Know what you'll actually keep before you list it.

Flip Side is a profit calculator built for resellers. Research any item and test prices and Flip Side shows the money you really keep after eBay's fees, shipping costs, and the taxes on your side-hustle income. Your profit is right at the top, updated as you type.

RESEARCH, SIDE BY SIDE WITH YOUR PROFIT
- Search eBay sold listings, Mercari, Poshmark, Whatnot, and Facebook Marketplace to see what an item actually sells for
- Compare new prices at Amazon, Walmart, Target, Best Buy, and Google Shopping
- Scan a barcode with your webcam (or a USB scanner) to find the item by name
- No barcode? Take a photo and look it up with Google Lens
- Highlight a price on any page and it becomes your sale price instantly; highlight an item's name and it becomes your search
- Your favorite search site is remembered as your default

PROFIT CALCULATOR
- eBay final value fee and per-order fee, figured on the sale price, shipping, and sales tax the way eBay charges them
- Shipping the buyer pays and the label you pay for, including listings where you pay the shipping
- Estimated self-employment tax, federal income tax, and state income tax
- Pick your state from all 50 states plus DC, and set your own federal and state rates
- A clear breakdown from sale price down to net profit, with your margin
- Your tax settings are remembered between sessions

PRIVATE BY DESIGN
- No account needed
- Your numbers and settings stay on your PC
- Search pages are shown as the sites themselves display them; Flip Side only uses text you highlight
- Photos stay on your PC unless you choose to search with them in Google Lens
