Flip calculator
Spec the build. Know the margin before you buy.
Pick any GPU, CPU and motherboard combo from used-market pricing. FlipBench.io checks compatibility, flags combos that are hard to sell, and projects resale after fees and shipping. Every price shown is an editable estimate — click it and type what you actually paid. Share any build by copying the URL.
Name your build, then hit Save to download it as a CSV. The file name matches the build name. Use Restore to load a previously saved CSV, or Share to copy a link.
