Frequently Asked Questions

What ROI percentage is considered good for thrift flipping?

Most experienced resellers target an ROI of at least 100% (doubling their money) on clothing and 50–80% on furniture or larger items. Below 30% ROI, the time spent listing, packing, and shipping often makes the flip not worth it unless you're moving volume quickly. A 150–300% ROI is achievable on vintage brand-name clothing and is what top Poshmark and eBay sellers aim for.

How do I account for items that don't sell?

Unsold inventory is a real cost of the resale business. A common approach is to set aside 10–15% of your gross sales as a "dead stock" buffer. If you bought 10 items at $10 each and 2 never sell, your effective sourcing cost on the 8 that did sell is higher than $10 each. The more selective you are at the thrift store, the lower your dead stock rate — experienced sellers pass on anything they aren't confident will sell within 30–60 days.

Should I include my time in the ROI calculation?

Tracking time is optional for ROI but essential if you want to know your effective hourly rate. Use the time field in this calculator to see how much you earned per hour on a flip. Many resellers discover their hourly rate is lower than they thought once sourcing, cleaning, photographing, listing, and packing time is included. High-value, fast-selling items beat low-value, time-intensive ones every time.

What's the difference between ROI and profit margin?

ROI is calculated against your cost — a $30 profit on a $10 investment is 300% ROI. Profit margin is calculated against your revenue — that same $30 profit on a $40 sale is a 75% margin. Both are useful: ROI tells you how efficiently your sourcing dollars are working; margin tells you how much of each sale you actually keep. For thrift flipping, most sellers find ROI more intuitive when evaluating whether an item is worth picking up at the thrift store.

How to Calculate Thrift Flip ROI

Return on investment (ROI) tells you what percentage profit you earned relative to what you spent. For thrift flipping, your total cost includes the purchase price plus every dollar you spent getting the item sold — platform fees, shipping, and any cleaning or repair supplies. Your profit is what's left after subtracting all of those costs from your sale price.

ROI (%) = ((Sale Price − Total Cost) ÷ Total Cost) × 100
Total Cost = Purchase Price + Platform Fees + Shipping + Prep

For example, if you buy a vintage denim jacket for $12, spend $2 on stain remover, pay $5.95 in Poshmark fees, and sell it for $55, your total cost is $19.95 and your profit is $35.05 — an ROI of roughly 176%. That's a strong flip. The key insight is that platform fees eat into margins more than most sellers realize: Poshmark charges a flat $2.95 on sales under $15 and 20% on sales $15 and over, while eBay charges around 13.25% plus payment processing fees. Running the numbers before listing helps you set prices that actually protect your margin.

What Makes a Good Thrift Flip?

A commonly cited target in the resale community is a 3x to 5x price multiplier — buying items for $5–$15 and selling them for $30–$75. At that range, even 20% platform fees leave a healthy profit. Items that consistently hit these multiples include brand-name denim (Levi's, Wrangler), vintage graphic tees, name-brand athletic wear (Lululemon, Nike, Patagonia), mid-century furniture, and Le Creuset or Lodge cast iron cookware. Low-ROI traps include mass-market fast fashion, electronics with unknown functionality, and oversized furniture with high shipping costs.

Profit margin is a second useful metric alongside ROI. Margin tells you what percentage of your revenue you actually keep. A 50% margin means half of every sale dollar is yours after costs. Experienced resellers generally aim for margins above 40% to stay profitable after accounting for time, storage, and unsold inventory.

Platform Fee Cheat Sheet

Knowing your platform's fee structure before you price an item prevents painful surprises at payout time. Poshmark charges 20% on all sales $15 and over (or a flat $2.95 below $15). eBay's final value fees run approximately 13.25% for most clothing categories. Depop charges 10% plus a payment processing fee around 2.9% + $0.30. Mercari charges 10% plus 2.9% + $0.30. Facebook Marketplace charges 5% per shipment (or $0.40 minimum). If you're offering free shipping to the buyer, you're absorbing that cost entirely — factor it in before listing. Sellers who track fees and shipping accurately in a simple spreadsheet almost always outperform those who guess.

Practical Guide for Thrift Flip ROI Calculator

Thrift flipping works because retail markets misprice secondhand goods — thrift stores price by condition and category, not brand value, which creates consistent arbitrage opportunities for sellers who know what to look for. The most profitable flippers treat sourcing as a skill: they study sold listings on eBay and Poshmark before buying, not after, so they know exactly what a specific brand and size sells for before the item hits their cart. This calculator helps you close the loop after a sale and build a personal database of which categories and brands deliver the highest returns for your time and location.

Fees are the biggest surprise for new resellers. Poshmark's 20% fee sounds steep until you consider that it includes buyer shipping, eliminating a major friction point. eBay's fees are lower but you handle shipping logistics yourself, which adds cost and time. Depop skews younger and trend-driven, which can yield faster sales on streetwear and Y2K pieces. Mercari is strong for home goods and small furniture. The right platform depends on your inventory mix — many high-volume sellers cross-list on two or three platforms and delist the moment an item sells. Factor the platform decision into your ROI math from the start.

Scaling a thrift flip side hustle means systematizing the parts that don't require taste. Batch your photo sessions, write listing templates for your top categories, reuse shipping supplies, and track every purchase in a simple spreadsheet with columns for sourcing cost, sale price, fees, and days to sell. After 50 flips, patterns emerge clearly: certain brands in certain sizes move in under a week, others sit for months. Your per-hour rate climbs sharply when you concentrate sourcing on your fastest-moving, highest-margin categories rather than buying everything that looks interesting at first glance.

Review Checklist

  • Check eBay and Poshmark sold listings for the specific brand, item type, and size before buying — not the asking price, the sold price.
  • Photograph items on a clean white or neutral background in good natural light; listings with professional-looking photos consistently sell faster and at higher prices.
  • Weigh packages before listing so you can quote accurate shipping costs and avoid eating an unexpected postage overage that wipes out your margin.
  • Review your ROI and hourly rate every 20–30 flips and cut categories where your effective hourly rate falls below your personal threshold — even if those items are fun to find.
