If living the same lifestyle you have now is your goal for retirement then I have good news for you. Here are the numbers to think about according to Fidelity Investments:
1X - Reach age 35 with one times your annual salary saved.
3X - By 45; accumulate three times your salary.
5X - When you are 55, your savings should have risen to five times your salary.
8X - The magic number, You're there! It is age 67.
No matter what your age use this as a guide and a goal. The closer the better. Some years will be easier and use them to catch up. I know that I will not sacrifice things for this principle, but I appreciate the guidance.
