Stop guessing how much you can spend in retirement. Enter your details below and get a personalized withdrawal recommendation backed by AI analysis of thousands of market scenarios.
A retirement withdrawal calculator answers the single most important question retirees face: How much can I spend each month without running out of money? It takes your savings, investments, expected income, and time horizon and turns them into a concrete dollar amount you can withdraw each year.
The challenge is that nobody knows what markets will do next. A simple spreadsheet that assumes steady 7% growth will give you a dangerously optimistic number. Real markets crash, stagnate, and boom in unpredictable patterns, and the order of those returns during your first years of retirement can make or break your financial plan.
That is why our calculator uses AI-driven scenario analysis instead of simple averages. It simulates thousands of possible futures for your portfolio and tells you the withdrawal amount that keeps you safe in the vast majority of them.
Not all inputs carry equal weight. Here are the factors that have the biggest impact on your safe withdrawal amount:
Traditional calculators use a single assumed growth rate, typically 6-7%, and divide your savings accordingly. This is like planning a road trip assuming you will always drive exactly 60 mph. In reality, you hit traffic, detours, and open highway in unpredictable order.
Our AI-powered calculator works differently:
Our Process
This approach captures sequence-of-returns risk, the danger that a market crash in your first few years of retirement depletes your portfolio before it can recover, which is the number one threat to retirement plans that simple calculators ignore entirely.
The old approach to retirement withdrawals was static: pick a percentage, adjust for inflation each year, and never look back. Research now shows this is suboptimal in both directions. In good markets, you leave money on the table. In bad markets, you risk running dry.
A dynamic withdrawal strategy adjusts your spending based on how your portfolio actually performs. If the market drops 25% in your first year, you reduce spending temporarily. If your portfolio grows beyond expectations, you can spend a bit more. This flexibility dramatically improves outcomes.
Static vs. Dynamic: A Comparison
Static approach: Withdraw $40,000/year from a $1M portfolio regardless of market conditions. If the market crashes 30% in year one, you are now pulling $40K from $700K, a 5.7% rate that accelerates depletion.
Dynamic approach: Start at $40,000/year but reduce to $34,000 after a major crash. This smaller reduction in spending buys your portfolio crucial time to recover, and the math shows it can add 5-10 years of portfolio longevity.
Our calculator gives you a personalized starting point, and our monthly monitoring service helps you adjust dynamically as conditions change. Learn more about withdrawal strategies in our guide to retirement withdrawal strategies compared.

A retirement withdrawal calculator estimates how much you can safely spend each year from your retirement savings. It factors in your portfolio size, asset allocation, expected retirement length, inflation, and other income sources like Social Security to produce a personalized withdrawal amount that minimizes the risk of outliving your money.
The safe amount depends on your specific situation. While the traditional 4% rule suggests withdrawing 4% of your initial portfolio each year, modern research and current 2026 market conditions suggest 3.3% to 3.8% may be more appropriate for new retirees. Your age, portfolio mix, Social Security income, and willingness to adjust spending all influence your personal number. Use the calculator above to get a result tailored to you.
The 4% rule was developed in 1994 based on historical data that included higher bond yields (7-8%) and lower stock valuations (P/E ratios around 15x). In 2026, with bond yields around 4-4.5% and stock valuations at 22-25x earnings, many researchers recommend a lower starting rate. Our calculator uses current market data rather than historical averages to give you a more realistic recommendation.
AI-powered calculators analyze thousands of potential market scenarios rather than relying on a single average return assumption. They capture the impact of market crashes early in retirement (sequence-of-returns risk), inflation variability, and the interaction between your specific income sources and expenses. The result is a withdrawal recommendation that is robust across a wide range of possible futures, not just the average case.
