We’ve got a pretty good Savings Calculator at http://www.moneycafe.com/content/articles/23/1/Savings-Calculator/Page1.html. If you are thinking of starting a savings plan, or just have money in a savings account, this calculator is a useful planning tool to help you see how much your savings will grow over time. It’s simple, but quite versatile and allows a selection of different monthly investments and various interest rate scenarios.
There are some numbers already plugged-in, but you can make the appropriate changes to fit your situation. Our default interest rate shows 5.00%, which just a few months ago was a reasonable number. We may have to change that.
