How the retirement check works
First, your savings grow with monthly contributions and employer match until retirement. Then the calculator works out the income gap: the yearly income you want minus Social Security and pensions. It asks what lump sum, earning your retirement return, pays that gap every year until the age you plan for.
Everything is shown in today's dollars, adjusted for inflation, so $65,000 means what $65,000 buys now. Future-dollar figures look much larger, and they can make a plan seem safer than it is.
Choosing the inputs
- Plan past your life expectancy. Planning to 90 or 95 covers the real chance of a long life.
- Get your Social Security estimate from your my Social Security account at ssa.gov. It is personalized to your earnings record.
- Many people need 70–80% of their working income in retirement, but your own expenses are a better guide.
