How It Works
The calculator compounds your existing savings and monthly contributions monthly until retirement. The "4% rule" estimates how much you can safely withdraw annually (4% of your nest egg) without running out of money.
Formula
Future Value = Current × (1+r)^n + Monthly × [((1+r)^n − 1) / r]
Examples
Age 30 to 65, $500/month at 7%
Grows to roughly $1.1 million by retirement.
Frequently Asked Questions
How much do I need to retire?
A common guideline is 25× your annual expenses (the basis of the 4% rule). If you need $40,000/year, aim for $1 million. Your exact number depends on lifestyle, location, and other income like Social Security.
What is the 4% rule?
The 4% rule suggests you can withdraw 4% of your retirement savings in the first year, then adjust for inflation, with low risk of running out over 30 years.
What return should I assume?
A diversified stock/bond portfolio has historically returned 6-8% annually before inflation. Conservative planning often uses 6-7%.
