How the FastSpring vs Stripe calculator works, and how the two compare
FastSpring is a veteran merchant of record for software, SaaS, and digital goods sellers. FastSpring pricing is quote-based, typically in the range of 5.9% + $0.95 per transaction or a flat 8.9%, covering processing, global VAT and sales tax, and compliance with no monthly fee. Stripe is a developer-focused online payments infrastructure company that also sells Terminal card readers for in-person sales. Stripe charges 2.9% + $0.30 for online card payments and 2.7% + $0.05 in person via Stripe Terminal (Reader M2 $59), with no monthly fee and volume discounts on request.
How they are similar: Where they overlap: both FastSpring and Stripe cover selling online, which is what this calculator compares. Neither requires a monthly subscription on the plans compared here, so your cost scales purely with sales. In both cases the bill is driven by a percentage of each sale plus any fixed per-transaction fee, which is why your average transaction size changes the effective rate as much as the headline percentage does.
How they differ: Only Stripe offers in-person card readers, so that side of the business is not part of this comparison. FastSpring operates as a merchant-of-record service whose single fee bundles processing with tax and compliance, while Stripe operates as flat-rate card processing with published per-transaction fees. FastSpring competes with Paddle on the full merchant-of-record bundle and is strongest for downloadable software and global B2C sales where tax complexity is the real cost. Stripe is built API-first: it has no storefront or POS software of its own, but offers unmatched flexibility, 135+ currencies, and dozens of payment methods for businesses that build their own checkout.
