Will the parts earn a profit on that unit?
List the parts you'd pull. Fees, shipping, and what you'd pay come off. What's left is yours, before your own time.
Built by Ordovee, out of 15 years of real shop work in our own parts operation.
Every box is empty and ready to type in. The grey text is only an example of what goes where — not market data, and nothing to delete first.
The parts you'd pull
What a buyer pays you for each part, and what it costs you to ship it.
Fees, and what you'd pay
The fee comes off the parts total. Use whatever your marketplace actually charges you — it's on your last payout statement.

Who built this
We run Part Haven, a parts recovery business — machines coming in, parts coming off, shelves filling up, listings going live. Ordovee is the system we built to keep that work moving. It started in FileMaker more than 15 years ago, inside the same operation, and Part Haven runs on ODV today. More about the shop.
How do you work out what a unit is worth parting out?
Four numbers.
- Parts total — what every part you'd pull should bring, added up.
- Marketplace fees — your percentage, off that total.
- Shipping — what each part costs you to get to its buyer, added up.
- What you'd pay for the whole unit.
What's left is your potential profit on the buy, before your own time — and you already know what your time is worth.
The list is where your judgment goes. Put down the parts you're confident have a buyer within reach, at a price you've actually seen one sell for. An honest list is usually shorter than the one in your head, and the total it produces is one you can act on. The math is the same whether the unit is a laptop, a washer, a motorcycle, or a combine — only the numbers change. (Parting out, expected value.)
Why shipping goes in on every part
A RAM module and a laptop screen do not ship anything alike, and neither do a control board and a tractor hood. One lump shipping figure hides the parts that quietly eat their own margin — the heavy ones, the awkward ones, the ones that end up local-pickup-only. A line per part keeps that visible while you're still deciding whether to buy. Run the car starting point and watch what shipping does to the bottom line; that one is honest on purpose.
Does the part fit anything else?
Typing out the parts you'd pull is also the moment you decide which ones have buyers, and that turns on what else each part fits. A control board that spans six part numbers, a pump used across a whole product line, a wheel that bolts to four machines — those are the parts that carry a list. That answer lives in whatever you wrote down the last time you took one of these apart: a parts compatibility cross-reference built part by part, in a catalog you build instead of one you license. (Fitment.)
When the prices come from your own sold orders
On this page, every price is one you typed.
Inside Ordovee the same four terms run against your own records. Pick a part and ODV fills in what your own sold orders brought for it over the last 365 days — how many sold, and the average your buyers actually paid. Those are your sales, read back to you. ODV does not price parts.
The run starts from a source assembly already in your catalog, so the parts list opens as the parts that assembly is already linked to instead of a blank page. Shipping still goes in per part. The fee percentage is still yours.
And the number stops evaporating. Name it, save it, edit it later, duplicate it for the next unit like it, and write down the things you'd otherwise lose by Thursday — why you walked, what the seller claimed, what looked wrong about the left side. Every one lands in a library you can search, sort, filter, and page through.
Open a source assembly and you see its history: every estimate you've run against one, every one you've bought, and a strip reading what you've averaged per unit, what you've spent in total, what you paid last time, and what this buy nets. Purchases are never overwritten — you archive and re-enter — so the record stays a record. The arithmetic is identical. What changes is where the prices come from, and whether the number is still there tomorrow.
Frequently asked questions
Is the part-out calculator free?
Yes — no account, no email, and nothing is uploaded to a server. The math runs in your browser and your numbers never leave it. It is built by Ordovee, and the product links on this page are the only trade for keeping it free.
What price should I enter for each part?
The gross price a buyer pays you for that part — what shows on the listing, before marketplace fees come out. Do not discount it for fees, condition, or how likely it is to sell. The calculator takes fees off the parts total and shipping off per part, so entering an already-adjusted number subtracts the same cost twice.
Why is shipping entered on every part instead of once?
Because a RAM module and a laptop screen do not ship anything alike, and neither do a control board and a tractor hood. A single lump figure hides the parts that quietly eat their own margin — the heavy ones, the awkward ones, the ones that end up local-pickup-only. A line per part keeps that visible while you are still deciding whether to buy.
What percentage do marketplaces take when you sell parts?
Around 13% is a common working number for a parts listing, which is why the calculator starts there — but use what your marketplace actually charges you. It is on your last payout statement. The fee applies to the parts total, not to the shipping you pay.
Does it work for appliances, laptops, and equipment, or only cars?
All of them. The arithmetic does not change with the machine: parts total, fees off, shipping off, what you paid off. There are five starting points — laptop, appliance, powersports, tractor or equipment, and car or truck — and every row is editable, so a washer, a sled, a combine, and a pallet of laptops all run the same way.
What are the grey numbers in the boxes?
Examples, not values. Every box starts empty so there is nothing to delete before you type — the grey text just shows the shape of a plausible answer for that kind of unit. They are not live market data and not a pricing feed, and nothing is counted until you type a number in. The total is only as good as what you put in it.
If the unit is worth the bench time, the next question is keeping track of what comes off it — from whole unit to sold part on one system. Parting out more than a couple of units a month? See the product overview, or tell us what you're buying and we'll tell you straight whether ODV fits. The calculator stays free either way.
