Work out what your clothes really cost to wear

If you want to know what a garment really costs you, the simplest useful answer is this: add up what you actually spend on it, then divide that by how many times you actually wear it. That gives you a clothing cost per wear figure you can compare across items in your wardrobe.

Used properly, it is a practical decision tool, not a moral badge. It can help us spot the jeans we live in, the coat that earns its place, and the bargain that turned out not to be one. It is less useful when we use it to excuse buying something expensive on the hope that we might wear it constantly, or to make sweeping claims about sustainability without looking at care, repair and real use.

What cost per wear can tell you and what it cannot

The basic formula is straightforward:

Total known cost of the garment ÷ number of wears = cost per wear

If a shirt costs £40, needs £12 of sleeve shortening, and you wear it 52 times, the cost per wear is £1.

That is useful because it shifts the question from "Was this cheap?" to "Was this useful to me?" A £12 top worn twice costs more per wear than a £60 jumper worn weekly for two winters. For everyday wardrobe planning, that is often the more honest comparison.

It also helps with buying decisions before we spend. If we know we already wear navy cardigans constantly and rarely reach for fitted blazers, the likely cost per wear of those categories will be very different. We do not need a perfect capsule wardrobe to learn from that. We just need to notice patterns.

What it cannot do is prove that an item was worth any price we felt like paying. A low forecast cost per wear is not permission to overspend. "If I wear this 200 times it will only cost pennies" is still a guess at the point of purchase. Sometimes the fabric annoys us, the fit shifts after washing, or the item simply does not suit our real life.

It also cannot carry vague sustainability claims on its own. A garment worn often may well make better use of the resources already spent on it, but cost per wear is not a full environmental assessment. It does not tell us how fibres were produced, how workers were treated, how the item was dyed, or what happens at end of life. In the UK, as in the EU, broad environmental claims in marketing are under increasing scrutiny, and rightly so. For our own wardrobe decisions, it is better to keep the measure modest and honest. It tells us about use and value to us. It does not tell the whole story.

What to include before you divide the total

The most common mistake is dividing the ticket price by an optimistic number of wears and calling it done. If we want a more truthful figure, we need to include the known costs that belong to getting and keeping the garment wearable.

Start with these.

Purchase price

Use the amount actually paid, after any discount, voucher or credit note. If you bought second-hand, use the price you paid, not an estimated original retail price. The old RRP is usually irrelevant to your own wardrobe maths.

Delivery, if it belongs to that item

If you paid postage for a single garment, include it. If you ordered several items together, split the delivery in a sensible way, or leave it out if you cannot allocate it fairly and it was minimal. The goal is not forensic accounting. It is a usable estimate based on real spending.

Alterations

Include alterations you knew were needed or actually paid for, such as trouser hemming, taking in a waist, replacing too-long straps, or moving a button. In the UK, this is often the difference between a garment we own and a garment we wear. If a second-hand wool coat cost little but needed relining or sleeve work, that belongs in the total.

Routine care

This is where it helps to be realistic. Routine care costs can include dry cleaning where the garment genuinely needs it, specialist detergent for wool or silk, and laundering costs if they are unusually high for that item. We do not need to assign a few pence of washing liquid to every cotton T-shirt. But if a suit, coat or delicate knit has regular care costs that are specific and known, include them.

Care labels matter here. Before assuming a garment is expensive to maintain, check what the label actually says and what the symbols mean. Some items marked with cautious care instructions can still be maintained carefully at home, while others really do require professional cleaning. If you need a refresher, our guide to reading washing symbols without ruining clothes is a useful place to start.

Known repairs

Include repairs you have already paid for, or repairs you know are immediately needed to make the garment usable. That could be resoling, replacing a zip, darning a hole, reattaching a lining, or fixing a fallen hem.

If you are deciding whether to repair or move something on, it helps to separate past spend from future spend. Past spend tells you what the garment has already cost you. A proposed repair is a fresh decision. We should not throw good money after bad purely because we have already spent money.

What not to include as though it were certain

Do not pad the total with guesses. If you think a coat might eventually need dry cleaning, but it has not yet, that is a forecast, not a known cost. If you might need to replace the heel tips on boots next year, note it separately if useful, but do not present it as money already spent.

That distinction matters because guessed costs can distort the result in either direction. We can make a garment look worse by loading it with hypothetical maintenance, or better by assuming a long life and low care needs without evidence.

A simple rule helps: use known costs in the main calculation, and keep forecasts in a separate column or note.

How to calculate it with a simple paper or spreadsheet table

You do not need an app, and you do not need an invented interactive tool. A notebook page or a basic spreadsheet is enough. The most useful format is one that separates forecast wears from logged wears, so we can compare what we expected with what actually happened.

Here is a reusable clothing cost per wear calculator format you can copy into paper, Notes, Excel, Google Sheets or any similar spreadsheet.

All the arithmetic above is hypothetical, but the method is the point.

Use these steps:

1. List one garment per row.
2. Enter the actual purchase price you paid.
3. Add any delivery cost that belongs to that item.
4. Add alterations you have paid for.
5. Add routine care costs that are specific and known.
6. Add repair costs already paid.
7. Total those figures.
8. Write a forecast wear number if you are considering a purchase or planning a season.
9. Keep a separate logged wear count once the garment is in use.
10. Divide total known cost by forecast wears for a provisional figure, then by logged wears for the real one.

