Sell Your Used Keyboard Piano — 0% Fees

A used keyboard piano typically sells for £50 to £300, and on WishThrift it costs you nothing to list — no fee, no commission, so you keep the whole amount you agree. Keyboards sell on key count and whether the keys are weighted, and those two facts decide whether the buyer is a beginner, a student or a gigging player.

The short version

Typical range: £50 – £300 — see the full keyboard piano 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.

Count the keys and establish whether the action is weighted, semi-weighted or unweighted synth action.
Test every key and every control for dead notes, sticking keys and crackling sliders.
Locate the power supply, which is very often proprietary, and the sustain pedal and stand if you have them.

The photographs that sell a keyboard piano

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.

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 It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover.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

Key count and action: “Yamaha P-45 88 Key Weighted Digital Piano”. Those are the two filters buyers apply first. Say whether the power supply is included, because proprietary adapters are expensive and their absence is a real deduction.

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

Number of keys and the action type: weighted, semi-weighted or synth
Brand, model, and whether it has built-in speakers
Whether the power supply, sustain pedal and stand are included
Any dead or sticking keys, and the condition of the controls

What buyers will actually ask

You will receive the same three messages about a keyboard piano. 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.

“Are the keys weighted?”

Press one and feel for resistance, or check the specification. Weighted actions suit piano students and unweighted ones suit synth players — entirely different buyers.

“Are there any dead keys?”

Play every single one. A dead note is the most common fault and the easiest to check, so buyers assume you have.

“Is the power supply included?”

Confirm it and note the voltage. Proprietary adapters can cost a significant fraction of a budget keyboard’s value.

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 keyboard piano 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 £175 sale — roughly the middle of the range for a keyboard piano — 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	£175
Poshmark	−£35	£140
eBay	−£24	£151
Mercari	−£18	£157
Etsy	−£11	£164

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. Full breakdown: marketplace selling fees compared.

Timing and getting it to the buyer

Steady with a strong Christmas lift and a September bump as lessons start. Weighted 88 key instruments sell fastest.

Long and awkward rather than heavy. Postage needs a long box and is expensive; collection is usual and lets the buyer play every key, which is exactly what they want to do.

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 keyboard piano worth?

Typically £50 to £300 depending on key count, action and brand. Weighted 88 key models sit at the top. See the keyboard piano value guide.

What is the difference between weighted and unweighted keys?

Weighted keys resist your finger like an acoustic piano and suit anyone learning properly; unweighted synth action is lighter and faster and suits synth and organ playing. Buyers care a great deal which one they are getting.

Does a missing power supply matter?

Yes, more than people expect. Many keyboards use proprietary adapters with unusual voltages, and sourcing one can cost a meaningful share of the instrument’s value. Say clearly whether yours is included.
