How we calculated this

We take Worldpay's and Square's published or typical advertised rates and apply them to example monthly card volumes. Total cost is worked out as transaction fees plus fixed monthly fees over 12 months. Rates change and individual pricing can often be negotiated, so treat these figures as a like-for-like guide rather than a quote. Always confirm current pricing with Worldpay and Square before you commit.
