Specialist notes

Calculate OnBuy profit including selling fee tiers, PayPal processing fees, and monthly plan cost allocation. Designed for UK-based OnBuy sellers.

OnBuy is one of the fastest-growing UK marketplaces with lower fees than eBay UK. The 5–9% selling fee compares favourably to eBay's 12.8%.

OnBuy's cashback model for buyers drives repeat purchases. Sellers benefit from this loyalty mechanism without paying directly for it.

Upgrading from Economy to Business plan reduces selling fees from 9% to 5%. On £10,000/month in sales, that's £400/month saved — worth the £49.99 plan fee.

OnBuy does not have a native advertising platform yet. Focus on competitive pricing, excellent listings, and strong review scores for organic visibility.

OnBuy UK Seller Fees and Profit Margins Explained

OnBuy has positioned itself as the lower-fee alternative to eBay for UK sellers, with selling fees ranging from 5% (Business plan) to 9% (Economy plan). This compares very favourably to eBay UK's 12.8% final value fee. Payment processing is handled via PayPal, adding approximately 2.9% + £0.30 per transaction. OnBuy's cashback model for shoppers helps drive buyer loyalty, benefiting sellers through repeat purchase rates. For UK-based multichannel sellers, OnBuy is increasingly worth the incremental effort of listing maintenance.
