Flip profit formula with target sale price
Use this calculator before buying or accepting an offer. Enter expected sale price, buy cost, platform, buyer-paid shipping, buyer tax if it is part of the fee basis, seller shipping, supplies, reserve, labor, and target profit.
The output separates net profit, ROI, margin, hourly return, break-even sale price, and the sale price needed to hit your target. A flip can look profitable before fees but fail once shipping, markdown reserve, and labor are included.
Platform presets use the shared Underpriced US marketplace fee policy reviewed on August 6, 2026. Account-specific seller discounts, promoted listings, international fees, refunds, and tax treatment still need receipt-level verification.
- Primary decision: buy, renegotiate, list higher, or skip.
- Inputs match the sourcing moment: buy price, expected comp, platform, shipping, fees, reserve, labor, and target profit.
- Best next action: use break-even and target sale price before buying or accepting an offer.

Frequently Asked Questions
What costs should a reseller include in flip profit?
Include buy price, platform fees, seller shipping, supplies, repair or prep costs, return or markdown reserve, and labor time. Buyer-paid shipping should be entered separately from seller shipping because it can be revenue and also part of the fee basis.
How is ROI calculated on a flip?
ROI is net profit divided by cash invested. In this tool, cash invested includes buy cost, seller shipping, other costs, and reserve. The result is a planning estimate, not a replacement for final marketplace receipts.
Why does the calculator show a target sale price?
Break-even only tells you the minimum price to avoid losing money. Target sale price shows what you need to charge to hit your chosen net profit after the selected fee basis, shipping, costs, and reserve.
Can this replace exact marketplace fee reports?
No. The presets are reviewed US planning models. Store discounts, promoted listings, international fees, tax on fees, refunds, and account-specific programs should be checked against the final transaction record.
