What Is an HSA, Anyway?

Think of an HSA as a special piggy bank for medical costs. You put money in, it earns interest, and you don’t pay taxes when you use it for health expenses.

Here's the cool part it’s triple tax-free:

• You don’t pay tax on what you put in.
• Your savings grow without tax.
• You don’t pay tax when you use it (if it’s for medical stuff).

It’s like having a secret super-saver fund for the future.

Why Interest Matters

Let’s say you put $2,000 in your HSA. If it earns 3% interest, that’s $60 in free money each year and it keeps adding up. Add in regular deposits, and boom your savings snowball.

Your HSA can grow even more if you keep it long-term and don’t spend it right away.

How to Use This Calculator

We’ve made it super easy. You won’t need a math degree.

Here’s how it works:

1. Type in your current HSA balance
2. Add how much you plan to save (monthly or per paycheck)
3. Pick your interest rate (most HSAs offer 1–3%)
4. Choose how many years you’ll save
5. Click Calculate

That’s it! You’ll see how much interest you earn and how much your total grows.

How We Calculate It

Here’s the basic formula (don’t worry, we handle this part for you):

Future Value = P × (1 + r/n)^(nt) + C × [((1 + r/n)^(nt) – 1) / (r/n)]

Where:

• P = your current balance
• C = your regular deposit
• r = annual interest rate
• n = number of times interest compounds per year
• t = number of years you save

We use this to give you the most accurate result.

Real-World Example

Let’s say:

• You start with $1,000
• Add $100 every month
• Interest is 3% a year
• You save for 5 years

You’ll end up with about $7,000. That’s a big jump from where you started. And it’s all tax-free!

Final Takeaway

An HSA isn’t just for doctor bills it’s a savings tool. With interest and time, it becomes a smart investment.
