The short version
- Typical range: £80 – £400 — see the full treadmill value guide
- What decides your price: condition, and how well you evidence it in photographs
- Cost to sell here: nothing, at any price
- Category: Sports & Outdoors
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.
- Run it at walking and running speed and listen for belt slip, motor whine or a grinding roller.
- Measure it assembled and folded, and weigh up honestly whether it fits through your doorway and down any stairs.
- Check the belt for wear down the centre and confirm the console, incline and safety key all work.
The photographs that sell a treadmill
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 treadmill assembled, side on, showing the whole deck
- The console lit and running, with the speed visible
- The belt surface close up, showing centre wear
- Folded, if it folds, with dimensions clear
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 It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover.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
Brand, model and whether it folds: “NordicTrack T7.5 Folding Treadmill, Working”. Folding is a major selling point and belongs in the title. Be upfront about which floor it is on — putting “ground floor, easy access” in a treadmill listing genuinely brings in buyers who would otherwise skip it.
Then state these in the description, because a buyer who has to ask is a buyer who might not bother:
- Brand, model, and maximum speed and incline
- Assembled and folded dimensions, plus approximate weight
- Which floor it is on and whether there are stairs
- Belt condition and whether the motor runs quietly under load
What buyers will actually ask
You will receive the same three messages about a treadmill. 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.
Give the weight and answer plainly. Most treadmills need two people and a van, and a buyer who arrives alone in a hatchback is a wasted afternoon for both of you.
Test it at running speed, not walking. Belt slip under load is the classic used-treadmill fault and it will be found immediately.
Measure it. If it does not fold and it will not fit, say so — the buyer may still want it but they need to plan.
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 treadmill 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 £240 sale — roughly the middle of the range for a treadmill — 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 | £240 |
| Poshmark | −£48 | £192 |
| eBay | −£33 | £207 |
| Mercari | −£24 | £216 |
| Etsy | −£16 | £224 |
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
Sharply seasonal. January is by far the strongest month, with a secondary lift in autumn. Selling one in June typically means accepting a much lower price or waiting.
Collection only, and access is the whole negotiation. State the floor, the stairs and whether you can help lift. Being honest about a first-floor treadmill loses you some enquiries and saves you many wasted appointments.
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 treadmill worth?
Typically £80 to £400 depending on brand, motor size and whether it folds. See the treadmill value guide for the range by condition.
Why are treadmills so hard to sell?
Almost always access rather than price. They are heavy, awkward and often upstairs. Listings that state the weight, the dimensions, the floor and whether the seller can help carry it sell far faster than those that do not.
When is the best time to sell a treadmill?
January, comfortably. New year demand is real and prices are noticeably higher than in summer, so holding one until January is usually worth doing.
