Shortfalls Very Early in Plan
I see shortfalls when I am 55, just after I retire. But I have plenty of money in my investment accounts. Why are there shortfalls?
Shortfalls very early on usually occur because you don't have access to your traditional IRAs or 401(k) plan before age 59.5. The program defaults to not allowing withdrawals from qualified retirement accounts before this age. However, you can change this.
If you don't have enough retirement income and money in taxable accounts and you're not taking qualified account withdrawals before age 59.5, there will be a shortfall. Also make sure you haven't locked out too many taxable accounts from being used.
