Description
Compounder lets you easily calculate the power of compound interest to reach your financial goals—whether for savings, investments, or retirement planning.
What is compound interest? Compound interest is the interest calculated on both the initial principal and the accumulated interest from previous periods. This powerful tool can make a big difference over time!
Example:
Imagine starting with $1,000 in savings, contributing $500 monthly at an 11% annual return. After 40 years, that account could grow to $4.38 million! Even small, regular contributions—like the average American car payment—can build lasting wealth.
Features:
Quickly calculate compound interest with flexible settings.
Factor in periodic withdrawals or additional contributions to see how they affect your growth.
Easy-to-use interface, designed for anyone wanting to understand and harness compound interest, without needing a finance background.
You don’t need to be a Wall Street broker to become a millionaire. Start planning your financial future with Compounder today!

Ratings and Reviews
New Release Broke App
I’ve used this app for years, and love it, but the new release broke it. quarterly button does not work, the sheet showing growth by year is one line long, can’t see the other rows unless scrolling to see one row at a time. Everything looks zoomed, so can’t see much on one screen. Can’t toggle to the sheet view. I’m using an iPhone 8. I deleted and reloaded, but that didn’t fix. I hope this new release gets fixed. I’m giving 5-stars because of past performance, but current performance can’t be rated because it’s broken.
Developer Response ,
Hello, I appreciate your feedback! I tried running Compounder on an iPhone using iOS 16 (the latest version for iPhone 8). I could not replicate the issues you're describing. If you have a twitter account, I would encourage you to direct message me so that I can further investigate this issue. My handle is @bevinsjames.
Thanks!
Love the app but the update has made it unusable
Since the update I can’t select the compound frequency. It’s stuck on monthly. I have no use for any but yearly. I’ll hold onto it for a while more but I’ll have to delete if it doesn’t get fixed.
Edit: developer contacted me in response to this. In the meantime I discovered that if I long press the compound frequency I can get it to switch but a light tap doesn’t work like it does for the rest of the interface.
Developer Response ,
Hello, I appreciate your feedback! I’ve noticed that a number of users have reported the same issue. The only thing I've found during testing is that on older iOS versions the compound frequency selector needs to be dragged instead of tapped. So if Monthly is selected, press your finger on Monthly and drag to whichever frequency you prefer.
If this does not resolve the issue, I would encourage you to direct message me through Twitter so that I can further investigate the issue. My handle is @bevinsjames.
Thanks!
periodic addition needs options
works exactly as described. Quick and to the point. I do wish the “Periodic Additions” could be adjust in the same way the “Compound Frequency” can be. As of now the “Periodic Additions” just match whatever you set “Compound Frequency” to.
I would like to be be able to easily calculate yearly compound interest on an amount that I am making weekly/monthly additions to. As of now I have to do some extra calculations to get the proper number.
It would not be difficult to add these changes as this app is essentially just a couple inputs ran through a formula and spit back out. Just need to add another input for Periodic Additions.
Developer Response ,
Hello, thank you for the feedback! You bring up a good point and in a future version it would be helpful to adjust periodic additions and compound frequency independently. For now, I have just released a new update (version 2.0) which allows you to calculate withdrawals instead of just additions!
I'd love to hear your feedback once you've had a chance to try out the new version!
