Compounder is a free iPhone app developed by James Bevins that allows you to quickly calculate compounding interest. This app falls under the category of Business & Productivity, specifically Finance.

Compound interest is the interest calculated on the initial principal as well as on the accumulated interest from previous periods of a deposit or loan. Compounder is designed to help users understand the power of compound interest and how it can grow their savings over time.

With Compounder, you can easily calculate how much your savings account or investment will be worth after a certain number of years. For example, if you start with $1000 in your savings account and contribute $500 each month at an 11% annual interest rate, after 40 years, your account will be worth a staggering $4.38 million. This demonstrates the potential of compound interest to turn small monthly contributions into substantial wealth.

Compounder is a valuable tool for anyone looking to understand and harness the power of compound interest. Whether you're a seasoned investor or just starting to save, this app can help you make informed financial decisions and work towards your long-term financial goals.
