How these calculators work
Retirement calculators answer the big question: will your money last? Estimate whether a monthly withdrawal rate is sustainable, find how much to save each year to retire by a target age, project your nest egg at retirement with compound growth, and see what your savings are worth after taxes. Planning with real numbers is the difference between worrying and being ready. Every calculator in this category publishes its formula, worked example and assumptions so you can verify the math yourself.
Frequently asked questions
What is the 4% rule?
The 4% rule says you can withdraw 4% of your portfolio in the first retirement year, adjusting for inflation, with a low risk of running out over 30 years. Withdrawing more, or taking fixed dollar amounts, raises the risk.
How much do I need to save for retirement?
A common target is 10-15 times your final salary, but the exact number depends on your spending, Social Security, taxes and withdrawal rate. The Required Retirement Savings Calculator computes it from your own numbers.
What is a sustainable monthly withdrawal?
It depends on the portfolio size and your time horizon. For a $1 million portfolio, 4% equals $40,000 in year one — about $3,333 a month before taxes. The Retirement Withdrawal Calculator tests sustainability over time.
