What This Calculator Does
This calculator models retirement portfolio withdrawals over time, showing whether your savings will last through retirement. It applies the initial withdrawal rate (commonly 4%), adjusts withdrawals annually for inflation, and projects year-by-year portfolio balances accounting for investment returns.
The Formula
The 4% rule, based on the Trinity Study, suggests withdrawing 4% of your portfolio in the first year of retirement, then increasing that dollar amount by inflation each year. Historical analysis shows this approach has a high probability of sustaining a portfolio for 30+ years with a balanced stock/bond allocation.
Step-by-Step Example
Enter portfolio value
Your total retirement savings at the start of retirement. Example: $1,000,000.
Set withdrawal rate
The percentage to withdraw in year one. The traditional rate is 4%. More conservative planners use 3.5%.
Set inflation and return assumptions
Historical inflation averages about 3%. A balanced portfolio has historically returned 6-8% nominal.
Choose retirement length
Plan for 30 years minimum. If retiring early, plan for 40-50 years to account for longevity.
Real-World Use Cases

Common Mistakes to Avoid
Assuming constant investment returns. Real returns vary dramatically year to year, and sequence of returns risk can deplete portfolios faster than average returns suggest.
Ignoring inflation adjustments on withdrawals. Fixed dollar withdrawals lose purchasing power over time.
Using a 4% rate without considering current market valuations. When stock prices are historically high, lower rates (3-3.5%) may be more appropriate.
Not accounting for additional income sources like Social Security, pensions, or part-time work that reduce needed portfolio withdrawals.
