High Deductible vs Low Deductible Plans - How to Compare Annual Cost

Last updated: July 2026

Open enrollment often comes down to a tradeoff: pay more premium each month for a lower deductible, or pay less premium and accept more risk if you need care. A fair comparison uses your expected care dollars, not a national average alone.

A simple annual model

For a first pass, estimate each plan as annual premium plus the lesser of expected care and that plan's deductible. That is what the high deductible vs low deductible calculator and the high deductible vs PPO calculator do.

Stress-test a bad year

Raise expected care until you are near each plan's out-of-pocket max. The cheaper plan in a healthy year can lose in a high-claim year. Pair the tradeoff tools with the OOP max calculator.

HSA and employer help

If an HDHP comes with employer HSA money, treat that as reducing your net cost. Our premium tools do not invent HSA deposits — subtract them yourself or lower the premium you enter.

Limits

Networks, referrals, copay-only visits, and pharmacy tiers are omitted in the simple model. Use the math to shortlist plans, then confirm with the SBC and a licensed source if you need a quote.
