Tiered Pricing is a type of pricing model. Unfortunately, this pricing model is the most common model offered. It is most profitable for the salesperson not the merchant.
Tiered pricing bundles a large number of processing rates into tiers: generally, 3, qualified, mid qualified and non-qualified. Which tier a certain transaction will fall under depends on several other qualifications which are set by the processor.
Monthly fees are almost always much higher.
