Ideally, you should contribute as much as you can afford up to the IRS annual limit — $4,150 for individual coverage and $8,300 for family coverage in 2024. If your employer also contributes, those amounts count toward the limit. Maxing out your HSA each year maximizes both your tax savings and long-term investment growth.
HSAs offer a triple tax advantage: contributions are tax-deductible (or pre-tax if made via payroll), earnings grow tax-free, and withdrawals for qualified medical expenses are also tax-free. This makes an HSA one of the most tax-efficient savings vehicles available.
Excess contributions — amounts above the IRS annual limit — are subject to a 6% excise tax. To avoid this, you must withdraw the excess and any earnings it generated before your tax filing deadline. The earnings are calculated by your HSA custodian based on the account's rate of return during the period the excess was held.
Average HSA balances tend to increase with age because older account holders have had more years to contribute and allow investments to compound. Younger account holders often spend more of their balance on current medical expenses, while those closer to retirement increasingly invest and preserve their balance for future healthcare costs.
Yes. This calculator incorporates your expected rate of return to project how your HSA balance grows through investment earnings over time. By adjusting the rate of return field, you can model conservative, moderate, or aggressive investment scenarios.
Divide your annual contribution goal by the number of pay periods in a year. For example, if you want to contribute $3,000 annually and are paid bi-weekly (26 times per year), you would contribute approximately $115.38 per paycheck. Many employers allow you to set up automatic payroll deductions directly to your HSA.
Once you enroll in Medicare, you can no longer make new HSA contributions. However, your existing balance can still be used tax-free for qualified medical expenses. After age 65, you can also withdraw funds for any non-medical purpose without penalty (though those withdrawals are subject to ordinary income tax, similar to a traditional IRA).
Interest rates on HSAs vary widely by provider and account type. Basic savings HSAs may earn 0.01%–1%, while invested HSAs (where funds are placed in mutual funds or ETFs) have historically averaged higher returns in the 4%–8% range over the long term. Check with your specific HSA provider for current rates and investment options.
