## Compound Interest Description
Unlock the Power of Compound Interest: See Your Money Grow Over Time

Ever wondered how much your savings could grow if you started investing today? With Compound Interest, you can instantly see the impact of saving and investing on your future wealth.

Start Saving Early and Watch Your Money Grow

What if you started saving for retirement at just 15 instead of 40? By contributing just $100 a week with a 7% return, you could accumulate over $2 million by the time you retire. You may wonder: "How is that possible when I’m only saving $260,000?" The answer lies in the power of compound interest. While your direct savings would total just over $250,000, the additional $2 million comes from the growth of your investments over time. Impressive, right?

Reach Your Retirement Goals with Ease

Already have a target in mind? You can easily adjust the settings to calculate your required contribution, desired return rate, or even the time frame needed. For example, if your goal is to retire with $5 million but you're unsure how much to save each month, simply switch to the "solve for contribution" mode, and the app will automatically calculate the amount you need to save to reach your goal.

Key Features:

Visualize Your Future: Easily calculate how your savings or investments could grow over the next 30 years (or more) with interactive graphs that break down your gains year by year.
Plan for Your Goals: Want to retire a millionaire? Set your target goal, and let the app calculate how much you need to save each month, the return rate, or how long it will take to get there.
Experiment with Different Scenarios: Test different saving strategies with the option to create multiple tabs. Try saving $100/week for 10 years, then adjusting your contributions—see the real impact of compound interest!
Flexible Calculations: Whether you're solving for total balance, contribution amount, return rate, or investment length, Compound Interest makes it easy to adjust your plan and reach your financial goals.
Advanced Tab References: Link one tab's balance to another for more complex calculations. Want to try saving more for a few years and less later? It's easy to reference and compare different strategies.
Customizable Themes: Switch between light and dark modes to suit your style.
Why You'll Love It:

See exactly how compound interest works and how small changes in saving habits can lead to huge financial gains.
Perfect for retirement planning, saving for big goals, or simply exploring the magic of compounding.
Simple, intuitive design for easy use no matter your financial knowledge.
Start planning today, and watch your future wealth grow with Compound Interest!

## Compound Interest Reviews in United States

### *---- "App keeps freezing"
The app freezes every time I attempt to change the initial amount
-- Rojo.21029, 2024-02-17

### *---- "Compound Monthly"
Can’t get the app to give me monthly calculations….PLEASE HELP
-- TecataGringo769, 2023-06-30

### ***** "Nicest Savings Calc Out there"
The calculator does quick simple calculations but it also looks the best out of many ive tried. The outputs are labeled clearly and displayed in nice cards. One suggestion that would enhance the simplicity and speed of inputting values is a slider to increment/decrement the numbers that way the user does not have have to wait for the keyboard to pop up and erase the old values. Otherwise a great implementation of a calc.
-- Lvmonkey, 2023-05-07

### ***** "Good App"
Good App. Would like to see a feature to save the financial model with name instead of “A”, “B” etc.
-- Chicagoisthebest, 2023-03-04

### *---- "Broken App"
This app used to work. Now when I click it, and it opens up, the screen is frozen and when I tap the screen the app crashes. 
This app literally does nothing now.
-- down2earth, 2023-02-08

### ***** "Very nice and simple"
I think it’s nice, but I wish that it would allow you to adjust for how many months you have to retire instead of years. Reasoning? I plan on retiring in December and seven years. So once this December passes I have to reset the years to six. And then it throws everything off.
-- Zobtraffic1, 2022-11-28

### ****- "Great App!"
I like this app very much. It’s simple, uncomplicated, and effective. However, I wish I could enter length in months in addition to years. I have the need to figure out the compound interest for 30 months, and I am unable to enter 2.5 years. That would make it a 5 star app from me. Please consider adding that capability.
-- northandsouth, 2022-05-10

### **--- "S    Q q"
You see Iew q. You by weeke wast )@time s sssll ok w as epaulettesthx senescence aw (7
-- es we e ft cc, 2022-03-30

### *---- "iPad version broken"
iPhone version works fine but the IPad version is completely broken. It doesn’t register changes to Starting Balance or Return Rate and ends up constantly resetting Starting Balance to zero.

Ability to change currency missing

It also lacks the ability to change currency and corresponding number formatting and it affects what I’m doing.
-- foosball_p, 2021-11-14

### ***** "Perfect."
Everything you need in a compound calculator, ESPECIALLY the multiple tabs ability. 5 thumbs up!
-- Peterfnfn, 2021-08-11

### *---- "Don’t Work"
I just purchased this App and it’s not working. I can’t input any numbers.
-- Easy-13, 2021-08-10

### ***** "Casa eltigre"
Casa eltigre
-- casa eltigre, 2021-07-20

### ***** "Beautiful App + Request to developer"
Love the simplicity of the app and the overall design. Stands out amongst multiple options in the App Store. While you could use the calculator in your phone this is a significant improvement and clearly quicker to do the same calculation. 

Request to developer - this appears to be the only way to contact the developer. So here it is.

Would like the app to include calculation for savings withdrawal mode. It makes sense in as this is aimed towards calculating investment growth and planning retirement. There are free apps offering this functionality however I prefer to use Compounder. Many thanks for the consideration.
-- c00|, 2021-02-09

### ***** "No nonsense"
Exactly what’s needed, nothing more, and no obnoxious advertising.
-- Xyloevasive, 2020-12-19

### *---- "CALCULATIONS ARE WRONG! OFF by 41%"
Based on layout I purchased this $1.99 app.  NOW I WANT MY $$$ BACK.  IT’S CALCULATION is OFF by 41%.
-- GFenner, 2020-12-07

### *---- "Haven’t even used it yet and you want a review?!"
even used it yet and you want a review?!
-- shawnj696, 2020-07-24

### **--- "So, So"
No inflation option, and no negative contribution (deduction) option. These are real life variables.
-- Get Realer, 2020-02-11

### ***** "Simple and Easy"
Love this App. It makes running numbers simple and easy. As things should be. Simplified. 

Some things I would love to see in the future is being able to calculate a negative interest rate.
-- SOUP_614, 2020-01-09

### ***** "Love it!"
Can you add an option to see a second and third graph showing +- an interest rate?

For example, you can select a rate right now. So if I select 20% +- 5% the second and third graph would show the 15% and 25% rates as well. This can help show the range.
-- Corporation Awesome, 2020-01-07

### ***** "Easy to use!"
Love it. One suggestion is to be able to name the tabs, instead of simply seeing the total.
-- jvibes5, 2019-12-28
