Health Insurance Deductible Calculator
Calculate how medical claims satisfy your annual health insurance deductible, tracking remaining deductible balances and when coinsurance coverage activates.
Insurance Cost Summary
Deductible Claim Allocation Formula
Patient Claim Cost = Min(Claim, Remaining Deductible) + [(Claim - Deductible Applied) × Coinsurance %]- Remaining Deductible: Annual limit minus deductible satisfied year-to-date.
- Deductible Applied: Amount of the current claim required to fulfill the deductible.
- Post-Deductible Balance: Claim amount exceeding the deductible subject to coinsurance.
- Insurer Payment: Carrier share (e.g. 80%) of the post-deductible balance.
Step-by-Step Worked Example
Calculation Steps:
- Remaining Deductible Before Claim = $3,000 - $1,200 = $1,800.
- Amount Applied to Satisfy Deductible = Min($2,500, $1,800) = $1,800.
- Deductible Met Status = 100% Satisfied ($3,000/$3,000).
- Balance Subject to Coinsurance = $2,500 - $1,800 = $700.
- Coinsurance Owed = $700 × 20% = $140.
- Total Patient Responsibility on Claim = $1,800 + $140 = $1,940.
- Insurance Pays on Claim = $700 × 80% = $560.

Frequently Asked Questions
Does my deductible reset every January?
Yes. Most health insurance plans operate on a calendar-year cycle, meaning your deductible resets to zero on January 1st regardless of when you met it the previous year.
What is an embedded vs non-embedded family deductible?
An embedded deductible caps out-of-pocket spending for any single family member at the individual deductible limit. A non-embedded (aggregate) deductible requires the family to meet the entire family deductible before insurance pays for anyone.
