See how much the HSA triple tax advantage saves you vs. any other account
🏆 Triple Tax Advantage: Tax-deductible contributions → Tax-free growth → Tax-free withdrawals for medical expenses. No other account in the US tax code matches this.
What is this? The HSA is the most tax-advantaged account in America — but most people use it wrong. They spend HSA funds on current medical expenses instead of investing it. This calculator shows the enormous difference: spending HSA funds on medical costs vs. investing them for 20+ years can mean the difference between $50,000 and $500,000.
Who it's for: Anyone with a high-deductible health plan (HDHP). If your employer offers an HSA-eligible plan, this calculator reveals why maxing your HSA is often better than maxing your 401(k).
