, at a modest price. Not a problem to be ashamed of.

Low rate, consumed thing. A cheap loan for a holiday. Not an emergency, but not a crisis — you are paying a small premium for having had it sooner. Fine occasionally, corrosive as a habit.

High rate, lasting thing. Expensive credit for a necessary appliance or car repair. Often unavoidable when there is no buffer, which is precisely the argument for building one. Clear it fast.

High rate, consumed thing. A credit card carrying restaurant meals from eighteen months ago at 24%. This is the one that does real damage, and it does it quietly — the spending felt small, the balance did not arrive all at once, and there is nothing left to show for it.

What makes debt genuinely dangerous

Beyond the rate, three things:

It compounds against you. The same mechanism that builds wealth slowly over decades destroys it just as reliably in the other direction, and consumer debt rates are far higher than realistic investment returns. You will never out-earn a 24% debt.

It reduces your options. Every fixed repayment is income already spoken for. Enough of them and you cannot leave a job, absorb a bad month, or take a risk — which is the actual cost, and it does not show up as a number anywhere.

It regrows. Debt cleared without a buffer behind it comes back with the next unexpected expense. That is why the order is buffer first, then debt, then buffer properly.

The useful reframe

Stop asking whether you have debt and start asking what it costs you each month in interest — an actual number.

Someone with a large mortgage at a low rate may be paying less for their borrowing than someone with a modest credit card balance. The size of the debt is not the burden. The price of it is.

Find that number for each debt. It will tell you immediately which ones are urgent and which are simply there.
