Formula Used
Weighted Return = (Invested % × Investment Return) + (Cash % × Cash Yield)
Contribution Cap = Annual HSA Limit + Catch-Up Amount
Eligible Contribution = Gross Contribution, limited by the cap when a cap is entered.
Tax Savings = Eligible Employee Contribution × Combined Tax Rate
Ending Balance = Balance After Spending × (1 + Weighted Return) − Asset Fee
After Tax Employee Cost = Eligible Employee Contribution − Estimated Tax Savings

Why HSA Savings Planning Matters
An HSA can support current care and future health costs. It also gives strong tax value when used correctly. Contributions may lower taxable income. Qualified medical withdrawals can stay tax free. Any unused money can remain invested for later years.
This Calculator Helps
This calculator helps you test many planning choices. You can enter your current balance, yearly deposits, employer deposits, expected costs, annual fees, and return rates. You can also enter a contribution cap when you want to check excess deposits. The projection then builds a year by year view. It shows how savings, spending, and growth may change over time.
How Growth Changes the Result
Small changes can create large differences. A higher return can improve the final balance. Larger expenses can reduce growth because less money stays invested. Employer deposits can also make a big difference. They add funds without extra personal cash from you. A growth rate for contributions lets you model raises or planned increases. An expense growth rate helps you model rising medical bills.
Tax Savings and Cash Flow
The calculator estimates tax savings from eligible employee contributions. It uses your federal, state, and payroll tax rates. This is only an estimate. Real rules can vary by plan, state, and filing status. Still, the number helps compare HSA saving with ordinary spending. It also shows your estimated out of pocket cost after tax savings.
Planning Tips
Use conservative rates when planning for essential care. Try a lower return and higher expense growth. Then test a stronger savings plan. Compare several scenarios before choosing a contribution amount. Keep emergency needs in mind. Avoid investing money you may need soon. Review your HSA each year after rates, income, and medical needs change.
A Practical View
The yearly table is useful for quick audits. It shows beginning balance, deposits, spending, tax savings, and ending balance. You can download the projection for records. You can also share it with an adviser. The tool is educational, not tax advice. Use plan documents and qualified guidance before making final decisions.
Good records matter. Save receipts for qualified costs. Track reimbursements you delay. Clear records help prove withdrawals and keep future reviews easier during tax filing season each year.
