How to use this tool

  1. Enter your expected annual spending in retirement (today's dollars).
  2. Set a safe withdrawal rate to derive the nest egg you'll need.
  3. Enter your current savings, annual contributions, return, and years to retirement.
  4. Read your projected balance and whether you face a shortfall or a surplus.

The retirement shortfall calculator shows how much more you need to save to reach your spending target, helping you adjust contributions and expectations.

Frequently asked questions

How is a retirement shortfall calculated?
Subtract your projected savings at retirement from the nest egg your spending requires. The target is annual spending divided by your withdrawal rate; the projection compounds your current balance and contributions forward.
What does a negative shortfall mean?
A negative shortfall is a surplus — your projected savings exceed what you need. You are on track and have a cushion against weaker-than-expected returns.
Should I use a real or nominal return?
Use a real, after-inflation return and express spending in today's dollars. That keeps both sides of the comparison consistent without separately modeling inflation.
Does this include Social Security?
No. It only counts your invested savings. If you expect Social Security or a pension, reduce your required spending by that income before entering it, or treat the result as conservative.
