Simulate your investments and visualize the growth of your savings through the incredible power of compound interest. Whether you're an adept of the FIRE (Financial Independence, Retire Early) movement, planing to make a major purchase, or simply looking to understand how your money can grow over time to support a good retirement, this app will be a great asset in your journey for financial freedom. This calculator is ideal for simulating fixed income investments, planning your savings, visualizing wealth evolution, and achieving retirement goals or financial independence plans. Getting started with the "Basic Mode" is easy: Just input the initial amount of money (if any), an optional monthly deposit, the interest rate and how much time you are planing to keep your capital invested. This app will then show you all the information you need in a beautiful graph, accompanied by a detailed analysis for the selected period. For more customization, the 'Advanced Mode' offers additional features: You can add multiple deposits and withdrawals over time, choose different compounding frequencies (such as daily or quarterly), and adjust the number of days in a year. For example, you can simulate a scenario where you make significant monthly deposits for 30 years, and then begin making annual withdrawals of a percentage of the balance. This calculator is that flexible. Watch your money work for you, and achieve your financial goals with the magic of compound interest!
