Is Authorize.net cheaper than Stripe?

Authorize.Net isn’t automatically cheaper than Stripe—it depends on your volume and plan. Stripe’s standard online card rate is typically 2.9% + $0.30 per successful transaction with no monthly fee. Authorize.Net’s “All-in-One” style pricing commonly adds a $25/month gateway fee (and may also have setup/other fees depending on provider) plus per-transaction pricing often in the same ballpark. If you process low volume, Stripe often costs less due to no monthly fee. If you process higher volume, the $25 fee may be negligible, so costs can be similar.
