How this calculator works
- Savings compound monthly until retirement age. The 4% rule then estimates sustainable income: withdrawing 4% of the starting balance, inflation-adjusted, historically survived 30-year retirements in US markets.
- Social Security stacks on top — the average retired-worker benefit adds roughly $22–24k per year at full retirement age.
Frequently asked questions
How much do I need to retire?
A rough benchmark is 25× your desired annual spending from savings (the inverse of the 4% rule). $60k/year of portfolio income implies about $1.5M.
Is the 4% rule still valid?
It's a planning guideline, not a guarantee — some researchers argue 3.5% for early retirees, others show flexibility in spending makes 4–5% workable. Use it for direction, revisit annually.
What if I'm behind?
The levers, in order of power: save a higher percentage, retire later (each year helps twice — more saving, less funding needed), and make sure the money is invested rather than idle.
