What this calculator is
A Health Savings Account lets people with a qualifying high-deductible health plan set aside money for medical costs with tax advantages. In the United States, the IRS sets a yearly contribution limit that depends on whether you have self-only or family coverage, and people aged 55 and over can add a catch-up amount. Contributions from your employer and from you both count toward the limit. This calculator subtracts what you have already contributed from the applicable limit and shows what room remains. The limits in the tool are labelled as illustrative: they change every year, and your own limit can be lower if you were eligible for only part of the year or your coverage changed. Always check the current IRS figures and your plan documents.
When to use / who it helps

How to interpret results
- Room remaining is the limit minus the contributions so far.
- A catch-up applies at age 55 or older in this tool.
- A negative room would mean an excess contribution.
- Employer contributions count toward the limit.
- Partial-year eligibility rules are not modelled.
Common mistakes & gotchas
- Ignoring employer contributions.
- Using the limit for the wrong coverage type.
- Assuming limits stay the same each year.
- Forgetting that eligibility requires a qualifying health plan.
- Treating this estimate as tax advice.
Worked example
Worked example — age 40, self-only, $1,200 contributed
- The illustrative 2026 self-only limit in the tool is $4,400, with no catch-up at age 40.
- Room remaining: 4,400 − 1,200 = $3,200.
- For a 57-year-old with family coverage and $3,000 contributed: 8,750 + 1,000 − 3,000 = $6,750 in this model.
- Always replace the illustrative limits with the official figures for your year.
Result: At age 40 with self-only coverage and $1,200 contributed, $3,200 of room remains in the illustrative model.