If you are using a spreadsheet, that can be as simple as:

Total known cost = purchase + delivery + alterations + care + repairs

Forecast cost per wear = total known cost ÷ forecast wears

Actual cost per wear = total known cost ÷ logged wears

On paper, a tally mark system works well for logged wears. Keep the sheet in your wardrobe, in a drawer, or with your laundry basket if that is where you will actually see it.

Why logged wears beat good intentions

Forecasts are useful, but logged wears are where this becomes honest.

Most of us are much better at imagining a garment in our wardrobe than noticing how often we reach for it in real life. We picture outfits, occasions and future versions of ourselves. Then the neckline sits awkwardly, the fabric needs more fuss than we can be bothered with, or it never quite works with the shoes we actually wear.

Logging wears cuts through that.

A simple count over three to six months can tell us far more than memory does. It shows which items earn laundry priority because they are always in rotation, which ones sit untouched until we force ourselves to wear them, and which categories repeatedly disappoint us.

That is especially useful when forecast and reality diverge.

If forecast wears were high but logged wears stay low, ask why:

• Is the fit slightly off?
• Is the fabric itchy, clingy or too warm?
• Does it need a camisole, special bra or awkward shoes to work?
• Is the care too demanding?
• Did we buy for a version of our life we do not currently live?

The answer points to action. If the issue is fixable, alter or repair it. If it is not, stop waiting for the item to become itself and decide what to do next.

Logged wear data also helps us stop repeating the same purchase mistake. If three similar blouses all have high forecast use and low actual use, that tells us something about the category, not just the individual item. We may love the idea of them and dislike wearing them.

That is where a clothing cost per wear calculator earns its keep. Not because every item must hit some perfect low number, but because the comparison between forecast and logged use gives us evidence.

Use that evidence to decide whether to:

• keep and continue wearing
• repair because the item is clearly valuable in use
• alter because the barrier is specific and solvable
• resell or donate because it is not working for us
• stop buying that type of garment altogether

If you are on the fence about whether a repair is sensible, our guide on whether to mend it or move it on can help you think it through without guilt or sunk-cost logic.

How to use the number for better buying and better care

The best use of cost per wear is not as a scorecard. It is as feedback.

For second-hand shopping

Second-hand buying is a natural fit for this calculation because the purchase price often looks low while the true entry cost may include cleaning, mending or alterations.

A £14 blazer from a charity shop can still be excellent value, but if it needs £20 of tailoring before you will wear it, that should be part of the decision. Equally, a well-made second-hand coat that needs only a button and a brush may beat a cheaper new option very easily on real use.

When shopping second-hand, check:

• fibre content
• care label
• condition at stress points such as underarms, cuffs, hems and crotch seams
• missing buttons, broken zips and worn soles
• whether the fit issue is alterable or fundamental

Then estimate known immediate costs before buying. If the answer still looks sensible for how you dress, proceed. If it only works if everything goes perfectly, leave it.

For capsule planning

You do not need a rigid capsule to benefit from this. But if you are trying to build a smaller, harder-working wardrobe, logged wear counts show which colours, cuts and fabrics really anchor your week.

That can guide future buying much better than trend lists do.

If your most-worn items are washable dark knitwear, straight-leg trousers and weatherproof shoes, that is where replacement budget and care effort should go. If your least-worn items are pale dry-clean-only pieces that crease instantly, you have learned something useful about your real wardrobe, even if those items looked lovely on the hanger.

For care-label-led maintenance

Good care supports lower cost per wear, but only when it is proportionate. Not every garment needs pampering, and not every item is worth specialist treatment forever.

Use the care label as the starting point, then build habits that suit the fabric and your life. Wash less when less is enough. Air items between wears. Store knitwear folded rather than hanging if the shape is likely to stretch. Deal with small problems early.

For knitwear in particular, a little maintenance can make a well-used jumper look presentable for much longer. If pilling is putting you off wearing one of your better pieces, our guide to removing bobbles from jumpers without damaging the knit covers a careful approach.

One UK-specific note worth remembering is that care labels sold here generally follow familiar textile labelling conventions, but the exact legal framework is not identical to every EU rule in every detail after Brexit. For everyday wardrobe care, the practical point is the same. Read the symbols on the garment in front of you rather than assuming a generic rule.

For repair decisions

Cost per wear can make repair choices clearer.

If a pair of boots has already been worn heavily and a straightforward repair would return them to regular use, the next phase of wear may be very good value. If a dress has been worn twice in three years and needs expensive work before you even like it, repairing it may not make sense.

The key is to look forward as well as back. Past wear tells us whether the garment has been useful. Future likely wear tells us whether more spending is justified.

Without pretending every garment must last forever

Some clothes are workhorses. Some are occasional. Some wear out because they have done their job properly. A white T-shirt, running leggings, school uniform trousers or socks may never achieve a dramatic lifespan, and that is not automatically failure.

The goal is not to force every item into endless service. It is to buy with clearer expectations, care for things sensibly, repair where it makes sense, and notice when a category is not serving us.

If we keep the method simple, the number becomes genuinely helpful. Add up the known costs. Log the wears. Compare what we expected with what happened. Then use that information to build a wardrobe that works better, costs less to maintain, and asks less guesswork of us next time.
