Where does the gain or loss go?

Usually "other income/expense" below operating income — it's not part of normal sales. Some businesses that routinely sell equipment show it in operations.

Is the book gain the same as the taxable gain?

Rarely. Tax depreciation (MACRS, bonus, §179) is usually faster than book, so the tax basis is lower and the taxable gain is bigger — and much of it is recaptured as ordinary income.

What if I traded it in?

A trade-in is an exchange, not a cash sale. The trade-in allowance works like proceeds for the gain or loss, but the new asset's cost gets involved — worth a look with your accountant.

Does the spreadsheet recalculate?

Yes. Book value, gain or loss, and every line of the journal entries are formulas off the Inputs sheet.

Heads up

For taxes, a gain on depreciated equipment is usually ordinary income up to the tax depreciation taken (recapture) — see the Depreciation Recapture calculator.

Gain or loss: $750.00; Gain on disposal
Book value at disposal: $5,750.00; 11.50% of the original cost
Net proceeds: $6,500.00; Sale price − selling costs
Accumulated depreciation at disposal: $44,250.00

Journal entries

Book the catch-up depreciation (if any) first, then the disposal.

Journal entries
Account	Debit	Credit
06/30/2030 — Bring depreciation up to the disposal date first
Depreciation expense	$1,500.00
Accumulated depreciation		$1,500.00
Totals	$1,500.00	$1,500.00
06/30/2030 — Record the sale (gain)
Cash — sale proceeds	$7,000.00
Accumulated depreciation	$44,250.00
Equipment (at original cost)		$50,000.00
Cash — selling costs paid		$500.00
Gain on disposal of assets		$750.00
Totals	$51,250.00	$51,250.00

What this does

When an asset leaves the business — sold, scrapped, stolen, whatever — it has to come off the books. This figures what it was still worth on the books (cost minus accumulated depreciation), compares that to what you got for it, and writes the entry.

It also reminds you to catch up the depreciation to the disposal date first, which is the step everybody forgets.

How the math works

book value = original cost − accumulated depreciation
net proceeds = sale price − selling costs
gain (or loss) = net proceeds − book value

The entry wipes out both sides of the asset: credit the asset at its original cost, debit the accumulated depreciation, record the cash, and the plug is the gain or loss.

A gain here doesn't mean you made money on the asset. It usually means you depreciated it faster than it actually lost value.

Check my math: a worked example

Equipment that cost $50,000 with $42,750 of depreciation booked (plus $1,500 still to record for this year) sells for $7,000, with $500 of selling costs.

Accumulated depreciation at the sale: $44,250.00.
Book value: $50,000.00 − $44,250.00 = $5,750.00.
Net proceeds: $7,000.00 − $500.00 = $6,500.00.
Gain: $6,500.00 − $5,750.00 = $750.00.

The entry below takes the asset and its accumulated depreciation off the books and records the cash and the gain or loss.

These numbers come straight from the calculator using its example inputs — if the math ever changes, this example changes with it.

Mistakes I see a lot

Skipping the depreciation for the months before the sale. Book it first, or the gain is overstated.
Crediting the asset for its book value instead of its original cost. Cost and accumulated depreciation both come off.
Netting selling costs in your head and forgetting them in the entry.
Leaving fully depreciated assets on the books after they're gone. Scrapped assets need an entry too (with no proceeds).

Assumptions and limits

Book value = original cost − accumulated depreciation at the disposal date (including any depreciation you still need to record up to that date).
Gain or loss = net proceeds (sale price − selling costs) − book value.
The entry removes the asset at its original cost and its accumulated depreciation, records the cash in and out, and books the difference as a gain or loss.
Book (GAAP) treatment. Taxes are separate — gains on depreciated property usually involve depreciation recapture.
Cash sales and abandonments only; trade-ins and like-kind exchanges follow different rules.
