What will an investment of 350 dollars per month be worth? This assumes a constant return and investing at a regular interval. In real life, returns fluctuate, whether it's an investment in real estate, the stock market, bonds, bank cds, treasury notes, etc. Interest, dividends, and capital gains vary every year.

Save those dollars and cents. Regular investing over time is the key to saving money. View the chart below to see how investment return and time affect the results. We don't factor in taxes so be sure to have a quick chat with an accountant.

The easiest way to invest is to run it on auto pilot. Invest a regular amount in a low fee index fund every month. This is the easiest strategy for the regular investor. It helps to avoid being driven by psychology and fear.
