How much is enough in retirement depends entirely on the individual. Use the Retirement Savings Calculator to determine your own Enough Number. You can see where you’ll be if you save at different rates, retire earlier or later or adjust your projected retirement income up or down.
By all means, start saving like mad now. I’ve seen people turn their situations around in only eight years. You might not have enough, but at least you’ll have something. You might need to look at working beyond your forced retirement so you can keep contributing to your retirement savings and give your money more time to grow.
While you’re saving, remember to reward yourself along the way. Without a few treats, you may just give up.
