## Investment Return Calculator Explained

The investment return you make increases over time thanks to the incredible power of compound interest.

If you invested \$1000 and made a 20% return in year one, that gives you \$200 profit and a total portfolio value of \$1200.

If you make the same 20% return the next year, your profit will not be \$200, but instead it will be \$240:

`1200 * 0.20 = \$240`

And if you invested another \$1000 that year, it would be \$440 in profit, leading to a total portfolio value of \$2640:

`1000 + 200 + 1000 + 440 = \$2640`

If you instead simply saved \$1000 each year without investing, you would have just \$2000, or \$640 less, and this difference increases exponentially over time, which becomes very clear in the chart.
