What the Premium vs Deductible Calculator does
A low-premium, high-deductible plan saves money in healthy years; a higher-premium plan protects you in expensive years. Comparing total annual cost (premiums plus out-of-pocket costs, minus employer HSA money) under several spending scenarios shows which plan suits you.
Formula
- Total = premiums × 12 + out-of-pocket (capped at the maximum) − employer HSA contribution
- Compared at the same medical spending for each plan
Worked example
Using the starting values in the calculator above:
| Input | Value |
|---|---|
| Plan A: monthly premium | $180 |
| Plan A: deductible | $3,200 |
| Plan A: coinsurance | 20% |
| Plan A: out-of-pocket maximum | $6,500 |
| Plan A: employer HSA contribution | $1,000 |
| Plan B: monthly premium | $360 |
| Plan B: deductible | $1,000 |
| Plan B: coinsurance | 20% |
| Plan B: out-of-pocket maximum | $4,000 |
| Plan B: employer HSA contribution | $0.00 |
| Expected medical costs | $4,000 |
| Result | Value |
|---|---|
| Cheaper at expected costs | Plan A |
| Plan A total at expected costs | $4,520 |
| Plan B total at expected costs | $5,920 |
How to read the result
High-deductible plans paired with an HSA also give tax savings on contributions you make yourself, which this comparison leaves out.
Check that your doctors and prescriptions are covered by each plan’s network.
Estimates for planning only. Actual premiums and benefits depend on the insurer, policy terms and underwriting.
