Sell Your Used Kettlebell — 0% Fees

A used kettlebell typically sells for £12 to £70, and on WishThrift it costs you nothing to list — no fee, no commission, so you keep the whole amount you agree. Kettlebells are priced by the kilogram, so lead with the weight and whether it is cast iron or vinyl coated — those two facts are the entire listing.

The short version

Typical range: £12 – £70 — see the full kettlebell value guide
What decides your price: condition, and how well you evidence it in photographs
Cost to sell here: nothing, at any price

Before you photograph it

Ten minutes here is worth more than anything else you will do. Buyers are deciding between your listing and someone else’s, and preparation is what visibly separates the two.

Confirm the weight in kilograms, usually cast into the bell or printed on the base.
Check the handle for rust, chips or rough casting seams, which matter because hands go there.
Clean off surface rust with a wire brush and note whether it is competition-spec or standard.

The photographs that sell a kettlebell

Four photographs do almost all the work. Shoot in daylight, near a window, with the item against something plain — and do not use the flash, which flattens texture and hides exactly what buyers are trying to see.

The handle close up, showing the finish
The base, showing whether it sits flat
Any rust, chip or coating damage

Photograph the flaws too. It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover. Buyers who can see the damage stop imagining something worse.

Writing the title and description

Weight and type: “24kg Cast Iron Kettlebell, Powder Coated”. Weight in kilograms is the search. Say cast iron, vinyl coated or competition spec, since the handle and balance differ and lifters care.

Then state these in the description, because a buyer who has to ask is a buyer who might not bother:

Weight in kilograms
Cast iron, vinyl coated, or competition spec
Handle diameter and finish, and whether it is smooth
Any rust, chips or casting flaws

What buyers will actually ask

You will receive the same three messages about a kettlebell. Answering them in the listing itself removes the back-and-forth, and answering them well when they do arrive is what turns an enquiry into a sale.

“What weight is it exactly?”

Read the casting and give kilograms. Buyers are filling a gap in a set and need the precise number.

“Is the handle smooth?”

Run your hand around it and check for casting seams. A rough handle tears skin and is the main complaint about cheap bells.

“Is there rust?”

Brush it and photograph honestly. Surface rust on cast iron is normal and cleans off; buyers accept it when shown.

Pricing it so it actually sells

Start from the honest condition grade rather than the price you hope for. WishThrift listings use five grades — New with Tags, Like New, Good, Fair and For Parts — and what each grade means is worth reading before you choose, because grading up is the most expensive mistake sellers make. It does not raise the price; it produces a buyer who arrives expecting something else.

The kettlebell value guide prices all five grades for this item. Pick your grade, take the figure, and if you sit between two grades price toward the lower one. Items priced honestly sell faster than items priced hopefully, and on a free platform there is no fee eating the difference anyway.

What you keep, compared

On a £41 sale — roughly the middle of the range for a kettlebell — here is what the commission-charging platforms would take, and what you would keep on each:

Where you sell it	Fee	You keep
WishThrift	£0	£41
Poshmark	−£8	£33
eBay	−£6	£35
Mercari	−£4	£37
Etsy	−£3	£38

Seller-side rates verified 26 Jul 2026 — Poshmark: 20% commission on sales of $15 and above; eBay: 13.6% final value fee, plus a per-order fee; Mercari: flat 10% selling fee; Etsy: 6.5% transaction fee, plus a listing fee and payment processing. Percentages are applied to the sterling figure above; the fixed per-order and processing charges those platforms add are quoted in their own currency and are not included here, so the real deductions are slightly larger.

Timing and getting it to the buyer

January is the peak by a wide margin, with an autumn lift. Free weights hold value well because they never wear out.

Extremely dense, so postage is often uneconomic — always weigh and quote before agreeing. Collection is normal and buyers expect it.

WishThrift does not process payments or arrange delivery — you and the buyer agree both directly — so confirm payment has cleared before the item leaves your hands, and keep the conversation on the site so there is a record of what was agreed.

Frequently asked questions

What is a used kettlebell worth?

Typically £12 to £70 depending on weight, and buyers compare on price per kilogram. See the kettlebell value guide.

Does rust matter on a kettlebell?

Surface rust cleans off with a wire brush and barely affects the price when disclosed. Deep pitting on the handle matters more, because that is what your hands grip.

Can I post a kettlebell?

Rarely economically. They are extremely dense and courier weight surcharges frequently exceed the value of the bell. Collection is the practical option.
