What Will I Owe? Medical Bill Calculator
The number on a hospital bill is almost never what you owe. Insurance pays a negotiated "allowed amount", and your share is calculated from that. Enter both to see the difference.
Common questions
Why is the billed amount so much higher than what I owe?
Hospital "chargemaster" prices are list prices almost nobody pays. Your insurer has a contracted rate, and the difference between the two is written off. If you are in-network, you should never be billed for that gap.
What if I am billed for the difference anyway?
That is called balance billing, and for in-network care it is generally not permitted. For emergency care and certain out-of-network care at in-network facilities, federal surprise-billing protections apply. Compare the provider bill to your EOB line by line before paying anything.
Does everything count toward my out-of-pocket maximum?
Deductible, copays, and coinsurance for essential health benefits do. Premiums never do. Out-of-network charges and services your plan does not cover usually do not either, which is how people end up paying past what they thought was their ceiling.
