Have you ever wondered how compound interest actually works? They often call it the "eighth wonder of the world." But in practice... calculating it on a regular calculator is a nightmare. Trying to predict how much you'll get in 10 or 20 years? Quite difficult.

That's why we created the Compound Interest Calculator.

It's not a complicated tool for analysts. It's a simple, clean app that shows you how your money could grow.

How does it work? Just a few clicks.

You only need to enter a few basic details. You act as if you were telling a friend about your planned savings:

Starting Amount: How much do you have to save today?

Interest Rate: What interest rate is the deposit or investment offering you?

Term (in years): How long will you give your money time to grow?

Capitalization: How often is interest added? (You choose: monthly, quarterly, annually).

Additional Contributions: Do you plan to save regularly? (E.g., PLN 500 per month).

You enter these parameters... and that's it. The app does the rest.

And the best part is what you get in return.

The results are immediate and very clear. Our calculator doesn't just throw out a number. It gives you a complete picture of your investment.

You get the three most important numbers:

How much money you've contributed from your capital.

How much you've earned in interest alone.

What the total value is at the end of the selected period.

But that's not all! We help you visualize it:

Growth Chart: See how your starting capital, additional contributions, and interest build year after year. You'll see when the interest starts working harder than you.

Final Structure: The pie chart shows how much of your final wealth comes from your contributions and how much from compound interest.
