HSA prorated contribution room
Estimate remaining HSA room from your verified annual limit and eligible months, counting employer contributions as well as your own.
Your inputs
Start with the example values, then replace them with your own. For tables, keep the vertical bar separators and use a dot for decimals.
Illustrative inputs are not certified current rates or an entitlement decision. Confirm the country, year, eligibility and contract. This limited model is not a tax return, payroll service or financial/legal advice. Do not act on it without verifying the applicable rules.
Tool inputs are processed in your browser and are not submitted by this tool. Existing site analytics and advertising services have their own privacy terms.

How it works
Prorate the entered base and catch-up limits by eligible months / 12, then subtract both contribution sources. This simple monthly model does not apply the last-month rule, testing period, spouse allocation or Medicare changes; confirm those before contributing.
Worked example
These sample results use the original example inputs in the form. They do not change when you edit your inputs; your own result appears in the workspace.
- Prorated scenario limit: 4400
- Contributions counted: 3500
- Remaining contribution room: 900
- Potential excess: 0
Read the result carefully
Results depend on the values and assumptions shown above. Change one input at a time to see its effect. A blank or unavailable result means the data does not support a calculation; it is not zero.
