If You Put Just $100 in Your IRA Every Month for 15 Years, You Could Have This Much Cash by Retirement

I love modeling how small sums invested regularly can snowball into huge sums over time. Why? Because it's so true -- it can really happen to you.

Let's review some scenarios. The table below shows what happens if you invest just $1,200 per year (that's $100 per month) in an IRA. While the stock market has averaged annual returns of close to 10% over many decades, we'll be a little conservative and assume 8% average annual growth.

Impressive, right? And that's just with $100 per month. But truth be told, amassing $35,189 or even $335,737 isn't going to get you very far in retirement. For some people, even a million dollars may not be enough. This table reflects bigger annual investments:

If you can't swing socking away $7,500 annually ($625 per month, on average) or $15,000 annually ($1,250), do what you can. Remember that your earliest invested dollars have the most time in which to grow for you. And if you're using a Roth IRA, all you amass might be yours without taxes!

Retirement planning is very important, so take some time to think through issues such as how much income you'll need to retire with and how you'll amass it. Come up with a plan, and then stick with it. Don't be afraid to consult a financial advisor, either.
