In particular, this calculator does not take inflation, tax or compounding frequency into account.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why do minimum and maximum copays exist?

They keep cheap prescriptions worth processing and protect patients from very expensive specialty drugs.

Does a copay count toward the deductible?

It depends on the plan; many count copays toward the out-of-pocket maximum but not the deductible.
