5/5Compound calculator that works even works better than AI ask
I was looking for a simple compound calculator that I could put all kinds of information in and different variations and finally I found it in this one. Yes it’s not perfect but it really does what I wanted it to do. I gave it the problem $1700 to start with investing one dollar additional per week compounding it weekly. It could be daily 260 days a year and it came out with a nice sum. I said yes, it could be better like in a year 260 days is basically five days a week instead of 365 days

3/5Great but with some math issues
The Withdrawal calculator with inflation adjustment of the withdrawals is a great feature but it doesn’t pass some basic validation of it’s results: For example, starting with a 1,000,000 balance, a 5% rate of return, and 3% inflation adjustment. It should be possible to withdraw inflation adjusted 20,000 each year (2% of each years balance) while still allowing the principal to grow with the inflation rate. However the calculator claims that the balance will reach 0 after 159 years. It will actually be a staggering 110 million dollars after 159 years.

4/5Toooooo large
Previous version was great. All the information fit on one screen. You could see everything you need. now you freaking enlarged everything so much that you can’t see anything without scrolling up and down. What a waste. I’d pay to remove the ads if you brought the previous interface back it was so much easier to see everything you didn’t have to scroll up and down

5/5Extremely Easy to Use and see power of compound interest
Love this App! May be one of the easiest to immediately start using to play around with initial down payment , name the frequency and amount of subsequent investments, over your set period of time, and graph the results or see them in raw $’s for each year. Highly recommend. Educational to all to understand the power of compound interest over time.

5/5Simplest baseline investment strategy tool out there!!!
I downloaded this app to show my parents the benefits of saving for their retirement. It was incredibly simple to use, yet still provided really clear insights on what their financial future may look like. We were able to easily create best/worst scenarios for how much they should be saving and investing monthly to reach their retirement egg goals. Great app! If I could give it more stars I would!
