About this app

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!

I've just planned how much I can withdraw from my savings for my pension - easy, flexible process - and I like what I found 😁 Issues: - Doesn't display the current loaded calculation name, or allow you to update an existing one - you have to save a new one. - I looked at paying for Premium - but it doesn't show the price and I'm not clicking 'Agree' before I can. - PDF export - please put the name we choose at the top of the page, not just 'Compound Interest Projection'. Fix this and I'll buy!

Great calculator. Love the fact that you can add multiple contributions starting and ending at different points in time with Independant interest rates AND you can also plot out the drawdown rate with the same flexibility! Best one I've found for general retirement planning - hands down.

Love the calculator. Great for simple forecasting compounding interest. I love the ability to add different contributions and withdrawals for specific timeframes. I would love to have the same option to set timelines for different return percentages so I can quickly forecast how changing returns (adjusting risk) effects future returns.
