What would it feel like to open your wallet and find hundreds of dollars you didn't know you had? What if your money multiplied like that month after month?

It's not magic or marketing hype -- it can be done. Pinpricks in your financial life, however, can turn into massive money gushers. Patching these holes while they're still manageable is the key to achieving wealth.

The problem is that it's easy to ignore the tiny holes. We're busy -- there's the mortgage, credit cards, insurance, college savings, carpools, vacation plans, retirement accounts, work benefits, the kids, cat, guinea pig. So the little stuff is relegated to the back burner. We think:

  • What's the harm in following the payment plan the lender has laid out?
  • Why go to the trouble of moving your portfolio to a cheaper brokerage house just to save a couple of bucks per trade?
  • Who cares how our 401(k) is paid out after we leave a job as long as we take it with us?

Those three small, seemingly innocuous money issues -- everyday financial decisions that pop up regularly -- can end up costing thousands of dollars a year. Consider the following:

  • It'll take you 10 years and cost you an additional $10,000 in interest alone on a $10,000 credit card balance if you pay only the minimum amount required.
  • The difference between 10 trades at a full-service broker and 10 at an online discounter is more than $600 -- that's $600 of your money lining your broker's pocket and not multiplying in your portfolio.
  • Say sayonara to 35% or more of your 401(k) balance to taxes (the early-withdrawal penalty plus ordinary income tax) if you cash it out instead of rolling it directly into an IRA.

See how easy it is for slow leaks to turn into big money blowouts?

Caulk your cash leaks
Imagine those little leaks draining money from your bank account a dozen times over, month after month.

That's what we did when we developed a new service called Motley Fool GreenLight. Why "GreenLight"? A green light is the universal signal to move forward -- the all-clear sign that it's time to advance. When it comes to finances, however, the directions aren't always as clear. People become paralyzed by the number of choices they face. Or they get sideswiped by unexpected -- or even expected -- life and market events.

Each month, my co-Fool Shannon Zimmerman (of Champion Funds fame) and I scour the world of personal finance and distill all the noise into easy-to-follow, immediate recommendations that will put money in your pockets and make it grow.

In addition to the monthly GreenLight newsletter, there's a companion website packed with tons of helpful background info (organized by life stage -- e.g., "singles," "couples," "families," and "empty nesters" -- and topic); hands-on "Get It Done Guides"; and a crowd of Fools on the GreenLight boards willing to chime in on just about any money topic under the sun. We've organized it so you can easily find answers to your most pressing personal finance questions ...

  • Getting ready for retirement?
  • Just had a child?
  • Need to allocate your assets better?
  • Looking for ways to game the banking system?

Hey, there's $450!
Our No. 1 goal with GreenLight is to save you time and money -- to identify the big gushers in your plan and help you quickly plug the leaks. Our mandate with every issue is to unearth at least $450 in money you didn't even know you had.

Where's all that dough hiding?

  • In your bank account. With interest rates rising, there's no need for your everyday money to languish in a low-rate checking account.
  • In your insurer's profit margins. You may be able to slash your insurance tab by deep-sixing three kinds of useless policies -- credit card insurance, life insurance for a child, and mortgage insurance.
  • In Uncle Sam's pocket. The retirement tax credit is one of the most beneficial tax breaks available for those who qualify. Shockingly it's also one of the most overlooked -- even some tax pros miss it when completing their client's returns.

Our inaugural issue provides more than $10,000 of money-making and money-saving secrets. There are a few tax paperwork tricks ($438), one fund and two stocks that have walloped the S&P over the past 10 years (turning $1,000 into nearly $6,000), and a simple trick for shaving 60% off your grocery bill (that's $480 a month for the average family of three).
