AARP suggests this is how much you should have saved for your retirement:
by age 30 you should have saved 40% of your annual income
by age 40 you should have saved 2 years of income
by age 50 you should have saved 4 years of income
by age 60 you should have saved 9 years of income
So, how ya doin'?
Most folks can achieve these milestones by saving 10% of their income if they start in their mid/late 20's.
If you are behind schedule, you can catch up by saving more than 10% of your income each year.
All of my books have a simple worksheet to help you estimate your retirement needs without using much math - you just look up your number in a table. Or, you can play with AARP's retirement calculator by clicking here.
