Flipping items for profit looks straightforward on the surface: buy low, sell high. But the real picture is more complex. Platform fees alone can eat 5–20% of your revenue. Shipping costs reduce margins on low-priced items. And the time you spend sourcing, listing, photographing, packing, and shipping directly affects your real hourly rate. This calculator analyzes every item in your flipping operation and reveals the metrics that actually matter: profit per item, margin percentage, return on investment, and your effective hourly rate. That last number — what you're actually earning per hour — is what determines whether your side hustle is worth your time or whether you're better off doing something else. Platform choice has a massive impact. eBay charges 13.25%, Poshmark takes a flat 20%, StockX around 9%. Switching from Poshmark to a lower-fee platform for the right items can increase your take-home by 25% or more on the same sales. Enter your items, selling prices, platforms, and time spent to get a complete picture of your flipping income — and projections for what you could earn at different monthly volumes.

Alex buys vintage cameras at thrift stores for $20–$40 and resells on eBay for $80–$120. After eBay's 13.25% fee and $12 shipping, a camera bought at $25 and sold for $95 nets $64.43 — a 68% margin and 157% ROI. At 1.5 hours per flip, that's $42.95/hour. By comparison, Alex also flips designer jeans bought at $15 and sold for $45 on Poshmark — but after Poshmark's 20% cut, profit is only $21. At 45 minutes per transaction that's $28/hour — still good, but Alex should focus on cameras for maximum hourly return.
- ✕Ignoring platform fees when pricing — always work backwards from sell price minus fees
- ✕Not tracking your time — a small profit that takes hours is not worth it
- ✕Forgetting shipping costs — especially on heavy or oversized items
- ✕Not researching sold prices on eBay before buying — check actual sale prices, not listed prices
- ✕Underpricing items to move them faster — patience often doubles your margin
What items are most profitable to flip?
Electronics, vintage cameras, tools, sneakers, luxury handbags, and vintage clothing typically offer the best ROI. Focus on categories where you have sourcing knowledge and where market prices are stable and researched.
Which platform has the lowest selling fees?
Facebook Marketplace charges 5% for shipped items and nothing for local pickup. Craigslist is free for local sales. eBay (13.25%), Poshmark (20%), and Mercari (10%) charge more but provide larger audiences.
Do I have to pay taxes on flipping income?
Yes. Reselling income is self-employment income. The IRS requires reporting and you'll owe self-employment taxes (~15.3%) plus income tax on net profit. Keep detailed records of all purchase costs (cost of goods sold) since these reduce your taxable income. Platforms like eBay and Poshmark send 1099-K forms when you exceed $600/year in sales.
What's a good profit margin for flipping items?
Margins above 30% are solid; above 50% is excellent. More important is your effective hourly rate — a 70% margin on a $10 item that takes 2 hours earns you $3.50/hour, which is not worth your time.
How do I find items to flip profitably?
Check eBay 'sold listings' before buying anything to see actual market prices. Source from thrift stores, estate sales, Facebook Marketplace, garage sales, and clearance sections. The best flippers develop specific category expertise.
