What does this flip actually leave?

Build a forward estimate from the money credited to you, fees you expect, and the costs you already know. Keep the estimate separate from what a completed sale eventually records.

A FORWARD ESTIMATE

Set up the flip.

Illustrative example loaded: $65 sale, $22 all-in acquisition, $8 actual postage, and $9.60 actual fees. Change an amount, then calculate.

1 Seller receipts

Item sale price

The item amount credited to you, before buyer tax and shipping.

Shipping received by you

Only shipping credited to the seller. Do not enter a platform label pass-through.

Keep shipping distinct: seller-credited shipping can add to revenue. A platform label pass-through is not seller revenue. Subtract the actual postage you paid once below.

2 · Choose how to enter fees

Use an actual total from an order, or model an unverified percentage and fixed fee. They never stack.

Fee entry mode Actual total fees replace the manual percentage and fixed fee.

Enter actual total fees

One total fee amount, deducted once. No manual fee is added on top.

Actual total fees

Enter the total fees for this estimate, or explicitly confirm $0.

3 · Count the direct costs

Use all-in acquisition for what it took to source the item. A blank cost is incomplete, not zero.

All-in acquisition cost

Include purchase tax and acquisition transport here; do not count them again.

Actual postage paid

Your actual postage expense, subtracted once from profit.

Other direct costs

Packaging, repair, or another direct item cost not counted above.

Limits, assumptions & privacy

USD money inputs are limited to $0–$1,000,000 with up to two decimal places; the manual rate is 0–100% with up to two decimals. Blank required amounts are incomplete. Enter or explicitly confirm zero where no amount applies.

For manual fees, percentage is rounded half-up once to cents, then fixed cents are added. Shipping received and entered buyer tax may be included in that unverified percentage base by choice. Buyer tax never enters revenue. Actual total fees replace, rather than combine with, both manual fee assumptions.

This general forward estimate does not automatically model income tax, returns, time, overhead, unentered costs, or tiered, capped, minimum, or promotional fee rules. It does not verify a marketplace fee or produce a payout. Margin is unavailable when seller revenue is zero; acquisition ROI is unavailable when acquisition is zero.

Numbers are used in this page only: there is no account transfer, save, or sync. Page views are consent-aware; calculator inputs and actions are not tracked.

An illustrative estimate stays here. It is not a recorded sale or a bank payout, and it is never transferred to your Upcyclist account.

Enter the costs you know. This estimate cannot verify fee terms, returns, or other order adjustments.

FROM RECEIPTS TO PROFIT

A sale amount is not the amount you keep.

Start with what is credited to the seller. Deduct one fee total and each direct cost once. The remainder is a focused estimate, with the assumptions visible.

Count seller revenue only

Item price and shipping actually credited to you make up seller revenue. Buyer tax and platform label pass-through do not. Deduct the actual postage you paid once as a cost.

Choose one fee method

Enter a single actual fee total, or use a manual percentage plus fixed fee. The actual amount replaces the assumptions; it never gets added to them.

Bring the whole acquisition cost

Purchase tax and transport to acquire the item belong in all-in acquisition. Keep them there instead of repeating them in other costs.

Read estimate and outcome separately

This tool looks forward from assumptions. A recorded outcome belongs to a completed sale and may differ because of actual fees, adjustments, returns, or costs not entered.

THREE POSSIBLE OUTCOMES

Actual fees, manual fees, and a loss.

Item price $65.00 + shipping received $0.00 = seller revenue $65.00. Subtract acquisition $22.00, postage $8.00, fees $9.60 and other costs $0.00 once: profit $25.40, margin 39.08%, acquisition ROI 115.45%. Actual total fees $9.60 replace all manual fee assumptions. No extra percentage or fixed charge is added.

Item price $55.00 + shipping received $10.00 = seller revenue $65.00. Subtract acquisition $22.00, postage $8.00, fees $9.60 and other costs $0.00 once: profit $25.40, margin 39.08%, acquisition ROI 115.45%. Unverified manual fees: 14.00% × $65.00 + $0.50. Fee base includes item price; shipping included; buyer tax excluded. Buyer tax is never seller revenue.

Item price $30.00 + shipping received $0.00 = seller revenue $30.00. Subtract acquisition $22.00, postage $8.00, fees $4.50 and other costs $1.00 once: profit -$5.50, margin -18.33%, acquisition ROI -25.00%. Actual total fees $4.50 replace all manual fee assumptions. No extra percentage or fixed charge is added.

SCOPE & LIMITS

Useful precision, without pretending to know more.

This is a general, forward-looking reseller estimate in USD—not a marketplace preset, reverse calculator, live fee lookup, settlement statement, or recorded outcome. Actual total fees replace the optional manual percentage and fixed fee.

Seller revenue is the item amount plus shipping credited to the seller. A platform label pass-through is excluded; actual postage paid is a separate cost deducted once. Buyer tax never counts as revenue. It may be entered in the fee base only when the manual buyer-tax option is selected.

All-in acquisition includes purchase tax and transport to source; do not double count those in other costs. Estimate excludes income tax, returns, time, overhead, unentered expenses, and automatic tiered, capped, minimum, or promotional fee rules. Actual orders can also include adjustments outside the model.

Amounts are accepted from $0 to $1,000,000 with at most two decimal places. Manual rates are 0–100% with at most two decimals; the percentage fee is rounded half-up once to cents, then fixed cents are added. These are calculation assumptions and input limits, not marketplace terms.

Inputs and exports stay in this page; there is no account transfer. Page views are consent-aware, and calculator input or action tracking is not used.

Reseller profit calculator FAQs

What is profit margin, and how is it different from ROI?

Profit margin is estimated profit divided by seller revenue (item price plus shipping credited to you). Acquisition ROI is estimated profit divided by all-in acquisition cost. Either ratio is unavailable when its denominator is zero.

Why can’t I add actual fees to the manual percentage?

The modes are intentionally exclusive. Actual total fees are the fee deduction by themselves. Manual mode estimates percentage on its selected base, rounds that percentage half-up once to cents, then adds the fixed fee. Combining the two would count fees twice.

How do shipping and buyer tax affect the estimate?

Only seller-credited shipping is added to revenue. A platform label pass-through is not revenue, and actual postage you paid is deducted once. Buyer tax is never revenue; when manual mode is active, you can optionally enter it for the assumed percentage fee base only.

Does a blank amount mean zero?

No. Every active amount is required, and a blank or malformed value is incomplete—not silently treated as zero. Enter an explicit 0 or use its Confirm $0 control where available. Inactive fee-mode inputs are not included.

Are my inputs saved or sent to my account?

No. Calculation, copy, and download use the page; nothing is saved, synced, or transferred to your Upcyclist account. Page views are consent-aware, and calculator inputs and actions are not tracked.

What do copy and download include?

They provide a text summary of the active fee assumptions, entered amounts, estimate breakdown, ratios, rounding, and important limits. They do not transfer the estimate into an account or establish a recorded outcome.

Is this a reverse calculator?

No. Enter a sale price and costs to estimate forward profit. It does not calculate a target sale price from a desired profit or acquisition budget.

What costs and fee rules are not modeled automatically?

Income tax, returns, time, overhead, unentered costs, and tiered, capped, minimum, or promotional fee rules are not automatic. Use a known actual total when available; manual percentage and fixed-fee inputs remain unverified assumptions.
