Net ROI, hourly return, cash velocity, and target buy price
A reseller ROI decision needs more than buy price and sale price. This calculator models gross revenue, platform fees, buyer-paid shipping, seller-paid shipping, packing supplies, return or discount reserve, labor time, a target hourly rate, expected days to sell, and a target ROI ceiling for max buy price.
The platform preset uses the shared marketplace-fee model in this repo, so buyer shipping and estimated buyer tax can be included when the public fee rule uses an order-total basis. The result shows profit, ROI, margin, hourly rate, monthly profit velocity, and the maximum buy price for your target ROI.
Use the decision panel before buying. Low ROI, low hourly return against your own threshold, slow cash velocity, or negative profit should change the sourcing action even when the gross sale price looks attractive.
- Inputs: buy price, expected sale price, buyer shipping, buyer tax, platform fees, seller label, packing, reserve, labor, hourly target, days to sell, and target ROI.
- Output decision: works on paper, low ROI, low hourly return, slow cash velocity, or skip/counter.
- Risk prevented: tying up cash in slow inventory because the percentage ROI looked good without time and reserve costs.

Frequently Asked Questions
How do you calculate ROI for a resale flip?
Subtract platform fees, seller-paid shipping, packing costs, reserve, and buy cost from gross revenue, then divide profit by total cost. This calculator also shows margin, hourly return, and cash velocity.
Why include buyer-paid shipping and buyer tax?
Some marketplace fee models use an order-total basis. When a platform preset depends on buyer shipping or tax, entering those fields gives a better fee estimate than a simple percentage of item price.
What is max buy price?
Max buy price is the highest amount you can pay for the item while still reaching your selected ROI target after modeled fees, shipping, packing, and reserve.
Should I source an item with low ROI but fast sell-through?
Possibly, but only if the dollar profit and hourly return are worth the work for your target. The velocity metric helps compare a fast lower-margin item against a slow higher-margin item.
