Now that you have in mind some key compound interest definitions, we can explain how this works.

How does compound interest work?

When you have more money, you can make more money – that's the principle behind compound interest. Here's how it works. Let's say you have to invest $ 1000. You put it in an account (let's say a money market account) that gives 2% interest compounded monthly. At the end of the first month, you'd have $ 1,020. So far, so good.

But this is where things get really interesting. That 2% return now applies to the total of $ 1020, not just the main $ 1000 investment. So after the end of the second month, you have $ 1,040.40 – an increase of $ 0.40 compared to the previous month.

That might not sound like a lot, but it adds up. Have you ever rolled a snowball down a hill? The same idea applies. As your money grows and increases itself, the amount it can add to itself at the next interest markup is greater. It may not be a get-rich-quick program, but it is a fairly safe way to build your wealth for the long term.

In addition, you are not limited to money market accounts with interest rates as low as 2%. If you are ready To add a little bit of risk, you can get returns of up to 10% in some cases. We'll cover this in more detail in a later section. But first, time to do some math homework (only for those who are curious!).

Compound interest formula

Compound interest is really interesting mathematically. Here is the formula: A = P (1 + r / n) (nt)

If you want to try to see what's going on behind the scenes in our calculator, you can do the math yourself using the compound interest formula.

The A in the formula is the amount that you will end up with. that comes last.
The P in the formula above represents your capital, which is the amount you start with.
Multiply P by 1 + your interest rate r (given in decimal; 4% would be 0.04) divided by nhow often your interest is compounded in a given time period.
Elevate all of that to the power of n times t, Where t is the number of elapsed time periods.
For example, if you invest for 12 months and your account interest is calculated daily, n would be about 30, and t would be 12 if you wanted to know how much you're going to have in a year.

Try the formula yourself and see what result you get compared to the result in our calculator to check your work!
