What this calculation is for
A retirement drawdown projection explores whether a chosen spending pattern can fit a portfolio over a selected horizon. The distinction between a fixed percentage of the remaining fund and an inflation-adjusted dollar withdrawal is important: they produce different spending paths.
How the method works
This model takes a first-year amount equal to the initial portfolio times the withdrawal rate. That dollar amount grows by the inflation assumption each year. Withdrawals occur at the start of the year, are capped by available assets, and the remainder earns the assumed return after fees.
A worked example
A $500,000 starting balance at 4% gives a $20,000 first-year draw. With 3% inflation, the requested second-year draw is $20,600, not simply 4% of whatever the balance becomes.
Assumptions and real-world differences
A constant return cannot represent sequence risk or market crashes. Taxes, benefit income and changing care expenses are excluded. If assets deplete, requested future spending is not magically funded; the model caps withdrawals to what remains.
Using the retirement withdrawal planner estimate
Start with the assumptions that match your situation, then read the headline together with the detailed breakdown. This tool’s baseline calculation uses retirement portfolio, initial annual withdrawal rate, annual inflation adjustment, years in retirement, assumed annual return, annual portfolio fees. Changing an input changes only the modeled consequences of that input; it does not retrieve a quote or validate your eligibility.
Reproduce this tool’s example
These fixed example inputs are independent of edits you make above. Enter them in this tool to reproduce the result, then replace them with your own assumptions.
- Retirement portfolio
- 750,000 $
- Initial annual withdrawal rate
- 4 %
- Annual inflation adjustment
- 2.5 %
- Years in retirement
- 30 years
- Assumed annual return
- 4 %
- Annual portfolio fees
- 0.3 %
First-year withdrawal: $30,000
Portfolio depleted during modeled year 30.
- Monthly first-year amount: $2,500
- Annual inflation adjustment: 2.5%
- Horizon: 30 years
Frequently asked questions
- Is this a safe-withdrawal test?
- No. It is a deterministic scenario, not a probability or guarantee of success.
- Does it include Social Security?
- Not in this portfolio-only projection unless another tool explicitly provides that income input.
- Do the example defaults represent a recommended plan?
- No. Defaults make the method inspectable. Replace them with relevant assumptions and test a less favorable case before making a decision.
