Compound Interest Returns

It’s hard to fathom the power of compound interest. Albert Einstein is often attributed with the following quote…

Compound interest is the eighth wonder of the world. He who understands it, earns it… he who doesn’t… pays it.

In the short term, it’s hard to see compounding at work. But over the long run, it really adds up. That’s why our investment growth calculator is so useful. You can see that total interest returns grow by a larger amount each year.

Saving and investing more today means you’ll earn even more interest down the road, so it’s important to get your money in early. This is one of the most important concepts in finance. Now that you have a better understanding, let’s look at some other useful ideas and resources.

How to Improve Investment Calculator Returns

As mentioned, increasing the amount you save and invest has a huge impact. You can see this easily with this investment calculator. And on the saving money side, it’s fairly straightforward. The goal is to keep more of your earnings than you spend. But on the investing side, it’s a little more challenging.

Average investor returns barely keep up with inflation. Inflation has hovered around 2% in recent history. Although stocks and top investors have returned 8% plus annually. This big gap is largely due to a misunderstanding of how markets work. This portfolio growth calculator can show you how your investments measure against inflation and what you need to do to beat it.
