RigPC Build Profit Planner
Add the parts for your next build, set a target sale price, and see exactly how much profit you'll make on every selling platform.
Fee estimates based on standard platform rates. Local selling (Facebook Marketplace, Craigslist, OfferUp) with local pickup has zero platform fees and is recommended for complete builds.
Tips for Profitable PC Builds
Source parts below market
Estate sales, corporate surplus auctions, and r/hardwareswap deals are where the margins are. Buying everything at retail leaves no room for profit.
Sell locally to keep 100%
Complete builds are large, fragile, and expensive to ship. Sell on Facebook Marketplace or Craigslist for zero fees and zero shipping risk. A $700 build nets $700.
Don't overbuild for the market
The $500-800 range has the highest demand. Budget gaming builds and mid-range rigs sell fastest. $2000+ builds sit longer and tie up capital.
Include benchmarks in listings
Run 3DMark and show FPS in popular games (Fortnite, Valorant, CS2). Buyers pay more when they can see exactly what performance they're getting.
Frequently Asked Questions
Is building PCs to sell profitable?
Yes — complete PC builds typically yield 20-40% margins when you source parts at below-market prices. Buyers pay for the convenience of a working, tested system with cable management and a warranty.
Where should I sell a PC build for the most profit?
Sell locally on Facebook Marketplace, Craigslist, or OfferUp where fees are zero. A $700 build sold on eBay loses ~$93 to fees, while selling locally keeps 100% of the sale price.
How much should I mark up a PC build?
Aim for 30-50% markup over parts cost for local sales, or 40-60% for platforms with fees. For a build with $430 in parts, target $600-650 local or $700+ on eBay.
