The Expensive Thing Is Often the Cheap One

There is a version of frugality that reliably costs money: always buying the cheap one.

The 40 coat that lasts a winter. The 15 pan that warps. The cheap boots replaced every year for a decade. Each individual decision looked sensible and the total was worse than buying properly once.

The arithmetic

cost per use = (price + running costs - resale) / total uses

A 200 coat worn 60 times a year for five years is 300 wears, so 67p a wear.

A 40 coat worn the same amount but lasting one year is 60 wears, so 67p a wear, and you buy five of them.

Identical. And that is with generous assumptions for the cheap one. Nudge the lifespan or the wear count slightly and the expensive coat wins clearly.

Where it genuinely changes decisions

Things you use constantly. A mattress used 2,500 times over seven years. A desk chair sat in daily. Shoes worn to work. Paying more is usually the cheaper choice and always the more comfortable one.

Things you use rarely. A carpet cleaner used twice a year, a tile saw, a roof box. Renting or borrowing is often dramatically cheaper, and storage is a cost most people never count.

Tools. The old advice to buy the cheap one and replace it with the good one when it breaks is a cost-per-use argument in disguise. It works because it defers the expensive decision until you know how much you will actually use the thing.

Subscriptions. Divide the annual cost by the number of times you actually opened it. This is frequently the most sobering calculation on the list, and the easiest to act on.

The problem with this calculation

It is trivially easy to abuse, and almost everyone abuses it in exactly the same way: by estimating uses from intention rather than history.

The 800 bike bought to cycle to work every day. The bread maker. The gym membership. The camera for the trip. Every one of them looks excellent at the imagined use count and absurd at the real one.

Use what you have actually done. If you cycled eleven times last year, put in eleven. The number will be uncomfortable and it will be correct, and it is a far better guide to the next purchase than optimism.

Most people find their estimates are optimistic by a factor of two or three. That pattern, once you know it about yourself, is worth more than any single calculation.

What it does not capture

Whether you needed it at all. A very low cost per use on something you did not need is not a saving. This compares options after you have decided to buy. It says nothing about the decision itself, and that is the decision that matters more.

Quality of experience. Two chairs at the same cost per use are not equivalent if one gives you back pain. Some of what you pay for is not durability.

Cash flow. The cheaper-per-use option usually costs more today. If paying 200 now means borrowing at 22%, the arithmetic changes completely and not in favour of the expensive coat.

Uncertainty. A five-year lifespan is a guess. Things get lost, broken, outgrown and superseded, and taste changes. The longer the assumed life, the more the calculation is really a forecast.

Resale changes the picture more than people expect

Money you get back was never really spent.

A 900 camera sold three years later for 500 cost 400 to own, not 900. A car that holds its value can be cheaper to own than a cheaper car that does not, which is the whole basis of depreciation-aware buying.

This is worth checking for anything with a real second-hand market: cars, bikes, cameras, tools, instruments, some furniture. It frequently reverses the answer.

A habit worth having

Before a significant purchase, write down the number of uses you expect. Put it somewhere you will find it.

Look again a year later.

You will learn your own bias, and correcting for it is more useful than any amount of general advice about spending. The cost per use calculator will handle the arithmetic and compare against a cheaper alternative over the same period, including how many uses the expensive one needs before it wins.

The honest version of frugality is not buying cheap. It is knowing what things actually cost.
