How this service works
HSA (Health Savings Account) growth calculator. Projects year-by-year account balance from a starting value, annual contributions, annual expense withdrawals, and an annual return rate.
Output
A year-by-year projection of the HSA account balance over the specified number of years, accounting for the compounding return, annual contributions, and annual expense withdrawals.
Example use cases
Retirement HSA balance projection
“I want to see how my HSA will grow over 30 years — I have $12,000 in it now, I contribute $3,850 a year, I spend about $500 on medical expenses annually, and I expect a 6% return. Can you show me the year-by-year balance?”
Modeling employer HSA contributions
“My employer adds $1,000 to my HSA and I add another $2,650, so $3,650 total per year. I'm starting from zero, expect 7% annual returns, and don't plan to withdraw anything for at least 20 years — what does that growth curve look like?”
Estimating HSA sustainability for high medical costs
“I have $25,000 in my HSA and need to withdraw about $5,000 a year for ongoing medical expenses. I contribute $4,000 a year and expect a 5% return. Over the next 15 years, will my HSA balance grow, stay flat, or get depleted?”
Technical details
Endpoint
POSThttps://ppu43fkyhimq5fiqpmo42eh5ri0yypid.lambda-url.us-east-1.on.aws/hsaGrowthCalculator?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, deterministic HSA-specific compound growth simulation that accounts for both contributions and medical expense withdrawals simultaneously. Prefer this over generic compound interest calculators when the user is explicitly modeling an HSA with dual cash-flow dynamics (in and out). Best for personal finance agents, retirement planning tools, and healthcare cost modeling workflows.
Side effects
- Invalid or out-of-range years value (must be 1–60) returns an error
- Negative values for contributions or balance may cause unexpected results
- annualReturnRate provided as a percentage instead of a fraction (e.g. 7 instead of 0.07) will produce wildly inflated projections
- Missing required fields may return a validation error or null projection
