3 Direct costs for units sold

Enter cumulative costs for this sold group, once each. A blank is incomplete—not zero.

Actual fees

Total actual platform/payment fees for the sold units.

Actual postage

Postage actually paid for the sold units.

Other direct costs

Packaging, repair, or other direct costs for sold units.

Limits, allocation model & privacy

Money inputs are $0–$1,000,000 with up to two decimal places. Units bought are 1–1,000,000 whole units; units sold must be whole units from 0 through units bought. Blank required amounts are incomplete. Enter or explicitly confirm zero.

Each lot cost is allocated in whole cents: divide by units bought, then give one extra cent to the first remainder unit positions. An aggregate sold count represents the first sold positions. This is an equal-unit estimate, not a tax accounting method; it fits homogeneous units, not mixed lots with unequal item costs.

Receipts include item and shipping money before fees, excluding buyer tax and platform label pass-through. Actual fees, postage, and other direct costs are entered cumulatively for sold units and deducted once. Do not use an after-fee payout as receipts.

Illustrative estimate

Realized profit on sold units · before income tax

An initial before-tax estimate from the sold units. Calculate to see allocated sold cost, cash recovered, and the amount still tied up in the lot.

Equal allocation estimate, not a tax method. Divide acquisition cents by units bought: quotient cents per unit; assign one extra cent to unit positions 1 through the remainder. Aggregate sold units consume positions 1 through units sold. Current lot: $10.00 per unit, plus 1¢ for the first 0 unit positions. Sold cost $40.00 + remaining cost $60.00 = $100.00 exactly.

Sold acquisition cost is the allocated cost of units sold. Remaining inventory cost stays attached to unsold units; it is not expensed against partial sales.

Cash recovery and profit answer different questions. A lot can still have unrecovered purchase cash while its sold units already show a profit.

JavaScript is required to calculate or export. The visible $20 hypothetical example is static; controls remain disabled and entries are not submitted. The example shows $80 receipts less $20 direct costs and $40 allocated acquisition cost on four units sold: $20 realized profit, while $40 of the original $100 outlay remains unrecovered.

PROFIT, INVENTORY, CASH

A partial sale is not the whole lot.

Keep three numbers distinct: what sold units earned after their share of cost, what unsold stock still carries, and how much of the original outlay has come back in cash.

Give each unit its share

The all-in purchase is split across units in cents. Only the allocated acquisition cost of sold units is deducted from profit; the rest remains inventory cost.

Use receipts before fees

Count item and shipping receipts before fees, excluding buyer tax and platform label pass-through. Then subtract actual fees, postage, and other sold-unit costs once. Do not start with an after-fee payout.

Read cash recovery separately

Net cash is seller receipts less the direct selling costs entered. Compare that with the entire lot purchase: the shortfall is unrecovered outlay, while cash beyond the purchase is excess cash.

Keep the estimate in scope

Equal allocation is a practical estimate for homogeneous units, not a tax method or a valuation of what remains. Mixed-value goods need item-level costs to be understood accurately.

THE CENTS MATTER

One lot, several useful views.

Hypothetical 10-unit lot costing $100.00: 4 sold, receipts $80.00, fees $8.00, postage $12.00, other $0.00. Allocated sold cost $40.00; realized profit $20.00; 6 remaining with cost $60.00. Net cash recovered $60.00; unrecovered outlay $40.00; excess $0.00.

Hypothetical 3-unit lot costing $10.00: 1 sold, receipts $5.00, fees $0.00, postage $0.00, other $0.00. Allocated sold cost $3.34; realized profit $1.66; 2 remaining with cost $6.66. Net cash recovered $5.00; unrecovered outlay $5.00; excess $0.00. The first unit gets $3.34; positions 2 and 3 get $3.33 each. Cumulative sold costs are $0.00, $3.34, $6.67 and $10.00.

Hypothetical 3-unit lot costing $10.00: 1 sold, receipts $2.00, fees $3.00, postage $2.00, other $1.00. Allocated sold cost $3.34; realized profit -$7.34; 2 remaining with cost $6.66. Net cash recovered -$4.00; unrecovered outlay $14.00; excess $0.00.

MODEL & LIMITS

Clear numbers, bounded assumptions.

Allocation in cents: For lot acquisition total cents T and bought quantity B, compute q = floor(T / B) and r = T mod B. The first r unit positions receive q + 1 cents; all later positions receive q. An aggregate sold quantity uses the first sold positions. For example, $10.00 across 3 units allocates $3.34, $3.33, and $3.33. This deterministic remainder rule makes allocated cost add back to the original lot cost.

Profit and cash: Net cash = receipts − fees − postage − other. It can be negative. Realized profit = net cash − sold acquisition cost. Unrecovered initial outlay = max(0, total lot cost − net cash); excess cash = max(0, net cash − total lot cost). Negative net cash can make unrecovered outlay exceed the purchase cost. Remaining inventory cost is the cost allocated to units not yet sold, not a positive “profit slice.”

Profit margin is realized profit divided by receipts and is unavailable when receipts are zero. Sold-cost ROI is realized profit divided by sold acquisition cost and is unavailable when sold acquisition cost is zero. Recovery percentage is unavailable when lot cost is zero. Ratios are signed, so losses remain negative rather than being hidden.

The estimate assumes homogeneous units and equal unit allocation. Unequal-value mixed goods, market forecasts, returns, income tax, time, and unentered costs are outside the model. All-in purchase cost includes purchase tax and acquisition transport. Seller receipts include item and shipping money before fees, excluding buyer tax and platform label pass-through; actual fees, postage, and other costs are cumulative for sold units, counted once.

Lot profit calculator FAQs

How can a lot be profitable before I have recovered its cost?

Profit is measured on sold units: net cash from those sales less their allocated share of acquisition. Cash recovery compares all net cash so far with the entire lot purchase. Sold units can be profitable while some of the original purchase is still unrecovered because other units remain unsold.

Why is the unsold inventory cost not subtracted from profit?

Those units have not been sold. Their allocated acquisition cost remains attached to remaining inventory instead of being expensed against the partial sales. This estimate does not predict their future selling price or profit.

How are pennies allocated across the lot?

The cost is divided into whole cents. Each unit gets the floor-cent share, and the first remainder unit positions receive one extra cent. For $10.00 over 3 units, the shares are $3.34, $3.33, and $3.33. Aggregate sold quantity represents the first sold positions.

What does seller receipts include?

Enter item and shipping receipts for sold units before fees, excluding buyer tax and platform label pass-through. Then enter actual fees, postage, and other direct costs separately. Do not use an after-fee payout as receipts: it would hide those fees and change the margin denominator.

Can net cash or unrecovered outlay be negative?

Net cash may be negative when entered costs exceed receipts. Unrecovered outlay is never below zero; if net cash is negative, the unrecovered amount can be larger than the original lot purchase. Excess cash is shown separately when net cash exceeds total lot cost.

What if no units have sold?

Zero sold is valid when seller receipts, fees, postage, and other costs are each explicitly zero. If any of those amounts is nonzero, the inputs describe an inconsistent sold group and should be corrected. Acquisition cost and remaining inventory cost remain distinct from profit.

Does equal allocation work for a mixed lot?

It is only a useful estimate when units are reasonably homogeneous. A lot of items with very different purchase values needs item-level acquisition costs; an equal split can distort the profit on any specific item. This is not a tax accounting method.
