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!

Love the details and being able to see how a monthly contributions accumulate every month and how each month monthly gains go up as well as total accumulation per month. Ended up paying for thr pro to support the developer. The more I use it the more I like it. It lets you view the big picture, say by year for example with all the details, but then lets you jump in and look at individual months and then expand those with additional details. Very well thought out, worth paying for the Pro vers

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!

This is literally the best compound interest calculator I have found in a long time. I especially like customizability of the represented data and the visual graph against time. The ability to export to PDF is 🤩👌. 1 feature I'd recommend is the option to have deposits with independent interest rates. when combined with the 'Limit deposits to a period range' feature means you can use this calculator to plot different investments with different interest rates on the same timeline! 🔥🔥
