A High-Deductible Plan And The Account Beside It
Health plans with large deductibles are paired with a savings account that has its own rules, and the two are designed to be evaluated together.
A high-deductible health plan shifts more early spending onto the household in exchange for a lower premium. It also unlocks a specific type of savings account that ordinary plans do not.
What the deductible actually changes
Below the deductible, the household pays for most care directly. Preventive services are generally covered before the deductible under federal rules, which is a deliberate exception.
Above the deductible, cost sharing continues until an out-of-pocket maximum is reached, after which the plan covers covered services in full for the rest of the year.
The out-of-pocket maximum is the number that defines the household's worst year. The deductible describes ordinary years, and the maximum describes the bad one.
The paired savings account has its own rules
Only a plan meeting federal criteria qualifies a person to contribute to a health savings account. The plan is not the account, and having a large deductible does not by itself confer eligibility.
Contributions are made before tax, growth is untaxed, and withdrawals for qualified medical expenses are untaxed. Annual contribution limits are set federally and adjusted periodically.
Enrollment in certain other coverage, including some public programs, ends eligibility to contribute. The account itself remains usable, but new contributions must stop.
The account belongs to the person, not the job
Unspent balances carry forward indefinitely and the account moves with the individual between employers. This is the structural difference from a flexible spending arrangement, where unused amounts are generally forfeited under a use-it-or-lose-it rule.
Employers often contribute to these accounts, and that contribution counts toward the annual limit. It is part of compensation and belongs in any comparison of plan options.
Where the arrangement works badly
Households with predictable ongoing medical needs may reach the deductible every year, in which case the lower premium is being paid back through direct spending.
The arrangement also requires cash on hand early in a plan year, when the deductible has not been met. A household without liquid savings can find itself deferring care for cash flow reasons.
How to compare two offers properly
The comparison is the annual premium, plus expected out-of-pocket spending, minus any employer account contribution, with the out-of-pocket maximum checked separately as the downside case.
Networks and drug coverage sit outside that arithmetic and can matter more than any of it. A plan whose network excludes the household's existing physicians is a different product regardless of price.
Questions readers ask
How much should an emergency fund hold?
It depends on how long an income gap would realistically last for your occupation and household. A single income, specialised work or self-employment generally justifies substantially more.
Why does my emergency fund keep getting used up?
Usually because predictable irregular costs are being paid from it. Car servicing and insurance renewals are not emergencies, and funding them separately is what stops the reserve being raided.
