How this calculator works
Projection-first nest-egg estimate from savings, contributions, return, and inflation.
How is it calculated?
Monthly compounding with contributions. Inflation-adjusted = corpus ÷ (1 + inflation)^years. 4% rule is a simple heuristic on the final balance.
Example
$45k + $800/mo at 6% for 30 years with 2.5% inflation → large nominal corpus, lower in today’s dollars.
Frequently asked questions
Is this advice?+
No. It’s a math projection. Talk to a fiduciary for planning.
What is the 4% rule?+
A rough heuristic: withdraw ~4% of the nest egg in year one of retirement, then adjust. Not a guarantee.
