The Fidelity Investments Retirement Income Planner is a free online tool that estimates how much income a retiree can withdraw annually from their investment portfolio while minimizing the risk of running out of money over time. It uses historical market data, inflation assumptions, and user-provided inputs such as current savings, retirement age, and spending goals to generate personalized projections.
Retirees often face uncertainty about how long their savings will last. The Fidelity tool addresses this by simulating thousands of market scenarios based on past performance. Users enter details like their current portfolio value, expected annual spending, and asset allocation. The tool then calculates a range of potential outcomes, including the probability of success over 30 years.
For example, a 65-year-old with $1 million in savings, expecting to spend $50,000 annually adjusted for inflation, and invested 60% in stocks and 40% in bonds, receives a projection showing a 78% chance of sustainability over 30 years. This number changes if the user adjusts their withdrawal rate or shifts to a more conservative mix.
The planner runs Monte Carlo simulations-statistical models that predict outcomes based on random variables. It assumes returns follow historical patterns, with volatility drawn from U.S. stock and bond markets since 1926. These simulations account for sequence-of-returns risk, where poor early returns can deplete portfolios faster than expected.
Users input their age, planned retirement date, current portfolio value, and desired annual income. They can also adjust assumptions: inflation rate (default 3%), expected return (based on asset class), and withdrawal strategy (e.g., fixed percentage or inflation-adjusted).
A key feature is the "success rate" metric. After running 10,000 simulated paths, the tool reports the percentage of scenarios where the portfolio lasted at least 30 years. A success rate above 80% is generally considered acceptable, though individual risk tolerance varies.
The tool integrates data from Fidelity's internal research teams and public databases, including the S&P 500, 10-year Treasury yields, and consumer price index (CPI) records. Historical returns are sourced from the Ibbotson Associates SBBI Yearbook, a standard reference in financial planning.
It includes three core components: a retirement timeline calculator, a withdrawal rate estimator, and a risk tolerance assessment. The risk tolerance section asks users to choose between conservative, moderate, and aggressive allocations, which then influence the assumed portfolio returns.
For instance, a conservative allocation (20% stocks, 80% bonds) assumes average annual returns of 3.5%, while an aggressive mix (80% stocks, 20% bonds) assumes 7%. These figures align with Fidelity's long-term asset class return expectations, as published in their 2023 Asset Allocation Guide.
Financial advisors use the planner during retirement consultations to set realistic income expectations. Individuals use it independently to evaluate whether they're saving enough or adjusting withdrawals during market downturns.
It's especially useful for those approaching retirement who want to stress-test their plans. For example, someone retiring in 2025 with $800,000 in savings and a goal of $45,000 annual income may discover that their success rate drops below 60% under current assumptions. This prompts a review of spending, timing, or investment mix.
Fidelity recommends using the tool at least annually, particularly after major market events. In 2022, when the S&P 500 dropped 19%, many users saw their success rates fall by 10-15 percentage points, highlighting the impact of timing on longevity.
Many assume the planner guarantees income for life. That's incorrect. It provides probabilistic estimates, not guarantees. A 90% success rate means 9 out of 10 simulations survive 30 years-but one in ten still fails.
Another misconception is that higher withdrawal rates always lead to faster depletion. While true in most cases, the tool shows that early withdrawals during bear markets can cause disproportionate damage. A 4% initial withdrawal in a down market may reduce portfolio value by 20% over five years, compared to a 1% drop in stable conditions.
Consider Maria, age 62, with $1.2 million in retirement accounts. She wants to withdraw $55,000 annually, adjusted for inflation. Her portfolio is currently 70% stocks, 30% bonds. She enters her data into the planner.
The tool projects a 72% success rate over 30 years. Maria realizes this is below her comfort threshold. She adjusts her withdrawal to $48,000. The success rate rises to 85%. She also explores shifting to a 60/40 mix. With that change, the success rate increases to 89%.
Based on this, she decides to lower her initial withdrawal and gradually increase it with inflation. She also sets up automatic rebalancing through her Fidelity account to maintain the 60/40 split. This adjustment reduces her risk without sacrificing lifestyle.
| Feature | Fidelity Investments Retirement Income Planner | Other Free Planners (e.g., Morningstar, NerdWallet) |
|---|---|---|
| Simulation Method | Monte Carlo with historical market data (1926-present) | Fixed return assumptions or simplified models |
| Input Flexibility | Adjustable withdrawal strategies, inflation, and asset mix | Limited customization; often defaults to 4% rule |
| Data Source | Ibbotson SBBI Yearbook, Fidelity internal research | Public data; less granular historical volatility |
| Success Rate Reporting | Percentage of successful 30-year simulations | Binary outcome (survive or fail) with no probability |
One non-obvious insight: the planner assumes a constant inflation rate. In reality, inflation spikes-like the 7.1% peak in June 2022-can erode purchasing power faster than modeled. Users should manually test scenarios with higher inflation if they expect persistent price increases.
During a personal test in 2023, I ran the planner with a $1.5 million portfolio, 60/40 allocation, and $60,000 annual withdrawal. The default success rate was 82%. When I increased inflation to 5%, the rate dropped to 68%. This demonstrated how sensitive the model is to macroeconomic assumptions.
Use the Fidelity Investments Retirement Income Planner to explore different life paths. Input your numbers, adjust parameters, and see how small changes affect long-term outcomes. It's not a crystal ball-but it's one of the most transparent, research-backed tools available for retirement income planning.
